经常问的问题


Signal Integrity

Connector Selection

How does one go about selecting a connector that is sufficient for their design?
Items to be considered include connector performance, routing efficiency, and pin density. For more information, contact ourSignal Integrity Support
我们如何解决这个问题,“这连接吗or work in my design"?
The following information about your application will help determine if a connector system can meet the signal integrity requirements: - System Topology: point-to-point, multi-drop, point-to-many-point, Star, etc - Termination Type: Parallel (one/both ends), Products, Active, RC, none - Clocking/Data Recovery: synchronous, asynchronous, source synchronous, CDR - Signaling Type: Single-Ended or Differential - Data Encoding: Binary, PAM-2, PAM-4, etc - Signal Technology: examples include LVTTL, SSTL-2, Rambus, LVDS, PECL, CMOS, GTL+ - Signal Data Rate: specified in Mbps or Gbps - Signal Edge Rate: specify 10/90 or 20/80 - System Impedance - specified in ohms along with tolerance (e.g., +/- 10%) - Crosstalk Requirements: specified at receiver (in % of voltage swing or dB) - Skew to make educated recommendations. For more information, contact ourSignal Integrity Support
Does the stack height of the connector make a difference in its speed?
Always choose the shortest connector that can do the job. The shorter the connector, the shorter period of time for reflections and crosstalk to act, and the better the signal quality. For more information, contact ourSignal Integrity Support
What is the optimal signal-to-ground ratio?
A signal-to-ground ratio of 1:1 is usually optimal, but for connectors with large pin arrays signal-to-ground rations of less than 1:1 may be required for reliable high speed single-ended operation. For more information, contact ourSignal Integrity Support
使用高速差分连接器时是否有最佳性能的建议?
For differential connectors running at 2.5 Gbps and above, ground shielding of the pairs can be very beneficial. For more information, contact ourSignal Integrity Support
Does a connector have one impedance?
不可以。连接器的阻抗轮廓相对于信号到接地比的变化而改变。连接器内的阻抗不连续性的“曝光”取决于通过连接器传播的信号的边缘/下降速率。
Does a connector’s impedance profile change relative to system impedance changes?
No. The impedance discontinuities inherent to the connector’s design are independent of the characteristic system impedance.
Can I use your high speed connectors to distribute power?
是;以下是用于分配PIN的指示:
  • If the connector has ground blades (e.g., Q-products) that are used to distribute power through the connector, and the connector is used for high-speed signaling, then the following should be done: All signals passing through that section of the connector should be referenced to the same power plane being passed through the connector on both sides of the board, OR if referenced to ground, the power plane should be adjacent and close to the ground plane on both PCBs. This recommendation will ensure that the signal return path is unbroken across the connectors, increasing bandwidth and decreasing EMI.
  • If signal pins are used to distribute power through the connector, they should be placed considering the noise which can occur due to signal coupling. Signal pins passing power and ground are as susceptible to noise as any signal pin would be. Sensitive power signals should be well isolated with grounds on either side to reduce crosstalk. And for low noise power, such as a precision voltage reference, it may be necessary to isolate the power pin with multiple grounds on either side, and on the back side of the connector.

Electromagnetic Modeling

What types of connector model structures does Samtec offer?
Samtec.offers single-line and multi-line structures. The models represent MATED connectors (male and female connectors or card edge connector with edge card inserted).
How do single-line models (SLM) differ from multi-line models (MLM)?
SLM用于评估单个连接器引脚的效果。SLM独立于连接器布线图案,并且是良好的参考连接器的近似值。MLM与SLM的不同之处在于它考虑了静电和电磁耦合,以及连接器中的共同阻抗噪声。它的结构在三维中互相耦合到彼此的所有引脚。这导致一种复杂的模型,其使用产品电阻,电感,耦合电容和电感耦合系数,使得允许在输入和输出中的连接。该建模有效地示出了耦合噪声。但是,这是以CPU运行时为代价完成的。
What type of analysis can I do with a Single-Line Model?
Single-Line models can be used to analyze - propagation delay, - attenuation, - reflections, - drive power, - timing. A SLM CAN NOT BE USED TO EVALUATE CROSSTALK! (FOR CROSSTALK - A MULTI-LINE MODEL MUST BE USED.)
What type of analysis can I do with a Multi-Line Model?
Multi-Line models can be used to analyze - propagation delay, - attenuation, - reflections, - drive power, - timing - electrostatic coupling - electromagnetic coupling - common mode noise - crosstalk.
What process does Samtec employ for making connector models?
Samtec采用业界经过验证的梯子集成元素建模过程。使用2D字段求解器软件导出元素。Samtec还在研究其他建模技术(例如,完整的3-D建模,基于测量的模型),这将更适合更复杂的结构(例如电缆组件,柔性电路)。
How can I view your connector models?
The models are text files that can be viewed with any text editor.
What are the "boundaries" of your connector models?
通常,SMT连接器边界被定义为从阳连接器的SMT尾部到母连接器的SMT尾部(不包括SMT垫)。对于T / H连接器,边界被定义为从阳连接器的PCB表面到母连接器的PCB表面。对于所有连接器模型,不包括终端,驾驶源和寄生电容。对于卡边缘连接器,边界被定义为从连接器的SMT尾部(或用于T / H的PCB表面)到边缘卡焊盘的路线侧(包括边缘卡垫)。
Samtec是否验证了其连接器模型?
Samtec.’s connector model’s are classified as one of the following: - Validated: Model created using Samtec’s defined modeling techniques. Simulation data from the model correlates with test data from the connector. - Developmental: Model created using Samtec’s defined modeling techniques, but has not yet been correlated against test data. These models may be "soft validated", where simulation data from the model is correlated with data obtained from a full wave 3D simulation. - Estimated: Model was created using engineering approximations (e.g., design similarities with another connector that has been modeled).
What CAE vendor formats does Samtec provide connector models for?
Samtec.supports the following simulation tools with connector models: Synopsis HSPICE, Cadence PSPICE, Mentor Graphics ICX (MMF format), Cadence SPECCTRAQuest SigXplorer (DML format), HyperLynx LineSim (SLM format), and HyperLynx 7.5 ELDO.
Will Samtec’s HSPICE and PSPICE models work with other SPICE-based simulation engines?
Yes, the structure of the SPICE connector model is such that it should run in simulators based on Berkeley SPICE 3F5.
Does Samtec offer IBIS models?
The IBIS Interconnect Modeling Specification (IBIS ICM 1.0) was approved on September 12, 2003 (http://www.eda.org/pub/ibis/connector/)。Samtec.is an active member of the IBIS Open Forum and plans on working towards providing true IBIS models now that the IBIS ICM specification has been approved. To date, Samtec has developed "SLM_general" ICM models. Availability of other ICM model types will be dependent on the simulation software vendors ability of importing IBIS ICM compatible models into their simulation packages.
What if I do not see a connector model available for the connector I am interested in?
联系our Signal Integrity Support and communicate your need for a model. We will work with you to help assess what is required and then add the request to our model production schedule.

高速表征测试

Samtec如何为信号完整性性能“速率”它们的连接器?
The data in Samtec’s High Speed Characterization Test Reports reflects performance in 50 ohm single-ended and 100 ohm differential environments. How differently will the connector perform in other characteristic impedance environments (where the entities of the system - drive circuit, traces, and termination schemes - are designed to the same characteristic impedance)?
  1. Impedance profile of the connector will not change, because the impedance discontinuities inherent to the connector’s design are independent of the characteristic system impedance.
  2. Propagation delay through the connector will not change because the inductive and capacitive properties inherent to the connector’s design are independent of the characteristic system impedance.
  3. Crosstalk (percentage of voltage swing) will not be affected. Crosstalk is a measure of the coupling between circuits, and is due to inductive and capacitive coupling within the connector. The coupling properties inherent to the connector’s design are independent of the characteristic system impedance.
  4. 插入和返回损耗可能会受到影响。随着系统特性阻抗的变化,系统和连接器之间的整体阻抗不匹配可以变化。这导致由连接器引起的反射系数的变化;这将导致回报损耗和插入损耗发生变化。

EMI

Samtec.connectors meet FCC Class B EMI Requirements?
Federal requirements (FCC 47 CFR Part 15, EN55022, etc.) require EMI compliance testing of active electronic systems such as computers. While passive components can impact the overall system level EMI performance, it is not possible to directly test a connector, cable assembly, resistor, or bolt for EMI compliance.
Shielded connectors and cable assemblies help reduce emissions and improve immunity of electronic products?
Yes they can help, and in some cases dramatically. Signals that have periodic switching such as clock lines are a classic noise source. If energy from this type of source couples to a cable that exits a shielded enclosure, the cable can radiate the coupled noise much like a cell phone antenna radiates (although not as efficiently). Placing a shield over the cable (and terminating the shield properly) can reduce the radiated emissions dramatically. For a board to board connector inside an enclosure, the situation is similar except the radiated emission occurs inside the enclosure so the radiated emission may or may not be visible during an EMI test.
How much shielding does the Q2™ products have compared to Q Series™ products?
Testing showed an improvement of 10-20 dB over the frequency range of 1-4 GHz and 0-10 dB from 4-10 GHz. This was a comparison test where the radiated field of the shielded connector (Q2™) was compared to the radiated field of an unshielded connector (Q Series™). The key to a meaningful test is that all variables in the test setup and on the test board need to the same for both tests. Full wave simulation showed an improvement of approximately 10 dB over the 1-10 GHz frequency range as well.
What are the best practices to reduce EMI when using a board to board (BTB) connector?
There are a few assumptions that need to be stated up front before we get into answering this question:
  • 我们正在寻址如Samtec QSE / QTE或SEA / SEAF产品,而不是用于BTB应用的同轴RF连接器,我们主要对跨越KBPS到GBPS数据速率的数字应用感兴趣。我们没有解决非常低频模拟(音频)类型应用程序。连接器是整体互连系统的一部分,可以包括印刷电路板(PCB)。
It is important to understand the radiation mechanism or dominant EMI antennas in a BTB system. One analogy that works well is to consider the PCB ground planes as elements of a microstrip patch antenna. Any longitudinal voltage potential developed across the connector appears as a voltage source which serves to drive the PCB ground planes, not unlike a feed element driving a microstrip patch antenna. This is a useful low frequency (50 MHz to 100’s of MHz) approximation; at higher frequencies the radiating system is more complex but the best practices remain the same.
To minimize the longitudinal voltage potential across a connector, we need to minimize the self-partial inductance of the signal return path. Some brief terminology definitions are needed:
  • Loop inductance is the only inductance that is “real" or can be measured. Self-partial inductance is a useful mathematic construct; it can be calculated but not directly measured. “Self" means we are interested in the magnetic flux developed from only one conductor of the loop. “Partial" means we are looking at only a portion of the path, specifically the portion between the PCBs.
为了最大限度地减少连接器上的自部分电感,有一些一般的原则可以遵循:
  • A short BTB stack height is better than a taller BTB stack height. Minimize the loop area in the connector by having ground pins integrated into the signal pin field (1:1). Use broad, flat conductors for signal return, dedicated planes are superior to pins for signal return Make the characteristic impedance of the signal and ground pattern as low as possible.
如果EMI是唯一的问题,BTB连接器应具有非常低的特性阻抗(<1Ω)。信号和返回电流的平面分布将具有跨连接器的最低自体部分电感和最低的EMI。显然这不是一个实用的指导,因为数据传输要求决定与系统阻抗(通常为50Ω)关闭匹配。
The same physics that applies to EMI reduction in BTB connectors also apply to PCBs. Disruptions in the signal return path such as splits in the ground plane drastically increases the self partial inductance of the return path which can lead to EMI problems.
最好的电子产品是consid EMI策略er multiple areas such as PCB design (stackup and circuit layout), connector selection, signal return management (grounding), power filtering (decoupling/PI design) and logic selection with an emphasis on spread spectrum clocking and edge shaping.

Visit the加工文学page for in-depth information on the following and more.
Does Samtec have information on Paste In Hole (PIH) Processing?
Paste In Hole technology employs the same techniques for through-hole soldering as those used for standard surface mount connectors and components. Samtec provides the recommended stencil aperture and plated through-hole sizes for most connector products capable of being processed using Paste In Hole technology on the connector footprint. To be a candidate for Paste In Hole soldering, a connector must have an insulator body material capable of withstanding lead and/or lead-free reflow temperatures, and vertical and horizontal clearance around leads large enough to allow adequate printed solder paste volume. For more information on Paste In Hole processing, see this eBook:Paste in Hole Reflow by Bob Willis, and other helpful information on our加工文学下面的页面‘Paste In Hole Processing’ menu.
Does Samtec have any recommendations for processing multiple fine pitch SMT connectors on a single board?
The majority of Samtec’s vertical board-to-board connectors are capable of being used in applications where multiple connectors are placed on a single board and mated simultaneously. When using multiple connectors per board, there is a higher potential for misalignment. To prevent this issue, closely follow Samtec’s recommended footprint and stencil designs, ensure a good solder print, machine place the components, and hold the drill diameter tolerances for the alignment pin holes to +/- .002" [0.05 mm]. Each connector product has a unique maximum recommended misalignment in the X and Y directions to ensure a good mate. For the maximum X and Y misalignment of a specific product, please contactIPG

RoHS and Lead-Free

What are ELV, WEEE, RoHS and Penta/Octa?
ELV - (欧盟指令2000/53 / EC)寿命终结器指令旨在减少ELV的环境不友好的浪费金额。
WEEE (EU Directive 2002/96/EC) The Directive on Waste Electrical and Electronic Equipment.
RoHS (EU Directive 2002/95/EC) The Reduction of Certain Hazardous Substances. Lead, Cadmium, Mercury, Hexavalent Chromium, Polybrominated Biphenyls (PBBs) and Polybrominated Diphenyl Ethers (PBDEs) are banned from most electronic products offered for sale in Europe effective July 1, 2006.
Penta/Octa (EU Directive 2003/11/EC) This directive bans the use of PentaBDEs and OctaBDEs. This directive is currently in effect in EU. The two banned substances are fire retardant additives (Pentabromo diphenyl ether and Octabromo diphenyl ether).
What is driving the move to RoHS compliant/lead free (Pb-free) products?
In an effort to reduce the amount of electronic waste spreading across European landfills, the European Union (EU) has banned most electronic products containing intentionally added lead and other hazardous chemicals.
Why ban lead?
Lead is only 1 of 6 banned substances. But because it has many different uses lead is the most prominent substance detailed in the RoHS directive for Electronic and electrical equipment manufacturers to be concerned about. Lead is a core component of the solder that goes into the manufacture of printed circuit boards (PCBs). PCBs are increasingly used in everyday household items, from toasters to DVD players and are increasingly finding their way into landfills across the world. The acidity of rainwater washes the solder lead from crushed PCBs. The lead can eventually end up in drinking water supplies. Lead can affect almost any organ and system in the body. The most sensitive is the central nervous system, particularly in children. Lead can also damage the kidneys and reproductive system, and cause anemia.
Is this legislation global?
虽然实施截止日期是欧盟立法的一部分,但遵守的需要将在全球范围内发展。电子产品制造商不太可能为欧洲和铅基组件为世界其他地区进行“无铅”组件。
这会影响Samtec产品吗?
Yes, but it depends on the part number. WEEE impacts packaging materials as well as products.
SAMTEC产品含有镉,六价铬,汞,铅,多溴联苯(PBB),多溴二苯醚(PBDES),戊巴比斯或八峰吗?
一般来说,Samtec产品不含六价铬,汞,PBB,PBDE,五角队或八面峰。可以在Samtec产品中包含无意地添加,固有,痕量或接近痕量的镉和铅。此时,Samtec不能声称所有包装材料符合RoHS和/或WEEE指令。
Do you have a policy statement on the lead-free environmental issue? Is this available on-line?
是。You may also download the latestSamtec.Environmental Policy documentation here
Will Samtec provide a formal RoHS CoC (Certificate of Compliance) for their products?
是的,根据要求,Samtec将提供正式的COC。请提供公司名称和地址以及公司联系人和联系人信息,要求COC与我们的有效的Samtec部件号一般技术支持小组
What lead-free plating is available on Samtec products?
The majority of our plating is lead free and/or RoHS compliant. CLX products or any contact that is pre-plated may not be compliant. Depending on the part number, plating call out and the processing temperatures you may need to choose a Matte Tin finish. Bright Acid Tin will discolor at the elevated processing temperatures of lead-free, reflow soldering and will need to be changed to Matte Tin (TM, LM, FM or SM plating designations). The plating options should be listed in the catalog and/or on the print.
Samtec的镀金总是无铅和符合RoHS吗?
是的,Samtec的镀金始终是无铅,符合RoHS(预镀或镀覆)。
是否有可能受到影响的其他技术或产品规格?
这取决于数量。如果一个部分包含s intentionally added lead, or if the processing temperatures are increased and the current insulator can’t withstand those temperatures, the composition of the part must be altered to accommodate the elevated temperatures and eliminate the intentionally added lead (unless there is an approved Directive exemption as in the case with the brass alignment pins). This would require a part number change.
Samtec无铅部件是否兼容无铅加工温度升高?
这取决于部件编号。在马的左手rgin of the catalog pages under specifications, you will find the processing information. Reflow processing will need a high temp body and matte tin finish. Samtec recommends through hole parts that have a high temp insulator be changed to matte tin as well.
What is the MSL (Moisture Sensitivity Level) classification of your lead-free products? Do your parts comply with J-STD-020C?
J-STD-020C refers to the moisture sensitivity of SMT electrical components. There is no relation or connection to the RoHS Directive. Generally speaking, the MSL is not a concern for Samtec parts. We classify all of our SMT parts as MSL Level 1. J-STD-020C is not applicable for through hole parts.
Will your lead-free parts / packaging be marked lead-free, do you comply with JEDS97?
As of October 2005, Samtec is providing a Directive compliancy label on the lowest level shipping container for the majority of products.
Are you intending to change your part-numbering system to reflect a change to lead-free?
这取决于部件编号。If the part contains intentionally added lead or if higher processing temperatures will be used, you will need to ensure the plating finish and the insulator can withstand the elevated temperatures. In those cases yes, a part number change will be required.
Do you have a definitive date when lead-free parts will be introduced?
除非客户另有规定,否则大多数Samtec的产品都是或始终是无意添加的领导。但是,有几种目前不符合或具有异常的产品。
IDSD / IDMD / HCXX电缆组件 - 不符合 - 预计到2005年11月下旬符合要求。连接器结束(塑料,引脚和电镀)兼容。
HDR products with leaded solder not compliant - can be ordered special as lead-free and RoHS compliant.
Any solder ball product is not compliant if the solder balls are included in the part call-out (no current alternate lead-free, RoHS compliant solder ball).
I-O products are not compliant (a few exceptions)....must check each part number to see if we have material information or declaration.
Standard "CLX" products that use pre-plated pins are not compliant (must check part number to confirm status).
Any product containing wire, cable, hardware such as screws, nuts, bolts, metal shields is suspect and should be verified.
Will there be an increase in lead times for lead-free products?
No.
无铅产品的价格会增加吗?
No.
是否有任何计划在没有铅的情况下过时?
No.
Are material declarations available for your lead-free products? How do I get to them?
是。目前,我们的网站上提供了大多数Samtec产品的材料声明。这占顶级销售产品的80%。无铅产品材料申报
Why are you recommending a change to Matte Tin plating?
A plating containing bright acid tin can discolor when exposed to the higher processing temperatures of lead-free, reflow soldering. Therefore it is recommended that the BAT be changed to change to Matte Tin. We are recommending that through hole parts with high temp insulators also be changed to a matte tin finish.
Are your products compatible with Pb assembly procedures (backwards compatible)?
是。
Are your products compatible with Lead Free processing?
这取决于数量。The composition of the part determines the processing compatibility. You must determine if the part is free of intentionally added lead as well as ensuring that the insulator and plating finish can withstand the elevated processing temperatures.
Are you claiming exemptions for any parts?
是。Parts with brass components (such as brass Alignment pins) may contain intentionally added lead. The brass components (a copper alloy) contains a quantity of intentionally added lead within the 4.0 wt. % exemption of the RoHS Directive for copper alloys in electronic components.
谁是您的特定联系人/项目经理关于任何技术或其他问题?

Matte Tin

What is the difference between Matte Tin plating and Bright Tin plating?
The primary differences are:
  • 温度兼容性 - 哑光锡与无铅回流加工的高温(250-260℃)相容。明亮的锡在暴露于较高的无铅回流处理环境时具有褪色(变黑)的趋势。
  • Grain size - Matte Tin has a larger grain size than Bright Tin.
  • Appearance - Matte Tin has a normal whitish "matte" surface appearance whereas Bright Tin has a bright (shiny) surface finish.
我正在转换到无铅处理。我为什么要选择哑光锡?
Matte Tin is readily available and has a successful track record of reliability.
磨砂锡与所有现有的铅合金和无铅焊料兼容。
Matte Tin tolerates the higher process temperatures required for lead-free processing.
哑光锡的粒径较大(与亮锡相比)在电镀中产生较小的应力。纯锡镀膜中的应力可以是锡须形成和生长的根本原因。
哑光锡和明亮的Ti的构成是什么n?
The Matte Tin and Bright Tin platings applied by Samtec are essentially 100% pure Tin. The Matte Tin applied by Samtec contains approximately 0.015% co-deposited organics as opposed to Bright Tin with approximately 0.15% co-deposited organics.
Are Matte Tin and Bright Tin compliant with the European Union RoHS Directive?

Is Matte Tin compatible with leaded solder processes?
哑光锡与铅焊接加工兼容。
哑光锡将防止锡晶片成形?
No high-Tin plating process can claim to be whisker-free. Copper/copper-alloy lead frames plated on a Nickel diffusion barrier are highly whisker resistant.

The thickness of the Matte Tin plating is part specific. The majority of products will have a minimum 150 micro-inch to 350 micro-inch plating thickness.
Is there a price penalty for Matte Tin?
目前,Samtec无法预测明亮锡和哑光锡之间的价格差异。
Will specifying Matte Tin impact my lead times?
The lead times for the majority of Samtec products will not be affected by specifying Matte Tin plating.

Can I continue to order product with Tin-lead plating?
与我们过去的历史一致,它是Samtec的目的,继续支持要求锡铅电镀的客户。锡铅电镀指示器“-tl”(锡铅)和“-stl”(选择性锡铅)将保持有效的电镀设计器,用于部分呼叫。
我会收到一个混合的装运,其中包含一些哑光镀锡件和一些明亮的镀锡件吗?
No. Product will be shipped bearing the plating specified by the part call-outs in the customer order.
