经常问的问题


信号完整性

Connector Selection

如何选择一个连接器,这是他们的设计足够?
要考虑的项目包括连接器性能,路由效率和引脚密度。有关更多信息,请联系我们信号完整性支持.
我们如何解决这个问题,“这连接吗or work in my design"?
有关应用程序的以下信息将有助于确定连接器系统是否满足信号完整性要求:-系统拓扑:点对点、多点、点对多点、星形等-终端类型:并行(一端/两端)、产品、有源、RC、无-时钟/数据恢复:同步、异步、,源同步,CDR-信号类型:单端或差分-数据编码:二进制、PAM-2、PAM-4等-信号技术:示例包括LVTTL、SSTL-2、Rambus、LVDS、PECL、CMOS,GTL+-信号数据速率:以Mbps或Gbps为单位指定-信号边缘速率:指定10/90或20/80-系统阻抗-以欧姆为单位指定以及公差(例如+/-10%)-串扰要求:在接收器处指定(以电压摆幅的%或dB为单位)-倾斜以提出建议。有关更多信息,请联系我们的信号完整性支持.
连接器的堆叠高度是否会产生速度差异?
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 our信号完整性支持.
最佳信号接地比是多少?
信号到接地比为1:1通常是最佳的,但对于具有小于1:1的大引脚阵列的连接器,可能需要用于可靠的高速单端操作。有关更多信息,请联系我们信号完整性支持.
Are there any recommendations for the best performance when using high speed differential connectors?
对于以2.5 Gbps及以上运行的差动连接器,对对的地面屏蔽可能非常有益。有关更多信息,请联系我们信号完整性支持.
Does a connector have one impedance?
不。A connector's impedance profile changes with respect to change in signal-to-ground ratio. The "exposure" of the impedance discontinuities within the connector is dependent on the edge/fall rate of the signal propagating through the connector.
连接器的阻抗轮廓是否相对于系统阻抗更改?
不。The impedance discontinuities inherent to the connector’s design are independent of the characteristic system impedance.
我能用你们的高速连接器来分配电源吗?
Yes; here are some guidelines for assigning pins for power distribution:
  • 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.

电磁建模

Samtec提供什么类型的连接器模型结构?
Samtec提供单线和多线结构。该模型代表配合连接器(雄性和母线连接器或插入边缘卡的载体边缘连接器)。
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。
我可以使用单行模型进行哪种类型的分析?
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.)
我可以用多线模型进行什么类型的分析?
多线型号可用于分析 - 传播延迟, - 衰减, - 反射, - 驱动功率, - 时序 - 静电耦合 - 电磁耦合 - 共模噪声 - 串扰。
Samtec采用什么过程进行连接器模型?
Samtec雇佣了一个行业证明梯子集中element modeling process. The elements are derived using 2D field solver software. Samtec is also investigating other modeling techniques (e.g., full 3-D modeling, measurement-based modeling) which would be better suited for more complex structures (e.g., cable assemblies, flex circuits).
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)。
Does Samtec validate their connector models?
Samtec的Connector Model的分类为以下之一: - 验证:使用Samtec定义的建模技术创建的模型。模拟模型数据与来自连接器的测试数据相关联。- 开发:使用Samtec定义的建模技术创建的模型,但尚未与测试数据相关联。这些模型可以是“软验证”,其中来自模型的仿真数据与从全波3D模拟获得的数据相关。- 估计:使用工程近似创建模型(例如,与已经建模的另一个连接器的设计相似之处)。
What CAE vendor formats does Samtec provide connector models for?
Samtec支持以下仿真工具,带有连接器型号:Synopsis Hspice,Cadence Pspice,Mentor Graphics ICX(MMF格式),Cadence SpectRraquest Sigxplorer(DML格式),HyperlyNX Linesim(SLM格式)和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是宜必思开放论坛的积极成员,并计划在批准IBIS ICM规范的情况下致力于提供真正的IBIS模型。迄今为止,Samtec开发了“SLM_GENERAL”ICM模型。其他ICM型号类型的可用性将取决于将Ibis ICM兼容模型导入其模拟包的模拟软件供应商能力。
如果我没有看到用于连接器的连接器模型,我会感兴趣吗?
联系我们信号完整性支持和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?
Samtec的高速表征测试报告中的数据反映了50欧姆单端和100欧姆差分环境中的性能。连接器如何在其他特征阻抗环境中进行平凡(系统驱动电路,迹线和终止方案的实体 - 设计为相同的特征阻抗)?
  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. 通过连接器的传播延迟不会改变,因为连接器设计所固有的电感和电容性质独立于特征系统阻抗。
  3. 串扰(电压摆动的百分比)不会受到影响。串扰是电路之间的耦合的量度,并且由于连接器内的电感和电容耦合而是由于连接器。连接器设计所固有的耦合特性独立于特征系统阻抗。
  4. Insertion and Return Loss may be affected. As system characteristic impedance changes, the overall impedance mismatch between the system and connector may vary. This causes a change in the reflection coefficient caused by the connector; which would result in a change in return loss and insertion loss.

EMI.

Samtec连接器满足FCC B类EMI要求吗?
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.
屏蔽连接器和电缆组件有助于减少排放,提高电子产品的免疫力吗?
是的,他们可以帮助,在某些情况下大大。具有周期性切换的信号,例如时钟线是经典噪声源。如果来自这种类型的源的能量耦合到退出屏蔽外壳的电缆,则电缆可以像电池电话天线辐射一样辐射耦合的噪声(尽管没有有效)。将屏蔽放在电缆上(并正确终止屏蔽)可以显着降低辐射的发射。对于电路板内部连接器内部连接器,外壳中的情况类似,除了外壳内部发生辐射发射,以便在EMI测试期间可能或可能不可见。
Q2™产品与Q系列™产品相比,Q2™产品有多少屏蔽?
测试结果表明,在1-4ghz频率范围内提高了10-20db,在4-10ghz频率范围内提高了0-10db。这是一个比较试验,其中屏蔽连接器的辐射场(Q2™) 与非屏蔽连接器(Q系列)的辐射场进行了比较™). 一个有意义的测试的关键是测试设置和测试板上的所有变量对于两个测试都需要相同。全波模拟结果表明,在1-10ghz频率范围内,系统的性能也提高了10db左右。
使用电路板(BTB)连接器时,减少EMI的最佳实践是什么?
在回答这个问题之前,需要在前面进行一些假设:
  • 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)。
重要的是要理解BTB系统中的辐射机制或显性EMI天线。一种正常运行的一个类比是将PCB接地平面视为微带贴片天线的元素。在连接器上产生的任何纵向电压显示为用于驱动PCB接地平面的电压源,与驱动微带贴片天线的馈电元件不同。这是一个有用的低频(50 MHz至100次MHz)近似;在较高频率下,辐射系统更复杂,但最佳实践保持不变。
为了最小化连接器上的纵向电压电位,我们需要最小化信号返回路径的自部分电感。需要一些简短的术语定义:
  • 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:
  • 短的BTB堆叠高度比高的BTB堆叠高度好。通过将接地插脚集成到信号插脚场(1:1),使连接器中的环路面积最小化。信号回传采用宽扁导体,专用平面优于引脚,使信号和接地模式的特性阻抗尽可能低。
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.
电子产品的最佳EMI策略是考虑多个领域,如PCB设计(堆叠和电路布局),连接器选择,信号返回管理(接地),电力滤波(去耦/ PI设计)和逻辑选择,并强调扩频时钟和边缘整形。

Samtec是否有在线互连处理资源?
参观加工文献页面有关以下内容的深入信息。
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:Bob Willis的粘贴孔回流, and other helpful information on our加工文献页面下的“粘贴”菜单中的“粘贴”菜单。
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公司.

rohs和无铅

什么是elv,weee,rohs和penta / octa?
ELV - (EU Directive 2000/53/EC) The End of Life Vehicles Directive aims to reduce the amount of environmentally unfriendly waste from ELVs.
WEEE(欧盟指令2002/96 / EC)废物电气和电子设备的指令。
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(欧盟指令2003/11 / EC)该指令禁止使用五角队和八面峰。该指令目前在欧盟生效。两种禁用的物质是阻燃剂(五溴二苯醚和八溴甲醚二苯基醚)。
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.
为什么禁止铅?
铅只是6种禁止物质中的1个。但由于它有许多不同的用途铅是电子和电气设备制造商的RoHS指令中最突出的物质。铅是焊料的芯部件,用于制造印刷电路板(PCB)。PCB越来越多地用于日常家庭物品,从占用者到DVD播放器,越来越多地发现了世界各地的垃圾填埋场。雨水的酸度洗涤焊料引线来自碎PCB。铅最终最终可能最终饮用水供应。铅可以影响身体中的几乎任何器官和系统。最敏感的是中枢神经系统,特别是在儿童中。铅也可以损害肾脏和生殖系统,导致贫血。
这个立法是否全球?
While the implementation deadlines form part of the EU legislation, the need to comply will evolve globally. It is unlikely that electronics manufacturers will make "lead free" components for Europe and lead-based components for the rest of the world.
Does this affect Samtec products?
Yes, but it depends on the part number. WEEE impacts packaging materials as well as products.
做Samtec产品含有大量的镉,Hexavalent Chromium, Mercury, Lead, Polybrominated Biphenyls (PBBs), Polybrominated Diphenyl Ethers (PBDEs), PentaBDEs or OctaBDEs?
Generally speaking Samtec products do not contain Hexavalent Chromium, Mercury, PBBs, PBDEs, PentaBDEs or OctaBDEs. It is possible unintentionally added, inherent, trace or near trace amounts of Cadmium and Lead may be contained in Samtec products. At this time, Samtec cannot claim that all packaging materials are compliant with the RoHS and/or WEEE Directives.
您是否有没有关于无铅环境问题的政策声明?这是可用的吗?
是的。您还可以下载最新的Samtec环境政策文件在这里.
Samtec是否会为其产品提供正式的RoHS CoC(合格证书)?
Yes, upon request, Samtec will provide a formal CoC. Please provide Company name and address as well as Company contact and contact information of the person requesting the CoC along with valid Samtec part numbers to ourGeneral Technical Support Group.
What lead-free plating is available on Samtec products?
我们的大多数电镀是无铅和/或符合RoHS的。CLX产品或预接电的任何接触可能不符合符合要求。根据部件号,电镀呼叫和处理温度,您可能需要选择哑光锡饰面。明亮的酸锡将在无铅回流焊接的升高的加工温度下褪色,需要改变到哑光锡(TM,LM,FM或SM电镀)。电镀选项应列在目录和/或打印上。
Is Samtec’s gold plating always lead-free and RoHS compliant?
Yes, Samtec’s gold plating is always lead-free and RoHS compliant (pre-plated or in house plated).
Are there any other technical or product specifications that are likely to be affected?
这取决于部件号。If a part contains 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.
Are Samtec lead-free parts compatible with the elevated temperatures of lead-free processing?
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.
你们无铅产品的MSL(湿度敏感度)等级是什么?你们的零件符合J-STD-020C吗?
J-STD-020C是指SMT电气部件的湿度敏感性。与RoHS指令没有关系或连接。一般来说,MSL不是SAMTEC部件的关注。我们将所有SMT部件分类为MSL级别1. J-STD-020C不适用于通孔部件。
贵公司的无铅零件/包装是否标明无铅,是否符合JEDS97的规定?
截至2005年10月,Samtec在大多数产品的最低水平运输集装箱上提供指令合规标签。
您是否打算改变您的分码系统以反映无铅的变化?
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.
当介绍无铅零件时,您有明确的日期吗?
The majority of Samtec’s products are, or always have been, free of intentionally added lead unless specified otherwise by the customer. However, there are several products that are not currently compliant or have exceptions.
IDSD/IDMD/HCXX cable assemblies - not compliant - expected to be compliant by late November 2005. The connector ends (plastic, pins and plating) are compliant.
具有铅焊料的HDR产品不合规 - 可以特殊订购,因为无铅和符合RoHS。
如果焊料球包含在零件标注中,则任何焊料球产品都不符合要求(无当前替代无铅、符合RoHS标准的焊料球)。
I-O products are not compliant (a few exceptions)....must check each part number to see if we have material information or declaration.
使用预镀PIN的标准“CLX”产品不符合符合(必须检查部件号以确认状态)。
任何包含电线,电缆,螺栓,螺栓,金属屏蔽等硬件的产品都是可疑的,应该验证。
无铅产品的交货期会增加吗?
不。
Will there be an increase in the price of lead-free products?
不。
Are there any plans to obsolete any parts due to lead-free?
不。
材料声明是否可用于无铅产品?我如何到达他们?
是的。Currently, material declarations for the majority of Samtec products are available on our website. This accounts for 80% of the top selling products.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.
您的产品是否与PB汇编程序(向后兼容)兼容?
是的。
您的产品是否与无铅加工兼容?
这取决于零件号。零件的组成决定了加工兼容性。您必须确定零件是否没有故意添加的铅,并确保绝缘体和镀层表面能够承受较高的加工温度。
您是否声称任何零件的豁免?
是的。具有黄铜组件(如黄铜对准销)的部件可以含有有意添加的铅。黄铜组分(铜合金)在4.0wt内含有一定量的有意添加的铅。电子元器件中铜合金的RoHS指令的百分比。
Who is your specific contact /Project Manager regarding any technical or other issues?
Dick Bowyer是主要的联系,但请指导所有询问General Technical Support group.

哑光田

哑光镀锡和明亮锡电镀有什么区别?
主要差异是:
  • Temperature compatibility - Matte Tin is compatible with the elevated temperatures of lead-free, reflow processing (250-260C). Bright Tin has a tendency to discolor (turn dark) when exposed to the higher lead-free, reflow processing environment.
  • 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.
I am transitioning to lead-free processing. Why should I choose Matte Tin?
哑光田is readily available and has a successful track record of reliability.
哑光田is compatible with all existing lead-alloy and Pb-free solders and pastes.
磨砂锡耐受无铅加工所需的较高过程温度。
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。
哑光锡和明亮锡的组成是什么?
Samtec采用的哑光镀锡和光亮镀锡基本上是100%纯锡。Samtec使用的哑光锡含有约0.015%的共沉积有机物,而光亮锡含有约0.15%的共沉积有机物。
与欧盟RoHS指令符合哑光锡和明亮的锡指令吗?
由Samtec应用的磨砂锡和亮锡夹符合RoHS指令(指令2002/95 / EC)。
Is Matte Tin compatible with leaded solder processes?
哑光田is backward compatible with leaded solder processing.
Will Matte Tin prevent Tin Whiskers from forming?

Can I continue to order product with Tin-lead plating?

Will I receive a mixed shipment containing some Matte Tin plated parts and some Bright Tin plated parts?
编号产品将在客户订单中携带由部件呼叫指定的电镀。
