Typical properties for CHO-SEAL 1310 and 1273 materi-al are shown on pages 33 and 32respectively.High Shielding PerformanceCHO-SEAL 1310 material provides more than 80 dB of shielding effectiv-ness from 100 MHz to 10 GHz, while CHO-SEAL 1273 material provides more than 100 dB.Low Volume ResistivityBoth materials have exceptionally low volume resistivity, which makes them well suited for grounding appli-cations in which a flexible electrical contact is needed.Low Compression GasketSpacer gaskets are typicallydesigned to function under low deflec-tion forces. Chomerics uses design tools such as Finite Element Analysis (FEA) to accurately predict compres-sion-deflection behavior of various cross section options. Refer to page16.LCP Plastic SpacerLiquid crystal polymer (LCP)spacers, including those made with Vectra A130 material, provide aCHO-SEAL ®1310 or 1273Conductive ElastomersWith EMI spacer gaskets, shielding and grounding are provided by Chomerics’CHO-SEAL 1310 and 1273 conductive elastomers, specifi-cally formulated for custom shape molded parts. They provide excellent shielding and isolation against electro-magnetic interference (EMI), or act as a low impedance ground path between PCB traces and shielding media. Physically tough, these elas-tomers minimize the risk of gasket damage, in contrast to thin-walled extrusions or unsupported molded gaskets.Silicone-based CHO-SEAL 1310and 1273 materials offer excellent resistance to compression set over a wide temperature range, resulting in years of continuous service. CHO-SEAL 1310 material is filled with silver-plated-glass particles, while 1273 utilizes silver-plated-copper filler to provide higher levels of EMI shielding effectiveness.EMI Spacer GasketsThe unique design of Chomerics’EMI spacer gaskets features a thin plastic retainer frame onto which a conductive elastomer is molded. The elastomer can be located inside or outside the retainer frame, as well as on its top and bottom surface. EMI spacer gaskets provide a newapproach to designing EMI gaskets into handheld electronics such as dig-ital cellular phones. Board-to-board spacing is custom designed to fit broad application needs. Customized cross sections and spacer shapes allow for very low closure forcerequirements and a perfect fit in any design or device.Robotic InstallationSpacer gaskets can be installed quickly by robotic application. Integral locater pins in the plastic spacer help ensure accuratepositioning in both manual and pick-and-place assembly. Benefits include faster assembly and lower labor costs.The integrated conductive elastomer/plastic spacer gasket is a low cost,easily installed system for providing EMI shielding and grounding in small electronic enclosures.Figure 1Single Piece EMI Gasket/Locator PinsCHO-SEAL 1310 or 1273 Conductive Elastomer (Inside)Plastic Spacer Around Outsideor InsideApplications for EMI Spacer GasketsThe spacer gasket concept is especially suited to digital and dual board telephone handsets or other handheld electronic devices. It provides a low impedance path between peripheral ground traces on printed circuit boards and components such as:•the conductive coating on a plastic housing•another printed circuit board •the keypad assemblyTypical applications for EMI spacer gaskets include:•Digital cellular, handyphone and personal communications services (PCS) handsets •PCMCIA cards•Global Positioning Systems (GPS)•Radio receivers•Other handheld electronics, e.g.,personal digital assistants (PDAs)•Replacements for metal EMI shield-ing “fences” on printedcircuit boards in wireless tele-communications devicesstable platform for direct, highprecision molding of conductive elas-tomers. The Vectra A130 material described in Table 1 has excellent heat deflection temperature character-istics (489°F, 254°C). For weight con-siderations, the LCP has aspecific gravity of only 1.61.

你看啊，咱们身边有好多好多电子产品，像手机、平板电脑这些。
这些电子产品里面呢，有很多小小的零件，它们就像一个个小士兵一样，共同努力让这些电子产品能正常工作。
PCB导电泡棉就是这些小零件里很重要的一员哦。
比如说我们的手机，手机里面有一块电路板，这个电路板可复杂啦，上面有好多线路，就像迷宫一样。
这些线路要是不小心碰到一起了，可就乱套了。
这时候PCB导电泡棉就像一个小小的保护神一样。
它可以放在那些容易碰到一起的线路中间，阻止它们乱碰。
我给你们讲个小故事吧。
有一次，我的小表哥他的手机突然出问题了，有些功能不能用了。
他可着急了，就把手机拿到修手机的叔叔那里。
叔叔打开手机一看，原来是里面的电路板上有个小地方出故障了，有些线路总是相互干扰。
叔叔就拿了一小块PCB导电泡棉，放在那两个总是捣乱的线路中间。
就像给它们俩之间建了一堵小墙一样。
然后手机就神奇地好了，小表哥又能开开心心地玩他的游戏啦。
PCB导电泡棉还很柔软呢，就像我们玩的软软的小海绵一样。
它能很好地贴合在电路板上那些弯弯绕绕的地方。
而且啊，它还有导电的本事。
这就很厉害啦，它能让电流按照我们想要的方向走，不会乱跑。
再想象一下，PCB导电泡棉就像一个小小的交通指挥员。
在电路板这个大城市里，电流就像汽车一样跑来跑去。
如果没有交通指挥员，汽车就会乱撞，也就是电流会乱走。
但是有了PCB导电泡棉这个指挥员，电流就能规规矩矩地在自己的道路上行驶啦。
我们在生活中可能看不到PCB导电泡棉，因为它在电子产品的肚子里面呢。
但是它却默默地发挥着很大的作用。
就像那些在幕后默默工作的人一样，虽然我们看不到他们，但是他们的工作对我们来说是非常重要的。
所以呀，下次当你拿着手机玩游戏，或者用平板电脑看动画片的时候，你就可以想象一下，在那个小小的电路板里面，有PCB导电泡棉在努力地工作着，保护着手机和平板电脑的正常运行呢。
