The latest generation of Texas Instruments (TI) boardmountedpower modules utilizes a pin interconnect technologythat improves surface-mount manufacturability.These modules are produced as a double-sided surfacemount(DSSMT) subassembly, yielding a case-less constructionwith subcomponents located on b ...
表面贴片胶(SMA,surface mount adhesives)用于波峰焊接和回流焊接，以保持组件在印刷电路板(PCB)上的位置，确保在装配线上传送过程中组件不会丢失。PCB装配中使用的大多数表面贴片胶(SMA)都是环氧树脂(epoxies)，虽然还有聚丙烯(acrylics)用于特殊的用途。在高速滴胶系统引入和电子工业掌握如何处理货架寿命相对较短的产品 ...
Calculation of the Differential Impedance of Tracks on FR4 substrates
There is a discrepancy between calculated and measured values of impedance for differential transmission lineson FR4. This is especially noticeable in the case of surface microstrip configurations. The anomaly is shown tobe due to ...
