《舊聞複習》【通孔印錫膏（PIH，Paste-In-Hole）】製程就是把錫膏(Solder paste)直接印刷於PCB(Print Circuit Board，電路板)的電鍍通孔(PTH, Plating Through Hole)上面，然後再把傳統插件/通孔元件（DIP, Dual In Line Package / THT, Through-Hole Technology）直接插入到已經印有錫膏的電鍍通孔中，這時電鍍通孔上的錫膏會有部分沾粘在插件零件的焊腳上，但大部分還是保留在PCB上，這些沾黏在焊腳以及PCB焊墊上的錫膏在經過回焊爐高溫加熱時會重新熔融，進而將零件焊接於電路板上，可以取代波峰焊接(Wave Soldering)或手焊(Hand Soldering)製程。

錫膏的印刷其實有點像是在牆壁上油漆一般，所不同的，為了要更精確的將錫膏重複塗抹於電路板的一定位置與控制其錫膏量多寡，所以必須要使用一片所謂的「鋼板(stencil)」來控制錫膏的印刷。
Printing the solder paste on the PCB just like painting on the wall. The only different is solder paste printing ask more accurately position and must control the solder paste volume on each pad. It requires a certain jig call “stencil” is a sheet-metal made and have designate aperture on the position that needs to print solder paste.
The operator uses a stencil for solder paste deposition. This is a thin metal plate with openings in it corresponding to pads on the PCB. ... <看更多>
