*Game da PCBA*

PCBA ita ce taqaitaccen allon da'irar da aka buga + taro, wato PCBA ita ce dukkan tsarin da ake haɗa sashin sama na allon da aka buga da kuma tsomawa.

NOTE: Dutsen saman da dutsen mutuwa duka hanyoyin haɗa na'urori ne akan allon da'ira da aka buga.Babban bambanci shi ne cewa fasahar hawan dutse ba ta buƙatar ramukan hakowa a cikin kwamitocin da aka buga, ana buƙatar saka fil na ɓangaren a cikin ramukan hakowa na DIP.

Fasahar Dutsen Surface (SMT) Fasahar hawa saman saman tana amfani da na'ura mai ɗaukar hoto da sanya wuri don hawa wasu ƙananan abubuwa akan allon da'ira da aka buga.Its samar tsari hada PCB sakawa, solder manna bugu, jeri inji shigarwa, reflow tanda da masana'antu dubawa.

DIPs sune “plug-ins”, watau saka sassa akan allon da’ira da aka buga.Wadannan sassa suna da girma kuma basu dace da fasahar shigarwa ba kuma an haɗa su a cikin nau'i na plug-ins.Babban hanyoyin samarwa sune: m, toshewa, dubawa, siyarwar igiyar ruwa, goge goge da binciken masana'anta.
