8 Inzitizi zibangamira ENIG PCB 6351

PCB imaze gukorwa mu mwobo wa kimwe cya kabiri, amabati ashyirwa ku nkombe y’umwobo ukoresheje amashanyarazi. Amabati akoreshwa nk'urwego rwo gukingira kugira ngo arwanye amarira kandi arinde rwose umuringa ugwa ku rukuta rw'umwobo. Kubwibyo, ibisekuruza byanduye mubikorwa byo gutunganya ikibaho cyumuzingo cyacapwe kiragabanuka, kandi akazi ko gukora isuku nako kagabanuka, kugirango ubuziranenge bwa PCB burangire.

Nyuma yo kubyara igice gisanzwe cya PCB kirangiye, hazaba imiringa yumuringa kumpande zombi zumwobo, kandi imiringa yumuringa izagira uruhare muruhande rwimbere rwumwobo. Igice cya kabiri cyakoreshejwe nkumwana PCB, uruhare rwigice cya kabiri kiri mubikorwa bya PCBA, bizafata igice cyumwana wa PCB, mugutanga igice cyumwobo wuzuye amabati kugirango igice cya plaque nkuru gisudwe ku kibaho kinini , na kimwe cya kabiri cyumwobo hamwe nibisigazwa byumuringa, bizagira ingaruka kumabati, bigira ingaruka kumasuderi neza kurupapuro kurububiko, kandi bigira ingaruka kumiterere no gukoresha imikorere yimashini yose.

Ubuso bwigice cyumwobo butangwa nicyuma, kandi ihuriro ryigice cyakabiri nu mpande zumubiri bitangwa hamwe nu cyuho, naho ubuso bwicyuho ni indege cyangwa ubuso bwicyuho ni a guhuza indege n'ubuso bwubuso. Mugukomeza icyuho kumpande zombi zumwobo, imitwe yumuringa ihurira yumwobo wigice nigice cyumubiri ikurwaho kugirango ikore PCB yoroshye, wirinde neza ibyuma byumuringa bisigaye mumwobo wigice, byemeza ubuziranenge bwa PCB, kimwe no gusudira kwizewe no kugaragara neza kwa PCB mugikorwa cya PCBA, no kwemeza imikorere yimashini yose nyuma yo guterana nyuma.
