Ikibaho cyumuzunguruko wa PCB mubikorwa byumusaruro, akenshi gihura ninenge zimwe na zimwe, nka PCB yumuzunguruko wumuzunguruko wumuringa wumuringa nabi (nanone bakunze kuvuga ko bajugunya umuringa), bigira ingaruka kumiterere yibicuruzwa. Impamvu zisanzwe zituma ikibaho cyumuzunguruko wa PCB zitera umuringa nizi zikurikira:

PCB yumuzunguruko wibikorwa
1, umuringa wo gufunga umuringa urakabije, icyuma cya electrolytike cyumuringa gikoreshwa kumasoko muri rusange ni uruhande rumwe (rusanzwe ruzwi nka gray foil) hamwe numuringa ushyizwe kumurongo umwe (bakunze kwita foil itukura), umuringa usanzwe muri rusange urenga 70um umuringa wumuringa, umutuku utukura na 18um munsi yumwanda w ivu ntiwabaye icyiciro cyumuringa.
2. Kugongana kwaho bibaho mubikorwa bya PCB, kandi insinga z'umuringa zitandukanijwe na substrate n'imbaraga zo hanze. Iyi nenge igaragara nkimyanya idahwitse cyangwa icyerekezo, kugwa umuringa wumuringa bizagira kugoreka kugaragara, cyangwa muburyo bumwe bwikimenyetso / ingaruka. Kuramo igice kibi cyumuringa kugirango ubone hejuru yumuringa wumuringa, urashobora kubona ibara risanzwe ryumuringa wumuringa, ntihazabaho isuri mbi, imbaraga zumuringa zumuringa nibisanzwe.
3, igishushanyo mbonera cya PCB ntabwo gishyize mu gaciro, hamwe nigishushanyo cyumuringa cyumuringa cyumurongo muto cyane, bizanatera umurongo urenze urugero hamwe numuringa.
Kuraho impamvu
Mubihe bisanzwe, mugihe cyose ubushyuhe bushyushye hejuru yubushyuhe bwa laminate muminota irenga 30, ifiriti yumuringa hamwe nurupapuro rwakize igice cyahujwe rwose, bityo rero gukanda muri rusange ntabwo bizagira ingaruka kumpuza zumuringa na substrate muri laminate. Ariko, murwego rwo gutondekanya no gutondekanya laminate, niba umwanda wa PP cyangwa umwanda wumuringa wangiritse, bizanatuma habaho imbaraga zidahuza hagati yumuringa wumuringa na substrate nyuma ya laminate, bikavamo guhagarara (gusa kubisahani binini) cyangwa insinga z'umuringa rimwe na rimwe igihombo, ariko imbaraga zo kwambura umuringa wumuringa hafi yumurongo wo kwambura ntizisanzwe.

Laminate impamvu yibanze
1, amashanyarazi asanzwe ya electrolytike yumuringa ni ibicuruzwa cyangwa bikozwe mu muringa, niba agaciro k’umusaruro w’ubwoya bw’ubwoya budasanzwe, cyangwa gusya / gusya umuringa, gutwikira dendritic mbi, bikavamo ifiriti y'umuringa ubwayo gukuramo imbaraga ntibihagije, ifi mbi ikanda ikanda ikozwe muri PCB icomeka mu ruganda rwa elegitoroniki, insinga z'umuringa zizagwa kubera ingaruka zituruka hanze. Ubu bwoko bubi bwo kwambura umuringa insinga z'umuringa hejuru (ni ukuvuga guhuza ubuso na substrate) nyuma yisuri igaragara, ariko ubuso bwose bwumuringa wo gukuramo umuringa uzaba muke.
2 gukiza, kugirango ukoreshe impinga idasanzwe y'umuringa hamwe na match. Iyo umusaruro wa laminate ukoresheje umuringa wumuringa hamwe na sisitemu ya resin idahuye, bikavamo amabati yicyuma cyo gukuramo imbaraga ntabwo bihagije, gucomeka nabyo bizagaragara kumeneka nabi wumuringa.

Byongeye kandi, birashoboka ko gusudira bidakwiye mubakiriya biganisha ku gutakaza pade yo gusudira (cyane cyane panele imwe na kabiri, imbaho ​​nyinshi zifite ahantu hanini hasi, ubushyuhe bwihuse, ubushyuhe bwo gusudira buri hejuru, ntabwo byoroshye cyane kugwa):
Gusubiramo inshuro nyinshi gusudira ikibanza;
Temperature Ubushyuhe bwo hejuru bwo kugurisha ibyuma biroroshye gusudira padi;
Pressure Umuvuduko mwinshi ushyirwaho nicyuma cyo kugurisha umutwe kuri padi kandi igihe kinini cyo gusudira kizasiba padi.
