A. Ibintu bitunganya uruganda PCB

1. Kurenza urugero rwumuringa

Umuringa wa electrolytike wumuringa ukoreshwa ku isoko muri rusange usanga uruhande rumwe (rusanzwe ruzwi nka ashing foil) hamwe no gushiraho umuringa uruhande rumwe (bakunze kwita file itukura). Umuringa usanzwe wumuringa usanzwe ushyizwe hejuru yumuringa hejuru ya 70um, umutuku utukura na 18um. Ifu yo gukaraba ikurikira ntabwo ahanini yanze umuringa. Iyo igishushanyo cyumuzunguruko cyiza kuruta umurongo wa etching, niba umuringa wumuringa uhindagurika ariko ibipimo byo gutembera ntibihinduka, ibi bizatuma ifu yumuringa iguma mubisubizo birebire cyane.

Kuberako zinc isanzwe ari icyuma gikora, mugihe insinga z'umuringa kuri PCB zashizwe mumuti wigihe kirekire, bizatera kwangirika kuruhande rwumurongo, bigatuma umurongo unanutse ushyigikira urwego rwa zinc rwakirwa rwose kandi rutandukanijwe substrate, ni ukuvuga, insinga y'umuringa iragwa.

Ikindi kibazo nuko ntakibazo kijyanye nibipimo bya PCB, ariko gukaraba no gukama ntabwo ari byiza nyuma yo gutobora, bigatuma insinga z'umuringa zizengurutswe nigisubizo gisigaye gisigaye hejuru ya PCB. Niba bidatunganijwe igihe kirekire, bizanatera uruziga rukabije rwumuringa kuruhande no kwangwa. umuringa.

Ibi bintu byibanda kumurongo muto, cyangwa mugihe ikirere kimeze neza, inenge zisa zizagaragara kuri PCB yose. Andika insinga z'umuringa kugirango urebe ko ibara ryubuso bwaryo hamwe nigice cyibanze (ibyo bita roughened surface) byahindutse, bitandukanye numuringa usanzwe. Ibara rya file riratandukanye. Ibyo ubona ni ibara ryumwimerere ryumuringa wurwego rwo hasi, kandi imbaraga zishishwa zumuringa wumuringa kumurongo wijimye nazo zirasanzwe.

2. Isanganya ryaho ryabaye mubikorwa bya PCB, kandi insinga z'umuringa zatandukanijwe na substrate n'imbaraga zo hanze zikoreshwa.

Iyi mikorere mibi ifite ikibazo cyo guhagarara, kandi insinga z'umuringa biragaragara ko zizunguruka, cyangwa gushushanya cyangwa ibimenyetso byerekana icyerekezo kimwe. Kuramo umugozi wumuringa mugice gifite inenge hanyuma urebe hejuru yubuso bwumuringa wumuringa, urashobora kubona ko ibara ryubuso butagaragara bwumuringa usanzwe, ntihazabaho kwangirika kuruhande, hamwe nimbaraga zo gukuramo umuringa wumuringa ni ibisanzwe.

3. Igishushanyo mbonera cya PCB kidafite ishingiro

Gushushanya imiyoboro yoroheje hamwe na fayili y'umuringa mwinshi bizanatera uburibwe bukabije bwumuzunguruko no guta umuringa.

B.Impamvu yuburyo bwa laminate

Mubihe bisanzwe, ifiriti yumuringa hamwe na prereg bizahuzwa rwose mugihe cyose igice cyo hejuru cyubushyuhe bwa laminate gishyushye kanda muminota irenga 30, kubwibyo rero gukanda ntabwo bizagira ingaruka kumubano wumuringa wumuringa na substrate muri laminate. Ariko, murwego rwo gutondekanya no gutondekanya laminate, niba PP yanduye cyangwa umuringa wangiritse wumuringa wangiritse, bizanatuma habaho imbaraga zidahuza hagati yumuringa wumuringa na substrate nyuma yo kumurika, bikavamo gutandukana kumwanya (gusa kubisahani binini)) Cyangwa rimwe na rimwe insinga z'umuringa ziragwa, ariko imbaraga zishishwa zumuringa hafi yumurongo ntisanzwe.

C. Impamvu zitera laminate ibikoresho fatizo:
1. Nkuko byavuzwe haruguru, impapuro zisanzwe z'umuringa wa electrolytike ni ibicuruzwa byose byashizwe hejuru cyangwa bikozwe mu muringa kuri ubwoya bw'ubwoya. Niba agaciro ntarengwa k'ubwoya bw'ubwoya budasanzwe mugihe cyo kubyara, cyangwa mugihe cyo gusya / gusya umuringa, amashami ya kirisiti ya kristu ni mabi, bigatuma ifu yumuringa ubwayo Imbaraga zo gukuramo ntizihagije. Nyuma yuko impapuro mbi zometseho impapuro zakozwe muri PCB, insinga z'umuringa zizagwa kubera ingaruka zingufu zituruka hanze iyo icomekwa mu ruganda rwa elegitoroniki. Ubu bwoko bwo kwanga umuringa ntibushobora kugira ruswa igaragara mugihe cyo gutobora umugozi wumuringa kugirango ubone ubuso bukabije bwumuringa wumuringa (ni ukuvuga ubuso bwo guhuza na substrate), ariko imbaraga zishishwa zumuringa wose uzaba umuringa uzaba cyane abakene.

2 Urwego rwo guhuza ni ruto, kandi birakenewe gukoresha ifu yumuringa hamwe nimpinga idasanzwe kugirango ihuze. Umuringa wumuringa ukoreshwa mugukora laminates ntabwo uhuye na sisitemu ya resin, bigatuma imbaraga zidahagije zishishwa zicyuma cyometseho icyuma, hamwe ninsinga mbi z'umuringa zimeneka mugihe winjizamo.
