Umugozi wumuringa wa PCB uragwa (nanone bakunze kwita guta umuringa). Inganda za PCB zose zivuga ko arikibazo cya laminate kandi gisaba inganda zibyara umusaruro kwihanganira igihombo kibi.
1. Impapuro z'umuringa zirenze urugero. Umuringa wa electrolytike wumuringa ukoreshwa ku isoko muri rusange usanga uruhande rumwe (rusanzwe ruzwi nka ashing foil) hamwe n’umuringa uruhande rumwe (rusanzwe ruzwi nka foil itukura). Ubusanzwe umuringa wajugunywe ni umuringa usizwe hejuru ya 70um Foil, fayili itukura hamwe n ivu ryivu munsi ya 18um mubyukuri ntabwo byangwa numuringa. Iyo igishushanyo cyumukiriya cyumukiriya cyiza kuruta umurongo wa etching, niba ibisobanuro byumuringa wumuringa byahinduwe ariko ibipimo byo gutondeka ntibihinduka, igihe cyo gutura kumuringa wumuringa mugisubizo cyacyo ni kirekire. Kuberako zinc isanzwe ari icyuma gikora, mugihe insinga zumuringa kuri PCB zishizwe mumuti wigihe kirekire, byanze bikunze bizana kwangirika kuruhande rwumuzunguruko, bigatuma uduce duto duto dusubiza inyuma zinc twakira neza kandi gutandukana na substrate. Ni ukuvuga, insinga z'umuringa zigwa. Ikindi kibazo nuko ntakibazo kijyanye nibipimo bya PCB, ariko nyuma yo gukaraba byogejwe namazi no gukama nabi, insinga z'umuringa nazo zizengurutswe nigisigisigi gisigaye hejuru ya PCB. Niba bidatunganijwe igihe kirekire, bizanatera uruhande rwinshi kuruhande rwumuringa. Fata umuringa. Ibi bintu bikunze kugaragara nko kwibanda kumurongo muto, cyangwa mugihe cyikirere cyinshi, inenge nkiyi izagaragara kuri PCB yose. Andika insinga z'umuringa kugirango urebe ko ibara ryubuso bwitumanaho hamwe nigice fatizo (ibyo bita roughened surface) byahindutse. Ibara ryumuringa uratandukanye numuringa usanzwe wumuringa. Ibara ryumuringa ryumwimerere ryurwego rwo hasi riragaragara, kandi imbaraga zo gukuramo ifu yumuringa kumurongo wijimye nazo zirasanzwe.
2. Kugongana bibaho mugace ka PCB, kandi insinga y'umuringa itandukanijwe na substrate n'imbaraga zo hanze. Iyi mikorere mibi ni imyanya idahwitse cyangwa icyerekezo. Umugozi wumuringa wamanutse uzaba ufite kugoreka cyangwa gushushanya / ibimenyetso byerekana icyerekezo kimwe. Niba ukuyemo insinga z'umuringa mugice gifite inenge ukareba hejuru yubuso bwumuringa wumuringa, urashobora kubona ko ibara ryubuso butagaragara bwumuringa usanzwe, ntihazabaho isuri kuruhande, nimbaraga zishishwa ya feza y'umuringa ni ibisanzwe.
3. Igishushanyo mbonera cya PCB nticyumvikana. Niba ifu yuzuye umuringa ikoreshwa mugushushanya uruziga ruto cyane, bizanatera uburibwe bukabije bwumuzingi no kwangwa n'umuringa.
2. Impamvu zo gutunganya laminate:
Mubihe bisanzwe, mugihe cyose laminate ishyushye gukanda muminota irenga 30, ifiriti yumuringa hamwe na prereg izahuzwa rwose, kubwibyo rero gukanda ntabwo bizagira ingaruka kumubumbe wumuringa wumuringa hamwe na substrate muri laminate. . Ariko rero, murwego rwo gutondekanya no gutondekanya laminates, niba PP yaranduye cyangwa ifu yumuringa yangiritse, imbaraga zo guhuza hagati yumuringa wumuringa na substrate nyuma yo kumurika nazo ntizihagije, bikavamo guhagarara (kubisahani binini gusa) Amagambo ) cyangwa insinga z'umuringa rimwe na rimwe zigwa, ariko imbaraga zishishwa zumuringa wumuringa hafi yinsinga zizimye ntizisanzwe.
3. Impamvu zitera laminate ibikoresho fatizo:
1. Nkuko byavuzwe haruguru, amashanyarazi asanzwe ya electrolytike yumuringa nibicuruzwa byose byashizwe hejuru cyangwa bikozwe mu muringa. Niba impinga idasanzwe mugihe cyo gukora ifu yubwoya, cyangwa mugihe cyo gusya / gusya umuringa, amashami ya kirisiti ya kristu ni mabi, bigatuma umuringa wumuringa ubwawo Imbaraga zo gukuramo ntizihagije. Iyo impapuro mbi zometseho impapuro zakozwe muri PCB no gucomeka mu ruganda rwa elegitoroniki, insinga z'umuringa zizagwa kubera ingaruka ziva hanze. Ubu bwoko bwo kwanga umuringa ntibuzatera kwangirika kuruhande nyuma yo gutobora umugozi wumuringa kugirango ubone ubuso bukabije bwumuringa wumuringa (ni ukuvuga ubuso bwo guhuza na substrate), ariko imbaraga zishishwa zumuringa wose zizaba zikennye .
2. Guhuza n'imikorere mibi yumuringa wumuringa na resin: laminates zimwe zifite ibintu byihariye, nkimpapuro za HTg, zikoreshwa ubu kubera sisitemu zitandukanye. Umuti ukiza ukoreshwa muri rusange PN resin, kandi imiterere ya marinike ya molekile iroroshye. Urwego rwo guhuza ni ruto, kandi birakenewe gukoresha ifu yumuringa hamwe nimpinga idasanzwe kugirango ihuze. Iyo utanga laminates, ikoreshwa ryumuringa ntirihuye na sisitemu ya resin, bikavamo imbaraga zidahagije zo gukuramo impapuro zometseho icyuma, hamwe ninsinga z'umuringa zidasesekaye mugihe winjizamo.
