Gukora tekinoroji ya kimwe cya kabiri cyumwobo PCB
Umwobo wacuzwe igice cyaciwemo kabiri nyuma yumwobo uzengurutse. Biroroshye kugaragara ibintu bisigara byumuringa wumuringa hamwe nu ruhu rwumuringa kurigata mu mwobo wigice, bigira ingaruka kumikorere yumwobo wigice kandi bigatuma igabanuka ryibicuruzwa n'umusaruro. Kugirango tuneshe inenge zavuzwe haruguru, bizakorwa hakurikijwe inzira zikurikira za metallised semi-orifice PCB
1. Gutunganya igice cyumwobo kabiri V icyuma.
2. Mu myitozo ya kabiri, umwobo uyobora wongeyeho ku nkombe y’umwobo, uruhu rwumuringa rukurwaho mbere, kandi burr iragabanuka. Amashanyarazi akoreshwa mugucukura kugirango yongere umuvuduko wo kugwa.
3. Isahani y'umuringa kuri substrate, ku buryo igice cy'umuringa gishyizwe ku rukuta rw'umwobo rw'umwobo uzengurutse ku nkombe y'isahani.
4. Umuzenguruko wo hanze ukorwa na firime yo guhonyora, kwerekana no guteza imbere substrate nayo, hanyuma substrate igashyirwaho umuringa na tin inshuro ebyiri, kuburyo umuringa wumuringa kurukuta rwumwobo wurwobo ruzengurutse kuruhande rwa isahani irabyimbye kandi umuringa utwikiriwe na tin layer hamwe n'ingaruka zo kurwanya ruswa;
5. Igice cya kabiri kigize isahani impande zombi zizengurutswe mo kabiri kugirango zibe igice;
6. Gukuraho firime bizakuraho firime anti-plating ikanda mugikorwa cyo gukanda film;
7. Kuramo substrate, hanyuma ukureho umuringa ugaragara hejuru yumurongo winyuma wa substrate nyuma yo gukuraho firime;
Amabati yo gukuramo amabati Substrate irashishwa kugirango amabati akurwe kurukuta rwacitsemo kabiri hanyuma umuringa kurukuta rwacitsemo kabiri.
8. Nyuma yo kubumba, koresha kaseti itukura kugirango uhuze ibyapa hamwe, no hejuru yumurongo wa alkaline kugirango ukureho burrs
9. Nyuma yumuringa wa kabiri wumuringa hamwe namabati yometse kuri substrate, umwobo uzenguruka kumpande yisahani ucibwamo kabiri kugirango ube umwobo. Kuberako umuringa wurukuta rwumwobo utwikiriwe na tin layer, kandi umuringa wumuringa wurukuta rwumwobo uhujwe rwose nu muringa wumuringa wurwego rwinyuma rwa substrate, kandi imbaraga zihuza ni nini, umuringa ku mwobo urukuta rushobora kwirindwa neza mugihe cyo gutema, nko gukuramo cyangwa ibintu byo gufata umuringa;
10. Nyuma yo kurangiza igice cy-umwobo hanyuma ugakuraho firime, hanyuma etch, okiside yumuringa ntishobora kubaho, wirinde neza ko habaho ibisigisigi byumuringa ndetse nibintu bigufi byumuzunguruko, bizamura umusaruro wibyuma bya PCB byacuzwe.
