Ibintu byamabati mabi kuri PCB na gahunda yo gukumira

Ikibaho cyumuzunguruko kizerekana amabati mabi mugihe cyo gukora SMT. Mubisanzwe, gutobora nabi bifitanye isano nisuku yubuso bwa PCB bwambaye ubusa. Niba nta mwanda uhari, mubyukuri ntihazabaho amabati mabi. Icya kabiri, gutobora Iyo flux ubwayo ari mbi, ubushyuhe nibindi. Nibihe bintu nyamukuru byerekana inenge zamashanyarazi zisanzwe mumashanyarazi no gutunganya? Nigute wakemura iki kibazo nyuma yo kugitanga?
1. Amabati yubuso bwa substrate cyangwa ibice bya okiside kandi ubuso bwumuringa bwijimye.
2. Hano hari flake hejuru yurubaho rwumuzunguruko rudafite amabati, kandi isahani yo hejuru hejuru yikibaho ifite umwanda.
3. Igikoresho kinini gishobora gutwikirwa kirakomeye, hariho ikintu cyaka, kandi hariho uduce hejuru yurubaho nta mabati.
4. Ubuso bwibibaho byumuzunguruko bifatanye namavuta, umwanda nizindi sundries, cyangwa hari amavuta ya silicone asigaye.
5. Hano hari impande zigaragara neza kumpande zumwobo ushobora kuba muto, kandi hejuru-ishobora gutwikirwa irakaze kandi irashya.
6. Igipfundikizo kuruhande rumwe cyuzuye, kandi igipfundikizo kurundi ruhande kirakennye, kandi hari impande zigaragara kumpera yumwobo muto ushobora kuba.
7. Ubuyobozi bwa PCB ntabwo bwijejwe guhura nubushyuhe cyangwa igihe mugihe cyo kugurisha, cyangwa flux ntabwo ikoreshwa neza.
8. Hariho umwanda uhumanye mubisahani hejuru yikibaho cyumuzunguruko, cyangwa gusya ibice bisigara hejuru yumuzunguruko mugihe cyo gukora substrate.
9. Agace kanini gafite ubushobozi buke ntigashobora gushyirwaho amabati, kandi hejuru yikibaho cyumuzunguruko gifite ibara ryijimye ryijimye cyangwa umutuku utukura, ufite igifuniko cyuzuye kuruhande rumwe naho urundi ruhande.
