BGA teihana whakapiringa whakataki
Teihana whakapiri BGAe kiia ana hoki ko te teihana rework BGA, he taputapu motuhake e whakamahia ana ki nga maramara BGA me nga raru o te whakapiri, ka hiahia ranei kia whakakapihia nga maramara BGA hou.Mai i te mea he tiketike te whakaritenga pāmahana o te maramara maramara BGA, na reira kaore e taea e te taputapu whakamahana whanui te whakatutuki i ona hiahia.
Kei te mahi te tepu whakapiri BGA me te paerewarerere umupihi, no reira he tino whai hua ki te mahi ano i te BGA, a ka eke te reiti angitu ki te neke atu i te 98% mena ka mahia me te tepu whakapiri BGA pai ake.
Te whakarōpūtanga o te tepu rework BGA
1. Tauira a-ringa
A, no te whakanohoia BGA i runga i PCB, whakawhirinaki te reira i runga i te wheako o te kaiwhakahaere ki te whakapiri i te reira rite ki te anga tā mata i runga i PCB, i te mea e tika ana mo BGA maramara reworking ki BGA solder pōro ware nui (i runga 0.6).Hāunga te ānau pāmahana i te wa e whakahaerehia aunoatia ana te whakawera, me mahi ā-ringa katoa ētahi atu mahi.
2. tauira Semi-aunoa
He iti rawa te papa tine poipoi BGA (0.15-0.6) Ko nga maramara BGA ka haere a ringa ki te papaki ka he, ka ngawari te kino o te whakapiri.Ko te maataapono tiaroaro orotika ko te whakamahi i te punaha atahanga prism spectroscopic ki te whakanui i nga hononga solder BGA me nga papa PCB, kia īnaki ai o raatau whakaahua i muri i te papaki poutū, ka karo i nga hapa ka puta i roto i te papaki.Ka rere aunoa te punaha whakamahana i muri i te otinga o te papaki, a ka puta he whakaoho whakaoho i muri i te mutunga o te whakapiri.
3. Tauira aunoa
Ko te tikanga o te ingoa, ko tenei tauira he punaha mahi ano aunoa, e ahu mai ana i runga i te whakahiato tirohanga miihini o tenei tikanga hangarau-nui ki te whakatutuki i te mahi whakahou aunoa.
