Kukho iibhodi zeesekethe ezinecala elinye, elinamacala amabini kunye ne-multi-layer.Inani leebhodi ze-multi-layer alikhawulelwanga.Ngoku kukho ngaphezu kwe-100-layer PCBs.IiPCBs eziqhelekileyo ezinomaleko obuninzi zine umaleko kunye neebhodi ezintandathu.Ke kutheni abantu benombuzo othi "Kutheni iibhodi zePCB ezininzi zingamanani alinganayo? Xa sithetha ngokuthelekisekayo, iiPCB ezinamanani alinganayo zineePCB ezingaphaya kwamanani angaqhelekanga, ...

1. Kutheni i-BGA ibekwe kumngxuma wemaski we-solder?Uthini umgangatho wokwamkela?Re: Okokuqala, i solder imaski iplagi umngxuma kukukhusela ubomi benkonzo ye via, kuba umngxuma efunekayo kwisithuba BGA jikelele encinane, phakathi 0.2 kunye 0.35mm.Enye isiraphu akulula ukuba yomiswe okanye ibe ngumphunga, kwaye kulula ukushiya iintsalela.Ukuba imaski yesolder ayiplagi umngxuma okanye iplagi...

1. Ifreyim yangaphandle (icala elibambekayo) lephaneli yeBhodi yeSekethe eShicileleyo kufuneka yamkele uyilo lwe-loop evaliweyo ukuqinisekisa ukuba ijigsaw yePCB ayisayi konakala emva kokulungiswa kwifixture;2. PCB panel ububanzi ≤260mm (SIEMENS umgca) okanye ≤300mm (FUJI line);ukuba ukukhutshwa okuzenzekelayo kuyadingeka, ububanzi bepaneli yePCB × ubude ≤125 mm×180 mm;3. Ubume bejigsaw yePCB kufuneka ibe kufutshane nesikwere kangangoko...
