4 Layer ENIG FR4 Sefofu se Patoa Ka PCB
Lifofu Li Patoa Ka PCB
PCB ka vias ka aroloa ka ka tsela, foufetseng ka le patoa ka.Blind burrow PCBs e ka 'na ea e-ba tharollo ha u batla ho beha PTH vias e lekaneng ka boto empa sebaka se lekanyelitsoe.Li-burrows tse foufetseng li sebelisoa ho hokahanya likarolo tsa PCB ka har'a mefokolo ea holim'a metsi.Ho foufala ka tsela ke electroplated ka tsela e hokahanyang lera le le leng feela ka ntle ho karolo e le 'ngoe kapa ho feta tse ka hare.Li-vias tse patoang li na le electroplated vias tse kopanyang likarolo tse peli kapa ho feta tse ka hare empa ha li kopane le lera le ka ntle.
Melemo Ea Lifofu Tse Patoang Ka PCB
1. Meeli ea methapo ea lithapo le liphaephe ka moralo li ka finyelloa ntle le ho eketsa palo ea lihlopha kapa boholo ba boto ea potoloho.
2. Fokotsa karolo karo-karolelano ea PCB potoloho
E foufetse ka/e patoa ka PCB ho kopana le ntlafatso ea boima ba boto ntle le ho eketsa palo ea likarolo kapa boholo ba boto.Ka hona, li-vias tse foufetseng / tse patiloeng li sebelisoa hangata ho HDI PCBs.Hangata e sebelisoa ka mehala ea thekeng, puisano e se nang mohala, MID.Bukana ea ho ngolla.
