Lera impedance ENIG PCB 6351

Mora PCB entsoe ka lesoba halofo, lera thini e beha ka bohale ba lesoba ke electroplating. Lera la thini le sebelisoa e le lera le sireletsang ho tiisa ho taboha ha meokho le ho thibela lera la koporo ka botlalo ho oela leboteng la lesoba. Ka hona, moloko oa ho se hloeke tšebetsong ea tlhahiso ea boto ea potoloho e hatisitsoeng e fokotsehile, mme mosebetsi oa ho hloekisa le ona oa fokotseha, e le ho ntlafatsa boleng ba PCB e felileng.

Kamora hore tlhahiso ea PCB e tloaelehileng ea mokoti e phethoe, ho tla ba le likhalase tsa koporo mahlakore ka bobeli a halofo ea lesoba, 'me likhalase tsa koporo li tla nka karolo lehlakoreng le kahare la halofo ea lesoba. Halofo lesoba e sebediswa e le ngoana PCB, karolo ea halofo lesoba e ka tshebetso ya ho PCBA, tla nka halofo ea ngoana oa PCB, ka ho fana ka halofo lesoba tlatsa thini ho etsa halofo ea master poleiti welded ka boto ka sehloohong , 'me halofo ea lesoba e nang le likhechana tsa koporo, e tla ama thini ka kotloloho, e amang ho tjheseletsa ka thata ho lakane ho board ea mama, mme e ame ponahalo le ts'ebeliso ea ts'ebetso eohle ea mochini.

Bokaholimo ba sekoti bo fanoa ka mokato oa tšepe, 'me mateano a halofo ea lesoba le bohale ba' mele ka ho latellana a fuoa lekhalo, 'me bokaholimo ba lekhalo ke sefofane kapa bokaholimo ba lekhalo ke motswako wa sefofane le bokaholimo ba bokahodimo. Ka ho eketsa lekhalo lipheletsong ka bobeli tsa lesoba la halofo, likhalase tsa koporo mateanong a halofo ea lesoba le bohale ba 'mele lia tlosoa ho theha PCB e boreleli, ka mokhoa o atlehileng o qoba likhase tsa koporo tse setseng mokoti oa halofo, ho netefatsa boleng ba PCB, hammoho le ts'ehetso e tšepahalang le boleng ba ponahalo ea PCB nakong ea PCBA, le ho netefatsa ts'ebetso ea mochini kaofela kamora kopano e latelang.
