8 Layer Impedance ENIG PCB

Ka mor'a hore PCB e etsoe ka lesoba la halofo, lera la thini le behiloe moeling oa lesoba ka electroplating.Lera la thini le sebelisoa e le lera le sireletsang ho matlafatsa khanyetso ea ho lla le ho thibela ka ho feletseng hore lera la koporo le theohe leboteng la lesoba.Ka hona, moloko oa litšila ts'ebetsong ea tlhahiso ea boto ea potoloho e hatisitsoeng e fokotsehile, 'me mosebetsi oa ho hloekisa o boetse o fokotsehile, e le ho ntlafatsa boleng ba PCB e phethiloeng.

Ka mor'a hore tlhahiso ea PCB e tloaelehileng ea halofo e phethoe, ho tla ba le litsupa tsa koporo mahlakoreng ka bobeli a halofo ea lesoba, 'me litsupa tsa koporo li tla ameha ka lehlakoreng le ka hare la lesoba la halofo.Half lesoba e sebelisoa e le ngoana PCB, karolo ea halofo ea lesoba ke tshebetsong ea PCBA, e tla nka halofo ea ngoana oa PCB, ka ho fana ka halofo ea lesoba ho tlatsa thini ho etsa halofo ea mong'a poleiti welded ka boto ka sehloohong. , 'me halofo ea lesoba le sekotoana koporo, tla ka ho toba ama thini, ama tjheseletsa ka tieo ea lakane ka motherboard, le ama ponahalo le tšebeliso ea tshebetso eohle mochine.

Bokaholimo ba lesoba la halofo bo fanoa ka lera la tšepe, 'me mateano a halofo ea lesoba le moeli oa' mele o fanoa ka lekhalo, 'me holim'a lekhalo ke sefofane kapa holim'a lekhalo. motsoako wa sefofane le bokahodimo ba sebaka.Ka ho eketsa lekhalo lipheletsong tse peli tsa lesoba la halofo, litsupa tsa koporo mateanong a halofo ea lesoba le lehlakoreng la 'mele lia tlosoa ho theha PCB e boreleli, ka katleho ho qoba litsupa tsa koporo tse setseng ka har'a lesoba, ho netefatsa boleng ba sekoti. PCB , hammoho le tjheseletsa e ka tšeptjoang le ponahalo boleng ba PCB tshebetsong ea PCBA, le ho etsa bonnete ba tshebetso ya mochine kaofela ka mor'a kopano e latelang.
