Litšobotsi tsa sebopeho sa PCB
1. Solderresistant inki (Solderresistant/SolderMask): Ha se libaka tsohle tsa koporo tse lokelang ho ja likaroloana tsa thini, kahoo sebaka se sa jeoang se tla hatisoa ka lera la thepa (hangata epoxy resin) e arolang bokaholimo ba koporo ho tloha ho jeleng thini ho ea ho. qoba ho se solder.Ho na le potoloho e khuts'oane lipakeng tsa mela e entsoeng ka makotikoti.Ho ea ka mekhoa e fapaneng, e arotsoe ka oli e tala, oli e khubelu le oli e putsoa.
2. Dielectric layer (Dielectric): E sebelisetsoa ho boloka ho pata pakeng tsa mela le lihlopha, tse tsejoang e le substrate.
3. Phekolo ea holim'a metsi (SurtaceFinish): Kaha bokaholimo ba koporo bo na le oxidized habonolo tikolohong e akaretsang, e ke ke ea koaheloa ka makotikoti (mafutsana a solderability), kahoo bokaholimo ba koporo bo tla sireletsoa.Mekhoa ea ts'ireletso e kenyelletsa HASL, ENIG, Immersion Silver, Immersion TIn, le organic solder preservative (OSP).Mokhoa o mong le o mong o na le melemo le mefokolo ea oona, ka kakaretso o bitsoa phekolo ea holim'a metsi.

mapolanka rona PCBA li etselitsoe ho kopana le ditlhoko tsena tse ntseng li hōla ka ho fana ka litharollo phahameng-tshebetso kopantseng lebelo, tshebetso, 'me e sebetsang hantle polokelo ya lesedi / phapanyetsano.Hore na o mofani oa litšebeletso tsa komporo ea leru, mohlahlobi e moholo oa data kapa sethala sa litaba tsa sechaba, liboto tsa rona tsa PCBA li u loketse.
Boto ea PCBA e entsoe ka thepa ea boleng bo holimo ea Fr-4 ho netefatsa ho tšoarella le ho ts'epahala.E na le mekhahlelo e 14, e fana ka sebaka se lekaneng bakeng sa likarolo le ho nolofalletsa ho kopanya potoloho e tsoetseng pele.Ka botenya ba 1.6mm, e fihletse ho leka-lekana ho phethahetseng pakeng tsa compactness le tshebetso.
Re utloisisa bohlokoa ba ho nepahala ha computational, ke ka lebaka leo re ralang liboto tsa PCBA tse nang le trace/sebaka bokantle ba 4/4mil.Sena se tiisa phetiso ea mats'oao a boreleli le ho fokotsa kotsi ea tšitiso.ka tekanyo e tlase.Boholo ba ho cheka ba 0.25mm bo netefatsa ts'ebeliso e pharaletseng ea ts'ebeliso, e etsa hore e tšoanele maemo a fapaneng a komporo.
Ho ntlafatsa ts'ebetso le ho sireletsa boto, re sebelisa tente ka mokhoa o thibelang mongobo kapa litšila ho kena PCB.Sena se tiisa ts'epo e kholo le bophelo bo bolelele bakeng sa sistimi ea hau ea komporo.
Ho fana ka khokahanyo e phahameng le ho hanyetsa kutu, liboto tsa rona tsa PCBA li na le pheletso ea ENIG e nang le lesela le lesesaane la khauta holim'a nickel.Sena se etsa hore ho be le khokahanyo e matla le ho ntlafatsa tshebetso ea kakaretso ea boto.
khomphuta rona le peripheral PCBA mapolanka ke tharollo ea ho qetela bakeng sa litlhoko tsa hao komporong.Ka likarolo tsa eona tse tsoetseng pele le boleng ba premium, e tiisa ts'ebetso e tšepahalang le phapanyetsano ea tlhaiso-leseling e potlakileng.Lula u le ka pele ho phetoho ea dijithale ka liboto tsa rona tsa boemo bo holimo tsa PCBA.
