PCB halofo-soba boto e bua ka ea bobeli ho cheka le sebopeho tshebetso ka mor'a hore lesoba la pele e phunngoa, 'me qetellong halofo ea lesoba metallized e boloketsoe.Sepheo ke ho tjheseletsa ka ho toba moeli oa lesoba ho ea moeling o ka sehloohong ho boloka lihokelo le sebaka, 'me hangata li hlaha lipotolohong tsa matšoao.
Hangata mapolanka a potoloho a halofo ea lesoba a sebelisoa bakeng sa ho kenya lisebelisoa tsa elektronike tse matla haholo, tse kang lisebelisoa tsa cellular, lioache tse bohlale, lisebelisoa tsa bongaka, lisebelisoa tsa molumo le tsa video, joalo-joalo Li thusa ho fokotsa sekhahla sa potoloho le mekhoa e mengata ea ho hokahanya, ho etsa hore lisebelisoa tsa elektronike li be nyenyane, li be bobebe. mme e sebetsa hantle ho feta.
Sekoti se sengata se sekoti lipheletsong tsa PCB ke e 'ngoe ea lintho tse sebelisoang hangata molemong oa tlhahiso ea PCB,' me mosebetsi oa eona o ka sehloohong ke ho lokisa PCB.Ts'ebetsong ea tlhahiso ea boto ea PCB, ka ho siea likoti tse halofo maemong a itseng moeling oa boto ea PCB, boto ea PCB e ka ts'oaroa ka sesebelisoa kapa ntlo e nang le likurufu.Ka nako e ts'oanang, nakong ea ts'ebetso ea kopano ea boto ea PCB, lesoba la halofo le boetse le thusa ho beha le ho hokahanya boto ea PCB ho netefatsa ho nepahala le botsitso ba sehlahisoa sa ho qetela.
Sekoti sa halofo se kenngoeng ka lehlakoreng la boto ea potoloho ke ho ntlafatsa ts'episo ea khokahanyo ea lehlakore la boto.Hangata, ka mor'a hore boto ea potoloho e hatisitsoeng (PCB) e fokotsoe, lesela le pepesitsoeng la koporo moeling le tla pepesoa, le atisang ho ba le oxidation le corrosion.E le ho rarolla bothata bona, lera koporo hangata tlotsitsoe ka lera sireletsang ka electroplating bohale ba boto ka lesoba halofo ho ntlafatsa khanyetso lona oxidation le ho hanyetsa kutu, 'me e ka boela eketsa sebaka tjheseletsa le ho ntlafatsa ho tšepahala ha oxidation. kgokelo.
Nakong ea ts'ebetso, mokhoa oa ho laola boleng ba sehlahisoa ka mor'a ho etsa masoba a semi-metallized moeling oa boto, joalo ka meutloa ea koporo leboteng la lesoba, joalo-joalo, esale e le bothata bo boima ts'ebetsong ea ts'ebetso.Bakeng sa mofuta ona oa boto e nang le mokoloko o feletseng oa likoti tse entsoeng ka semi-metallized The PCB board e tšoauoa ka bophara bo batlang bo le bonyenyane ba lesoba, 'me e sebelisoa haholo bakeng sa boto ea morali oa boto ea' mè.Ka masoba ana, e cheselitsoe hammoho le boto ea 'mè le lithakhisa tsa likarolo.Ha ho soasoa, ho tla lebisa ho solder e fokolang, ho soasoa ka bohata, le potoloho e khuts'oane ea borokho lipakeng tsa likhoele tse peli.
