Ngesiqhelo, ubukhulu bobhedu be-PCB eqhelekileyo yi-1oz ukuya kwi-3oz. PCBs Thick-zobhedu okanye PCBs ezinzima-zobhedu iintlobo PCBs ukuba ubunzima ubhedu egqityiweyo ngaphezu 4oz (140μm) .Ikopolo eshinyeneyo ivumela enkulu PCB-umnqamlezo-amacandelo imithwalo eliphezulu yangoku kwaye ikhuthaza ukuchithwa ubushushu. Uyilo oluqhelekileyo luyi-multilayer okanye ngamacala amabini. Ngobu buchwephesha bePCB kukwanokwenzeka ukudibanisa izakhiwo ezicokisekileyo zoyilo kumaleko angaphandle kunye namaleko obhedu angqindilili kumaleko angaphakathi.
I-PCB etyebileyo yobhedu yeyodidi olukhethekileyo lwePCB. izinto zayo conductive, izinto substrate, inkqubo yokuvelisa, amasimi isicelo zahlukile PCBs eqhelekileyo. Ukubekwa kweesekethe zobhedu ezishinyeneyo kuvumela abavelisi bePCB ukuba bonyuse ubunzima bobhedu ngeendonga ezisecaleni kunye nemingxunya egcweleyo, enokunciphisa amanani umaleko kunye neenyawo. I-Thick-copper plating idibanisa i-high-current and control circuits, ukwenza ukuxinana okuphezulu kunye nezakhiwo zebhodi ezilula kunokufezekiswa.
Ukwakhiwa kweesekethe ezinzima zobhedu zinika ii-PCB ezi
zinzuzo
2.Ukunyamezela okuphezulu kwiintlobo ze-thermal
3.Ukutshatyalaliswa kobushushu
obungcono 4.Ukwandisa amandla omatshini kwizixhumi kunye nemingxuma ye-PTH
5.Nciphisa ubungakanani bemveliso
Ukusetyenziswa kweePCBs ezityebileyo zobhedu
Kunye nokukhula kweemveliso zamandla aphezulu, imfuno yeePCBs ezityebileyo zobhedu yanda kakhulu. Abavelisi be-PCB banamhlanje banikela ingqalelo ngakumbi ekusebenziseni ibhodi yobhedu eshinyeneyo ukusombulula ukusebenza kakuhle kwe-thermal ye-elektroniki yamandla aphezulu.
I-PCBs ezityebileyo zobhedu ubukhulu becala zinkulu zangoku, kwaye iiPCBs ezinkulu zangoku zisetyenziswa ikakhulu kwimodyuli yamandla kunye neendawo zombane zemoto. Iimoto zemveli, unikezelo lwamandla, kunye nosetyenziso lwezixhobo zombane zombane zisebenzisa iindlela zokuqala zothumelo ezifana nokuhanjiswa kwentambo kunye neshiti lentsimbi. Ngoku iibhodi ezityebileyo zobhedu zithatha indawo yefom yokuhanjiswa, engakwazi nje ukuphucula imveliso kunye nokunciphisa iindleko zexesha locingo, kodwa ukwandisa ukuthembeka kweemveliso zokugqibela. Ngexesha elifanayo, iibhodi ezinkulu zangoku zinokuphucula inkululeko yoyilo lwe-wiring, ngaloo ndlela iqonda i-miniaturization yemveliso yonke.
Isekethe ye-PCB etyebileyo yobhedu idlala indima engenakuthathelwa indawo kwizicelo ezinamandla amakhulu, angoku aphezulu, kunye nemfuno ephezulu yokupholisa. Inkqubo yokuvelisa kunye nezixhobo ze-PCBS ezinobhedu ezinzima zineemfuno eziphezulu kakhulu kunee-PCB eziqhelekileyo. Ngezixhobo eziphucukileyo kunye neenjineli ezichwepheshile, i-YMS ibonelela ngeePCB ezityebileyo zobhedu ezinomgangatho ophezulu kubathengi abasuka ekhaya nakwamanye amazwe.
