Yintoni i  -PCB yobhedu olunzima?

Iimveliso zePCB zobhedu olunzima zisetyenziswa kakhulu kwizixhobo zombane zombane kunye nenkqubo yonikezelo lwamandla.Ubuninzi bePCB yobhedu eyongezelelweyo yenza ukuba ibhodi iqhube umsinga ophezulu, ukuphumeza ukusasazwa kakuhle kwe-thermal kunye nokuphumeza iiswitshi eziyinkimbinkimbi kwindawo encinci.

Olu hlobo lukhethekileyo lwePCB yobhedu olushinyeneyo lunobunzima bobhedu obugqityiweyo obungaphezulu kwee-ounces ezi-4 (i-140 microns), xa kuthelekiswa nobukhulu bobhedu obuqhelekileyo bePCB ye-1ozor 2oz.

Ngesiqhelo, ubukhulu bobhedu be-PCB eqhelekileyo yi-1oz ukuya kwi-3oz. IiPCB ezishinyeneyo zobhedu okanye ii-PCB zobhedu ezinzima ziintlobo ze-PCBs ukuba ubunzima bobhedu obugqityiweyo bungaphezulu kwe-4oz (140μm). I-PCB etyebileyo yobhedu yeyodidi olukhethekileyo lwePCB. izinto zayo zokuqhuba, izinto ze-substrate, inkqubo yokuvelisa, imimandla yesicelo yahlukile kwii-PCB eziqhelekileyo. Ukucakwa 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. I-PCB yobhedu etyebileyo isetyenziswa ngokubanzi kwizixhobo zasekhaya ezahlukeneyo, iimveliso zobugcisa obuphezulu, ezomkhosi, ezonyango kunye nezinye izixhobo zombane. Ukusetyenziswa kwe-PCB yobhedu engqindilili yenza icandelo eliphambili lemveliso yezixhobo zombane-iibhodi zesekethe zinobomi obude benkonzo, kwaye kwangaxeshanye luncedo kakhulu ekunciphiseni ubungakanani bezixhobo zombane.

Kwiprototype ye-PCB, i-PCB yobhedu engqindilili yeyeteknoloji ekhethekileyo, inemida ethile yobugcisa kunye nobunzima bokusebenza, kwaye iyabiza. Okwangoku, kwinkqubo yeprototype ye-PCB, i-YMS inokufikelela kwi-1-30 umaleko, ubukhulu becala lobhedu yi-13oz, ubuncinci bobungakanani bomngxuma yi-0.15 ~ 0.3mm.

Kunye nokwanda kweemveliso ezinamandla aphezulu, imfuno yeePCBs ezityebileyo zobhedu yonyuka 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. Kwangaxeshanye, iibhodi ezinkulu zangoku zinokuphucula ukuyilwa kwenkululeko yocingo, ngaloo ndlela iqonda ukuba i-miniaturization yeyo yonke imveliso.Ngamafutshane, i-PCB yesekethe etyebileyo yobhedu idlala indima engenakuphinda ithathelwe indawo kwizicelo ezinamandla amakhulu, angoku aphezulu, kwaye imfuno yokupholisa ephezulu. Inkqubo yokwenziwa kunye nezixhobo zePCBS ezinobhedu olunzima zineemfuno eziphezulu kakhulu kuneePCB eziqhelekileyo. Ngezixhobo eziphucukileyo kunye neenjineli eziqeqeshiweyo, i-China YMS PCB ngumvelisi oqeqeshiweyo onokubonelela ngeePCB zobhedu ezityebileyo ezinomgangatho ophezulu kubathengi abasuka ekhaya nakumazwe aphesheya.
