I-FAQ eqhelekileyo

Zeziphi izinto eziluncedo ngee-MCPCBs?

I-MCPCBs ineenzuzo ezininzi kwii-PCB eziqhelekileyo, kubandakanywa ukuchithwa kobushushu obungcono, ukuphuculwa kozinzo lwe-thermal, kunye nokwandisa amandla omatshini. Bakwakwazi ukuxhasa imithwalo yangoku ephezulu kwaye babonelele ngcono kwaye bakhusele ekuphazamisekeni kwe-electromagnetic.
Luluphi uqwalaselo loyilo lweePCB zeceramic?

Ukuyila i-PCB ye-ceramic kufuna ingqalelo ekhethekileyo ngenxa yeempawu ezizodwa zezinto ze-ceramic. Ukwandiswa kwe-Thermal coefficients, amandla oomatshini, kunye nesidingo se-ceramic vias zonke ziyimiba ebalulekileyo yoyilo ekufuneka iqwalaselwe. Kubalulekile ukusebenza nomvelisi onamava onobuchule kuyilo lwe-ceramic PCB kunye nemveliso ukuqinisekisa iziphumo ezilungileyo.
Zeziphi izinto ezisetyenziselwa ukwenza iiPCB zeceramic?

IiPCB zeCeramic ziqhele ukwenziwa kwi-alumina (Al2O3) okanye i-aluminiyam nitride (AlN) iiseramikhi. I-Alumina iqhele ukusetyenziswa kwi-thermal conductivity ephezulu kunye neempawu zokugquma umbane, ngelixa i-AlN iyaziwa ngokugqithiswa kwayo kwe-thermal kunye nokufakelwa kombane ophezulu.
Ndingaqinisekisa njani umgangatho wePCBA yam?

Ukuqinisekisa umgangatho we-PCBA yakho, kubalulekile ukusebenza kunye nomvelisi othembekileyo nonamava olandela iinkqubo ezingqongqo zolawulo lomgangatho. Ukongeza, ukwenza uvavanyo olucokisekileyo kunye nokuhlolwa kwemveliso egqityiweyo kunokunceda ukuchonga nayiphi na imiba okanye iziphene.
Yintoni umahluko phakathi kwePCBA kunye nePCB?

PCB ibhekisa kwibhodi ebonakalayo equlathe ukudityaniswa kweesekethe kunye nombane, ngelixa i-PCBA ibhekisa kwimveliso egqityiweyo emva kokuba amacandelo e-elektroniki afakwe kwi-PCB.
Zeziphi iindidi zamacandelo ezinokusetyenziswa kwi-PCBA?

Kukho uluhlu olubanzi lwamacandelo anokuthi asetyenziswe kwi-PCBA, kubandakanywa izixhobo zokunyuka komhlaba (SMDs), amacandelo e-hole, iisekethe ezidibeneyo (ICs), i-resistors, i-capacitors, kunye nabanye abaninzi.
Buthini ubomi bePCB?

Ubomi bePCB buxhomekeke kwizinto ezahlukeneyo, kubandakanywa umgangatho wamacandelo asetyenziswayo, iimeko zokusingqongileyo apho i-PCB isetyenziswa khona, kunye nobungakanani boxinzelelo olubekwe ebhodini. Nangona kunjalo, ngoyilo olufanelekileyo kunye nokuveliswa, i-PCB inokuhlala iminyaka eliqela.
Yintoni inkqubo yokwenziwa kwePCB?

Inkqubo yokwenziwa kwePCB ibandakanya ukuyila iskimu sesekethe, ukuyila uyilo lwesekethe, ukuprinta uyilo ebhodini, ukudibanisa iindlela zobhedu ebhodini, imingxuma yokugrumba yamacandelo, kunye nokuncamathisela amacandelo ebhodini. Ibhodi ke iye ivavanywe ukuqinisekisa ukuba isebenza njengoko bekucetyiwe.
Ziziphi iingenelo zokusebenzisa iPCB?

PCBs zinika inani leenzuzo ngaphezu kwezinye iindlela zokudala iisekethe zombane, kubandakanywa ubungakanani obuncitshisiweyo kunye nobunzima, ukuthembeka okwandisiweyo, kunye nokukhululeka kokuhlanganisa kunye nokuveliswa kobuninzi. Ukongeza, ii-PCBs zinokuyilwa ukuba zibandakanye iisekethe ezintsonkothileyo kwaye zinokuthatha uluhlu olubanzi lwamacandelo.
Zeziphi izinto eziqhelekileyo zokugqiba umphezulu?

Ngesicelo esahlukileyo, sinokwenza ukugqiba komphezulu okwahlukileyo ukuhlangabezana nabathengi. Uluhlu lokugqitywa komphezulu, ukuba i-Best Technology Co, Limited inamandla okwenza ulwazi lwakho. I-HAL PCB:umgangatho womoya oshushu (HAL), osebenzisa i-Sn ukwenza ukugqiba umphezulu, funda ngakumbi... OSP PCB:Organic solderability preservative (OSP),funda ngakumbi... ENIG PCB:Electroless Nickel/Immersion Gold (ENIG), Ukuntywiliselwa kwegolide kwiipads, funda ngakumbi ... ENEPIG PCB: nickel engenambane ye-electroless palladium igolide yokuntywiliselwa (ENEPIG),funda mor
