Ukongeza, ubukhulu bebhodi iyonke buyanda kakhulu xa ubhedu olunzima lukwimaleya amaninzi, nto leyo enokuchaphazela iinkqubo zokuvelisa ezifana nokubhola kunye nokufaka imingxuma edlulayo.
Ngaba iiPCB zekopolo ezinzima zingasetyenziswa ngeteknoloji yokuxhoma umphezulu (SMT)?
Ewe, ii-PCB zekopolo enzima zinokuyilwa kwiinxalenye ze-SMT. Nangona kunjalo, kufuneka kuqwalaselwe ngokukodwa ukusetyenziswa kwe-solder paste, ukubekwa kweenxalenye, kunye neeprofayili zokuphinda ziphume ngenxa yobunzima obuphezulu bobushushu beeleya zekopolo ezinzima. Iinxalenye ze-SMT ezifinyeziweyo zinokufuna ubukhulu bekopolo obuqhelekileyo kwiindawo zazo zokuxhoma.
Yintoni ethathwa njenge "copper enzima" kwimveliso yePCB?
Ngokubanzi, naluphi na ubukhulu bobhedu obungaphezulu kwe-3 oz (105 µm) buthathwa njengobhedu olunzima. Nangona kunjalo, inkcazo inokwahluka ngokuxhomekeke kwisicelo kunye nomzi-mveliso. Abanye abavelisi banokujonga i-3 oz njengendawo yokuqala yobhedu olunzima, ngelixa abanye banokubeka umda kwi-4 oz okanye ngaphezulu.
Ixabiso leePCB zekopolo ezinzima lithelekiswa njani neePCB eziqhelekileyo?
IiPCB zekopolo enzima zihlala zibiza kakhulu kuneePCB eziqhelekileyo ngenxa yezinto ezininzi: Iindleko zokwanda kwezinto eziluhlaza (ikopolo engaphezulu) Amaxesha okucubungula amade, ingakumbi ekukroleni Izixhobo zigugile kakhulu ngexesha lokwenziwa Iinkqubo zokuvelisa ezintsonkothileyo Imveliso enokuba sezantsi ngenxa yokunyamezelana kokwenziwa Nangona kunjalo, iindleko ezonyukileyo zinokuncitshiswa kukuphucula ukusebenza, ukuthembeka, kunye nokukwazi ukunciphisa inani leeleya kwezinye uyilo.
Ukhetha njani ubukhulu be-PCB copper?
Ngokweendlela ezahlukeneyo zokusetyenziswa kwePCB, ubukhulu bobhedu obufunekayo buyahluka. Njengee-PCB zeemveliso zabathengi kunye nonxibelelwano ngokubanzi, ubukhulu bobhedu obuyi-0.5oz, 1oz, kunye ne-2oz buyafuneka; kwiimveliso ze-elektroniki ezithwala amandla aphezulu, njengeemveliso ze-voltage ephezulu, iibhodi zombane, kunye nezinye iimveliso, ii-PCB ngokubanzi zifuna ubhedu olungaphezulu kwe-3oz. Ngamafutshane, khetha ubukhulu bobhedu obufanelekileyo ngokweemfuno zemveliso.
Zingaphi iileya zobhedu ezikwi-PCB?
Kukho umaleko omnye wobhedu kwi-PCB enecala elinye. Kukho iileya ezimbini zobhedu kwi-PCB enecala elinye. Kukho iileya ezingaphezu kwezibini zobhedu kwi-PCB eneeleya ezininzi. Umzekelo, kukho iileya ezine zobhedu kwi-PCB eneeleya ezine.
Ngaba kukho umahluko phakathi kwebhodi yesekethe yobhedu olunzima kunye neePCB zobhedu olunzima?
Akukho mahluko phakathi kwala magama mabini, onke athetha iibhodi zesekethe eziprintiweyo ezinobukhulu be-3oz okanye ubhedu obukhulu. Iibhodi ze-PCB zobhedu obukhulu okanye ubhedu obunzima zisetyenziswa kakhulu kwiibhodi ze-elektroniki ezinamandla aphezulu.
Yintoni ubunzima bobhedu obuqhelekileyo kwii-PCB zeCopper eziNzima?
Ubunzima bobhedu obuqhelekileyo kwiiPCB zobhedu ezinzima bungaphezulu kwee-ounces ezi-2 (70um). Kodwa singavelisa nobukhulu bobhedu obuphezulu njengePCB yobhedu eyi-4 oz, iPCB yobhedu eyi-10 oz kunye nePCB yobhedu efikelela kwi-20 oz.
Zeziphi izinto ezisetyenziswa kwi-Heavy Copper PCBs?
Ubhedu lwe-RTF kufuneka lusetyenziswe.
Izinto zokuzalisa ezingcono kwi-lamination
Ii-substrates eziphezulu zokuqhuba ubushushu
Ngaba kukho naziphi na izinto ekufuneka ziqwalaselwe xa usebenza ngee-PCB ze-Heavy Copper?
