Ponena za PCB zomwe timazidziwa bwino, PCB imatchedwanso matabwa ozungulira, matabwa ozungulira, akatswiri a hardware ayenera kusewera matabwa angapo.Koma tchulani SMT, PCBA, koma ndi anthu ochepa omwe amamvetsetsa zomwe zikuchitika, ndipo nthawi zambiri amasokoneza malingalirowa.
Lero kuti tikambirane, PCB, PCBA, SMT, pali kusiyana kotani pakati, ndi maulalo otani?
Dzinali ndi bolodi losindikizidwa, lomwe limadziwikanso kuti bolodi losindikizidwa (chidule cha Printed Circuit Board), limagwiritsidwa ntchito kuthandizira chonyamulira cha zigawo zamagetsi ndikupereka mizere kuti dera lonse lipangidwe pakati pa zigawo zamagetsi.
SMT ndiye chidule cha Surface Mounted Technology, ukadaulo wodziwika bwino woyika zida zamagetsi pama board a PCB kudzera munjira imodzi, yomwe imadziwikanso kuti ukadaulo wapamtunda.
Zimatanthawuza njira yokonza (chidule cha Printed Circuit Board Assembly) yomwe ndi malo amodzi ogulira zinthu zopangira, kuyika kwa SMT, kuyika kwa DIP, kuyesa, ndi kusonkhanitsa zomaliza.
Kodi "PCB ndi bolodi, SMT ndi ukadaulo, PCBA ndi njira / yomalizidwa", mu PCB yopanda kanthu, kuyika kwa SMT (kapena pulagi ya DIP), chomaliza chingatchedwe PCBA, kapena njirayo ingatchulidwe. PCBA.
Pamene ife disassemble mankhwala amagetsi, mukhoza kuona bolodi dera ndi soldered wodzaza zigawo zikuluzikulu, bolodi ndiye PCBA processing wa PCB.
