Hais txog PCB peb paub zoo, PCB tseem hu ua Circuit Boards, Circuit Court boards, hardware engineers inevitably yuav tsum tau ua si ob peb pawg.Tab sis hais txog SMT, PCBA, tab sis ob peb tus neeg nkag siab txog dab tsi tshwm sim, thiab txawm tias feem ntau tsis meej pem cov ntsiab lus no.
Niaj hnub no los tham txog, PCB, PCBA, SMT, qhov sib txawv ntawm qhov twg, thiab qhov txuas yog dab tsi?
Lub npe yog cov ntawv luam tawm Circuit Board, tseem hu ua cov ntawv luam tawm Circuit Board (cov ntawv luv ntawm Printed Circuit Board), yog siv los txhawb nqa cov khoom siv hluav taws xob thiab muab cov kab kom ua tiav Circuit Court tsim ntawm cov khoom siv hluav taws xob.
SMT yog cov ntawv luv ntawm Surface Mounted Technology, cov txheej txheem nrov tshaj plaws rau kev txuas cov khoom siv hluav taws xob ntawm PCB boards los ntawm ib txheej txheem, tseem hu ua nto mount technology.
Nws yog hais txog cov txheej txheem ua haujlwm (cov ntawv luv rau Printed Circuit Board Assembly) uas yog ib lub khw muag khoom rau cov khoom siv raw khoom, SMT qhov chaw, DIP insertion, kuaj, thiab tiav cov khoom sib dhos.
Yog "PCB yog ib lub rooj tsavxwm, SMT yog ib lub tshuab, PCBA yog cov txheej txheem / cov khoom tiav", nyob rau hauv qhov khoob PCB, SMT qhov chaw (los yog DIP plug-in), cov khoom tiav tuaj yeem hu ua PCBA, lossis cov txheej txheem tuaj yeem hu ua PCBA.
Thaum peb disassemble cov khoom siv hluav taws xob, koj tuaj yeem pom lub rooj tsav xwm Circuit Court yog soldered tag nrho ntawm cov khoom, lub rooj tsavxwm yog PCBA ua ntawm PCB.
