PCB davhlau ya nyob twg thaiv cov kev thaiv lub davhlau ya nyob twg siv rau kev sib txuas hluav taws xob ntawmluam tawm cov board, uas yog cov khoom siv hluav taws xob siv los ua kom tiav kev sib txuas hluav taws xob. Tus qauv pcb yam tsis muaj ib qho khoom sib xyaw nyob rau sab saum toj yog feem ntau hu ua "pwb".
Yuav ua li cas thiaj li xaiv cov xaim hluav taws xob? Nco ntsoov cov ntsiab lus no peb:
1. Pom: Tus tsim nyog wiring terminals tsis tau pom hloov tag nrho, nrog lub ntsej muag du thiab tsis muaj khawb. Lub ntsaws thiab pin (socket) muaj qib siab ntawm kev sib koom tes.
2. Cov khoom siv: ua ntej, xaim thav duab yuav tsum tau disassembled rau kev kuaj ntxiv. Thib ob, cov khoom yas yuav tsum muaj nplaim taws zoo.
3. Torque yog qhov tseem ceeb heev rau cov ntsia hlau torque ntawm lub davhlau ya nyob twg. Nws yog qhov zoo tshaj plaws los siv cov ntsia hlau ntsia hlau kom hnov seb cov ntsia hlau nias lub hlau nruj me ntsis thaum xaiv.
Cov hauv paus ntsiab lus ntawm kev xaiv:
1. Txiav txim siab seb hom davhlau ya nyob twg koj xav tau
2. Qhov loj ntawm xaim
3. Tam sim no
4. Qhov loj ntawm qhov chaw siv
Txoj kev qhia zoo rau PCB Wiring Terminals:
1. Cov tsos txawv txawv: lub davhlau ya dav hlau muaj ib lossis ntau tus hlau tuag {}} reting xov ntawm cov xov xwm, uas yog cov xov hlau tawm tsam
2. Nyhav sib txawv: tooj yog hnyav dua zinc nyob rau hauv lub davhlau ya nyob twg
3. Xim qhov sib txawv: Tom qab txheej plating rau saum npoo ntawm lub davhlau ya nyob twg yog txiav qhib, tus xim daj uas zoo li tooj liab, thiab cov xim dawb yog zinc.
