PCB (printed circuit board) yog ib lub printed circuit board, uas yog ib qho tseem ceeb ntawm kev lag luam hluav taws xob. Txij li cov moos me me thiab cov tshuab xam zauv mus rau cov khoos phis tawj loj, cov khoom siv sib txuas lus hluav taws xob, thiab cov riam phom tub rog, tsuav yog muaj cov khoom siv hluav taws xob xws li cov voj voog sib xyaw, txhawm rau ua kom muaj kev sib txuas hluav taws xob ntawm ntau yam khoom, lawv yuav siv PCB.
Yog li yuav ua li cas los tshuaj xyuas PCB nrog lub tshuab ntsuas qhov muag?
1. Xyuas seb qhov chaw ntawm PCB puas puas tsuaj.
Yuav kom tsis txhob muaj luv luv Circuit Court, nws qhov hauv qab, cov kab, cov qhov thiab lwm qhov yuav tsum tsis muaj kab nrib pleb thiab khawb.
2. Xyuas seb qhov chaw PCB puas khoov
Yog tias qhov nkhaus ntawm qhov chaw tshaj qhov deb, nws raug suav hais tias yog cov khoom tsis zoo
3. Xyuas seb puas muaj cov tin slag ntawm ntug ntawm PCB
Qhov ntev ntawm cov tin slag ntawm ntug ntawm PCB board tshaj 1MM, uas suav hais tias yog cov khoom tsis zoo
4. Xyuas seb qhov chaw vuam puas zoo
Tom qab txoj kab vuam tsis txuas ruaj khov lossis qhov chaw notch tshaj 1/4 ntawm qhov chaw vuam, nws raug suav hais tias yog cov khoom tsis zoo.
5. Xyuas seb puas muaj qhov yuam kev, qhov tsis suav lossis qhov tsis meej pem hauv kev luam ntawv ntawm cov ntawv nyeem ntawm qhov chaw.
