Lub Hom Phiaj 1.

Standardize cov PCB txheej txheem tsim cov khoom lag luam, hais qhia qhov tsis sib xws ntawm PCB txheej txheem tsim, ua PCB tsim raws li qhov xav tau ntawm kev tsim khoom, ntsuas tau, nyab xeeb, EMC, EMI thiab lwm yam kev qhia tshwj xeeb, thiab tsim kom muaj qhov zoo ntawm cov txheej txheem, thev naus laus zis, zoo thiab raug nqi ntawm cov khoom nyob rau hauv tus txheej txheem ntawm cov khoom tsim.

Kev tshuaj xyuas cov teeb meem cuam tshuam ntawm PCB txheej txheem tsim

2. Daim ntawv thov dav

Cov lus qhia tshwj xeeb no siv rau PCB txheej txheem tsim ntawm txhua yam khoom siv hluav taws xob, thiab siv rau tab sis tsis txwv rau PCB tsim, PCB pawg thawj coj pov thawj txheej txheem tshuaj xyuas, saib xyuas txheej txheem txheej txheem ib leeg thiab lwm yam dej num. Yog tias muaj kev tsis sib haum xeeb ntawm cov txheej txheem cuam tshuam thiab cov ntsiab lus tshwj xeeb ua ntej Txoj Cai no thiab cov cai ntawm Txoj Cai no, txoj cai no yuav tsum yeej.

3. Txhais kom meej

Los ntawm lub qhov (VIA): Lub qhov hlau uas siv rau kev sib txuas sab hauv, tab sis tsis yog rau kev ntxig cov khoom sib txuas lossis lwm yam khoom siv txhawb nqa.

Qhov muag tsis pom ntawm: Qhov hla dhau ntawm daim ntawv luam tawm mus rau tsuas yog ib sab.

Faus los ntawm: Lub qhov hluav taws xob uas tsis txuas mus rau saum npoo ntawm cov ntawv luam tawm.

Los ntawm kev hla: Ib qhov hla los ntawm ib sab ntawm cov ntawv luam tawm mus rau lwm qhov.

Cheebtsam qhov: qhov siv rau ntu ntu txuas rau PCB thiab kev sib txuas hluav taws xob ntawm cov duab hluav taws xob.

Sawv ntsug: Ntsug nrug los ntawm hauv qab ntawm lub cev ntawm cov cuab yeej saum npoo mus rau hauv qab ntawm tus pin.

5. Tswj cov ntsiab lus

5.1 PCB pawg thawj coj xav tau

5.1.1 Txiav txim siab PCB phaj thiab TG tus nqi

Txiav txim xyuas lub rooj tsav xwm siv rau PCB, xws li FR – 4, txhuas, ceramic, ntawv tub ntxhais, thiab lwm yam. Yog tias siv TG siab, tuab tuab yuav tsum tau qhia hauv daim ntawv.

5.1.2 Txiav txim siab txheej txheej txheej txheej ntawm PCB

Txiav txim siab PCB tooj liab txheej txheej txheej txheej txheej, xws li tin, npib tsib xee kub lossis OSP, thiab sau tseg hauv daim ntawv.
