Thaum peb tau txais ib daim ntawm PCB lub rooj tsavxwm thiab tsis muaj lwm yam cuab yeej kuaj ntawm sab, yuav ua li cas thiaj txiav txim siab sai sai rau qhov zoo ntawm lub rooj tsavxwm PCB, peb tuaj yeem xa mus rau 6 cov ntsiab lus hauv qab no:
1. Qhov loj thiab tuab ntawm PCB pawg thawj coj saib yuav tsum ua raws li qhov teev loj thiab tuab yam tsis muaj qhov sib txawv.Yuav tsum tsis muaj qhov tsis xws luag, deformation, poob tawm, khawb, qhib Circuit Court, luv Circuit Court, oxidation dawb, daj, etching tsis huv los yog ntau dhau ntawm etching, thiab yuav tsum tsis muaj stains, tooj liab hais thiab lwm yam impurities ntawm qhov chaw.
2. Ink cover uniform gloss, tsis poob tawm, khawb, dew tooj liab, offset, dai phaj thiab lwm yam tshwm sim.
3. Silkscreen luam ntawv cov cim thiab cov ntawv kom meej, tsis muaj omissions thiab plooj, thim rov qab luam ntawv, offset thiab lwm yam tshwm sim tsis zoo.
4. Cov yeeb yaj kiab carbon yuav tsum tsis muaj qhov tsis xws luag, luam ntawv bias, luv luv Circuit Court, qhib Circuit Court, luam ntawv thiab lwm yam tshwm sim.
5. PCB hauv qab phaj sib sau ua ke, yuav tsum tsis txhob xau, offset, qhov tawg, ntug, ntsaws qhov, npias tawg, npias tshuaj tiv thaiv, crushing thiab lwm yam tshwm sim.
6. Seb lub ntug ntawm PCB board yog du los yog tsis.Yog tias nws yog V-txiav txheej txheem, nws yuav tsum tau them sai sai rau seb qhov V-txiav zawj ua rau cov hlau tawg thiab seb ob tog puas sib haum.
Feem ntau los ntawm 6 cov ntsiab lus no, koj tuaj yeem txiav txim siab sai ntawm PCB pawg thawj coj saib.
