PCBA Cov qauv tsim qauv yuav tsum mus los ntawm peb theem: Tsim qauv, kev tsim khoom, thiab kuaj. Cov kauj ruam tshwj xeeb yog raws li hauv qab no:
1. Tsim theem: Ua tiav cov duab kos duab thiab ERC cov txheej txheem, xws li cov txheej txheem pcb (xws li cov txheej txheem 2\/4), thiab xyuas kom meej kab yog sib npaug thiab cuam tshuam.
2. Kev tsim kho kom tsim nyog:Txheeb xyuas cov ncoo loj thiab sib xyaw ua ke (xws li SMT ntau dua lossis sib npaug ntawm DFM, cov chaw kuaj cov khoom lag luam, cov chaw yuav khoom (ua ntej lub sijhawm luv luv).
3. Kev tsim khoom thiab sib dhos:
PCB pawg thawj coj ua: xa cov ntaub ntawv Gerber thiab tshawb xyuas cov thawj daim (xws li kev xeem yuam kev);
SMT PATH: Ua kom zoo rau tus hlau Mesh cov roj ntsha, tsom rau kev saib xyuas cov cheebtsam xws li BGA;
Nthuav Soldering: Ua tiav los ntawm kev sib dhos los ntawm tes lossis yoj soldering.
4. Kuaj thiab Debugging:
Kev ntsuas theem (voltage, WaveForm) TCT pom tus nqi thiab kev ntsuas luv luv → kev sim siab (kub \/ voltage hloov pauv).
5. Kev ua kom zoo dua:Tshawb xyuas cov teeb meem (cov khoom siv txias sib xyaw
