PCBA sib dhos zoo tswj
(1) Kev xaiv ntawm magnification rau magnification pab ntaus ntawv
Raws li ib qho ntawm txoj hauv kev yooj yim tshaj plaws los ua cov kev kuaj xyuas phau ntawv, cov neeg soj ntsuam feem ntau yuav tsum tau siv ntau yam cuab yeej magnifying kom pom cov khoom sib txuas thiab ntau yam ntxiv. Qhia meej txog qhov kev nthuav dav uas yuav tsum tau ua kom nthuav dav cov cuab yeej pabcuam (cov iav tsom iav, tsom iav, thiab lwm yam) thiab tsim kom muaj qee qhov kev nthuav dav dav raws li kev kuaj xyuas PCBA ncoo dav thiab lwm yam muaj. Qhov laj thawj tseem ceeb rau cov lus qhia no yog kom tsis txhob muaj kev sim ntau dhau los ntawm kev nthuav dav ntau dhau.
(2) Kev tshuaj xyuas cov tshuaj nplaum
Solder paste luam ntawv yog cov txheej txheem tseem ceeb hauv SMT kev tso kawm ntawm PCBA cov rooj sib txoos. Solder paste luam ntawv yog txheej txheem nyuaj uas yuav tsum tau ua kom zoo thiab ua tiav cov txheej txheem saib xyuas cov txheej txheem thiab tswj cov txheej txheem. Yam tsawg kawg yog manually xyuas cov cheeb tsam thiab ntsuas lub thickness, tab sis nws yog qhov zoo tshaj plaws los siv cov kev pab cuam tsis siv neeg, thickness, thiab ntim ntsuas. Cov khoom siv tshuaj xyuas cov tshuaj pleev xim muaj xws li ib qho yooj yim 3X magnifier, solder paste thickness gauge siv kho qhov muag lossis laser thickness ntsuas, thiab ib qho kim automated online solder paste tester.
Txhawm rau kom tswj tau qhov zoo ntawm SMT sib dhos welds, muaj ntau qhov teeb meem tshwm sim thaum lub sij hawm luam ntawv los tiv thaiv kev sib dhos tsis zoo los ntawm kev nkag mus rau cov kauj ruam tom ntej ntawm SMT qhov chaw.
(3) Kev tshuaj ntsuam xyuas
Dot loj kuj tseem ceeb rau thaj kho. Raws li nrog solder paste luam ntawv, ua kom cov txheej txheem nyob rau hauv kev tswj yuav tsum tau ib tug zoo-txhais thiab zoo-ua raws cov txheej txheem saib xyuas zoo. Nws raug nquahu kom siv phau ntawv tshuaj xyuas ntawm qhov chaw nplaum.
(4) Kev tshuaj xyuas kev sib koom ua ke
Qhov zoo ntawm cov pob qij txha yog lub hauv paus rau kev ntseeg siab ntawm PCBA cov khoom. Cov pob qij txha yuav tsum tau soj ntsuam tas li thiab soj ntsuam xyuas cov vuam thiab kev kuaj pom kom ua tau raws li qhov yuav tsum tau ua. X-ray tshuaj xyuas AXI yog cov cuab yeej zoo tshaj plaws rau kev tswj thiab kho cov txheej txheem ntawm yoj soldering thiab reflow soldering.
