1. Lub chaw ua haujlwm yuav tsum ceev kom huv thiab huv si hauv thaj chaw ua haujlwm PCBA. Tsis muaj khoom noj lossis dej haus yuav tsum muab khaws cia. Tus kheej cov khoom tsis cuam tshuam rau kev ua haujlwm yog nruj me ntsis txwv. Kev haus luam yeeb yog nruj me ntsis txwv.
2. Tsis txhob coj cov solered saum npoo nrog txhais tes liab qab hauv PCBA nti ua, vim tias cov roj hauv soldenability ntawm cov kev tshwm sim ntawm soldering tsis xws luag.
3. Cov txheej txheem kev ua haujlwm ntawm PCBA ua thiab cov khoom siv yuav tsum yooj yim li sai tau los tiv thaiv cov kauj ruam uas tsis ua yuam kev. Cov hnab looj tes ua ke yuav tsum tau siv. Vim cov hnab looj tes qias neeg yuav ua rau muaj kuab paug, hnab looj tes tshiab yuav tsum tau hloov ntau yog tias tsim nyog.
4. Tsis txhob siv roj teeb los tiv thaiv cov tawv nqaij lossis ntau zaus tshuaj ntxuav uas muaj cov silicone, uas tuaj yeem ua rau muaj teeb meem hauv solderability. Npaj ua tshuaj ntxuav kom zoo rau PCBA vuam nto yog muaj.
5. Electrostatic Rhiab cov khoom yuav tsum tau cim nrog cov cim tsim nyog los tiv thaiv kom tsis txhob muaj lwm yam. Tsis tas li ntawd, txhawm rau tiv thaiv hluav taws xob zoo li qub los ntawm kev siv hluav taws xob tseem ceeb, txhua txoj haujlwm, kev sib dhos thiab kev sib dhos thiab kev sib dhos yuav tsum tau ua tiav ntawm cov hluav taws xob ua haujlwm.
6. Tshawb xyuas cov kev tawm tsam zoo li qub tsis tu ncua kom paub meej tias lawv tuaj yeem ua haujlwm ib txwm (tawm tsam zoo li qub). Ntau yam kev phom sij ntawm cov hluav taws xob hluav taws xob tuaj yeem tshwm sim los ntawm kev sib txuas hauv av, yuav tsum tau muab rau cov pob qij txha sib txuas ntawm "kab thib 3.
7. Nws yog txwv kom muaj pawg PCBA Circuit Court, uas yuav ua rau lub cev puas. Cov cim tshwj xeeb tshwj xeeb yuav tsum tau muab rau ntawm qhov chaw ua haujlwm kom muab cov pob zeb PCBA Circuit Court raws lawv hom.
Nyob rau hauv kev ua pcba thaj ua rau thaj, cov kev cai ua hauj lwm no yuav tsum tau ua nruj me ntsis thiab ua haujlwm tau zoo, txo qis kev puas tsuaj ntawm cov khoom thiab txo tus nqi.
