1. Ci
PCBA substrates thiab cov khoom uas tsis tau siv rau lub sijhawm ntev thiab raug rau huab cua yuav muaj cov dej noo. Ci lawv tom qab ib lub sij hawm los yog ua ntej siv los tiv thaiv ya raws los ntawm kev cuam tshuam PCBA ua.
2. Muab tshuaj txhuam
Solder paste kuj tseem ceeb heev rau kev ua haujlwm ntawm PCBA cov chaw tsim khoom, thiab yog tias muaj cov dej noo hauv cov tshuaj txhuam hniav, nws kuj yog ib qho yooj yim los tsim cov cua qhov los yog cov hlaws dai thiab lwm yam tsis zoo tshwm sim thaum lub sij hawm soldering.
Hauv kev xaiv ntawm solder paste, nws tsis tuaj yeem txiav cov fab. Nws yog ib qho tsim nyog yuav tsum tau siv cov tshuaj txhuam hniav zoo, thiab cov tshuaj txhuam hniav yuav tsum tau ua tiav raws li cov txheej txheem ua kom sov thiab nplawm kom nruj raws li cov txheej txheem ua. Hauv kev ua PCBA thaum ntxov, nws yog qhov zoo tshaj kom tsis txhob nthuav tawm cov tshuaj nplaum rau saum huab cua ntev. Tom qab luam tawm cov tshuaj pleev xim rau hauv cov txheej txheem SMT, nws yog qhov tsim nyog los tuav lub sijhawm rau reflow soldering.
3. Humidity nyob rau hauv lub rhiav
Cov av noo ntawm kev ua haujlwm rhiav kuj yog ib qho tseem ceeb ntawm ib puag ncig zoo rau kev ua PCBA. Feem ntau, nws yog tswj ntawm 40-60%.
4. Rauv kub nkhaus
Ua raws li cov qauv kev cai ntawm cov khoom siv hluav taws xob ua rau lub tshuab hluav taws xob ntsuas qhov kub thiab txias, thiab npaj kom ua kom zoo rau lub qhov cub kub qhov nkhaus. Qhov kub ntawm thaj tsam preheating yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua, kom cov flux tuaj yeem hloov pauv tau, thiab qhov ceev ntawm lub cub tawg tsis tuaj yeem ceev heev.
5. Flux
Nyob rau hauv yoj soldering txheej txheem ntawm PCBA ua, cov flux yuav tsum tsis txhob tsuag ntau dhau.
Fastline Circuitshttp://www.fastlinepcb.com, ib tug qub tub rog electronics ua Hoobkas nyob rau hauv Guangzhou, muaj peev xwm muab koj nrog high-zoo SMT nti ua cov kev pab cuam, nrog rau kev nplua nuj PCBA ua, PCBA cov ntaub ntawv cog lus rau koj los daws koj cov kev txhawj xeeb. Tsiaj Technology tseem tuaj yeem ua DIP plug-in processing thiab PCB ntau lawm, hluav taws xob Circuit Court board tsim ib qho kev pabcuam.
