Dab tsi yog qhov tsis xws luag hauv PCBA ua
1. Luv Circuit Court
Hais txog qhov tshwm sim ntawm kev koom nrog ntawm ob qho kev ywj pheej nyob ib sab txuas txuas tom qab siv tas. Qhov ua rau yog tias cov pob qij txha txuas tau ze dhau, cov ntu tau teeb tsa tsis raug, qhov kev taw qhia tsis raug, qhov siv qhov nrawm nrawm dhau, txheej txheej txheej tsis txaus, thiab tsis muaj qhov tsis zoo ntawm qhov chaw, cov kua nplaum tsis zoo, cov tshuaj txhuam ntau dhau , lwm yam
2. Vuam vuam
Tsis muaj cov tin nyob rau hauv cov trench tin, thiab cov khoom thiab cov substrate tsis txuas nrog ua ke. Qhov laj thawj rau qhov xwm txheej no yog qhov tsis zoo vuam vias, qhov taw siab, qhov muag tsis zoo ntawm qhov chaw, qhov seem tsis zoo, kev faib khoom tsis raug, thiab cov kua nplaum ntau dhau hauv cov vuam trench. Thawj chav kawm yuav ua rau vuam khoob. PAD qhov chaw ntawm qhov tsis siv vuam feem ntau yog ci thiab du.
3. Vuam cuav
Muaj cov tin nyob nruab nrab ntawm ko taw ntawm ib feem thiab qhov txuas vuam, tab sis nws yeej tsis ua tiav los ntawm cov tin. Feem ntau ntawm qhov laj thawj yog tias rosin muaj nyob hauv cov pob qij txha txuas los yog tshwm sim los ntawm nws.
4. Vuam txias
Kuj tseem hu ua cov tin uas tsis tau daws, nws yog tshwm sim los ntawm qhov tsis txaus txaus soldering kub los yog luv luv txaus lub sij hawm soldering. Qhov ua tsis tau zoo tuaj yeem txhim kho los ntawm kev siv cov khoom siv thib ob. Qhov saum npoo ntawm cov tshuaj txhuam cov tshuaj txhuam hauv qhov sib tov txias yog tsaus thiab feem ntau yog hmoov.
5. Qhov seem poob
Tom qab kev ua haujlwm soldering, cov khoom tsis nyob hauv txoj haujlwm raug. Qhov laj thawj rau qhov no yog xaiv cov kua nplaum tsis raug lossis ua haujlwm tsis raug kua nplaum tsis zoo, ua tsis tiav ntawm cov khoom siv kua nplaum, ntau dhau cov yoj yoj thiab qeeb qeeb siv lub tshuab ua kom nrawm, thiab lwm yam.
6. Qhov seem
Qhov uas yuav tsum tau teeb tsa tab sis tsis tau teeb tsa.
7. Puas
Cov tsos ntawm qhov pom tau pom tseeb, cov khoom tsis xws luag, lossis cov txheej txheem ua los, lossis cov khoom tawg thaum lub sijhawm txheej txheem txheej txheem. Tsis txaus preheating ntawm qhov chaw thiab substrates, nrawm heev txias tom qab soldering, thiab lwm yam.
8. Kev tsis lees paub
Qhov tshwm sim no feem ntau tshwm sim ntawm qhov tsis txaus. Nws yog tshwm sim los ntawm kev kho plating tsis zoo ntawm lub davhlau ya nyob twg ntawm ib feem. Yog li ntawd, thaum dhau los ntawm cov yoj yoj, txheej plating melts rau hauv cov phuam da dej, ua rau cov qauv ntawm lub davhlau ya nyob twg puas tsuaj, thiab cov laug tsis ua raws. Zoo, thiab kub dua thiab lub sijhawm siv sij hawm ntev dua yuav ua rau qhov tsis zoo loj dua. Ib qho ntxiv, qhov dav dav vuam ntsuas kub qis dua vuam vuam, tab sis lub sijhawm ntev dua. Yog li ntawd, yog tias cov khoom tsis zoo, feem ntau nws yuav ua rau yaig.
