PCB kubwebweta ndi vuto lomwe limafala pa ma wave soldering. Chodabwitsa chachikulu ndikuti mawanga kapena ziphuphu zimawonekera pamwamba pa PCB, zomwe zimapangitsa PCB kuyala. Ndiye zomwe zimayambitsa matuza a PCB munjira yowotchera mafunde ndi chiyani? Kodi kuthetsa vuto la PCB kubwebweta?

Zomwe zimayambitsa kuphulika kwa PCB:

1. Kutentha kwa malata ndikokwera kwambiri

Zomwe zimayambitsa matuza a PCB munjira yowotchera mafunde ndi momwe angawathetsere

2. Kutentha kwa preheating ndikwambiri

3. Kuthamanga kwa lamba wofalitsa ndikuchedwa kwambiri

4. Bokosi la PCB kudzera mu ng’anjo yamatini nthawi zambiri

5. PCB board yadetsedwa

6. Zinthu za PCB ndizolakwika

7. Pad ndi yayikulu kwambiri

8. PCB mkati m’njira zosiyanasiyana

9. Kuwala kwa UV sikoyenera

10. Kuchuluka kwa mafuta obiriwira sikukwanira

11. Malo osungira a PCB anyowa kwambiri

Njira zothetsera kubweza kwa PCB:

1. Kutentha kwa tiyi kumayikidwa mkati mwazofunikira mogwirizana ndi malangizo opangira

2. Sinthani kutentha kwa preheating kuti mukonze zofunikira mkati mwamitundu

3. Sinthani liwiro lakutumiza kwa lamba wofalitsira pantchitoyo

4. Pewani bolodi la PCB lomwe limadutsa pamoto wamatini nthawi zambiri

5. Onetsetsani kupanga ndi kusunga muyezo wa bolodi la PCB

6. Mtheradi kulamulira khalidwe la zipangizo PCB bolodi

7. Mu mapangidwe a PCB, zojambula zamkuwa ziyenera kuchepetsedwa momwe zingathere potengera mphamvu zokwanira zamagetsi ndi kudalirika.

8. Onetsetsani ngati magawo omwe mafotokozedwe amtundu wa makampani ali oyenera komanso ngati Zochunira zili mkati mwake.

9. Bwererani ku mafakitale a PCB kuphika kapena kuwononga gasi
