1. Kuphika

Magawo a PCBA ndi zigawo zomwe sizinagwiritsidwe ntchito kwa nthawi yayitali ndikuwululidwa ndi mpweya zitha kukhala ndi chinyezi. Kuphika iwo patapita nthawi kapena pamaso ntchito kuteteza chinyezi kukhudza PCBA processing.

2. Phala la solder

Phala la solder ndilofunikanso kwambiri pokonza mafakitale a PCBA, ndipo ngati pali chinyezi mu phala la solder, zimakhalanso zosavuta kupanga mabowo a mpweya kapena mikanda ya malata ndi zochitika zina zosafunika panthawi ya soldering.

Posankha phala la solder, sizingatheke kudula ngodya. M'pofunika kugwiritsa ntchito apamwamba solder phala, ndi solder phala ayenera kukonzedwa mogwirizana ndi zofunika processing kwa kutentha ndi oyambitsa ndi okhwima mogwirizana ndi zofunika processing. Kumayambiriro PCBA processing, ndi bwino osati kuvumbula solder phala kwa mpweya kwa nthawi yaitali. Pambuyo kusindikiza solder phala mu ndondomeko SMT, m'pofunika kulanda nthawi reflow soldering.

3. Chinyezi mu msonkhano

Chinyezi cha msonkhano processing ndi yofunika kwambiri chilengedwe chinthu kwa PCBA processing. Nthawi zambiri, imayendetsedwa pa 40-60%.

4. Chopindika cha kutentha kwa ng'anjo

Tsatirani mosamalitsa zofunikira zamafakitale opangira magetsi kuti muzindikire kutentha kwa ng'anjo, ndikukonzekera kukhathamiritsa kutentha kwa ng'anjo. Kutentha kwa preheating zone kumafunika kukwaniritsa zofunikira, kotero kuti kusinthasintha kungathe kusungunuka kwathunthu, ndipo kuthamanga kwa ng'anjo sikungakhale mofulumira kwambiri.

5. Kuthamanga

Mu yoweyula soldering ndondomeko PCBA processing, ndi flux sayenera sprayed kwambiri.

Mayendedwe a Fastlinehttp://www.fastlinepcb.com, fakitale yopangira zida zamagetsi ku Guangzhou, imatha kukupatsirani ntchito zapamwamba za SMT chip processing, komanso luso laukadaulo la PCBA, zida zopangira PCBA kuti muthetse nkhawa zanu. Pet Technology ingathenso kupanga DIP plug-in processing ndi kupanga PCB, electronic circuit board ikupanga ntchito imodzi.
