7. Kusauka kwa mkuwa wa pamwamba pa bolodi la dera.

Pali zifukwa zambiri m'badwo wa PCBA solder mavuto, komanso ndi zovuta kulamulira ndondomeko.Dummy soldering imapangitsa kuti dera lizigwira ntchito molakwika, liwonekere likakhala labwino komanso loyipa, ndikupanga phokoso, kuyezetsa dera, kugwiritsa ntchito ndi kukonza zoopsa zobisika.Komanso, palinso mbali ya olowa pafupifupi solder dera anayamba kugwira ntchito kwa nthawi yaitali, kukhalabe kukhudzana akadali zabwino, n'kovuta kupeza.Chifukwa chake ndikofunikira kukhala ndi njira yabwino yodziwira kuti muzindikire mwachangu kuti mankhwalawo ndi oyipa.

II.The anapeza PCBA zabodza solder njira

1. Malinga ndi maonekedwe a cholephera chodabwitsa kudziwa kuchuluka kwa kulephera.

2. Maonekedwe a kuwonetsetsa, kuyang'ana pa zigawo zazikulu ndi zigawo zomwe zimakhala ndi kutentha kwakukulu.
