Kodi Zomwe Zimayambitsa SMT Component Drop ndi Chiyani?

PCBA kupanga ndondomeko, chifukwa cha zifukwa zingapo kudzachititsa kuti chigawo dontho, ndiye anthu ambiri nthawi yomweyo kuganiza kuti mwina chifukwa PCBA kuwotcherera mphamvu sikokwanira chifukwa.chigawo dontho ndi kuwotcherera mphamvu ali ndi ubale wamphamvu kwambiri, koma zifukwa zina zambiri adzachititsanso zigawo zikuluzikulu kugwa.

chigawo soldering mphamvu miyezo

Pamene kukankhira kunja kupitirira muyezo uwu, chigawocho chidzagwa, chomwe chitha kuthetsedwa mwa kusintha phala la solder, koma kukankhira kwake sikokulirapo kungapangitsenso kugwa kwa chigawocho.

Zina zomwe zimapangitsa kuti zigawo ziwonongeke ndizo.

1. pad mawonekedwe factor, zozungulira PAD mphamvu kuposa amakona anayi pad mphamvu kukhala osauka.

2. chigawo cha elekitirodi ❖ kuyanika si zabwino.

3. PCB mayamwidwe chinyezi wapanga delamination, palibe kuphika.

4. PCB pad mavuto, ndi PCB PAD kapangidwe, okhudzana kupanga.

Chidule

PCBA kuwotcherera mphamvu si chifukwa chachikulu cha zigawo kugwa, zifukwa zambiri.
