ʻO ka pilikia ʻeleʻele ʻeleʻele o ka papa kaapuni ʻo PCBA he mea maʻamau ʻoi aku ka maikaʻi ʻole o ka papa kaapuni, ʻo ia ka hopena o ka PCBA welding disc ʻeleʻele no nā kumu he nui, akā ma muli o nā kumu penei:

1, pad oxidation: Inā ʻike ʻia ka PCBA pad i ka haʻahaʻa no ka manawa lōʻihi, e hoʻoneʻe ʻia ka ʻili o ka pad, e hana ana i kahi kiʻi ʻoniʻoni ma ka ʻili o ka pad, e hopena i ka ʻeleʻele, no laila, i ka wā e mālama ai i ka PCBA, pono e uku ʻia i ka mālama ʻana i ke kaiapuni i maloʻo, a i ka manawa like, pono e hoʻokaʻawale ʻia ka PCBA i ka manawa e pale ai i kona ʻike lōʻihi i ka lewa!

2, nā pilikia kaʻina hana kuʻi: i ka reflow welding a i ʻole ka nalu nalu, inā kiʻekiʻe ke kiʻekiʻe o ka welding a i ʻole ka lōʻihi o ka manawa kuʻi, e alakaʻi pū ia i ka oxidation o ka welding pad ʻeleʻele, ʻo ia ka hopena ma muli o ka welding. ʻoi aku ka mahana ma mua o ka pae wela i manaʻo ʻia o ka solder, ka hopena i ka wikiwiki o ka oxidation kaʻina, no laila i ka hana kuʻi ʻana pono e like me nā kikoʻī hana no ka welding!

3, pilikia solder: ʻo ka solder e pili ana i ka solder paste, tin, maikaʻi a maikaʻi ʻole paha ka maikaʻi o ka solder, inā hoʻohana ʻia ka solder maikaʻi ʻole, e hana pū ka solder i nā mea ʻino a me nā haumia i hoʻokuʻu ʻia, ka hopena i ka papa ʻeleʻele, no laila, i ke koho ʻana i ka solder, pono mākou e pale i ka hoʻohana ʻana i ka solder haʻahaʻa haʻahaʻa!

4, hoʻomaʻemaʻe pilikia: ʻO ka mea maʻamau, i ka hihia o ka hoʻohana ʻana i ka flux pono e hoʻomaʻemaʻe i ka papa, i mea e wehe ai i ke koena flux ma ka papa, a inā ʻaʻole i hoʻopau piha ʻia ke koena o ka flux, a laila hiki ke hoʻohaʻahaʻa i kēia koena flux. a i ʻole carbonize i nā wela kiʻekiʻe, i ʻike ʻia ka ʻeleʻele o ka papa. No laila, pono loa ka hoʻomaʻemaʻe manawa ma hope o ka welding!

5, nā pilikia ʻāpana: inā ʻaʻole maikaʻi ka maikaʻi o nā ʻāpana uila, a i ʻole nā ​​​​mea o ka pine ʻāpana, hiki ke alakaʻi i ke ʻano o ka disc welding ʻeleʻele, no laila, i ke koho ʻana i nā ʻāpana uila, pono mākou e koho i ka maikaʻi maikaʻi. nā mea e hōʻoia i ka maikaʻi o ka uhi a me ka mea pin o nā mea i kūpono.

ʻO ka mea i luna ke kumu nui o ka PCBA welding tray ʻeleʻele, a ma muli o nā kumu like ʻole, hiki iā mākou ke koho i nā ana hoʻomaikaʻi kūpono, i mea e hōʻemi pono ai i ka pilikia o ka PCBA welding tray ʻeleʻele, hoʻomaikaʻi i ka maikaʻi o nā huahana!
