I ka hana ʻana a me ka hana ʻana o ka PCBA, nui nā mea e pili ana i ka maikaʻi o ka welding SMT, e like me ka PCB, nā ʻāpana uila, a i ʻole ka solder paste, nā mea hana a me nā pilikia ʻē aʻe ma kēlā me kēia wahi e hoʻopilikia i ka maikaʻi o ka wili SMT, a laila ʻo ke kaʻina hana lapaʻau PCB. He aha ka hopena i ka maikaʻi o ka welding SMT?

ʻO ke kaʻina hana hoʻomaʻamaʻa PCB ka nui o ka OSP, ka uhi gula uila, ke kīpē / dip tin, ke gula / kala, a me nā mea ʻē aʻe, ke koho kikoʻī o ke kaʻina hana pono e hoʻoholo ʻia e like me ka pono o ka huahana maoli, ʻo ka mālama ʻana i ka PCB kahi hana koʻikoʻi. i ke kaʻina hana PCB, ka mea nui e hoʻonui i ka hilinaʻi kuʻi a me ka hana anti-corrosion a me ka anti-oxidation, no laila, ʻo ke kaʻina hana PCB ʻili ke kumu nui e pili ana i ka maikaʻi o ke kuʻi!

Inā loaʻa kahi pilikia me ka PCB ili lapaʻau kaʻina hana, a laila e alakaʻi mua i ka oxidation a contamination o ka solder hui, e pili pono ana i ka hilinaʻi o ka kuʻihao, ka hopena i ka ilihune kuʻihao, ukali ia e ka PCB ili lapaʻau kaʻina e hoʻopilikia pū. ʻO nā mea mechanical o ka hui solder, e like me ke kiʻekiʻe o ka paʻakikī o ka ʻili, e maʻalahi ke alakaʻi i ka hāʻule ʻana o ka hui solder.
