I kaPCBhui a me ka soldering kaʻina hana, SMT chip hana Manufacturers he nui nā limahana a mea kūʻai mai i komo i loko o ka hana, e like me ka plug-in hoʻokomo, ICT ho'āʻo, PCB splitting, manual PCB soldering hana, screw kau ana, rivet kau ana, crimp connector manual pressing, PCB paikikala, a me nā mea ʻē aʻe, ʻo ka hana maʻamau ka mea e ʻohi ai i ka papa me ka lima hoʻokahi, ʻo ia ke kumu nui o ka hiki ʻole o ka BGA a me nā capacitors chip. No laila, no ke aha kēia e hana ai i kahi malfunction? E wehewehe mai kā mākou mea hoʻoponopono iā ʻoe i kēia lā!

ʻO nā pōʻino o ka mālama ʻana i kaPCBpapa me ka lima hoʻokahi:

(1) ʻO ka paʻa ʻana i ka papa PCB me ka lima hoʻokahi e ʻae ʻia no kēlā mau papa kaapuni me ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ʻaʻohe BGA a ʻaʻohe mana chip; akā no kēlā mau kaapuni me ka nui nui, ke kaumaha kaumaha, BGA a me nā capacitors chip ma nā papa ʻaoʻao, pono e pale ʻia. No ka mea hiki i kēia ʻano ʻano ke hana maʻalahi i nā hui solder o BGA, chip capacitance a me ka pale ʻana i ka chip i hāʻule. No laila, i ka palapala kaʻina hana, pono e hōʻike ʻia nā koi no ka lawe ʻana i ka papa kaapuni.

ʻO ka ʻaoʻao maʻalahi o ka paʻa ʻana i kahi PCB me ka lima hoʻokahi, ʻo ia ke kaʻina hana pōʻai kaapuni. ʻO ka wehe ʻana i kahi papa mai kahi kāʻei conveyor a i ʻole ke kau ʻana i kahi papa, ʻike ʻole ka hapa nui o ka poʻe i ka hana o ka paʻa ʻana i ka PCB me ka lima hoʻokahi no ka mea ʻoi aku ka maʻalahi. Ke kuʻi lima, e hoʻopili i ka radiator a hoʻokomo i nā wili. No ka hoʻopau ʻana i kahi hana, e hoʻohana maoli ʻoe i kekahi lima e hana i nā mea hana ʻē aʻe ma ka papa. ʻO kēia mau hana maʻamau e hūnā pinepine i nā pilikia maikaʻi loa.

(2) E hoʻouka i nā wili. I loko o nā hale hana hana chip SMT he nui, i mea e mālama ai i nā kumukūʻai, haʻalele ʻia nā mea hana. Ke hoʻokomo ʻia nā wili ma ka PCBA, hoʻololi pinepine ʻia nā ʻāpana ma ke kua o ka PCBA ma muli o ke ʻano like ʻole, a maʻalahi hoʻi e haki i nā hui solder koʻikoʻi.

(3) Hoʻokomo ʻana i nā ʻāpana ma loko o ka puka

ʻO nā ʻāpana o loko o ka puka, ʻoi aku ka mea hoʻololi me nā alakaʻi mānoanoa, paʻakikī pinepine i ka hoʻokomo pololei ʻana i loko o nā lua kau ma muli o ke kūlana nui o nā alakaʻi. ʻAʻole e hoʻāʻo nā mea hana e ʻimi i kahi ala e pololei ai, e hoʻohana pinepine ana i ka hana paʻi paʻi, e hoʻopiʻi a me ka deformation o ka papa PCB, a e hōʻino pū i nā capacitors chip a puni, resistors, a me BGA.
