Mea Hana PCB hoʻokūkū

ʻO SMT ka pōkole no Surface Mounted Technology, ka ʻenehana kaulana loa a me ke kaʻina hana i ka ʻoihana hui uila. Ua kapa ʻia ka ʻenehana uila ʻo Surface Mount Technology (SMT) ʻo Surface Mount a i ʻole Surface Mount Technology. He ʻano o ka ʻenehana hui Circuit e hoʻokomo i nā ʻāpana hui alakaʻi alakaʻi ʻole a pōkole paha (SMC/SMD ma ka ʻōlelo Kina) ma ka ʻili o Printed Circuit Board (PCB) a i ʻole kahi substrate surface, a laila welds a hōʻuluʻulu ma o ka reflow welding a i ʻole. kuʻi wili.

Ma keʻano laulā, hana ʻia nā huahana uila a mākou e hoʻohana ai i ka PCB me nā capacitors like ʻole, nā mea pale a me nā ʻāpana uila ʻē aʻe e like me ke kiʻina kaapuni, no laila pono nā ʻano mea uila āpau i nā ʻenehana hana SMT chip e hana ai.

ʻO nā mea kaʻina hana maʻamau o SMT: ka paʻi ʻana i ka pale (a i ʻole ka hāʻawi ʻana), ke kau ʻana (curing), reflow welding, hoʻomaʻemaʻe, hoʻāʻo, hoʻoponopono.

1. Paʻi pale: ʻO ka hana o ka paʻi pale ʻana ʻo ia ka hoʻokahe ʻana i ka paʻi solder a i ʻole ka hoʻopili ʻana i ka mea hoʻopili ma luna o ka pad solder o ka PCB e hoʻomākaukau ai no ka hoʻopili ʻana i nā ʻāpana. ʻO nā mea hana i hoʻohana ʻia ʻo ia ka mīkini paʻi pale (screen printing machine), aia ma ka ʻaoʻao mua o ka laina hana SMT.

2. Hoʻopili ʻia ke kāpili: Hoʻoheheʻe ʻo ia i ke kāpili i ke kūlana paʻa o ka papa PCB, a ʻo kāna hana nui ka hoʻoponopono ʻana i nā ʻāpana i ka papa PCB. ʻO nā mea hana i hoʻohana ʻia ʻo ia ka mīkini dispensing, aia ma ka ʻaoʻao mua o ka laina hana SMT a i ʻole ma hope o nā mea hoʻāʻo.

3. Ka mauna: ʻO kāna hana ʻo ia e hoʻokomo pono i nā ʻāpana hui honua i ke kūlana paʻa o PCB. ʻO nā mea hana i hoʻohana ʻia ʻo ia ka mīkini hoʻokomo SMT, aia ma hope o ka mīkini paʻi pale ma ka laina hana SMT.

4. Curing: ʻO kāna hana ka hoʻoheheʻe ʻana i ka SMT adhesive i hiki ke hoʻopili paʻa ʻia nā ʻāpana hui honua a me ka papa PCB. ʻO nā mea hana i hoʻohana ʻia ʻo ka curing furnace, aia ma ke kua o ka laina hana SMT SMT.

5. Reflow kuʻihao: ka hana o ka reflow kuʻihao mea e hoohehee i ka solder paʻi, no laila, ili hui 'āpana a me ka PCB papa paa paa pu. ʻO nā mea hana i hoʻohana ʻia ʻo ka reflow welding umu, aia ma ka laina hana SMT ma hope o ka mīkini hoʻokomo SMT.

6. Hoʻomaʻemaʻe: ʻO ka hana ka wehe ʻana i ke koena kuʻi ʻana e like me ka flux ma ka PCB i hui ʻia i mea pōʻino i ke kino kanaka. ʻO nā mea hana i hoʻohana ʻia ʻo ia ka mīkini hoʻomaʻemaʻe, ʻaʻole hiki ke hoʻopaʻa ʻia ke kūlana, hiki ke ma ka pūnaewele, a i ʻole ma ka pūnaewele.

7. ʻIke: Hoʻohana ʻia ia e ʻike i ka maikaʻi kuʻi ʻana a me ka maikaʻi o ka hui ʻana o ka PCB i hui ʻia. ʻO nā mea hana i hoʻohanaʻia e like me ke aniani hoʻonui, microscope, mea ho'āʻo ma ka laina (ICT), mea ho'āʻo o ka nila lele, ka ho'āʻo optical (AOI), ka pūnaewele ho'āʻo X-ray, ka mea ho'āʻo hana, a pēlā aku. ʻāpana o ka laina hana e like me nā koi o ka nānā.

8.Repair: hoʻohana ʻia e hana hou i ka PCB i ʻike ʻia me nā hewa. ʻO nā mea hana i hoʻohana ʻia ʻo ia nā hao hao, nā hale hana hoʻoponopono, a me nā mea ʻē aʻe.
