Hoʻomaka i ke kaʻina hana SMT patch

SMD hoʻolauna

SMT patch pili i ka abbreviation o ke kaʻina hana kaʻina hana ma ke kumu o PCB.PCB (Printed Circuit Board) he papa kaapuni pai.

ʻO SMT ʻo Surface Mount Technology (Surface Mount Technology) (pōkole no Surface Mounted Technology), ʻo ia ka ʻenehana kaulana loa a me ke kaʻina hana i ka ʻoihana hui uila.
ʻO ka ʻenehana kaapuni ʻili uila (Surface Mount Technology, SMT), i kapa ʻia ʻo ka mauna ʻili a i ʻole ka ʻenehana mauna ʻili.He ʻano ia o nā ʻāpana mauna non-pin a pōkole-lead surface mauna (SMC/SMD no ka pōkole, Kina i kapa ʻia nā ʻāpana chip) i kau ʻia ma ka ʻili o ka papa kaapuni paʻi (Printed Circuit Board, PCB) a i ʻole ka ʻili o nā substrates ʻē aʻe, ma o ka hui Kaapuni a me ka ʻenehana pili i kūʻai ʻia a hui ʻia e nā ʻano e like me ka reflow soldering a i ʻole dip soldering.

Ma lalo o nā kūlana maʻamau, ua hoʻolālā ʻia nā huahana uila a mākou e hoʻohana ai e ka PCB me nā capacitors like ʻole, nā resistors a me nā ʻāpana uila ʻē aʻe e like me ke kiʻina kaapuni i hoʻolālā ʻia, no laila pono nā ʻano mea uila āpau i nā ʻano ʻenehana SMT chip e hana ai, ʻO kāna hana ʻo ia. leak solder paste a patch glue ma luna o nā pad o ka PCB e hoʻomākaukau ai no ke kūʻai ʻana i nā ʻāpana.ʻO nā mea hana i hoʻohanaʻia he mīkini paʻi kiʻi (screen printing machine), aia ma ka mua o ka laina hana SMT.

Kaʻina hana kumu o SMT

1. Paʻi (paʻi kilika): ʻO kāna hana ka paʻi ʻana i ka solder paste a i ʻole ka hoʻopili ʻana i ka mea hoʻopili ma nā pad o ka PCB e hoʻomākaukau ai no ke kūʻai ʻana i nā ʻāpana.ʻO nā mea hana i hoʻohanaʻia he mīkini paʻi kiʻi (screen printing machine), aia ma ka mua o ka laina hana SMT.

2. ʻO ka hāʻawi ʻana i ke kāpili: ʻO ia ka hoʻoheheʻe ʻana i ke kāpili ma ke kūlana paʻa o ka papa PCB, a ʻo kāna hana nui ʻo ia ka hoʻoponopono ʻana i nā ʻāpana i ka papa PCB.ʻO nā mea hana i hoʻohana ʻia he dispenser glue, aia ma ke alo o ka laina hana SMT a i ʻole ma hope o nā mea hoʻāʻo.

3. Ke kau ʻana: ʻO kāna hana e hoʻokomo pono i nā ʻāpana mauna ʻili i ke kūlana paʻa o ka PCB.ʻO nā mea hana i hoʻohanaʻia he mīkini hoʻokomo, aia ma hope o ka mīkini paʻi pale ma ka laina hana SMT.

4. Curing: ʻO kāna hana ka hoʻoheheʻe ʻana i ka mea hoʻopili paʻa, i hoʻopaʻa paʻa ʻia nā ʻāpana mauna ʻili a me ka papa PCB.ʻO nā mea hana i hoʻohana ʻia he umu curing, aia ma hope o ka mīkini hoʻokomo i ka laina hana SMT.

5. Reflow soldering: ʻO kāna hana ka hoʻoheheʻe ʻana i ka paʻi solder, i hoʻopaʻa paʻa ʻia nā ʻāpana mauna ili a me ka papa PCB.ʻO nā mea hana i hoʻohana ʻia he umu reflow/weweling soldering, aia ma hope o ka mīkini hoʻokomo i ka laina hana SMT.

6. Hoʻomaʻemaʻe: ʻO kāna hana ʻo ka wehe ʻana i nā koena kuʻi ʻana i mea ʻino i ke kino kanaka e like me ka flux ma ka papa PCB i hui ʻia.ʻO nā mea hana i hoʻohana ʻia he mīkini holoi, a ʻaʻole hiki ke hoʻopaʻa ʻia ka wahi, ma ka pūnaewele a i ʻole ma waho.

7. Nānā: ʻO kāna hana ka nānā ʻana i ka maikaʻi wili a me ka maikaʻi o ka hui ʻana o ka papa PCB i hui ʻia.ʻO nā mea hana i hoʻohanaʻia e like me ke aniani hoʻonui, microscope, online tester (ICT), flying probe tester, automatic optical inspection (AOI), X-RAY inspection system, functional tester, etc. Hiki ke hoʻonohonohoʻia ka wahi ma kahi kūpono ma ka laina hana e like me ka pono o ka ike.

Hiki i ke kaʻina hana SMT ke hoʻomaikaʻi nui i ka hana pono a me ka pololei o nā papa kaapuni paʻi, a ʻike maoli i ka automation a me ka hana nui o PCBA.

ʻO ke koho ʻana i nā mea hana e kūpono iā ʻoe ke loaʻa pinepine i ʻelua ka hopena me ka hapalua o ka hoʻoikaika.Hāʻawi ʻo Chengyuan Industrial Automation i ke kōkua hoʻokahi a me ka lawelawe no SMT a me PCBA, a hoʻonohonoho i ka hoʻolālā hana kūpono loa iā ʻoe.
