Hiki ke ʻike ʻia he nui nā puka nui a me nā puka liʻiliʻi ma ka papa kaapuni, a hiki ke ʻike ʻia he nui nā puka mānoanoa, a ua hoʻolālā ʻia kēlā me kēia puka no kāna kumu. Hiki ke hoʻokaʻawale ʻia kēia mau lua i PTH (Plating Through Hole) a me NPTH (Non Plating Through Hole) plating through hole, a ke ʻōlelo nei mākou "ma o ka lua" no ka mea hele maoli ia mai kekahi ʻaoʻao o ka papa a i kekahi, ʻoiaʻiʻo, ma ma waho aʻe o ka puka ma ka papa kaapuni, aia kekahi mau puka ʻē aʻe ʻaʻole ma ka papa kaapuni.
ʻO nā hua'ōlelo PCB: ma o ka lua, ka puka makapō, ka lua kanu.
1. Pehea e hoʻokaʻawale ai i ka PTH a me ka NPTH i loko o nā lua?
Hiki ke noʻonoʻo ʻia inā loaʻa nā māka electroplating mālamalama ma ka paia o ka puka. ʻO ka lua me nā kaha electroplating ʻo PTH, a ʻo ka lua me ka ʻole o nā kaha electroplating ʻo NPTH. E like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei:
2. KaUakamai o NPTH
ʻIke ʻia ʻoi aku ka nui o ka puka o NPTH ma mua o PTH, no ka mea, hoʻohana ʻia ʻo NPTH ma ke ʻano he wili laka, a hoʻohana ʻia kekahi e hoʻokomo i kekahi mau pilina ma waho o ka mea hoʻohui. Eia kekahi, e hoʻohana ʻia kekahi i mea hoʻāʻo ma ka ʻaoʻao o ka pā.
3. Ka hoohana ana o PTH, He aha ka Via?
ʻO ka maʻamau, hoʻohana ʻia nā lua PTH ma ka papa kaapuni ma nā ala ʻelua. Hoʻohana ʻia kekahi no ka wili ʻana i nā wāwae o nā ʻāpana DIP kuʻuna. Pono ka puka o kēia mau puka ma mua o ke anawaena o nā wāwae wili o nā ʻāpana, i hiki ke hoʻokomo ʻia nā ʻāpana i loko o nā lua.
ʻO kekahi PTH liʻiliʻi liʻiliʻi, maʻamau i kapa ʻia ma o (conduction hole), ua hoʻohana ʻia e hoʻohui a me ka conduction circuit board (PCB) ma waena o ʻelua a ʻoi aku paha o nā ʻāpana o ka laina keleawe keleawe, no ka mea, ua haku ʻia ʻo PCB me nā papa keleawe he nui i ahu, kēlā me kēia papa o ʻO ke keleawe (ke keleawe) e hoʻopaʻa ʻia me kahi papa o ka insulation layer, ʻo ia hoʻi, ʻaʻole hiki ke kamaʻilio ʻia ke keleawe me kekahi, ʻo ka pilina i kāna hōʻailona ma o, ʻo ia ke kumu i kapa ʻia ai ʻo "pass through hole" ma ka ʻōlelo Kina. Via no ka mea ʻike ʻole ʻia nā puka mai waho. No ka mea, ʻo ke kumu o ka via e alakaʻi i ke keleawe keleawe o nā papa like ʻole, pono ia i ka electroplating e hana ai, no laila he ʻano PTH hoʻi ʻo via.
