ʻO ka ʻenehana maikaʻi loa kekahi o nā mea hana pcb maikaʻi loa a me nā mea hoʻolako papa kaapuni paʻi ma Kina
Ma ke aupuni nui o ka ʻenekinia a me ka hana ʻana, aia kahi honua huna o nā lua, kēlā me kēia me kona kumu ponoʻī a me kona kūlana. He kuleana koʻikoʻi kēia mau puka i ka hoʻomaʻamaʻa ʻana i nā hana like ʻole i loko o nā ʻōnaehana mechanical a me nā ʻōnaehana uila. Ma kēia moʻomanaʻo, e hoʻomaka mākou i kahi huakaʻi e ʻimi i nā ʻano puka like ʻole o ka papa kaapuni paʻi. No laila, e hoʻopaʻa i kou mau kāʻei noho a e ʻimi kākou i ka honua hoihoi o kēia mau hiʻohiʻona ʻenehana koʻikoʻi.
Nā ʻano maʻamau o nā puka ma PCB
Ma ka nānā ʻana i kahi papa kaapuni, ʻike kekahi i kahi ʻano o nā lua e lawelawe ana i nā kumu kikoʻī. Loaʻa kēia mau puka Via, PTH, NPTH, Nā puka makapō, nā lua kanu, nā lua Counterbore, nā puka Countersunk, Nā lua wahi, a me nā lua Fiducial. Hoʻokō kēlā me kēia ʻano puka i kahi kuleana a me ka hana i loko o ka PCB, he mea koʻikoʻi ia e hoʻomaʻamaʻa iā ʻoe iho me kā lākou mau hiʻohiʻona e hoʻomaʻamaʻa i ka hoʻolālā PCB maikaʻi loa.
1. Via Holes
Ma nā puka he mau puka liʻiliʻi e hoʻohui i nā ʻāpana like ʻole o kahi papa kaapuni paʻi (PCB). Hoʻomaʻamaʻa lākou i ka holo ʻana o nā hōʻailona a me ka mana ma waena o nā papa, e hiki ai i ka hoʻolālā kaapuni kūpono a me ka lawe ʻana. Hiki ke hoʻokaʻawale ʻia ʻo Vias i ʻelua ʻano: Plated Through-Hole (PTH) a me Non-Plated Through-Hole (NPTH), kēlā me kēia lawelawe i nā hana like ʻole.
2. PTH (Plated Through-Hole)
Plated Through-Holes (PTH) he mau vias me nā mea conductive e uhi ana i nā paia o loko. Hoʻokumu nā PTH i nā pilina uila ma waena o nā papa like ʻole o kahi PCB, e ʻae i ka hele ʻana o nā hōʻailona a me ka mana. He kuleana koʻikoʻi ko lākou i ka hoʻopili ʻana i nā ʻāpana, hoʻomaʻamaʻa i ke kahe o ke au uila, a me ka hōʻoia ʻana i ka hana o ke kaapuni.
3. NPTH (Non-Plated Through-Hole)
Non-Plated Through-Hole (NPTH) nele i ka uhi conductive ma ko lakou mau paia o loko, i kupono no na hana mechanical wale no. Hoʻohana ʻia kēia mau puka no ke kākoʻo mechanical, alignment, a i ʻole ma ke ʻano he alakaʻi kūlana, me ka ʻole o ka hoʻokumu ʻana i nā pili uila. Hāʻawi nā NPTH i ka paʻa a me ka pololei, e hōʻoia ana i ka alignment kūpono o nā ʻāpana i loko o ka papa kaapuni. ʻO ka ʻokoʻa nui ma waena o PTH a me NPTH ʻo ia ka pahu keleawe e uhi ʻia i ka paia o ka lua a ʻaʻole pono ka NPTH e hana i ka pā.
4. Puka Makapo
ʻO nā puka makapō he mau puka i wili ʻia e komo i hoʻokahi ʻaoʻao o ka papa kaapuni. Hoʻohana nui ʻia lākou e hoʻopili i ka papa o waho o ka papa me ka ʻāpana o loko, e hiki ai ke kau ʻia nā ʻāpana ma kekahi ʻaoʻao ʻoiai e hūnā ʻia mai kekahi ʻaoʻao. Hāʻawi nā puka makapō i ka versatility a kōkua i ka hoʻonui ʻana i ka lewa ma nā hoʻolālā papa kaapuni paʻakikī.
5. Na Lua i kanuia
Hoʻopili piha ʻia nā lua i kanu ʻia i loko o kahi papa kaapuni, e hoʻopili ana i nā ʻāpana o loko me ka ʻole e hoʻonui i nā papa waho. Ua hūnā ʻia kēia mau puka mai nā ʻaoʻao ʻelua o ka papa a lawelawe e hoʻokumu i nā pilina a me nā ala ma waena o nā papa o loko. ʻO nā lua i kanu ʻia e ʻae i nā hoʻolālā papa kaapuni ʻoi aku ka paʻakikī, e hōʻemi ana i ka paʻakikī o nā ala ala ala a hoʻonui i ka hana holoʻokoʻa o ka papa. Hāʻawi lākou i kahi hopena maʻemaʻe a paʻa ʻole me ka ʻike ʻole o ka ʻili.
6. Puka Kūlike
ʻO nā puka counterbore he mau ʻāpana cylindrical i hana ʻia e hoʻokipa i nā poʻo o nā bolts, nati, a i ʻole nā wili. Hāʻawi lākou i kahi lua palahalaha e hiki ai i nā mea hoʻopaʻa ke noho malū a i ʻole ma lalo iki o ka ʻili o ka mea. ʻO ka hana nui o nā puka counterbore ʻo ia ka hoʻonui ʻana i ka aesthetics a me ka hana o kahi hoʻolālā ma o ka hāʻawi ʻana i kahi hiʻohiʻona maʻemaʻe a kūlike. Loaʻa pinepine ʻia kēia mau puka i ka hana lāʻau, ka hana metala, a me nā noi ʻenekinia kahi e makemake ʻia ai kahi ʻili i hūnā ʻia a nui paha.
7. Puka Countersunk
ʻO nā puka Countersunk he mau ʻāpana conical i hoʻolālā ʻia no ka hoʻopaʻa ʻana i nā poʻo ʻokiʻoki o nā wili a i ʻole nā mea paʻa. Hoʻohana ʻia lākou e hōʻoia i ka waiho ʻana o nā poʻo wili a i ʻole ma lalo iki o ka ʻili. Hoʻohana nā puka Countersunk i nā kumu nani a me nā kumu kūpono, e hāʻawi ana i kahi hoʻopau nani a maikaʻi ʻole ʻoiai e hōʻemi ana i ka pilikia o nā snags a i ʻole protrusions. ʻO kā lākou versatility e kūpono iā lākou no nā noi like ʻole, mai ka hana ʻana i nā lako a i ka ʻenehana aerospace.
8. Wahi Wahi
ʻO nā lua wahi, ʻike ʻia hoʻi ʻo Reference Holes a i ʻole Tooling Holes, e lilo i wahi kuhikuhi nui no ka hoʻonohonoho ʻana a me ka hoʻonohonoho ʻana i nā ʻāpana, nā ʻāpana, a i ʻole nā mea paʻa i ka wā o ka hana ʻana a i ʻole nā kaʻina hana. Hoʻonohonoho pono ʻia kēia mau lua i kahi hoʻolālā e hōʻoia i ka alignment pololei a paʻa, hiki i ka hui kūpono a me ka hōʻemi ʻana i nā hewa.
9. Puka Pili
ʻO nā puka Fiducial, i kapa ʻia ʻo Fiducial Marks a i ʻole Alignment Marks, he mau puka liʻiliʻi liʻiliʻi a i ʻole hōʻailona i kau ʻia ma kahi ʻili a i ʻole PCB (Printed Circuit Board). ʻO kēia mau puka he mau wahi kuhikuhi ʻike no nā ʻōnaehana ʻike, nā kaʻina hana maʻemaʻe, a i ʻole nā kiʻi kamepiula ʻike mīkini.
I ko mākou hoʻopau ʻana i kā mākou huakaʻi ma ka honua hoihoi o nā lua i ka ʻenekinia, ua loaʻa iā mākou ka ʻike hohonu o nā hana a me nā kūlana o nā lua counterbore, nā lua countersunk, ma nā lua, PTH, NPTH, nā puka makapō, a me nā lua kanu. ʻO kēia mau puka he mau mea koʻikoʻi i nā ʻoihana like ʻole, e hāʻawi ana i ka aesthetics, ka hana, a me ka pono o nā hoʻolālā.
Ma hope o ka hoʻolauna ʻana i kēlā me kēia o lākou, pono ʻoe e ʻike hohonu i kā lākou mau hana, manaʻolana he mea kōkua kēia iā ʻoe i nā lua hoʻolālā ma kāu papahana PCB!!
