Māhele: nā mea like ʻole e pili ana i ke kumukūʻai o kahi papa PCB
ʻO ke kumu kūʻai o PCB he puʻupuʻu i nā mea kūʻai aku he nui, a he nui ka poʻe e noʻonoʻo pehea e helu ʻia ai kēia mau kumukūʻai i ke kau ʻana i nā kauoha ma ka pūnaewele. E kamaʻilio pū kākou e pili ana i nā ʻāpana o ke kumukūʻai PCB.
- ʻO nā mea like ʻole i hoʻohana ʻia ma PCB ke alakaʻi i nā ʻano kumukūʻai
No ka laʻana, Ordinary papalua panel, ka pā maʻamau i FR4 (Sheng yi, Kingboard, Guoji, ekolu kumu kūʻai mai luna a lalo), pā mānoanoa mai 0.2 mm a 3.0 mm, keleawe mānoanoa mai 0.5 oz a 3 oz, keia mau mea a pau i loko. ka mea pā ma ka ʻokoʻa kumu kūʻai nui; I loko o ka inika kū'ē, ka aila thermosetting maʻamau a me ka ʻaila ʻōmaʻomaʻo photosensitive aia kekahi ʻokoʻa kumu kūʻai.
2.ʻO nā kaʻina hana lapaʻau ili ʻokoʻa e alakaʻi i nā kumukūʻai like ʻole
Common ili lapaʻau kaʻina hana: OSP (oxidation kū'ē), aia no HASL, Lead-noa HASL (kaiapuni), gula plating, Immersion gula a me kekahi hui kaʻina hana, a no laila, ma luna o ke kumu kūʻai i oi pipiʻi i loko o ka wā e hiki mai.
3.PCB pono'ī ma muli o ka paʻakikī like ʻole o ka ʻokoʻa kumu kūʻai.
He 1000 puka ma na papa kaapuni elua. Inā ʻoi aku ka nui o ka lua o ka papa hoʻokahi ma mua o 0.2mm, ʻoi aku ka nui o ka lua o ka papa ʻē aʻe ma mua o 0.2mm. Inā like ʻelua ʻano papa kaapuni, akā ʻokoʻa ka laulā laina a me ka spacing laina, ʻoi aku ka nui o kekahi ma mua o 4mil a ʻoi aku ka liʻiliʻi o kekahi ma mua o 4mil, ʻo ia hoʻi ke kumu o nā kumukūʻai hana like ʻole. ʻAʻole hiki i kekahi poʻe ke hele i ka hoʻolālā o ka holo ʻana o ka pā maʻamau no ka hoʻohui ʻana i ke kālā, no ka laʻana ʻo ka hapalua puka, kanu i ka puka makapō, ka lua kīʻaha, kaomi i ka pā kī e paʻi i ka ʻaila kalapona.
