ʻO ka hapa nui o nā mea kūʻai uila uila ua huikau e pili ana i ke kumukūʻai o nā PCB.ʻO kekahi poʻe me nā makahiki he nui o ka ʻike i ka kūʻai ʻana PCB ʻaʻole maopopo i ke kumu kumu.ʻO ka ʻoiaʻiʻo, ʻo ke kumukūʻai PCB ka mea i haku ʻia i kēia mau mea:
ʻO ka mea mua, ʻokoʻa nā kumukūʻai ma muli o nā mea like ʻole i hoʻohana ʻia i ka PCB.
ʻO ka lawe ʻana i nā papa pālua maʻamau pcb ma ke ʻano he laʻana, ʻokoʻa ka laminate mai FR-4, CEM-3, a pēlā aku me nā pae mānoanoa mai 0.2mm a 3.6mm.ʻOkoʻa ka mānoanoa o ke keleawe mai ka 0.5Oz a i ka 6Oz, ʻo ia mau mea a pau ke kumu kūʻai nui loa.ʻOkoʻa nā kumukūʻai inika soldermask mai nā mea inika thermosetting maʻamau a me nā mea inika ʻōmaʻomaʻo photosensitive.
ʻO ka lua, ʻokoʻa nā kumukūʻai ma muli o nā kaʻina hana like ʻole.
ʻO nā kaʻina hana hana like ʻole ka hopena i nā kumukūʻai like ʻole.E like me ka papa gula a me ka papa tin-plated, ke ʻano o ke alahele a me ke kuʻi ʻana, ka hoʻohana ʻana i nā laina pale siliki a me nā laina kiʻiʻoniʻoni maloʻo e hana i nā kumukūʻai like ʻole, e hopena i ka ʻokoʻa kumukūʻai.
ʻO ke kolu, ʻokoʻa nā kumukūʻai ma muli o ka paʻakikī a me ka paʻakikī.
He ʻokoʻa ke kumukūʻai o ka PCB inā like nā mea a me nā kaʻina hana, akā me nā ʻokoʻa paʻakikī a me ka nui.No ka laʻana, inā he 1000 mau puka ma nā papa kaapuni ʻelua, ʻoi aku ka nui o ke anawaena puka o ka papa hoʻokahi ma mua o 0.6mm a ʻo ke anawaena puka o ka papa ʻē aʻe ma lalo o 0.6mm, e hana ʻia nā kumukūʻai wili ʻokoʻa.Inā like nā papa kaapuni ʻelua i nā noi ʻē aʻe, akā ʻokoʻa ka laulā laina i nā kumu kūʻai like ʻole, e like me ka laulā o ka papa hoʻokahi ma mua o 0.2mm, a ʻo ka mea ʻē aʻe me ka liʻiliʻi ma mua o 0.2mm.Ma muli o ka laulā o nā papa ma lalo o 0.2mm ʻoi aku ka nui o ka hemahema, ʻo ia hoʻi ke kiʻekiʻe o ke kumukūʻai hana ma mua o ka maʻamau.
ʻO ka hā, ʻokoʻa nā kumukūʻai ma muli o nā koi o nā mea kūʻai aku.
E pili pono ana nā koi o ka mea kūʻai aku i ka helu kīnā ʻole i ka hana.E like me ka papa hoʻokahi e like me ka IPC-A-600E class1 pono 98% pass rate, ʻoiai e like me ka class3 pono he 90% pass rate, e hoʻolilo i nā kumukūʻai like ʻole no ka hale hana a alakaʻi i nā loli i nā kumukūʻai huahana.
