Inā nīnau ʻia ʻoe he aha ke kala o ka papa kaapuni, manaʻo wau he ʻōmaʻomaʻo ka pane mua o kēlā me kēia. ʻOiaʻiʻo, ʻo ka hapa nui o nā huahana i hoʻopau ʻia i ka ʻoihana PCB he ʻōmaʻomaʻo. Akā me ka hoʻomohala ʻana o ka ʻenehana a me nā pono o nā mea kūʻai aku, ua puka mai nā ʻano kala like ʻole. E hoʻi i ke kumu, no ke aha he ʻōmaʻomaʻo ka nui o nā papa? E kamaʻilio kākou i kēia lā!
Kapa ʻia ka ʻāpana ʻōmaʻomaʻo he poloka solder. ʻO kēia mau mea he resins a me nā puaʻa,ʻo ka'āpana'ōmaʻomaʻo he mau'ōmaʻomaʻo'ōmaʻomaʻo, akā me ka uluʻana o kaʻenehana hou, ua hoʻonuiʻia i nā kala'ē aʻe. ʻAʻohe mea ʻokoʻa me ka pena hoʻonaninani. Ma mua o ka paʻi ʻia ʻana o ke kūʻai ʻana ma ka papa kaapuni, hoʻopili ʻia ke kūpaʻa solder a kahe. Ma hope o ka paʻi ʻana ma ka papa kaapuni, paʻakikī ka resin ma muli o ka wela a "hoʻōla." ʻO ke kumu o ke kuʻekuʻe kūʻē ʻana ʻo ia ka pale ʻana i ka papa kaapuni mai ka wai, oxidation a me ka lepo. ʻO kahi wale nō i uhi ʻole ʻia e ka poloka solder i kapa ʻia he pad a hoʻohana ʻia no ka paʻi solder.
Ma keʻano laulā, koho mākou i ka'ōmaʻomaʻo no ka meaʻaʻole ia e hoʻonāukiuki i nā maka, aʻaʻole maʻalahi i ka hana a me ka mālamaʻana i nā limahana e nānā i ka PCB no ka manawa lōʻihi. I ka hoʻolālā ʻana, ʻo nā kala i hoʻohana mau ʻia he melemele, ʻeleʻele a ʻulaʻula. Ua pena ʻia nā kala ma ka ʻili ma hope o ka hana ʻia ʻana.
ʻO ke kumu ʻē aʻe he ʻōmaʻomaʻo ka waihoʻoluʻu maʻamau, no laila ʻoi aku ka nui o ka pena ʻōmaʻomaʻo i ka hale hana, no laila he haʻahaʻa ke kumukūʻai o ka aila. ʻO kēia no ka mea i ka lawelawe ʻana i kahi papa PCB, ʻoi aku ka maʻalahi o ka hoʻokaʻawale ʻana i nā uwea ʻokoʻa mai ke keʻokeʻo, ʻoiai ʻeleʻele a me ke keʻokeʻo paʻakikī ke ʻike. No ka hoʻokaʻawale ʻana i kāna mau helu huahana, hoʻohana kēlā me kēia hale hana i ʻelua kala e hoʻokaʻawale i ka moʻo kiʻekiʻe mai ka moʻo haʻahaʻa. No ka laʻana, ʻo Asus, kahi hui motherboard computer, ʻo ka papa melemele ka haʻahaʻa haʻahaʻa, ʻo ka papa kiʻekiʻe ka papa kiʻekiʻe. He kiʻekiʻe ka rebound o Yingtai, a he haʻahaʻa ka papa ʻōmaʻomaʻo.
1. Aia nā hōʻailona ma ka papa kaapuni: ʻO ka hoʻomaka ʻana o R ka resistor, ʻo ka hoʻomaka ʻana o L ka wili inductor (ʻo ka mea maʻamau e ʻeha ʻia ka wili a puni ke apo hao, ua pani ʻia kekahi hale), ʻo ka hoʻomaka o C ka capacitor (cylindrical kiʻekiʻe, wahī ʻia i loko o ka plastic, electrolytic capacitors me ke keʻa indentation, flat chip capacitors), ʻo nā wāwae ʻelua ʻelua he diodes, ʻekolu mau wāwae he transistors, a he nui nā wāwae i hui pū ʻia.
2, thyristor rectifier UR; Loaʻa i ke kaapuni hoʻomalu ka mana hoʻoponopono VC; Mea hoʻohuli UF; Mea hoʻololi UC; UI Inverter; Kaa M; Asynchronous motor MA; ʻO ka mīkini kaʻa like ʻole MS; Dc motor MD; ʻEha-rotor induction motor MW; ʻO ka moʻa moʻa MC; Kiwi uila YM; Solenoid valve YV, etc.
3, heluhelu lōʻihi i hoʻopili ʻia i kekahi ʻāpana o ke kiʻikuhi ma ka papa kaapuni nui o ka ʻike hoʻopuka inoa.
