I ka ʻoihana uila, ka papa kaapuni i paʻi ʻia (PCB) ka mea nui o nā huahana uila like ʻole. ʻO ka maikaʻi o ke kūʻai ʻana o nā ʻāpana ma ka PCB pili pono i ka hana o ka huahana. No laila, ʻo ka nānā ʻana i ka maikaʻi a me ka hoʻāʻo ʻana i nā papa PCB ʻo ia ka mana maikaʻi o nā mea hana noi PCB. He loulou pono ole. I kēia manawa, hana ʻia ka hapa nui o ka PCB soldering quality inspection work ma o manual visual inspection. ʻO ka mana o nā kumu kanaka he maʻalahi ke nalo a ʻike hewa ʻole.

No laila, pono ka ʻoihana PCB i ka nānā ʻana i ka ʻike maka, a ʻoi aku ka pipiʻi o nā huahana haole. Ma muli o kēia kūlana, hoʻomaka ka ʻāina e hoʻomohala i kēia. Pūnaehana ʻIke. Ke aʻo nui nei kēia pepa i ka ʻike ʻana i nā hemahema o ka papa PCB: ka ʻike ʻana i ke kū ʻana o ke apo kala, ka ʻike ʻana i ka leakage welding a me ka ʻike ʻana i ka polarity capacitor.

ʻO ke kaʻina hana i loko o kēia pepa, ʻo ia ka hoʻohui ʻana i ke ʻano hoʻohālikelike kuhikuhi a me ke ʻano hoʻohālikelike ʻole e kiʻi i ke kiʻi papa PCB mai ka pahu kiʻi kiʻi, a hoʻohana i nā ʻano o ke kūlana kiʻi, preprocessing kiʻi a me ka ʻike kiʻi. hana ʻimi ʻakomi. Ma o ka hoʻokolohua o nā kiʻi PCB he nui, ua hoʻomaikaʻi ʻia ke ʻano hoʻonohonoho o nā hiʻohiʻona kiʻi PCB e loaʻa ai ke kūlana kiʻi pololei.

ʻO ka māhele maʻamau o ka haʻihaʻi he mea nui. ʻO kēia ka papa kaapuni a me ka papa maʻamau. Hana i ka ʻanuʻu mua o ka pāʻani pololei. Ma ke kiʻi preprocessing hapa, he hou geometric hoʻoponopono kaʻina hana e hoʻoponopono i ke kiʻi e kiʻi pololei PCB kiʻi a me ka kiko’ī kiko kiko o kēlā me kēia māhele, a hana kiʻi binarization, median kānana, kaʻike maka a me nāʻano’ē aʻe e loaʻa i ka maikaʻi Recognition. Ma ka ʻike kiʻi aʻe o ke kiʻi hopena, lawe ʻia nā hiʻohiʻona mai ke kiʻi ma hope o ka hana mua ʻana, a ua ʻae ʻia nā ʻano ʻike like ʻole no nā hemahema wili like ʻole.

Ke hoʻohana nei i nā ʻano helu helu no ka unuhi ʻana i ka ikehu kala maʻamau e ʻike pono i ke kū ʻana o ke apo kala, a hoʻoholo i ka ʻike ʻana i ke kū ʻana o ke apo kala mai ka ʻāpana kala a hiki i ka hoʻopiha piha ʻana. E pili ana i nā hiʻohiʻona geometric o ka polar capacitor, ua hoʻohana ʻia ke ʻano ʻike geometric i ka hoʻohana ʻana i ka welding leakage component. Ua loaʻa i ke ala ʻike probabilistic nā hopena ʻike maikaʻi. No laila, loaʻa i kēia ʻano ka waiwai kuhikuhi maikaʻi no ka ʻike maʻalahi o ka ʻike defect PCB ma Kina.
