He aha ke ʻano hoʻāʻo no SMT?

SMT AOI mīkini

I ka nānā ʻana SMT, hoʻohana pinepine ʻia ka nānā ʻana a me ka nānā ʻana i nā lako optical.ʻO kekahi mau ala he nānā ʻike wale nō, a he mau ʻano hui ʻia kekahi.Hiki iā lāua ke nānā i ka 100% o ka huahana, akā inā hoʻohana ʻia ke ʻano o ka nānā ʻana, e luhi mau ka poʻe, no laila ʻaʻole hiki ke hōʻoia i ka nānā ʻana o ka limahana i ka 100%.No laila, hoʻokumu mākou i kahi hoʻolālā kaulike o ka nānā ʻana a me ka nānā ʻana ma o ka hoʻokumu ʻana i nā wahi mana kaʻina hana maikaʻi.

I mea e hōʻoia ai i ka hana maʻamau o nā lako SMT, e hoʻoikaika i ka nānā ʻana i ka maikaʻi o ka mīkini hana i kēlā me kēia kaʻina hana, i mea e nānā ai i kona kūlana holo, a hoʻonohonoho i nā wahi mana maikaʻi ma hope o kekahi mau kaʻina hana.
Aia kēia mau wahi mana ma nā wahi penei:

1. Nānā PCB
(1) ʻAʻohe deformation o ka papa i paʻi ʻia;
(2) Ina paha ua oxidized ka welding pad;
(3) ʻAʻohe ʻōpala ma ka ʻili o ka papa i pai ʻia;
ʻO ke ala nānā: ʻike maka e like me ke kūlana nānā.

2. ʻIke paʻi pale
(1) Ina ua pau ka pai ana;
(2) Ina he alahaka;
(3) Inā like ka mānoanoa;
(4) ʻAʻole hāʻule kaʻe;
(5) ʻAʻohe ʻokoʻa i ka paʻi ʻana;
ʻO ke ʻano o ka nānā ʻana: nānā ʻike a i ʻole ka nānā ʻana i ke aniani hoʻonui e like me ke kūlana nānā.

3. Ho'āʻo Patch
(1) Ke kūlana kau o nā ʻāpana;
(2) Ina he kulu;
(3) ʻAʻohe hapa hewa;
ʻO ke ʻano o ka nānā ʻana: nānā ʻike a i ʻole ka nānā ʻana i ke aniani hoʻonui e like me ke kūlana nānā.

4. ʻO ka umu houʻike maka
(1) ʻO ke kūlana wili o nā ʻāpana, inā he alahaka, stele, dislocation, solder ball, virtual welding a me nā mea ʻino ʻē aʻe.
(2) Ke kūlana o ka hui solder.
ʻO ke ʻano o ka nānā ʻana: nānā ʻike a i ʻole ka nānā ʻana i ke aniani hoʻonui e like me ke kūlana nānā.
