Pehea e ʻike maopopo ai i nā hemahema ʻike ʻole o PCBA?

Nā Kūlana Nānā X-RAY

1. ʻAʻohe offset o nā hui solder BGA:
Nā pae hoʻoholo: ʻae ʻia inā emi ka offset ma lalo o ka hapalua o ke anapuni o ka pad solder; Ke ʻoi aku ka nui o ka offset ma mua a i ʻole ka hapalua o ke anapuni o ka pā solder, e hōʻole ʻia.

2. ʻAʻohe kaapuni pōkole o nā hui solder BGA:
Nā pae hoʻoholo: Inā ʻaʻohe pili tin ma waena o nā hui solder, ʻae ʻia; Ke loaʻa ka pilina solder ma waena o nā hui solder, e hōʻole ʻia.

3. BGA solder ami me ka puka ole:
Nā pae hoʻoholo: ʻae ʻia kahi ʻāpana ʻole ma lalo o 20% o ka nui o ka ʻāpana o ka hui solder; Inā ʻoi aku ka nui o ka hakahaka ma mua o ka 20% o ka nui o ka ʻāpana o ka hui solder, e hōʻole ʻia.

4. ʻAʻohe hemahema o ka pī ma nā hui solder BGA:
Nā pae hoʻoholo: E ʻae i ka wā e hōʻike ʻia ai nā pōpō tin a pau i ka nui, ʻaʻahu like a kūlike; Inā ʻoi aku ka liʻiliʻi o ka nui o ka pōpō tini ke hoʻohālikelike ʻia me nā pōlele ʻē aʻe a puni, pono e hōʻole ʻia.

5. ʻO ka maʻamau o ka nānā ʻana no ka papa honua E-PAD o nā ʻāpana papa QFP/QFN no kekahi mau huahana, ʻo ia ka nui o ka ʻāpana tin ma mua o 60% o ka nui o ka ʻāpana (ʻehā mau pahu i hui pū ʻia e hōʻike ana i ke kūʻai ʻana maikaʻi), a ʻo ka lakene laʻana. he 20%.

1. Pahu ho'āʻo: Nā papa PCBA me BGA/LGA a me nā ʻāpana papa lepo;

2. Ho'āʻo pinepine:

① Ma hope o ka hoʻololi ʻana, hōʻoia ka poʻe loea inā loaʻa nā hemahema o ka papa solder paste mua a me ka mauna ʻili BGA, a laila hoʻomau i ka hele ʻana i ke keʻena ma hope o ka hōʻoia ʻana ʻaʻohe pilikia;

② Hoʻopaʻa ka poʻe loea inā loaʻa nā pilikia me ka BGA soldering o ka solder paste board mua ma hope o ka hele ʻana i loko o ke keʻena, a laila hoʻokomo i ka hana inā ʻaʻohe pilikia;

③ I ka wā hana maʻamau, nā limahana i koho ʻia ke kuleana no ka hoʻāʻo ʻana, a inā kauoha o ≤ 100pcs, 100% e hoʻāʻo piha ʻia; 101-1000pcs e hoʻohālikelike ʻia no 30%, kauoha ʻoi aku ma mua o 1001pcs e hoʻohālikelike ʻia no 20%;

④ I ke kaʻina hana maʻamau, hana ʻo IPQC i nā hoʻāʻo hoʻāʻo ma 2 mau ʻāpana nui i kēlā me kēia hola;

⑤ Pono e hoʻāʻo piha ʻia nā huahana a 100% mālama ʻia nā kiʻi.

3. Inā he mau hemahema, pono e mālama ʻia nā kiʻi, a e hoʻopaʻa ʻia ke ʻano BOM, barcode serial number a me nā hopena hoʻāʻo o ka huahana i hoʻāʻo ʻia ma ka X-Ray Test Record Form. E hoʻohui i nā kiʻi kūʻai ʻana o QFP a me QFN papa lepo, a mālama i 100% o nā kiʻi.

4. Inā loaʻa kekahi mau hemahema i ka wā o ka hoʻāʻo ʻana, pono e hōʻike koke ʻia i ka luna kiʻekiʻe a me ke kaʻina hana no ka hōʻoia ʻana.

ʻOihana X-ray Naʻauao Nānā Manaʻo

ʻO ka ʻōnaehana o nā lako X-RAY ka nui o ʻehiku mau ʻāpana: micro focus X-ray source, imaging unit, computer image processing system, mechanical system, electrical control system, safety protection system and warning system. Hoʻohui ia i ka hoʻāʻo hoʻopau ʻole, ʻenehana polokalamu kamepiula, kiʻi kiʻi & ʻenehana hana a me ka ʻenehana hoʻoili mīkini, e uhi ana i ʻehā mau ʻenehana nui o ka optical, mechanical, uila a me nā kiʻi kiʻi kiʻi. Ma o nā ʻokoʻa absorption o nā kukui X e nā mea like ʻole, kiʻi ʻia ke ʻano o loko o ka mea a lawe ʻia ka ʻike kīnā o loko. Hiki ke nānā ʻia ke kiʻi ʻike o ka huahana i ka manawa maoli e hoʻoholo ai inā he mau hemahema, nā ʻano kīnā a me nā pae maʻamau o ka ʻoihana i loko o ka huahana. Ma ka manawa like, hoʻohana ʻia ka ʻōnaehana kiʻi kiʻi kamepiula e mālama a hoʻoponopono i nā kiʻi e hoʻomaikaʻi ai i ka mālamalama o ke kiʻi a hōʻoia i ka pololei o ka loiloi. Hiki iā ia ke ana ʻakomi i nā ʻōhū ma nā ʻāpana uila i hoʻopaʻa ʻia e like me BGA a me QFN, a kākoʻo i nā ana geometric e like me ka mamao, ke kihi, ke anawaena, a me ka polygon. Hiki iā ia ke hoʻokō maʻalahi i ka ʻike hoʻonohonoho ʻana i nā helu he nui, e ʻae i nā huahana e haʻalele i ka hale hana me nā kīnā ʻole.
