He aha te Huihuinga BGA?
Ko te huihuinga BGA e pā ana ki te tukanga o te whakairi i tētahi Pūrere Poroporo (BGA) ki runga i tētahi PCB mā te whakamahi i te tikanga whakapiringa whakawhiti. He wāhanga mata-mau te BGA e whakamahi ana i tētahi huinga pōro whakapiri hei hononga hiko. I te haerenga o te papa hiko mā roto i tētahi oumu whakapiringa whakawhiti, ka rewa ēnei pōro whakapiri, ka hanga hononga hiko.

Ngā Hipanga o te Huihuinga BGA
Ko te tukanga huihuinga BGA e whai ake nei:
Te Whakarite PCB: Ka whakaritea te PCB mā te tāpiri i te whakapiri konukōre ki ngā papa e whakanohoia ai te BGA. Ko te whakapiri konukōre he ranunga o ngā matūriki koranu konukōre me te rere, e āwhina ana i te tukanga konukōre.
Te Whakatakotoranga o ngā BGA: Ko ngā BGA, e titoa ana i te maramara ara iahiko whakauru me ngā pōro whakapiri i raro, ka whakatakotoria ki runga i te PCB kua whakaritea. Ko te tikanga ka mahia tēnei mā te whakamahi i ngā mīhini tango-me-te-whakatakotoranga aunoa, i ētahi atu taputapu huihuinga rānei.
Te Whakapiripiri Anō: Kātahi ka tukuna te PCB kua huihuia me ngā BGA kua whakanohoia mā roto i te oumu whakapiripiri. Ka whakamahanahia te PCB e te oumu whakapiripiri ki tētahi pāmahana motuhake e rewa ai te whakapiri whakapiri, ka meinga ngā pōro whakapiri o ngā BGA kia whakapiripiri, ka whakatū hononga hiko ki ngā papa PCB.
Te Whakamatao me te Tirotiro: Whai muri i te tukanga whakahou honohono, ka whakamataohia te PCB hei whakamātotoru i ngā hononga honohono. Kātahi ka tirotirohia mō ngā hapa, pērā i te he o te tūnga, ngā poto poto, ngā hononga tuwhera rānei. Ka taea te whakamahi i te tirotiro whatu aunoa (AOI) te tirotiro hihi-X rānei mō tēnei kaupapa.
Ngā Tukanga Tuarua: I runga anō i ngā whakaritenga motuhake, ka taea te whakahaere i ētahi atu tukanga pēnei i te horoi, te whakamātautau, me te paninga āhua rite i muri i te huihuinga BGA hei whakarite i te pono me te kounga o te hua kua oti.

1. He iti te tapuwae
Ko te takai BGA he maramara, he hononga, he papa angiangi, me te taupoki whakakī. He iti noa ngā wāhanga e kitea ana, ā, he iti noa ngā pine o te takai. Ko te teitei katoa o te maramara i runga i te PCB ka taea te iti iho i te 1.2 mirimita.
2. Te pakari
He tino pakari te takai BGA. Kāore i rite ki te QFP me te piko 20mil, kāore he pine o te BGA e piko, e whati rānei. I te nuinga o te wā, me whakamahi he teihana mahi anō BGA i ngā pāmahana teitei hei tango i te BGA.
3. Te iti o te ine me te kaha o te ine ira
He poto ngā pine me te iti o te teitei o te huihuinga, he iti te kaha hiko me te ine hiko o te takai BGA, ā, he pai rawa te mahi hiko.
4. Te whakanui ake i te wāhi rokiroki
Ki te whakaritea ki ētahi atu momo takai, kotahi hautoru noa iho o te rōrahi o te takai BGA, ā, tata ki te 1.2 ngā wā o te horahanga maramara. Ka taea e ngā hua mahara me ngā hua whakahaere e whakamahi ana i te takai BGA te whakatutuki i te pikinga neke atu i te 2.1 ngā wā o te kaha rokiroki me te tere whakahaere.
5. Te pumau teitei
Nā te toronga tika o ngā pine mai i waenganui o te maramara i roto i te takai BGA, ka whakapotohia ngā ara tuku mō ngā tohu rerekē, ka whakaiti i te whakaiti tohu, ka whakapai ake i te tere urupare me ngā āheinga ārai-whakararuraru. Ka whakarei ake tēnei i te pumau o te hua.
6. He pai te whakamararatanga wera
He tino pai te mahi a te BGA ki te tuku wera, me te pāmahana o te maramara e tata ana ki te pāmahana taiao i te wā e whakamahia ana.
7. He watea mō te mahi anō
Kei raro rawa ngā pine o te takai BGA, kia māmā ai te kimi i ngā wāhi kua pakaru hei tango. Mā tēnei ka māmā ake te mahi anō i ngā maramara BGA.
8. Te karo i te raruraru o ngā waea
Mā te takai BGA ka taea te whakanoho i ngā pine hiko me te pine whenua maha ki waenganui, me ngā pine I/O kei te taha. Ka taea te whakarite i mua i te ara i runga i te papa BGA, kia kore ai e pōrearea te waea o ngā pine I/O.
