ʻO ke kaʻina hana hui BGA maʻamau e komo i kēia mau ʻanuʻu:
Hoʻomākaukau PCB: Hoʻomākaukau ʻia ka PCB ma ka hoʻopili ʻana i ka solder paste i nā pads kahi e kau ai ka BGA. ʻO ka solder paste he hui ia o nā ʻāpana solder alloy a me ka flux, e kōkua ana i ke kaʻina hana kūʻai.
Hoʻokomo ʻia nā BGA: ʻO nā BGA, ʻo ia ka puʻupuʻu kaapuni i hoʻohui ʻia me nā pōpō solder ma lalo, ua kau ʻia ma luna o ka PCB i hoʻomākaukau ʻia. Hana ʻia kēia me ka hoʻohana ʻana i nā mīkini koho-a-wahi a i ʻole nā mea hana ʻē aʻe.
Hoʻopili hou: ʻO ka PCB i hui pū ʻia me nā BGA i kau ʻia a laila hele ʻia i loko o kahi umu reflow. Hoʻomaʻamaʻa ka umu reflow i ka PCB i kahi mahana kikoʻī e hoʻoheheʻe ai i ka paʻi solder, e hoʻihoʻi hou i nā pōpō solder o nā BGA a hoʻokumu i nā pilina uila me nā pad PCB.
ʻO ka hoʻoluʻu a me ka nānā ʻana: Ma hope o ke kaʻina hana solder reflow, hoʻomaha ʻia ka PCB e hoʻopaʻa i nā hui solder. A laila nānā ʻia no nā hemahema, e like me ka misalignment, pōkole, a i ʻole nā pili wehe. Hiki ke hoʻohana ʻia ka nānā ʻana i ka ʻike maka (AOI) a i ʻole X-ray no kēia kumu.
Nā Kaʻina Hana ʻelua: Ma muli o nā koi kikoʻī, hiki ke hana ʻia nā kaʻina hana hou e like me ka hoʻomaʻemaʻe, hoʻāʻo, a me ka conformal coating ma hope o ka hui BGA e hōʻoia i ka hilinaʻi a me ka maikaʻi o ka huahana i hoʻopau ʻia.
