Kūleʻa pinepine mākou i ka ilihune BGA soldering i ke kaʻina hana o ka PCB hui kaʻina ma muli o ka hoʻolālā PCB kūpono ʻole i ka hana.No laila, e hana ʻo PCBFuture i kahi hōʻuluʻulu a me ka hoʻolauna ʻana i kekahi mau hihia pilikia hoʻolālā maʻamau a ke manaʻo nei au hiki ke hāʻawi i nā manaʻo koʻikoʻi no nā mea hoʻolālā PCB!
Loaʻa ka nui o kēia mau hanana:
1. ʻAʻole hana ʻia nā vias lalo o ka BGA.
Aia nā puka ma ka BGA pad, a nalowale nā pōlele solder me ka solder i ke kaʻina hana kūʻai;ʻAʻole hoʻokō ka hana PCB i ke kaʻina hana solder mask, a ke kumu i ka nalo ʻana o nā pōpō solder a me nā pōpō solder ma o nā vias e pili ana i ka pad, ka hopena i ka nalowale ʻana o nā pōpō solder, e like me ka hōʻike ʻana ma ke kiʻi.
2.Hoʻolālā maikaʻi ʻia ka BGA solder mask.
ʻO ka hoʻokomo ʻana o nā puka ma nā pā PCB e hoʻopau i ka poho solder;Pono ka hui PCB kiʻekiʻe e hoʻohana i ka microvia, nā ala makapō a i ʻole nā kaʻina hana plugging e pale aku i ka nalowale o ka solder;E like me ka mea i hōʻike ʻia ma ke kiʻi aʻe, hoʻohana ia i ka soldering nalu, a aia nā vias ma lalo o ka BGA.Ma hope o ke kūʻai ʻana i ka nalu, pili ka solder ma nā vias i ka hilinaʻi o ka soldering BGA, e hoʻopilikia ai e like me nā pōkole pōkole o nā ʻāpana.
3. ʻO ka hoʻolālā BGA pad.
ʻAʻole pono ka uea alakaʻi o ka BGA pad ma mua o 50% o ke anawaena o ka pad, a ʻo ka uea alakaʻi o ka mana lako pad ʻaʻole pono e emi iho ma mua o 0.1mm, a laila mānoanoa.I mea e pale ai i ka deformation o ka pad, ʻaʻole ʻoi aku ka nui o ka puka aniani solder mask ma mua o 0.05mm, e like me ka mea i hōʻike ʻia ma ke kiʻi aʻe.
4.ʻAʻole i hoʻohālikelike ʻia ka nui o ka PCB BGA pad a he nui a liʻiliʻi paha, e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei.
5. He mau ʻokoʻa ka nui o nā pads BGA, a ʻo nā hui solder he mau pōʻai like ʻole o nā nui like ʻole, e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei.
6. Ua kokoke loa ka mamao ma waena o ka laina kiʻi BGA a me ka lihi o ke kino.
Pono nā ʻāpana a pau o nā ʻāpana i loko o ka hōʻailona hōʻailona, a ʻo ka mamao ma waena o ka laina kiʻi a me ka lihi o ka pūʻolo ʻāpana e ʻoi aku ma mua o 1/2 o ka nui o ka solder hope o ka mea, e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei.
ʻO PCBFuture kahi mea hana ʻoihana PCB & PCB hui e hiki ke hāʻawi me ka hana PCB, PCB hui a me nā lawelawe sourcing ʻāpana.ʻO ka ʻōnaehana hōʻoia maikaʻi maikaʻi loa a me nā mea nānā like ʻole e kōkua iā mākou e nānā i ke kaʻina hana holoʻokoʻa, hōʻoia i ka paʻa o kēia kaʻina hana a me ka maikaʻi o ka huahana kiʻekiʻe, ʻoiai, ua hoʻokomo ʻia nā mea hana kiʻekiʻe a me nā ʻano ʻenehana e loaʻa ai ka hoʻomaikaʻi mau.
