Via Ma Pad PCB

ʻO Via Ma Pad PCBʻano kālaihana , he poʻe hoʻolaleʻaleʻa mākou no China, Via Ma Pad PCB , 6Layer Via Ma Pad PCB mea kūʻai / halehanahana, nā huahanaʻano kiʻekiʻe o Pākaʻi Pāpā PC R & D a me nāʻoihana, ua loaʻa iā mākou kaʻoihana hope loa ma hope o ka kūʻaiʻana a me ke kākoʻo loea. E kakali i kāu hana!

'Oina Via Ma Pad PCB Nā mea hoʻolaha

Via ma Pad PCB
He aha ka Via i Pad? I ka manawa pōkole, ma ka pad, ʻo nā kahe ma ka SMD pad.An liʻiliʻi loa nā vias, ma lalo o ka 0.3mm.Wy pehea a pehea? ʻO ka mea mua, ʻaʻohe wahi e hoʻonohonoho pono ai iā ʻoe, pono ʻoe e kau i nā vias a me nā lua e kokoke kokoke a hui pū.
No ka mea, hele aku nā papa SMD no nā pahu SMD, no laila ʻaʻole hiki i ka mea kūʻai aku ke holo i ke kaena o loko a i ʻole ma nā ʻaoʻao ʻē aʻe i ka wā e hōʻuluʻulu ai.
Pehea nā mea hana PCB e like me mākou e hana ma ka papa papa? E hoʻopiha mākou i nā vias āpau me ka epoxy non-conductive a me ke keleawe keleawe ma luna o ia mea, no laila he pāleʻa nā vias me nā poʻe ʻē aʻe. ʻAʻole hiki i nā ʻoihana PCB nā hana i hiki ke hana like.
ʻO ke kīʻenehana nui pehea e hoʻopiha ai i nā vias a hōʻoiaʻiʻo inā ʻaʻohe mea kūʻai aku (ka hoʻopau ʻana ma luna o nā mea) i loko o nā lua.
ʻO ka hoʻopiha ʻia ma ka hoe ka ala kahi i hiki ai ke hoʻokō i ka lahilahi kikowaena me kahi kumukūʻai waena i hoʻohālikelike ʻia me ka hoʻohana ʻana i nā vias makapō. ʻO kekahi o nā pono kūpono e pili ana me ka hoʻohana ʻana i ka ma ka ʻenehana pad i:
.Fan i waho maikaʻi wili (ʻoi aku ma mua o ka .75mm) BGA
.Na mea i hoʻopili paʻa ʻia nā pono
.E hoʻokele wai wela
.Naʻikepili i nā pilikia hoʻolālā lahilahi kiʻekiʻe a me nā mea i koi ʻia ʻo
.I ʻole e hele a mālamalama i koi ʻia ma nā wahi wae
.Tuho i kahi mākaʻi, coplanar no ka hoʻopili ʻana
ʻAʻole nā ​​pilikia ma waena o nā pads nui, akā no BGA, ʻo ia ka ʻenehana.Aa liʻiliʻi nā pā paʻu BGA, 10mil a 12mil paha, ʻaʻohe wahi nui.Manufacturing ʻaʻole maʻalahi maʻalahi e like me nā papa ʻē aʻe.
