He aha nā vias makapō a me nā vias i kanu ʻia?
Nā vias makapō: Ke hoʻokahi wale nō ʻaoʻao o nā vias i loko o ka papa waho o ka PCB, ua kapa ʻia lākou he vias makapō.
Nā vias i kanu ʻia: Ke kanu ʻia nā ʻaoʻao ʻelua o nā vias i loko o ka papa o loko o ka PCB, ua kapa ʻia lākou he vias i kanu ʻia.
Pehea e hana ʻia ai nā vias makapō a me nā vias i kanu ʻia?
Hiki i nā ʻano hana ʻekolu ke hana i nā vias makapō a kanu ʻia:
ʻEli mīkini me ka hohonu paʻa
Ka lamination a me ka ʻeli ʻana i ka hopena
ʻO kēlā me kēia papa lamination a me ka ʻeli ʻana
He aha ka makapō ma o ke kaʻina hana?
ʻO ka mea mua, kamaʻilio mākou e pili ana i ka makapō wili laser ma o nā lua. Makapō PCB ma o ke kaʻina hana hana e like me kēia:
1) e hoʻopau mua i nā papa o loko a pau;
2) e hoʻopaʻa i ʻelua papa o ka pepa prepreg a me ke keleawe ma nā papa o loko o ka papa PCB i hoʻopau mua ʻia;
3) e wili i ka makapō hohonu i kāohi ʻia ma o ka PCB e ka laser.
E ʻoluʻolu e hoʻomaopopo he mea nui loa ka pololei no ka makapō ma o ka pad.
No ka mīkini wili makapō ma o nā lua, lawe mākou i nā PCB 4-papa me nā vias makapō ma ka papa 1 a i ka papa 2 no ka laʻana, ke kaʻina hana penei:
1) hana i nā papa 1 a me 2 ma ke ʻano he PCB 2-papa maʻamau, no laila e loaʻa nā wili ma nā papa 1 a 2;
2) e hoʻohui i ʻelua papa koʻikoʻi i loaʻa iā mākou ka PCB 4-layer, a wili i ka plating ma o nā lua;
3) ke pau ka PCB, loaʻa iā ʻoe ka PTH mai nā papa 1 a 4 a me nā vias makapō mai nā papa 1 a 2.
He aha nā pōmaikaʻi o ka hoʻohana ʻana i nā vias makapō a kanu ʻia?
Aia ma lalo nā pōmaikaʻi o ka hoʻohana ʻana i ka makapō a me ke kanu ʻia:
Hoʻemi i ka nui a me ke kaumaha o ka PCB
Hoʻemi ʻana i ka helu o nā papa
Hoʻemi i nā kumukūʻai o ka hana ʻana o kekahi mau ʻano PCB mai ka hoʻohui ʻana i nā hana hou aʻe
Ka hoʻomaikaʻi ʻana i ka hoʻohālikelike electromagnetic
Hoʻonui i nā ʻano o nā huahana uila
E maʻalahi a wikiwiki hoʻi ka hana hoʻolālā
He aha nā pilikia o ka hoʻohana ʻana i nā vias makapō a kanu ʻia?
ʻO ka miniaturization o nā diameters o nā vias makapō a kanu ʻia e kau i nā koi kiʻekiʻe ma ka hana PCB.
Pono nā ʻenekinia ʻike nui loa e hoʻolālā i nā PCB vias makapō a kanu ʻia.
He mea paʻakikī ke hōʻuluʻulu i nā PCB vias makapō a kanu ʻia no ka mea he mau pads liʻiliʻi ko lākou, e like me nā pads BGA.
He aha ka lakio hiʻohiʻona maʻamau o ka makapō ma o ka makapō?
I ka papa vias blind drill laser, ʻo ka lakio hiʻohiʻona via blind maʻamau he 1:1.
He aha ka mea i kanu ʻia ma o?
ʻO nā vias i kanu ʻia i loko o ka PCB ma o nā lua ma waena o nā papa o loko. Lawe mākou i kahi makapō 6 papa/i kanu ʻia ma o ka papa kaapuni no ka laʻana: hiki i nā vias makapō ke ma o nā lua mai ka papa 2-3, 2-4, 2-5, 3-4, 3-5 a me 4-5.
Kanu ʻia ma o vs makapō ma o
ʻO Blind via a me buried via nā PCB HDI i hoʻohana pinepine ʻia, aia mau lākou i nā papa kaapuni paʻi kiʻekiʻe ʻenehana kiʻekiʻe i ka manawa like. Akā he ʻano like ʻole lākou o nā vias.
