He aha nā vias makapō a kanu ʻia?
Via makapō: Inā aia hoʻokahi ʻaoʻao o ka vias i ka papa waho o ka PCB, ua kapa ʻia lākou he vias makapō.
Ua kanu ʻia nā vias: Ke kanu ʻia nā ʻaoʻao ʻelua o nā vias i ka papa o loko o ka PCB, ua kapa ʻia lākou i kanu ʻia.
Pehea i hana ʻia ai nā vias makapō a kanu ʻia?
Hiki i nā ala ʻekolu ke hana i nā vias makapō a kanu ʻia:
ʻO ka wili mīkini me ka hohonu paʻa
Lamination a me ka wili ʻana
ʻO kēlā me kēia papa lamination a me ka wili ʻana
He aha ka makapō ma ke kaʻina hana?
ʻO ka mea mua, ke kamaʻilio nei mākou e pili ana i ka makapō laser drill ma o nā lua. PCB makapō ma ke kaʻina hana e like me kēia:
1) hoʻopau mua i nā papa o loko;
2) laminate i ʻelua papa o ka prepreg a me ka ʻāpana keleawe ma nā papa o loko o ka papa PCB i mākaukau;
3) e wili i ka makapō hohonu i hoʻomalu ʻia ma ka PCB e ka laser.
E ʻoluʻolu, he mea nui ka pololei no ka poʻe makapō ma ka papa.
No ka mechanical drill makapō ma nā puka, lawe mākou i nā PCB 4-layer me nā vias makapō ma ka papa 1 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-layer maʻamau, no laila e loaʻa nā drills ma nā papa 1 a 2;
2) laminate i ʻelua papa kumu i loaʻa iā mākou ka 4-layer PCB, a wili i ka plating ma nā lua;
3) i ka pau ʻana o ka PCB, loaʻa iā ʻoe ka PTH mai nā papa 1 a i 4 a me nā vias makapō mai nā papa 1 a i 2.
He aha nā pōmaikaʻi o ka hoʻohana ʻana i nā vias makapō a kanu ʻia?
ʻO nā pōmaikaʻi o ka hoʻohana ʻana i ka makapō a kanu ʻia ma lalo nei:
Hoʻemi i ka nui a me ke kaumaha o ka PCB
E hoemi ana i ka nui o na papa
Hoʻemi i nā kumukūʻai o ka hana ʻana o nā ʻano PCB mai ka hui ʻana i nā hana hou aku
Hoʻomaikaʻi i ka hoʻohālikelike electromagnetic
Hoʻonui i nā hiʻohiʻona 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 anawaena o nā makapō a kanu ʻia i nā koi kiʻekiʻe ma ka hana PCB.
Pono nā ʻenehana loea loa e hoʻolālā i nā makapō a kanu ʻia ma o PCBs.
ʻOi aku ka paʻakikī o ka hōʻuluʻulu ʻana i nā makapō a kanu ʻia ma o PCB no ka mea he mau pā liʻiliʻi lākou, e like me nā pad BGA.
He aha ka makapō maʻamau ma o ka lākiō hiʻohiʻona?
I ka laser drill blind vias board, ʻo ka makapō maʻamau ma o ka ratio hiʻohiʻona he 1:1.
He aha ke kanu ʻia ma o?
Ua kanu ʻia nā vias ma PCB ma nā lua ma waena o nā papa o loko. Lawe mākou i kahi 6 papa makapō / kanu ʻia ma o ka papa kaapuni no ka laʻana: hiki i nā makapō ma nā puka mai ka papa 2-3, 2-4, 2-5, 3-4, 3-5 a me 4-5.
Kanu ma vs makapo ma
ʻO nā makapō ma o a kanu ʻia ma ka hoʻohana mau ʻia ʻo HDI PCBs, aia mau lākou i nā papa kaapuni kiʻekiʻe kiʻekiʻe kiʻekiʻe i ka manawa like. Akā he ʻano like ʻole lākou o nā vias.
