He aha ngā via matapo me ngā via tanumia?
Ngā via matapo: Ina kotahi anake te taha o ngā via kei roto i te paparanga o waho o te PCB, ka kiia ēnei he via matapo.
Ngā via tanumia: Ina tanumia ngā taha e rua o ngā via ki te paparanga o roto o te PCB, ka kiia rātou he via tanumia.
Me pēhea te hanga i ngā vias matapo me ngā vias tanumia?
Mā ngā tikanga e toru e whai ake nei ka taea te hanga i ngā vias matapo me ngā vias tanumia:
Te keri miihini me te hohonu pumau
Te whakarārangi me te keri raupapa
Te whakarārangi me te keri i tetahi paparanga
He aha te matapo i roto i te tukanga hangahanga?
Tuatahi, ka kōrero tātou mō te arai wiri taiaho mā roto i ngā kōhao. Ko te tukanga hanga arai PCB mā roto i te tukanga e whai ake nei:
1) whakaotia ngā paparanga o roto katoa i te tuatahi;
2) pania kia rua ngā paparanga o te pepa parahi me te pepa i mua i te paninga ki runga i ngā paparanga o roto o te papa PCB kua oti te whakaoti;
3) pokaia te matapo hohonu e whakahaeretia ana mā te PCB mā te whakamahi i te laser.
Kia mōhio koe he mea tino nui te tika mō te papa matapo mā roto.
Mō ngā arai wiri miihini mā roto i ngā kōhao, ka tangohia e mātou ngā PCB paparanga-4 me ngā arai matapo i te paparanga 1 ki te paparanga 2 hei tauira, ko te tukanga penei:
1) whakaputa i ngā paparanga 1 me te 2 hei PCB paparanga-2 paerewa, nō reira ka whai pokaia ngā paparanga 1 ki te 2;
2) whakapirihia ngā papa matua e rua kia honoa kia puta ai te PCB paparanga-whā, ā, ka pokaia te whakakikorua mā roto i ngā kōhao;
3) ina oti te PCB, ka whiwhi koe i te PTH mai i ngā paparanga 1 ki te 4 me ngā via matapo mai i ngā paparanga 1 ki te 2.
He aha ngā painga o te whakamahi i ngā via matapo me ngā via tanumia?
Ko ngā painga o te whakamahi i ngā matapo me ngā mea huna e whakahuatia ana i raro nei:
Te whakaiti i te rahi me te taumaha o te PCB
Te whakaiti i te maha o ngā paparanga
Te whakaiti i ngā utu o te hanga i ētahi momo PCB nā te whakakotahi i ngā mahi maha atu
Te whakapai ake i te hototahitanga hikohiko
Te whakanui ake i ngā āhuatanga o ngā hua hiko
Kia māmā ake, kia tere ake hoki te mahi hoahoa
He aha ngā wero o te whakamahi i ngā vias matapo me ngā vias tanumia?
Ko te whakaiti i te diameter o ngā via matapo me ngā via tanumia ka nui ake te tono mō te hanga PCB.
E hiahiatia ana ngā kaihangarau tino mātau ki te hoahoa i ngā PCB vias matapo me ngā PCB vias tanumia.
He uaua ake te huihui i ngā PCB vias matapo me ngā PCB vias tanumia nā te mea he iti noa ngā papa i roto, pērā i ngā papa BGA.
He aha te ōwehenga āhua matapo noa?
I roto i te papa arai wiri taiaho, ko te ōwehenga āhua arai noa he 1:1.
Mā te aha ka tanumia ai?
Ko ngā vias tanumia i roto i te PCB he mea mā roto i ngā kōhao i waenganui i ngā paparanga o roto. Hei tauira, ka tangohia he matapo paparanga e 6/he papa hiko tanumia: ka taea e ngā vias matapo te mā roto i ngā kōhao mai i te paparanga 2-3, 2-4, 2-5, 3-4, 3-5 me te 4-5.
I tanumia mā te matapo, me te matapo mā te
Ko te Blind via me te buried via he PCB HDI e whakamahia whānuitia ana, kei roto tonu i ngā papa hiko tānga hangarau-teitei i te wā kotahi. Engari he momo rerekē rawa atu ēnei o te via.
