Viya ni impumyi kandi yashyinguwe ni iki?
Impumyi zimpumyi: Iyo uruhande rumwe gusa rwa vias ruri murwego rwinyuma rwa PCB, bita vias impumyi.
Viyasi yashyinguwe: Iyo impande zombi za vias zishyinguwe murwego rwimbere rwa PCB, zitwa vi zashyinguwe.
Nigute impumyi zishyinguwe zashyinguwe?
Uburyo butatu bukurikira burashobora gukora impumyi kandi zishyinguwe:
Gucukura imashini hamwe nubujyakuzimu
Gukurikirana no gucukura
Igice cyose cyo kumurika no gucukura
Niki gihumye binyuze mubikorwa byo gukora?
Ubwa mbere, tuvuga kuri laser drill impumyi ikoresheje umwobo. PCB impumyi ikoresheje inzira yo guhimba nkibi bikurikira:
1) kurangiza ibice byose byimbere;
)
3) gucukura ubujyakuzimu bugenzurwa ukoresheje PCB ukoresheje laser.
Nyamuneka menya neza ko impamo ari ingenzi cyane kubatabona binyuze muri padi.
Kubijyanye na mashini ya drine impumyi ikoresheje umwobo, dufata PCB-4-ya PCB hamwe na vias ihumye murwego rwa 1 kugeza kuri 2 urugero, inzira ikurikira:
1) kubyara ibice 1 na 2 nkibisanzwe 2-layer PCB, bityo hazabaho imyitozo kumurongo 1 kugeza 2;
2) kumanika imbaho ebyiri zingenzi hamwe kugirango tubone PCB-4, hanyuma ducukure isahani mu mwobo;
3) iyo PCB irangiye, ubona PTH kuva kumurongo 1 kugeza 4 na vias zihumye kuva kumurongo 1 kugeza 2.
Ni izihe nyungu zo gukoresha vias zihumye kandi zishyinguwe?
Ibyiza byo gukoresha impumyi no gushyingurwa byavuzwe hepfo:
Kugabanya ingano n'uburemere bwa PCB
Kugabanya umubare wibice
Kugabanya ibiciro byumusaruro wubwoko butandukanye bwa PCB kuva uhuza imirimo myinshi
Kunoza guhuza amashanyarazi
Kongera ibiranga ibicuruzwa bya elegitoroniki
Gukora igishushanyo mbonera cyoroshye kandi vuba
Ni izihe mbogamizi zo gukoresha viasi zihumye kandi zishyinguwe?
Miniaturisiyasi ya diametre yimpumyi zishyinguwe kandi zishyinguwe zishyira hejuru cyane umusaruro wa PCB.
Ba injeniyeri b'inararibonye cyane barakenewe gushushanya impumyi kandi zishyinguwe PCBs.
Biragoye cyane guteranya impumyi kandi zishyinguwe na PCBs kuko burigihe zifite udupapuro duto, nka BGA.
Nimpumyi zisanzwe nizihe zingana?
Muri laser drill impumyi vias ikibaho, impumyi isanzwe ikoresheje igereranyo ni 1: 1.
Ni iki gihambwa binyuze?
Gushyingura vias muri PCB binyuze mumyobo hagati yimbere. Dufata ibice 6 impumyi / yashyinguwe dukoresheje ikibaho cyumuzunguruko urugero: vias ihumye irashobora kunyura mumyobo kuva kumurongo 2-3, 2-4, 2-5, 3-4, 3-5 na 4-5.
Yahambwe binyuze kuri vs impumyi binyuze
Impumyi zinyuze kandi zishyinguwe zikoreshwa mubisanzwe HDI PCBs, zihora zibaho mubuhanga buhanitse bwo hejuru cyane bwanditseho imbaho zumuzingo icyarimwe. Ariko ni ubwoko butandukanye rwose.
