Hariho ubwoko bwinshi bwa PCB binyuze mumyobo, kandi aperture zitandukanye zirashobora gutoranywa ukurikije ibisabwa bitandukanye nibisabwa. Ibikurikira bizasobanura neza aperture ya PCB isanzwe binyuze mumyobo no gutandukanya PCB binyuze mumyobo no mumyobo.
一 Ubwoko bwa aperture ya PCB binyuze mu mwobo
1. Aperture isanzwe (PCB Standard Hole): Mubisanzwe mubishushanyo bya PCB, umwobo uzenguruka ufite aperture irenze cyangwa ingana na 0.4mm yitwa aperture isanzwe. Iyi aperture ikoreshwa muburyo bwo kurinda umutekano wa PCB hamwe nibice pin ihuza.
2. Micro Hole aperture: Micro umwobo wa aperture bivuga umwobo uzenguruka ufite diameter iri munsi ya 0.4mm. Hamwe no kwiyongera kwa miniaturizasi yibikoresho bya elegitoronike, harakenewe cyane igishushanyo cya PCB, bityo micropore aperture igenda ikundwa buhoro buhoro. Gusaba microaperture harimo ibikoresho bya elegitoronike nka mudasobwa zigendanwa na terefone zigendanwa.
3. Urwobo rufunitse (Umuyoboro ucagaguye): umwobo wambuwe urudodo unyuze mu mwobo, ubusanzwe ukoreshwa mugushiraho ibice bifite intera ihujwe, nkibihuza cyangwa ibyuma bishyushya.
二 between itandukaniro riri hagati ya PCB unyuze mu mwobo no mu mwobo
PCB unyuze mu mwobo no mu mwobo biratandukanye mugukoresha ikibaho cya PCB, hariho itandukaniro rikurikira:
1. Intego ya PCB Intego: PCB ibyobo byabitswe nkana mubishushanyo, kandi bizatunganywa guhuza byibuze ibice bibiri bya PCB. Binyuze mu mwobo byashizweho kugirango uhuze urwego runaka cyangwa ibice, kandi aho biherereye bigenwa nibisabwa.
2, Guhuza Ibimenyetso (Guhuza Ibimenyetso): PCB unyuze mu mwobo ni ikimenyetso cyerekana kuva kumurongo umwe ujya kurundi rwego kugirango ugere ku kimenyetso. Binyuze mu mwobo bikoreshwa cyane cyane mugukosora imbaho za PCB nibigize no gutanga ubufasha bwubukanishi.
3. Uburyo bwo gukora: Ibyobo bya PCB bizavurwa nibikoresho byihariye nibikoresho mugihe cyo gukora, mubisanzwe hakoreshejwe amashanyarazi kugirango byongere amashanyarazi. Binyuze mu mwobo biroroshye, mubisanzwe bikenera gusa gutunganya umwobo mumwanya uhuye.
4. Inkunga yuburyo: Kubaho kwa PCB birashobora kongera imiterere yimiterere nubukomezi bwubuyobozi bwa PCB, kandi bigira uruhare runini. Nubwo unyuze mu mwobo ushobora kandi kongera urwego runaka rwo gukomera, intego nyamukuru ni ugutanga imirimo ihamye kandi ihujwe.
Muri make, aperture ya PCB ikoresheje umwobo irimo aperture isanzwe, microaperture nu mwobo. Itandukaniro riri hagati ya PCB rinyuze mu mwobo no mu mwobo rigaragarira cyane cyane mu gishushanyo mbonera, guhuza ibimenyetso, tekinoroji yo gutunganya no gushyigikira imiterere. Ibishushanyo bitandukanye bya PCB hamwe nibisabwa byo guterana birashobora kuzuzwa muguhitamo ubwoko butandukanye bwa aperture no gukoresha ibikwiye binyuze mumyobo cyangwa unyuze.
