Binyuze mu mwobo wa HDI PCB

Muburyo bwihuse bwa PCB igishushanyo, PCB igizwe cyane-kandi akenshi ikoresheje umwobo nikintu cyingenzi muburyo bwa PCB. Binyuze mu mwobo muri PCB bigizwe ahanini nibice bitatu: umwobo, gusudira agace kegereye umwobo hamwe n’ahantu hitaruye POWER. Ibikurikira, tuzasobanukirwa umuvuduko mwinshi PCB binyuze mubibazo byumwobo nibisabwa.

Ingaruka zinyuze mu mwobo muri HDI PCB

Muri platifike ya HDI PCB, guhuza imiyoboro hagati yikindi gice bigomba guhuzwa binyuze mu mwobo. Iyo inshuro ziri munsi ya 1 GHz, ibyobo birashobora kugira uruhare runini muguhuza, kandi ubushobozi bwa parasitike na inductance birashobora kwirengagizwa. Iyo inshuro irenze 1 GHz, ingaruka zingaruka za parasitike yumwobo urenze umwobo wibimenyetso ntishobora kwirengagizwa. Kuri iyi ngingo, umwobo urenze urugero werekana guhagarika inzitizi ku nzira yohereza, bizaganisha ku kwerekana ibimenyetso, gutinda, kwitabwaho hamwe n’ibindi bibazo byerekana ubunyangamugayo.

Iyo ikimenyetso cyoherejwe mu kindi gice kinyuze mu mwobo, umurongo werekana umurongo w'ikimenyetso nawo ukora nk'inzira yo kugaruka kw'ikimenyetso unyuze mu mwobo, kandi umuyoboro wo kugaruka uzatemba hagati y'ibice byerekanwe binyuze mu guhuza ubushobozi, bitera ibisasu ku butaka kandi ibindi bibazo.

Ubwoko bwa Nubwo-Hole, Mubisanzwe, binyuze mu mwobo bigabanijwemo ibyiciro bitatu: binyuze mu mwobo, umwobo uhumye hamwe nu mwobo washyinguwe.

Umwobo uhumye: umwobo uherereye hejuru no hepfo yububiko bwumuzingo wacapwe, ufite ubujyakuzimu runaka bwo guhuza umurongo wubuso n'umurongo w'imbere. Ubujyakuzimu bw'umwobo ntibushobora kurenza igipimo runaka cya aperture.

Umwobo washyinguwe: umwobo uhuza murwego rwimbere rwikibaho cyumuzingo cyacapwe kitaguka hejuru yubuyobozi bwumuzunguruko.

Binyuze mu mwobo: uyu mwobo unyura mu kibaho cyose cyumuzunguruko kandi urashobora gukoreshwa muguhuza imbere cyangwa nkumwobo ushyira ibice. Kuberako unyuze mu mwobo mubikorwa byoroshye kubigeraho, ikiguzi ni gito, mubisanzwe muri rusange icapiro ryumuzunguruko rikoreshwa

Binyuze mu mwobo muburyo bwihuse PCB

Mu buryo bwihuse bwa PCB igishushanyo, bisa nkaho byoroshye umwobo wa VIA uzazana ingaruka mbi cyane muburyo bwumuzunguruko.Mu rwego rwo kugabanya ingaruka mbi zatewe ningaruka za parasitike yo gutobora, dushobora kugerageza uko dushoboye:

. ubucucike PCB irashobora kandi gukoresha 0.20mm / 0.46mm / 0.86mm ikoresheje umwobo, irashobora kandi kugerageza itanyuze mu mwobo; Kubitanga amashanyarazi cyangwa umwobo winsinga wubutaka birashobora gufatwa nkugukoresha ubunini bunini kugirango ugabanye inzitizi;

(2) nini nini ya POWER yo kwigunga, nibyiza. Urebye ubucucike bwa PCB, muri rusange ni D1 = D2 + 0.41;

(3) gerageza udahindura urwego rwibimenyetso kuri PCB, nukuvuga, gerageza kugabanya umwobo;

(4) gukoresha PCB yoroheje bifasha kugabanya ibipimo bibiri bya parasitike unyuze mu mwobo;

(5) pin yo gutanga amashanyarazi nubutaka bugomba kuba hafi yumwobo. Mugihe kigufi kiyobora hagati yumwobo na pin, nibyiza, kuko bizatuma habaho kwiyongera kwa inductance.Mu gihe kimwe, amashanyarazi hamwe nubutaka bwubutaka bigomba kuba binini cyane kugirango bigabanye inzitizi;

.

Mubyongeyeho, binyuze muburebure bw'umwobo nabwo ni kimwe mu bintu by'ingenzi bigira ingaruka binyuze mu mwobo. Ku mwobo wo hejuru no hepfo, umwobo unyuramo uhwanye n'ubunini bwa PCB. Bitewe numubare wiyongera wa PCB, uburebure bwa PCB akenshi bugera kuri mm zirenga 5.

Nyamara, muburyo bwihuse bwa PCB PCB, kugirango ugabanye ikibazo cyatewe nu mwobo, uburebure bwumwobo bugenzurwa muri 2.0mm.Kuburebure bwumwobo burenze 2.0mm, gukomeza kwangirika kwumwobo birashobora kunozwa kuri bamwe urugero mu kongera umwobo wa diameter.Iyo uburebure bwanyuze mu mwobo ari 1.0mm no munsi, ibyiza byanyuze mu mwobo ni 0,20mm ~ 0,30mm.
