Binyuze mu mwobo wa HDI PCB

Mu buryo bwihuse PCB igishushanyo, PCB nyinshi zikoreshwa kenshi, kandi binyuze mu mwobo nikintu cyingenzi mubishushanyo byinshi bya PCB. Unyuze mu mwobo muri PCB ugizwe ahanini n'ibice bitatu: umwobo, gusudira agace ka padi ukikije umwobo n'imbaraga zo kwigunga. Ibikurikira, tuzumva umuvuduko mwinshi PCB binyuze mu mwobo hamwe nibisabwa.

Ingaruka zinyuze mu mwobo muri Hdi PCB

Muri HDI PCB Multilayer Centre, guhuza hagati yurwego rumwe nundi murwego rugomba guhuzwa binyuze mu mwobo. Iyo inshuro zitari munsi ya 1 ghz, ibyokurya birashobora kugira uruhare rwiza muguhuza, kandi ubushobozi bwa parasitike hamwe na gahunda birashobora kwirengagizwa. Iyo inshuro ziri hejuru ya 1 ghz, ingaruka zingaruka za parasitike zumwobo urenze ubunyangamugayo kugaragaza ntizishobora kwirengagizwa. Kuri iyi ngingo, umwobo urenze ugaragaza imiterere idahwitse ku nzira yo kohereza, izaganisha ku kwerekana ibimenyetso, gutinda, kwiteguza hamwe nibindi bibazo byuburiganya.

Iyo ikimenyetso cyoherezwa mubundi buryo unyuze mu mwobo, urwego rwerekana umurongo wibimenyetso ukoreramo ikimenyetso binyuze mu bushobozi bwonyine binyuze mu bushobozi bwonyine, bigatera ibisasu byonyine n'ibindi bibazo.

Ubwoko bwabwo nubwo bwose, muri rusange, binyuze mu mwobo bigabanyijemo ibyiciro bitatu: unyuze mu mwobo, umwobo uhumye kandi washyinguwe umwobo.

Umwobo uhumye: umwobo uherereye hejuru no hepfo yikibaho cyacapwe, ufite ubujyakuzimu bumwe bwo guhuza umurongo wumurongo nu murongo w'imbere. Ubujyakuzimu bwa umwobo mubisanzwe ntabwo burenze igipimo runaka cya aperture.

Umwobo washyinguwe: Umwobo uhuriro mumwanya w'imbere winama yumuriro wacapwe utaramuka hejuru yinama yumuzunguruko.

Unyuze mu mwobo: iyi mwobo inyura mu kigo cyose cy'umuzunguruko kandi irashobora gukoreshwa muguhuza imbere cyangwa nkimwobo uhuza ibice. Kuberako umwobo muburyo bworoshye kubigeraho, ikiguzi kiri hasi, muri rusange cyacapwe akanama gakoreshwa

Unyuze kuri umwobo mumuvuduko mwinshi PCB

Muburyo bwihuse PCB igishushanyo, bisa nkaho byoroshye ukoresheje umwobo akenshi uzana ingaruka mbi zifatika. Gutegeka kugabanya ingaruka mbi zatewe ningaruka za:

(1) Hitamo ubunini bwuzuye ingano nini yo kugabanya impetomu;

(2) nini nini yo kwigunga kwamashanyarazi, nibyiza. Urebye uko unyuze mu mwobo kuri PCB, muri rusange ni D1 = D2 + 0.41;

(3) Gerageza kudahindura igice cyikimenyetso kuri PCB, nukuvuga, gerageza kugabanya umwobo;

(4) Gukoresha PCB yoroheje ifasha kugabanya ibipimo bibiri bya parametike binyuze mu mwobo;

(5) PIN yimbaraga kandi ubutaka igomba kuba hafi yumwobo. Kugufi umurongo hagati yumwobo na pin, nibyiza, kuko bizatera kwiyongera kwatewe.at igihe kimwe, amashanyarazi nubutaka bugomba kuba binini kugirango bigabanye amakosa;

.

Byongeye kandi, binyuze mu burebure bw'uwo mucyo kandi ni kimwe mu bintu by'ingenzi bigira ingaruka ku mwobo. Kubwinjiriro bwo hejuru no hepfo Kubera umubare wiyongera kubice bya PCB, ubunini bwa PCB akenshi bugera kuri mm zirenga 5.

Ariko, muburyo bwihuse PCB igishushanyo mbonera, kugirango ugabanye ikibazo cyatewe numwobo, uburebure bwuzuye umwobo.
