Ihame rya Wiring rya PCB ibice bibiri

PCB nikintu cyingenzi cya elegitoroniki ninkomoko yibikoresho byose bya elegitoroniki.Byarushijeho kuba ingorabahizi kuva byagaragaye mwisi yanyuma.Kuva kumurongo umwe kugeza kumurongo ibiri, enye-enye, hanyuma ukagera kuri byinshi, igishushanyo mbonera nacyo kiriyongera.binini.Hano hari insinga kumpande zombi, zidufasha cyane gusobanukirwa no kumenya ihame ryayo.Reka turebe ihame rya wiring ya PCB ya kabiri.

Ububiko bubiri bwa PCB bwashizweho muburyo bwuruzitiro ruzengurutse agasanduku, ni ukuvuga, uruhande rwa PCB rusa cyane nubutaka, naho kurundi ruhande ni ikibaho cya kopi yubutaka, hanyuma bigahuzwa. hamwe na vias metallised (unyuze mu mwobo ni muto).

Urebye ko hagomba kubaho insinga zubutaka hafi ya buri chip ya IC, mubisanzwe insinga yubutaka ikorwa buri 1 ~ 115cm, bizatuma agace kerekana ibimenyetso bito kandi bifasha kugabanya imirasire.Uburyo bwo gushushanya imiyoboro igomba kuba mbere yumurongo wibimenyetso, bitabaye ibyo kuyishyira mubikorwa biragoye.

Ihame ryerekana ibimenyetso:

Nyuma yimiterere yimiterere yibigize igenwa, hagakurikiraho ikibaho cyikubye kabiri, hanyuma igishushanyo mbonera cyikingira hasi, hanyuma insinga zingenzi (insinga zoroshye, insinga nini cyane hamwe ninsinga zisanzwe inyuma).Intsinga zikomeye zigomba kugira imbaraga zitandukanye, kugaruka kubutaka, insinga na bigufi cyane, kuburyo rimwe na rimwe ubutaka hafi yinsinga zikomeye zegeranye ninsinga zerekana ibimenyetso kugirango habeho uruziga ruto.

Ikibaho cyibice bine gifite ubuso bubiri hejuru, naho hepfo yikibaho ni umurongo wibimenyetso.Mbere ya byose, urufunguzo rwa kirisiti, uruziga rwa kristu, uruziga rw'isaha, umurongo w'ikimenyetso hamwe na CPU bigomba kubahiriza ihame ryahantu hato hashoboka.

Iyo icapiro rya plaque ya IC ikora, agace kazenguruka kavuzwe inshuro nyinshi, mubyukuri nicyo gitekerezo cyimirasire itandukanye.Nkibisobanuro byimirasire yuburyo butandukanye: uruziga rukora ibintu bitembera mumuzunguruko wa signal, hamwe na signal ya signal izabyara imirasire ya electromagnetique, iterwa nuburyo butandukanye, bityo rero uburyo bwo gutandukanya ibimenyetso byerekana ko butangwa nimirasire. imirasire, nuburemere bwumurima wumurishyo Imibare yo kubara ni: E1 = K1, f2, ia / gamma

Ubwoko: E1 - uburyo butandukanye bwo gukoporora ikibaho, imbaraga za gamma imirasire yumwanya wumurongo wumurongo wa PCB urashobora kuboneka ukoresheje uburyo butandukanye bwimirasire yimirasire, imbaraga zumurishyo zingana na fonctionnement ya f2, Agace kazenguruka, hamwe nubu bukora, I nkigihe cyo kumenya akazi Inshuro f nubunini bwahantu hatemba nibintu byingenzi dushobora kugenzura mubishushanyo mbonera.Mugihe kimwe, mugihe cyose akazi gatemba gahuye nubwizerwe, umuvuduko, nubu, nini nini nziza, gukubitwa gukubitwa kumpande yikimenyetso, binini bigize ibice bihuza, binini cyane, niko amashanyarazi arushaho kuba menshi. imirasire, igomba kwerekanwa (hejuru) imbaraga nyinshi zubu, ibyo tudashaka.

Niba bishoboka, uzenguruke amasano akomeye hamwe ninsinga.Iyo uhinduranya ikopi ya PCB nyuma yizindi, insinga zubutaka zihari zitwikiriye icyuho cyose, ariko hagomba kwitonderwa kuri izo nsinga zose zubutaka, ikibanza kizaba kigizwe ningufi nini nini ntoya, ishobora kugera kubisubizo byiza (Icyitonderwa: Hano haribisabwa umwanya ugomba kuba wujuje ibisabwa, nkintera ya creepage).
