Bitewe no guhinduranya ibintu biranga amashanyarazi, biroroshye gutera amashanyarazi kugirango atange amashanyarazi akomeye. Nka injeniyeri itanga amashanyarazi, injeniyeri ya electromagnetic ihuza injeniyeri, cyangwa injeniyeri ya PCB, ugomba gusobanukirwa nimpamvu zitera ibibazo byo guhuza amashanyarazi kandi ukemura ingamba, cyane cyane imiterere Abashakashatsi bakeneye kumenya uburyo bwo kwirinda kwaguka kwanduye. Iyi ngingo irerekana cyane cyane ingingo zingenzi zo gutanga amashanyarazi igishushanyo cya PCB.

1. Amahame menshi yibanze: insinga iyo ari yo yose ifite inzitizi; ikigezweho burigihe ihita ihitamo inzira hamwe na impedance nkeya; ubukana bwimirasire bujyanye nubu, inshuro, hamwe nu gace ka loop; uburyo busanzwe bwo kwivanga bufitanye isano na capacitance ya signal nini ya dv / dt kubutaka; Ihame ryo kugabanya EMI no kongera ubushobozi bwo kurwanya interineti birasa.

2. Imiterere igomba kugabanywa ukurikije amashanyarazi, analog, yihuta ya digitale na buri gice gikora.

3. Kugabanya ubuso bunini bwa di / dt hanyuma ugabanye uburebure (cyangwa agace, ubugari bwumurongo munini wa dv / dt). Ubwiyongere bwakarere ka trike buzongera ubushobozi bwagabanijwe. Inzira rusange ni: ubugari bwikigereranyo Gerageza kuba nini ishoboka, ariko ukureho igice kirenze), hanyuma ugerageze kugendera kumurongo ugororotse kugirango ugabanye ahantu hihishe kugirango ugabanye imirasire.

4. Kwambukiranya Inductive biterwa ahanini na di / dt nini (loop antenna), kandi ubukana bwa induction buragereranywa no kwishyira hamwe, bityo rero ni ngombwa cyane kugabanya inductance hagati yibi bimenyetso (inzira nyamukuru ni ukugabanya agace kazunguruka no kongera intera); Imibonano mpuzabitsina ikorwa ahanini nibimenyetso binini bya dv / dt, kandi ubukana bwa induction buragereranywa nubushobozi bwa mutuelle. Ubushobozi bwose bwa mutuelle hamwe nibi bimenyetso buragabanuka (inzira nyamukuru nukugabanya ahantu heza ho guhurira no kongera intera. Ubushobozi bwa mutuelle buragabanuka hamwe no kwiyongera kwintera. Byihuse) birakomeye.

5. Gerageza gukoresha ihame ryo guhagarika loop kugirango urusheho kugabanya ubuso bunini bwa di / dt, nkuko bigaragara ku gishushanyo 1 (bisa na couple ihindagurika
Koresha ihame ryo guhagarika loop kugirango utezimbere ubushobozi bwo kurwanya interineti no kongera intera yoherejwe):

Igishushanyo 1, Gusiba gukuraho (loopweling loop of boost circuit)

6. Kugabanya agace kazengurutse ntibigabanya imirasire gusa, ahubwo binagabanya inductance ya loop, bigatuma imikorere yumuzunguruko iba myiza.

7. Kugabanya agace ka loop biradusaba gushushanya neza inzira yo kugaruka ya buri murongo.

8. Iyo PCB nyinshi zahujwe hakoreshejwe umuhuza, birakenewe kandi gutekereza kugabanya agace kazengurutse, cyane cyane kubimenyetso binini bya di / dt, ibimenyetso byinshyi nyinshi cyangwa ibimenyetso byoroshye. Nibyiza ko insinga imwe yikimenyetso ihuye numuyoboro umwe wubutaka, kandi insinga zombi zegeranye bishoboka. Nibiba ngombwa, insinga zombi zigoramye zirashobora gukoreshwa muguhuza (uburebure bwa buri cyuma cyerekejwe hamwe gihuye numubare wuzuye wurusaku igice-cyumurambararo). Niba ufunguye dosiye ya mudasobwa, urashobora kubona ko USB ya interineti hagati ya kibaho na panne yimbere ihujwe na joriji ihindagurika, yerekana akamaro ko guhuza ibice byombi bigamije kurwanya no kugabanya imirasire.

9. Kubisobanuro byamakuru, gerageza gutondekanya insinga nyinshi zubutaka muri kabel, hanyuma utume izo nsinga zubutaka zigabanywa neza muri kabili, zishobora kugabanya neza agace kegeranye.

10. Nubwo imirongo imwe ihuza imiyoboro ari ibimenyetso byumuvuduko muke, kubera ko ibyo bimenyetso bito bikubiyemo urusaku rwinshi rwinshi (binyuze mumiyoboro n'imirasire), biroroshye gusakuza ayo majwi niba bidakozwe neza.

11. Mugihe wiring, banza usuzume ibimenyetso binini bigezweho hamwe nibisobanuro bikunda kurasa.

12. Guhindura ibikoresho byamashanyarazi mubisanzwe bifite imirongo 4 igezweho: ibyinjijwe, ibisohoka, guhinduranya, kwidegembya, (Ishusho 2). Muri byo, ibyinjijwe nibisohoka bizenguruka hafi ya byose, hafi nta emi yabyaye, ariko birahungabana byoroshye; guhinduranya no kwidagadura byubu bifite di / dt nini, ikeneye kwitabwaho.
Igishushanyo 2, Ikizunguruka cyubu cyumuzunguruko

13. Inzira yo gutwara amarembo ya mos (igbt) mubusanzwe nayo irimo di / dt nini.

14. Ntugashyireho utumenyetso duto duto, nko kugenzura no kugereranya ibintu, imbere nini nini, umuvuduko mwinshi hamwe n’umuriro mwinshi kugirango wirinde kwivanga.
