Ibintu bitatu byo kurinda ubunyangamugayo muriPCB Gushushanya

Mu gishushanyo cya elegitoroniki kigezweho, ubunyangamugayo bwamashanyarazi ni igice cyingenzi cyigishushanyo cya PCB. Kugirango tumenye neza ibikorwa bihamye nibikorwa bya elegitoroniki, tugomba gusuzuma no gushushanya ku buryo buturutse ku isoko ifatiko.

Binyuze mugutegura witonze kandi ukunda amashanyarazi, indege yimbere, hamwe na chip yo gutanga amashanyarazi dushobora kugera kubunyangamugayo. Iyi ngingo izacengera muri izi ngingo eshatu zo gutanga ubuyobozi ningamba zifatika kubashushanya PCB.

I. Imbaraga Module Moyout

Module yububasha nisoko yingufu za buri shusho ya elegitoronike, imikorere yayo n'imiterere bigira ingaruka muburyo butuje kandi bukora neza. Imiterere hamwe ninzira nyabagendwa ntibishobora kugabanya gusa urusaku gusa ahubwo komeza ko uterera imbere, bityo utezimbere imikorere rusange.

2.Kwiza Module

1.Ibyo gutunganya:

Module yububasha igomba kwitabwaho bidasanzwe kuko ikora nkibihe byimbaraga. Kugabanya urusaku, ibidukikije bikikije Module bigomba kuguma isuku bishoboka kugirango wirinde kwegeranya undiinshuro nyinshicyangwa urusaku rwimiti.

2.Gukora kuri Chip Amashanyarazi:

Module yububasha igomba gushyirwa hafi ya chip itangwa imbaraga. Ibi birashobora kugabanya igihombo muburyo bwo kohereza no kugabanya ibisabwa mu ndege yimbere.

3.Ibitekerezo byo gutandukana:

Module yububasha irashobora kubyara ubushyuhe mugihe cyo gukora, niko bigomba kwemerwa ko nta moko iri hejuru yo gutandukana nubushyuhe. Nibiba ngombwa, ubushyuhe cyangwa abafana barashobora kongerwaho kugirango bakonje.

4.Ibanga ryings:

Iyo inzira, irinde gukora imirongo iriho kugirango ugabanye amahirwe yo kwivanga electonagnetic.

II. Igenamigambi ry'indege

A. Igishushanyo mbonera

In PCB EMC Igishushanyo, igishushanyo mbonera cyibice nikintu cyingenzi gikeneye gusuzuma inzira no kugabura amashanyarazi.

a. Kugirango umenye imiterere ihindagurika ryindege no gukuramo urusaku rwinshi, intera iri hagati yubutaka nubutaka ntigomba kurenza 10mil, mubisanzwe bisabwa kuba munsi ya 5mil.

b. Niba indege imwe indege idashobora gushyirwa mubikorwa, urwego rwo hejuru rushobora gukoreshwa mugusohora indege yamashanyarazi. Imbaraga zegeranye nubutaka hafi yubutaka zigize ubushobozi bwindege hamwe na AC Impence hamwe nintangarugero nziza.

c. Irinde kwegeranya amashanyarazi abiri, cyane cyane hamwe nitandukaniro rinini voltage, gukumira urusaku. Niba udashobora kwirindwa, ongera urugero hagati yububasha bubiri bushoboka.

d. Indege, cyane cyane indege zerekana indege, zigomba gukomeza ibiranga bidafite imbaraga kandi birashobora guteganya binyuze mu kwangwa na ofpasse hamwe nibisobanuro.

B.Multiple Seogration Seogramion

a. Kuburyo butandukanye bwamashanyarazi, nka voltage yibanze ya chip imwe, umuringa ugomba gushyirwaho ikimenyetso cyindege kugirango wirinde indege yingufu, ahubwo wirinde gushyira umuringa wumuringa hejuru kugirango ugabanye imirasire yubuso.

b. Guhitamo ubugari bwo gutandukanya bukwiye. Iyo voltage iruta 12v, ubugari bushobora kuba 20-30mil; Bitabaye ibyo, hitamo 12-20mil. Ubugari bwa Digmentation hagati yingufu na digitale bigomba kwiyongera kugirango birinde imbaraga za digitale kubangamira imbaraga za Analog.

c. Imiyoboro yoroshye imbaraga zigomba kurangira kumurongo wa routiuut, kandi imiyoboro mikuruzi zubutegetsi igomba kuba ifite akayunguruzo yongeyeho.

d. Indege yatewe indege igomba kubikwa buri gihe kwirinda imiterere idasanzwe itera imbaraga no kongera imbaraga. Ibice birebire kandi bigufi hamwe n'amacakubiri ameze nk'ibitunze ntabwo byemewe.

c.iplane

a. Indege y'amashanyarazi igomba guhuzwa cyane nindege yubutaka.

b. Kuri chip hamwe na metero zikora 500mhz, mbere na mbere zishingiye kumikoreshereze yindege iyungurura no gukoresha ihuriro rya capactor. Ingaruka yo gushungura igomba kwemezwa nubunyangamugayo bwo kwigana.

c. Shyira Indumimari kugirango utere imbaraga mu ndege igenzura, nko kwagura ubushobozi biganisha no kongera ubushobozi dias, kugirango umenye neza ko impengane y'ubutaka iri munsi yintego.

III. Power Chip Imiterere

Chip Imbaraga nibanze yibikoresho bya elegitoronike, kandi ukemure inyangamugayo zayo ni ngombwa kugirango utezimbere imikorere yimikorere no gutuza. Ubunyangamugayo bwo kugenzura imitwe yububasha ahanini bikubiyemo kwikuramo imiyoboro ya chip amakaramu no gukosora imiterere no gushaka ubushobozi bwo guta agaciro. Ibikurikira bizaramburwa ibitekerezo ninama zifatika zerekeye izi ngingo.

Igisubizo.

Inzira ya Chip Peins nigice cyingenzi cyubunyangamugayo. Kugira ngo utange isoko rihamye, zisabwa guhunika inzira y'amavuko, muri rusange ku bugari bumwe nk'imikino ya chip. Mubisanzwe, theUbugari ntarengwantigomba kuba munsi ya 8mil, ahubwo ni ibisubizo byiza, gerageza kugera kubugari bwa 10mil. Mu kongera ubugari bwinzira, imbaraga zirashobora kugabanuka, bityo bikagabanya urusaku rwimbaraga no guharanira kopi zihagije kuri chip.

B.uwagukaga no kugabura ubushobozi bwo gutesha agaciro

Gukoresha decouplingrs bigira uruhare runini mubunyangamugayo bugenzura amashanyarazi. Ukurikije ubushobozi buranga no gusaba ibisabwa, ubushobozi bwo gutesha agaciro muri rusange bugabanijwemo ubwanyo nini kandi nto.

a. Ubushobozi bunini: Ubushobozi bunini burakwirakwizwa hafi ya chip. Bitewe na resonant yabo yoroheje hamwe na radiyo nini yo kuyungurura radiyo, irashobora kuyungurura neza urusaku ruto kandi rutanga amashanyarazi ahamye.

b. Cangerters nto: ubushobozi buto bufite inshuro zidasanzwe hamwe na radiyo ntoya yo kuyungurura, bityo bigomba gushyirwa hafi bishoboka mumapaki. Mubishyira kure cyane ntibishobora kuyungurura neza urusaku rwinshi-rwinshi, gutakaza ingaruka zo gutesha agaciro. Imiterere ikosore iremeza ko imikorere yubushobozi buto mugushungura urusaku rwinshi bukoreshwa rwose.

C.kuza uburyo bwo kubangamira ubushobozi bwa decoupling

Kugirango ukomeze kunoza ubunyangamugayo bwamashanyarazi, ubushobozi bwinshi bwo gutesha agaciro akenshi bufitanye isano no kubangikanye. Intego nyamukuru yiyi myitozo ni ukugabanya induccess ihwanye (ESL) yubushobozi bwumuntu binyuze muburyo busa.

Iyo uhuye nubushobozi bwinshi bwo gutesha agaciro, kwitabwaho bigomba kwishyurwa no gushyira vias kubahawe ubushobozi. Imyitozo isanzwe nukubuza vias yimbaraga nubutaka. Intego nyamukuru yibi ni ukugabanya inducance hagati yo guta agaciro. Menya neza ko inductalicence nini cyane kurenza ESL yumukozi umwe, kugirango ubudafatabukire rusange nyuma yo kubona ubushobozi bwinshi bwo gutesha agaciro ni 1 / n. Mu kugabanya induccance, kuyuzuza imikorere birashobora kongera neza, kugenzura imbaraga zuzuye.

ImiterereKandi inzira yububasha, Indege Yimbere Indege Gutegura, kandi ikosore uburyo bwa Chip Imiterere no kwisiga ni ngombwa ningirakamaro muburyo bwa elegitoronike. Binyuze muburyo bukwiye no kurongora, turashobora kwemeza umutekano no gukora neza, kugabanya kwivanga urusaku, kandi tunoza imikorere rusange. Igishushanyo mbonera cy'imirongo no gutandukanya ubutegetsi kurushaho byerekana ibiranga indege zamashanyarazi, kugabanya kwivanga. Gukoresha neza imbaraga Chip Imiterere no kwinezeza no gutesha agaciro ubushobozi bwingirakamaro kubunyangamugayo, butuma itangwa rihamye kandi rikandagira urusaku rwibikoresho no gutuza.

Mubikorwa bifatika, ibintu bitandukanye nkubunini bwa none, bugari bwamanutse, umubare wa vias, ingaruka za cogene, nibindi, bakeneye kumvikana kugirango bafate imyanzuro idasanzwe no gufata ibyemezo byumvikana. Kurikiza ibisobanuro hamwe nibikorwa byiza kugirango umenye neza no guhitamo ubunyangamugayo. Gusa muri ubu buryo dushobora gutanga imbaraga zihamye kandi zikora neza kubikoresho bya elegitoroniki, byujuje ibikorwa byiyongera, no gutwara iterambere niterambere ryikoranabuhanga rya elegitoroniki.
