Umubyimba wumuringa nuburyo bwo gupfa kuri 4L PCB

Nigute ushobora guhitamo muburyo bukwiye bwumuringa wumuringa hamwe na fayili yumuringa bipfa guterwa kuri 4-PCB

Mugushushanya no gukora imbaho ​​zumuzingo zacapwe (PCBs), hari ibintu byinshi ugomba gusuzuma. Ikintu cyingenzi ni uguhitamo icyerekezo gikwiye cyumuringa hamwe numuringa wumuringa wo gupfa, cyane cyane mugihe ukorana na PCBs 4. Muri iyi nyandiko ya blog, tuzaganira kumpamvu aya mahitamo ari ngombwa kandi tuguhe inama zuburyo bwo gufata icyemezo cyiza.

Akamaro k'uburebure bw'umuringa mu kibaho

Ubunini bw'umuringa bwa PCB bugira uruhare runini mu mikorere rusange no kwizerwa. Ihindura mu buryo butaziguye ubushobozi bwubuyobozi bwo kuyobora neza amashanyarazi no gucunga ubushyuhe. Guhitamo umubyimba ukwiye wumuringa ningirakamaro kugirango PCB ishobore gukora amashanyarazi asabwa nta gushyuha gukabije cyangwa kugabanuka kwa voltage.

Iyo PCB igizwe n-ibice 4, ibintu birushaho kuba ingorabahizi. Ibice byinyongera muri PCB byongera igishushanyo mbonera, kandi uburebure bwumuringa busaba gutekereza neza kugirango ukomeze imikorere myiza. Ariko bigomba kwibukwa ko ubunini bugomba gutoranywa ukurikije ibisabwa byihariye bya PCB aho gukurikiza buhumyi inganda zose.

Ibintu ugomba gusuzuma mugihe uhitamo In-Board Umuringa

1. Ubushobozi bwo gutwara ubu:Kimwe mubitekerezo byingenzi muguhitamo uburebure bwumuringa nubushobozi bwo gutwara ibintu. Igishushanyo cyumuzingi hamwe nimbaraga zikomeye cyangwa porogaramu zisaba ibikorwa-bigezweho bigomba gukoresha ibimenyetso byumuringa mwinshi kugirango wirinde ubushyuhe bukabije.

2. Gucunga amashyuza:Gukwirakwiza ubushyuhe neza ningirakamaro mubuzima bwa PCB no kwizerwa. Umuringa mwinshi cyane ufasha kongera ubushyuhe mugutanga ubuso bunini bwo kohereza ubushyuhe. Kubwibyo, niba porogaramu yawe irimo ibice bitanga ubushyuhe bwinshi, birasabwa guhitamo umuringa mwinshi.

3. Kugenzura inzitizi:Kubisabwa bimwe, nkumurongo mwinshi cyangwa radiyo yumurongo wa radiyo, gukomeza impedance nyayo nibyingenzi. Muri iki kibazo, uburebure bwumuringa bwimbere bugomba gutoranywa neza kugirango ugumane agaciro kifuzwa. Umuringa muremure cyane ufasha kugera kugenzura neza.

Guhitamo iburyo bw'umuringa wo gupfa

Usibye umubyimba wumuringa, umuringa wumuringa upfa guta ikindi kintu cyingenzi ugomba gusuzuma. Igikorwa cyo gupfa kigena ubuziranenge nuburinganire bwumuringa kuri PCB. Hano hari ibintu bimwe na bimwe ugomba kuzirikana muguhitamo inzira yo gupfa neza:

1. Kurangiza ubuso:Igikorwa cyo gupfa kigomba kwemeza neza kandi neza. Ibi nibyingenzi cyane kugirango habeho kugurisha neza no guhuza amashanyarazi yizewe. Kurangiza neza birashobora gutera ibibazo nkabagurisha hamwe kunanirwa cyangwa ubushobozi budahagije.

2. Gufatanya:Igice cy'umuringa kigomba kuba gifatanye neza na substrate ya PCB kugirango wirinde gusenyuka cyangwa kugwa mugihe cyo gukora. Igikorwa cyo gupfa kigomba kwemeza neza guhuza umuringa nibikoresho bya substrate (ubusanzwe FR-4) kugirango PCB yizere kandi irambe.

3. Guhuzagurika:Guhuza umubyimba wumuringa muri PCB yose ni ngombwa kugirango habeho gukora amashanyarazi ahoraho no kugenzura inzitizi. Igikorwa cyo guta apfa kigomba gutanga ibisubizo bihamye no kugabanya itandukaniro mubyimbye byumuringa.

Shakisha impirimbanyi

Kugaragaza uburinganire bukwiye hagati yimikorere, kwizerwa nigiciro ni ngombwa muguhitamo icyerekezo gikwiye cyumuringa wumuringa hamwe na fayili yumuringa bipfa. Umuringa muremure cyane hamwe nuburyo bugezweho bwo gupfa-guta bishobora kunoza imikorere, ariko kandi byongera ibiciro byinganda. Birasabwa kugisha inama numushinga wuburambe wa PCB cyangwa umuhanga kugirango umenye neza umuringa mwiza wumuringa hamwe nuburyo bwo gupfa bizahuza neza nibisabwa byihariye hamwe nimbogamizi zingengo yimari.

mu gusoza

Guhitamo neza muburyo bwububiko bwumuringa hamwe numuringa wa foil bipfa guterwa ningirakamaro kugirango harebwe imikorere yigihe kirekire, kwizerwa no gukora bya PCB igizwe na 4. Gutekereza neza kubintu nkubushobozi bwo gutwara ibintu, gucunga ubushyuhe, no kugenzura inzitizi ningirakamaro muguhitamo neza. Byongeye kandi, guhitamo uburyo bwo gupfa butanga ubuso burangije neza, gufatana neza, hamwe nibisubizo bihamye bizarushaho kunoza ireme rusange rya PCB. Wibuke, igishushanyo cya PCB cyihariye kandi ugasanga uburinganire bwuzuye hagati yubuhanga bukenewe hamwe ninganda zishoboka nurufunguzo rwo gutsinda.
