Nigute ushobora guhitamo neza ibikoresho bya PCB nibikoresho bya elegitoroniki

Guhitamo ibikoresho bya PCB nibikoresho bya elegitoronike byize cyane, kuberako abakiriya bakeneye gutekereza kubintu byinshi, nkibipimo byerekana imikorere yibigize, imikorere, hamwe nubwiza nicyiciro cyibigize.

Uyu munsi, tuzatangiza uburyo bwo guhitamo neza ibikoresho bya PCB nibikoresho bya elegitoroniki.

Guhitamo ibikoresho bya PCB

Ihanagura rya FR4 epoxy fiberglass ikoreshwa mubikoresho bya elegitoronike, guhanagura polyimide fiberglass ikoreshwa mubushyuhe bwo hejuru bwibidukikije cyangwa imbaho ​​zumuzunguruko zoroshye, kandi polytetrafluoroethylene ya fiberglass yohanagura irakenewe kumuzunguruko mwinshi. Kubicuruzwa bya elegitoronike bifite ubushyuhe bwinshi bwo gukwirakwiza, ibyuma bigomba gukoreshwa.

Ibintu bigomba kwitabwaho muguhitamo ibikoresho bya PCB:

.

(2) Coefficient nkeya yo kwagura ubushyuhe (CTE) irakenewe. Bitewe na coefficient idahuye yo kwagura ubushyuhe mu cyerekezo cya X, Y n'ubugari, biroroshye gutera PCB ihindagurika, kandi bizatera kuvunika umwobo no kwangiza ibice mubihe bikomeye.

(3) Birakenewe kurwanya ubushyuhe bwinshi. Mubisanzwe, PCB isabwa kugira ubushyuhe bwa 250 ℃ / 50S.

(4) Birakenewe neza. Urupapuro rwintambara rwa PCB kuri SMT ni <0.0075mm / mm.

. Kurwanya insulasiyo, imbaraga za voltage, arc kurwanya guhuza ibisabwa nibicuruzwa.

Guhitamo ibikoresho bya elegitoroniki

Usibye kuzuza ibisabwa mumikorere y'amashanyarazi, guhitamo ibice bigomba no kuba byujuje ibisabwa byo guterana hejuru kubice. Ariko nanone ukurikije ibikoresho byumurongo wibikoresho hamwe nuburyo bwibicuruzwa kugirango uhitemo ifumbire mvaruganda, ingano y'ibigize, ifishi y'ibikoresho.

Kurugero, mugihe inteko yubucucike bukabije isaba guhitamo ibice bito bito: niba imashini ishiraho idafite ubunini bwagutse bwo kugaburira, ibikoresho bya SMD byo gupakira ntibishobora gutoranywa;
