Ihiganwa rya PCB

Umusaruro wa PCB urwego rwo hejuru rwumuzunguruko ntusaba gusa ishoramari ryinshi mu ikoranabuhanga n’ibikoresho, ahubwo bisaba no gukusanya uburambe bwabatekinisiye n'abakozi bakora. Biragoye gutunganya kuruta ibibaho byumuzunguruko gakondo, kandi ubuziranenge bwabyo nibisabwa ni byinshi.

1. Guhitamo ibikoresho

Hamwe niterambere ryibikoresho byinshi bya elegitoroniki bikora cyane, hamwe nogukwirakwiza ibimenyetso byihuta kandi byihuta, ibikoresho byumuzunguruko bisabwa kugira igabanuka rya dielectric rihoraho hamwe na dielectric, kimwe na CTE nkeya hamwe no kwinjiza amazi make . igipimo hamwe nibikoresho byiza cyane bya CCL kugirango byuzuze ibisabwa kandi byizewe byubuyobozi bwo hejuru.

2. Igishushanyo mbonera cyimiterere

Ibintu byingenzi byasuzumwe mugushushanya imiterere ya laminated ni ukurwanya ubushyuhe, kwihanganira voltage, ingano yuzuye ya kole hamwe nubunini bwurwego rwa dielectric, nibindi. Amahame akurikira agomba gukurikizwa:

.

.

.

. Kuri plaque ya impedance, kwihanganira umubyimba wa dielectric bigenzurwa no kwihanganira icyiciro cya IPC-4101 C / M.

3. Kugenzura guhuza interineti

Ukuri kwindishyi zingana zimbere yimbere yimbere hamwe no kugenzura ingano yumusaruro bigomba kwishyurwa neza kubunini bwa graphique ya buri cyiciro cyibibaho birebire binyuze mumibare yakusanyirijwe mugihe cyibikorwa byuburambe hamwe namateka yamateka kuri runaka igihe cyigihe cyo kwemeza kwaguka no kugabanuka kwibibaho byibanze bya buri cyiciro. guhuzagurika.

4. Ikoranabuhanga ryimbere ryimbere

Kugirango habeho umusaruro wibibaho birebire, hashobora gutangizwa imashini yerekana amashusho (LDI) kugirango itezimbere ubushobozi bwo gusesengura ibishushanyo. Kugirango tunoze ubushobozi bwo gutondekanya umurongo, birakenewe gutanga indishyi ikwiye kubugari bwumurongo na padi mugushushanya, hanyuma ukemeza niba indishyi zishushanyije zubugari bwimbere bwimbere, umurongo utandukanijwe, ingano yimpeta, umurongo wigenga, nu mwobo-ku-murongo intera irumvikana, ubundi uhindure igishushanyo mbonera.

5. Gukanda

Kugeza ubu, uburyo bwo guhuza imyanya mbere yo kumurika burimo ahanini: imyanya ine ihagaze (Pin LAM), gushonga gushyushye, rivet, gushonga bishyushye hamwe na rivet. Ibicuruzwa bitandukanye byubaka uburyo butandukanye.

6. Uburyo bwo gucukura

Bitewe nubusumbane bwa buri cyiciro, isahani hamwe nu muringa bifite umubyimba mwinshi cyane, bizambara cyane bito bito kandi byoroshye kumena icyuma. Umubare wibyobo, umuvuduko wihuta nihuta bigomba guhinduka muburyo bukwiye.
