Impamvu itaziguye yubushyuhe bwa PCB buterwa no kubaho kwagaciro k'umuzunguruko, ibikoresho bya elegitoronike bifite impamyabumenyi zitandukanye zo gutandukana kwamashanyarazi, kandi imbaraga zo gushyushya ziratandukanye.

2 Ibintu byubushyuhe bizamuka muri PCB:

(1) Ubushyuhe bwaho buzamuka cyangwa ubushyuhe bunini bwaho kuzamuka;

(2) Igihe gito cyangwa ubushyuhe burebure.

Mu isesengura ry'imbaraga za PCB, ibintu bikurikira muri rusange byasesenguwe:

1. Amashanyarazi

(1) Gusesengura ibiyobyabwenge kuri buri gice;

(2) Gusesengura ikwirakwizwa ryamashanyarazi kuri PCB.

2. Imiterere ya PCB

(1) ingano ya PCB;

(2) Ibikoresho.

3. Kwishyiriraho PCB

(1) Uburyo bwo kwishyiriraho (nko kwishyiriraho guhagarikwa no kwishyiriraho horizontal);

(2) Imiterere yo gukurura hamwe nintera mumazu.

4. Imirasire yubushyuhe

(1) guhuza imirasire yubuso bwa PCB;

(2) Itandukaniro ryubushyuhe hagati ya PCB hamwe nubuso bwegeranye nubushyuhe bwabo rwose;

5. Gukora ubushyuhe

(1) Shyira radiator;

(2) Gukora ibindi byukuri byo kwishyiriraho.

6. Convetion yubushyuhe

(1) convection karemano;

(2) Gukonja ku gahato.

Gusesengura PCB ibintu byavuzwe haruguru ni inzira nziza yo gukemura ubushyuhe bwa PCB, akenshi mubicuruzwa na sisitemu ifitanye isano no kubara ukurikije ibintu bifatika cyangwa ibintu byihariye byabazwe neza cyangwa ubushyuhe bwagereranijwe.
