Mu musaruro wumuzunguruko, ikiraro cyamavuta yicyatsi nacyo cyitwa ikiraro cya mask yagurishijwe n urugomero rwabigenewe.Ni "akato ko kwigunga" gakozwe nuruganda rwumuzunguruko kugirango hirindwe uruziga rugufi rwibinini bya SMD.Niba ushaka kugenzura ikibaho cyoroshye cya FPC (FPC flexible circuit board) ikiraro cyamavuta yicyatsi, ugomba kugenzura mugihe cya mask yo kugurisha.Hariho ubwoko bubiri bwibikoresho bya FPC byoroshye kugurisha ibikoresho bya mask: wino na firime.

Uruhare rwa FPC rworoshye rwumuzunguruko wububiko

1. Kwikingira hejuru;

2. Kurinda umurongo kugirango wirinde inkovu z'umurongo;

3. Irinde ibintu byamahanga byayobora kugwa mumuzunguruko no gutera inzira ngufi.

Irangi ikoreshwa kubagurisha irwanya ubusanzwe ifotora ibyiyumvo, bita wino ya fotosensique.Mubisanzwe hariho icyatsi, umukara, umweru, umutuku, umuhondo, ubururu, nibindi. Igipfukisho cya firime, muri rusange umuhondo, umukara n'umweru.Umukara ufite igicucu cyiza kandi cyera gifite ibitekerezo byinshi.Irashobora gusimbuza amavuta yera umukara kumurongo winyuma FPC yoroheje (FPC flexible circuit board).Ikibaho cyoroshye cya FPC (ikibaho cyumuzunguruko wa FPC) kirashobora gukoreshwa mumasoko yo kugurisha wino cyangwa gutwikira firime.
