Vias mu kibaho cyumuzunguruko bita vias, igabanijwemo ibyobo, umwobo uhumye hamwe nu mwobo washyinguwe ( Ubuyobozi bwumuzunguruko ).Zikoreshwa cyane cyane guhuza insinga mubice bitandukanye byurusobe rumwe kandi mubisanzwe ntabwo zikoreshwa nkibicuruzwa;

Amapaki mu kibaho cyumuzunguruko yitwa padi, agabanijwemo pin padi hamwe nubuso bwo hejuru;pin padi ifite ibyobo byagurishijwe, bikoreshwa cyane mugurisha ibice bya pin;mugihe hejuru yububiko bwo hejuru butagira umwobo ugurisha kandi bikoreshwa cyane mugurisha ibice bya Surface.

Binyuze cyane cyane uruhare rwumuriro wamashanyarazi, aperture yinyuze muri rusange ni nto, mubisanzwe mugihe cyose tekinoroji yo gutunganya ikibaho ishobora kubikora birahagije, kandi hejuru yinyuma irashobora gutwikirwa irangi rya mask yo kugurisha cyangwa ntayo;mugihe padi idakoreshwa mumashanyarazi gusa Uruhare rwo guhuza, ariko kandi ninshingano yo gutunganya imashini, aperture ya padi (birumvikana ko yerekeza kuri pin padi) igomba kuba nini bihagije kugirango inyure kuri pin yibigize, naho ubundi bizatera ibibazo byumusaruro;hiyongereyeho, ubuso bwa padi ntibugomba kugira wino ya Solder mask, kuko bizagira ingaruka kubigurisha, kandi muri rusange ubuso bwa padi bwometseho flux mugihe ukora ikibaho;na diameter ya aperture ya padi (mugihe yerekeza kuri pin padi) igomba guhura runaka Bitabaye ibyo, ntabwo bizagira ingaruka kumasudira gusa, ahubwo bizanatuma kwishyiriraho bidahinduka.
