Uburyo bwa PCB bwibibaho, bukoresha uburyo bwa chimique gakondo bwo kwangiza ahantu hadakingiwe.Ubwoko nko gucukura umwobo, uburyo bufatika ariko budakora neza.

Muburyo bwo guswera, igabanijwemo kandi inzira nziza ya firime hamwe na firime mbi.Inzira nziza ya firime ikoresha amabati ahamye kugirango irinde uruziga, kandi inzira mbi ya firime ikoresha firime yumye cyangwa firime itose kugirango irinde uruziga.Impande z'imirongo cyangwa amakariso zakozwe nabi hamwe na gakondokuriraburyo.Igihe cyose umurongo wiyongereyeho 0.0254mm, inkombe izaba ihindagurika kurwego runaka.Kugirango habeho umwanya uhagije, icyuho cyinsinga gipimwa buri gihe hafi ya buri cyuma cyashyizweho mbere.

Bifata igihe kinini cyo gutobora umuringa wumuringa kugirango habeho icyuho kinini mu cyuho cyinsinga.Ibi byitwa etch factor, kandi udafite uwabikoze atanga urutonde rusobanutse rwibyuho byibuze kuri buri une yumuringa, wige ibintu byakozwe nuwabikoze.Ni ngombwa cyane kubara ubushobozi buke kuri buri une yumuringa.Ikintu cya etch nacyo kigira ingaruka kumwobo wimpeta.Ingano ya gakondo yimpeta ni 0.0762mm yerekana amashusho + 0.0762mm gucukura + 0.0762 guteranya, hamwe 0.2286.Etch, cyangwa etch factor, nimwe mumagambo ane yingenzi agaragaza urwego rwibikorwa.

Mu rwego rwo kwirinda ko urwego rukingira rutagwa kandi rwujuje ibyangombwa bisabwa kugira ngo habeho imiti, imiti gakondo iteganya ko intera ntoya hagati y’insinga itagomba kuba munsi ya 0.127mm.Urebye ibintu byo kwangirika kwimbere no kugabanuka mugihe cyo guterana, ubugari bwinsinga bugomba kwiyongera.Agaciro kagenwa nubunini bwurwego rumwe.Umubyimba mwinshi wumuringa, niko bisaba gufata umuringa hagati yinsinga no munsi yikingira.Hejuru, hari amakuru abiri agomba gutekerezwa kubijyanye no guterwa imiti: ibintu bya etch - umubare wumuringa ushizwe kuri buri une;n'ikinyuranyo ntarengwa cyangwa ubugari bwikibanza kuri buri une y'umuringa.
