Ibikoresho bya PCB byoherejwe, bikoresha inzira gakondo yimiti kuri Corrode ahantu hateganijwe. Ubwoko bwo gucukura umwobo, ibintu bifatika ariko bidakora.

Muburyo bwa ETCHING, bigabanijwemo kandi inzira nziza ya firime hamwe nuburyo bubi bwa firime. Inzira nziza ya firime ikoresha amabati yagenwe kugirango urinde umuzenguruko, kandi inzira mbi ya firime ikoresha firime yumye cyangwa firime itose kugirango urinde umuzenguruko. Impande zimirongo cyangwa padi ni gyshapen hamwe na gakondoETCHINGUburyo. Igihe cyose umurongo wiyongereyeho 0.0254mm, inkombe izakunda kurwego runaka. Kugirango umenye neza, icyuho cya Wire buri gihe gipimwa mugihe cya hafi cya buri mbere.

Bifata igihe kinini kuri etch ounce yumuringa kugirango ukore icyuho kinini mumusatsi winsinga. Ibi byitwa ingingo, kandi utabikoze gutanga urutonde rusobanutse rwibiryo bito kuri buri muringa, wige ikintu cyabigenewe. Ni ngombwa cyane kubara ubushobozi buke kuri ounce yumuringa. Ikintu cya ETCH kigira ingaruka kandi umwobo wuwabikoze. Ingano yimikorere gakondo ni 0. Etch, cyangwa etch ikintu, nimwe mumagambo ane yingenzi agaragaza urwego.

Kugirango wirinde igice cyo gukingira kugwa no guhura nigikorwa cya SPOCINE ibisabwa byimiti, entos gakondo iteganya ko insinga ntoya hagati yinsinga zitagomba kuba 0.127mm. Urebye ibintu byorose byimbere kandi munsi yimbere mugihe cya etching, ubugari bwinsire igomba kwiyongera. Agaciro kagenwa nubwinshi bwurwego rumwe. Ikibyimba umuringa, igihe kinini gifata kuri etch umuringa hagati yinsinga no munsi yumuriro. Hejuru, hari amakuru abiri agomba gufatwa nkibimenyetso byimiti: ikintu cya etch - umubare wumuringa watsindiye kuri ounce; Kandi icyuho gito cyangwa ubugari bwa pitch kuri ounce yumuringa.
