(1) Umurongo
Muri rusange, umurongo wumurongo wubugari ni 0.3mm (12mil), ubugari bwumurongo wamashanyarazi ni 0,77mm (30mil) cyangwa 1.27mm (50mil);intera iri hagati yumurongo numurongo na padi irarenze cyangwa ingana na 0.33mm (13mil)).Mubikorwa bifatika, ongera intera mugihe ibintu byemewe;
Iyo ubwinshi bwinsinga buri hejuru, imirongo ibiri irashobora gutekerezwa (ariko ntibisabwa) gukoresha IC pin.Ubugari bwumurongo ni 0,254mm (10mil), kandi intera yumurongo ntabwo iri munsi ya 0.254mm (10mil).Mubihe bidasanzwe, mugihe igikoresho cyibikoresho ari cyinshi nubugari bukaba bugufi, ubugari bwumurongo numurongo bishobora kugabanuka neza.
(2) Pad (PAD)
Ibisabwa byibanze kuri padi (PAD) nu mwobo winzibacyuho (VIA) ni: diameter ya disiki iruta diameter yumwobo kuri 0,6mm;kurugero, rusange-intego ya pin résistoriste, capacator, hamwe na sisitemu ihuriweho, nibindi, koresha disiki / umwobo ingana na 1,6mm / 0.8 mm (63mil / 32mil), socket, pin na diode 1N4007, nibindi, fata 1.8mm / 1.0mm (71mil / 39mil).Mubikorwa nyabyo, bigomba kugenwa ukurikije ingano yibigize.Niba ibintu byemewe, ingano ya padi irashobora kwiyongera muburyo bukwiye;
Ibikoresho byo gushiraho aperture byateguwe kuri PCB bigomba kuba bifite 0.2 ～ 0.4mm (8-16mil) binini kuruta ubunini nyabwo bwa pin.
(3) Binyuze kuri (VIA)
Mubisanzwe 1.27mm / 0.7mm (50mil / 28mil);
Iyo ubwinshi bwinsinga buri hejuru, binyuze mubunini burashobora kugabanuka muburyo bukwiye, ariko ntibigomba kuba bito cyane.Tekereza gukoresha 1.0mm / 0,6mm (40mil / 24mil).
