(1) Mzere
Nthawi zambiri, m'lifupi mzere chizindikiro ndi 0.3mm (12mil), mphamvu mzere m'lifupi ndi 0.77mm (30mil) kapena 1.27mm (50mil); mtunda pakati pa mzere ndi mzere ndi pad ndi wamkulu kuposa kapena wofanana ndi 0.33mm (13mil) ). Pochita ntchito, onjezani mtunda ngati mikhalidwe ikuloleza;
Pamene kachulukidwe ka mawaya ali okwera, mizere iwiri imatha kuganiziridwa (koma osavomerezeka) kugwiritsa ntchito zikhomo za IC. M'lifupi mwake mzere ndi 0.254mm (10mil), ndipo mizere siing'ono kuposa 0.254mm (10mil). Pazochitika zapadera, pamene zikhomo za chipangizo zimakhala zowuma komanso m'lifupi mwake n'zopapatiza, m'lifupi mwa mzere ndi kusiyana kwa mzere kungachepetsedwe moyenera.
(2) Pad (PAD)
Zofunikira pa ma pads (PAD) ndi mabowo osinthira (VIA) ndi: m'mimba mwake wa diski ndi wamkulu kuposa m'mimba mwake wa dzenje ndi 0.6mm; mwachitsanzo, ma pini resistors, ma capacitor, ndi mabwalo ophatikizika, ndi zina zambiri, amagwiritsa ntchito disk/bowo kukula kwa 1.6mm/0.8 mm (63mil/32mil), sockets, pini ndi diode 1N4007, ndi zina zotero, kutengera 1.8mm/ 1.0mm (71mil/39mil). Muzogwiritsira ntchito zenizeni, ziyenera kutsimikiziridwa molingana ndi kukula kwa chigawo chenichenicho. Ngati mikhalidwe ikuloleza, kukula kwa pad kumatha kukulitsidwa moyenera;
Kabowo koyikirako kopangidwa pa PCB kuyenera kukhala kokulirapo kuposa 0.2 ~ 0.4mm (8-16mil) kuposa kukula kwenikweni kwa chigawocho.
(3) Kudzera (VIA)
Nthawi zambiri 1.27mm/0.7mm (50mil/28mil);
Mawaya akachulukirachulukira, kukula kwake kumatha kuchepetsedwa moyenera, koma sikuyenera kukhala kocheperako. Ganizirani kugwiritsa ntchito 1.0mm/0.6mm (40mil/24mil).

(4) Zofunikira pamapadi, mizere, ndi ma vias
PAD ndi VIA: ≥ 0.3mm (12mil)
PAD ndi PAD: ≥ 0.3mm (12mil)
PAD ndi TRACK: ≥ 0.3mm (12mil)
TRACK ndi TRACK: ≥ 0.3mm (12mil)
Pakachulukidwe kwambiri:
PAD ndi VIA: ≥ 0.254mm (10mil)
PAD ndi PAD: ≥ 0.254mm (10mil)
PAD ndi TRACK: ≥ 0.254mm (10mil)
TRACK ndi TRACK: ≥ 0.254mm (10mil)
