1. PCB bolodi mawonekedwe ayenera kukhala oyandikira kwambiri momwe angathere, 2 & TImes ikulimbikitsidwa; 2, 3, & TImes; 3, … Makongoletsedwe; Koma musapange gulu la Yin ndi Yang

2.PCB bolodi m’lifupi ≤260mm (SIEMENS mzere) kapena ≤300mm (FUJI mzere); Ngati kupereka kokhako kukufunika, kukula kwa bolodi ya PCB & TImes; Kutalika kwa 125 mm kapena kuchepera & TImes; 180mm.

3. The chimango akunja (clamping m’mphepete) wa bolodi PCB ayenera kutengera chatsekedwa-kuzungulira kamangidwe kuonetsetsa kuti bolodi PCB sadzakhala opunduka pambuyo chili pa fixture

4. Mtunda wapakati pakati pa mbale zing’onozing’ono uyenera kuyang’aniridwa pakati pa 75mm ndi 145mm

5. Pasapezeke chida chachikulu kapena chowonjezera pafupi ndi malo olumikizirana pakati pa chimango chakunja ndi mbale yaying’ono yamkati, komanso pakati pa mbale yaying’ono ndi mbale yaying’ono, m’mphepete mwa zigawozo ndi bolodi la PCB ziyenera kutsalira danga lalikulu kuposa 0.5mm kuti muwonetsetse kuti ntchito yodulira ikugwira bwino ntchito

6. Mabowo anayi otseguka amatsegulidwa pamakona anayi a chimango chakunja cha bolodi, ndi kabowo ka 4mm ± 0.01mm; Mphamvu ya dzenje liyenera kukhala lochepetsetsa kuti lisagwedezeke pokonza mbale zakumtunda ndi zapansi; Kabowo ndi kulondola kwa malo ziyenera kukhala zazitali, khoma labowo losalala popanda burr

7. Bwalo lililonse laling’ono la PCB liyenera kukhala ndi mabowo osachepera atatu, kabowo ka 3≤ mm6mm, mabowo oyimilira m’mphepete mwa 1mm saloledwa kutchinga

8. Chizindikiro chofotokozera PCB poyika bolodi lonse komanso poyika zida zabwino kwambiri chiyenera kukhazikitsidwa molumikizana ndi QFP ndi phula lochepera 0.65mm; Kuyika ma datum azizindikiro zama board ang’onoang’ono a PCB kuyenera kugwiritsidwa ntchito awiriawiri ndikukonzedwa pamagulu azoyikika.

9. Zigawo zazikulu ziyenera kukhala ndi malo okhala kapena mabowo oyikapo, monga mawonekedwe a I / O, maikolofoni, mawonekedwe a batri, switch yaying’ono, mawonekedwe am’mutu, mota, ndi zina zambiri.

10. Mukakhazikitsa mfundo ya nangula, malo otseguka otseguka opitilira 1.5mm nthawi zambiri amakhala pambali mozungulira nangula
