1. The chimango akunja (clamping mbali) wa Bungwe la Circuit Board losindikizidwa gulu ayenera kutengera chatsekeka-lupu kapangidwe kuonetsetsa kuti PCB jigsaw sadzakhala wopunduka pambuyo anakonza pa fixture;
2. PCB gulu m'lifupi ≤260mm (SIEMENS mzere) kapena ≤300mm (FUJI mzere);ngati kugawira basi kumafunika, PCB gulu m'lifupi×utali ≤125 mm×180 mm; 3. Mawonekedwe a PCB jigsaw ayenera kukhala pafupi ndi lalikulu momwe angathere, ndi 2 × 2, 3 × 3, …… jigsaw akulimbikitsidwa;koma osayika pamodzi bolodi la yin ndi yang; 4. Mtunda wapakati pakati pa mbale zazing'ono umayendetsedwa pakati pa 75 mm ndi 145 mm; 5. Mukayika malo owonetserako, nthawi zambiri siyani malo osakanizidwa ndi 1.5 mm aakulu kuposa omwe azungulira poyikirapo; 
6. Sipayenera kukhala zida zazikulu kapena zida zowonekera pafupi ndi malo olumikizirana pakati pa chimango chakunja cha jigsaw chimango ndi bolodi yaying'ono yamkati, komanso pakati pa bolodi yaying'ono ndi bolodi yaying'ono, ndipo payenera kukhala danga lalikulu kuposa 0.5mm pakati. zigawo ndi m'mphepete mwa bolodi PCB.Kuonetsetsa ntchito yachibadwa ya chida kudula; 7. Mabowo anayi oyika amapangidwa kumakona anayi a chimango chakunja cha gulu la jigsaw, ndi mainchesi a 4mm ± 0.01mm;mphamvu ya mabowo iyenera kukhala yochepetsetsa kuti iwonetsetse kuti sungaphwanyidwe pa matabwa apamwamba ndi apansi;kulondola kwa dzenje ndi malo ayenera kukhala okwera, ndipo khoma la dzenje liyenera kukhala losalala komanso lopanda ma burrs.; 8. Gulu lirilonse laling'ono la PCB jigsaw liyenera kukhala ndi mabowo osachepera atatu, 3≤aperture≤6 mm, ndipo palibe mawaya kapena patching amaloledwa mkati mwa 1mm ya dzenje loyikira m'mphepete; 9. Zizindikiro zomwe zimagwiritsidwa ntchito poyika PCB yonse ndikuyika zida zomveka bwino.M'malo mwake, QFP yokhala ndi phula lochepera 0.65mm iyenera kukhazikitsidwa pamalo ake ozungulira;zizindikiro zogwiritsiridwa ntchito poyika bolodi la ana aakazi la PCB ziyenera kuphatikizidwa Zogwiritsidwa ntchito, zokonzedwa mbali ina ya chinthu choyikapo; 10. Zigawo zazikuluzikulu ziyenera kukhala ndi malo oyika kapena mabowo, monga mawonekedwe a I / O, maikolofoni, mawonekedwe a batri, micro switch, mawonekedwe a earphone, motor, etc.
