1.

2. PCB Panel Warthth ≤260mm (siemens mzere) kapena ≤300mm (fuji pamzere); Ngati ndalama zokhazokha zimafunikira, PCB Panel Warthth × kutalika ≤125 mm × 180 mm;

3. Ndikulimbikitsidwa kugwiritsa ntchito 2 × 2, 3 × 3 ...

4. Mtunda pakati pa mbale zazing'onozo umayang'aniridwa pakati pa 75 mm ndi 145 mm;

5. Pokhazikitsa malo owerengera, nthawi zambiri siyani malo osakanikirana 1.5 mm zazikulu kuposa momwe zimakhalira.

6. Payenera kukhala zida zazikulu kapena zida zokutira pafupi ndi gawo lomwe lili pakati pa gawo lakunja la jigsaw ndi bolodi ing'onoing'ono, ndi bolodi yaying'ono, ndipo pamphepete mwa pcb kuti zitsimikizire kuti chida chodula;

7. Ndipo mabowo anayi okhazikitsa amapangidwa m'makona anayi a chimango cha jigsaw, ndi mainchesi a 4mm ± 0.01m; Mphamvu ya mabowo iyenera kukhala yochepetsera kuti isathe kuthyola mabodi apamwamba ndi otsika; Kutanthauzira kwa nyanja ndi udindo kuyenera kukhala lalitali, ndipo khoma la dzenje likhale losalala komanso lopanda mabatani;

8. Bolo laling'ono lililonse la PCB liyenera kukhala ndi mabowo atatu oyimilira, 3Baperteurep6 mm, ndipo palibe chotupa kapena chopopera chimaloledwa mkati mwa 1mm mtunda wokhazikika;

9. Zizindikiro zomwe zimagwiritsidwa ntchito poyimitsa PCB yonse ndikuyika madongosolo abwino. Mwakutero, QFP yokhala ndi nthawi yochepera 0,65mm iyenera kukhazikitsidwa pamalo ake opatsirana; Zizindikiro zomwe zikugwiritsidwa ntchito pofuna kugwiritsidwa ntchito kwa PCB mwana wamkazi wa PCB ayenera kuyikidwa pakona yogwiritsidwa ntchito pokona.
