1. Isakhelo sangaphandle (icala elibambekayo) lejigsaw yePCB kufuneka yamkele uyilo oluvaliweyo lwelophu ukuqinisekisa ukuba ijigsaw yePCB ayisayi konakala emva kokulungiswa kwifixture;

2. PCB panel ububanzi ≤260mm (SIEMENS umgca) okanye ≤300mm (FUJI line); ukuba ukukhutshwa okuzenzekelayo kuyadingeka, ububanzi bepaneli yePCB × ubude ≤125 mm×180 mm;

3. Imilo yejigsaw yePCB kufuneka isondele kangangoko kwisikwere. Kucetyiswa ukuba usebenzise i-2×2, 3×3…

4. Umgama ophakathi phakathi kwamacwecwe amancinci ulawulwa phakathi kwe-75 mm kunye ne-145 mm;

5. Xa ubeka i-reference positioning point, ngokuqhelekileyo ushiye indawo engenakuchasana ne-1.5 mm enkulu kunayo ejikeleze indawo yokumisa;

6. Akufuneki kubekho izixhobo ezinkulu okanye izixhobo eziphumayo kufuphi nendawo yokudibanisa phakathi kwesakhelo sangaphandle sejigsaw kunye nebhodi encinci yangaphakathi, kunye nebhodi encinci kunye nebhodi encinci, kwaye kufuneka kubekho ngaphezu kwe-0.5mm phakathi kwamacandelo kunye umda wePCB Ukuqinisekisa ukusebenza okuqhelekileyo kwesixhobo sokusika;

7. Imingxuma emine yokumisa yenziwa kwiikona ezine zesakhelo sejigsaw, kunye nobubanzi be-4mm± 0.01mm; amandla emingxuma kufuneka abe yimodareyitha ukuqinisekisa ukuba abayi kuphuka ngexesha leebhodi eziphezulu kunye nezantsi; ukuchaneka kobubanzi bomngxuma kunye nesikhundla kufuneka sibe phezulu, kwaye udonga lomngxuma kufuneka lube mpuluswa kwaye lungabi nazibhubhu;

8. Ibhodi nganye encinci kwipaneli ye-PCB kufuneka ibe nemingxuma emithathu yokubeka ubuncinane, i-3≤aperture≤6 mm, kwaye akukho cingo okanye ukupakisha kuvunyelwe ngaphakathi kwe-1mm ye-edge positioning hole;

9. Iisimboli zereferensi ezisetyenziselwa ukubeka i-PCB iphela kunye nokubeka izixhobo ezinobumba obucolekileyo. Ngokomgaqo, i-QFP enesithuba esingaphantsi kwe-0.65mm kufuneka ibekwe kwindawo yayo ye-diagonal; iisimboli zokuma zesalathiso ezisetyenziselwa ukubekwa kwePCB intombi yebhodi kufuneka idityaniswe Isetyenzisiwe, icwangciswe kwikona echaseneyo yento yokubeka;

10. Amacandelo amakhulu kufuneka abe nezithuba zokumisa okanye imingxuma yokubeka, njenge-interface ye-I / O, i-microphone, i-battery interface, i-micro switch, i-earphone interface, i-motor, njl.
