1. Isakhelo sangaphandle (icala lokubamba) le Ibhodi yeSekethe eprintiweyo indawo yolawulo kufuneka yamkele uyilo oluvaliweyo ukuqinisekisa ukuba ijigsaw yePCB ayisayi konakala emva kokuba ilungisiwe kumdlalo;
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 kakhulu kwisikwere kangangoko, kwaye 2×2, 3×3, …… ijigsaw iyacetyiswa;kodwa musa ukuhlanganisa ibhodi yeyin kunye neyang; 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 neendawo zokudibanisa phakathi kwesakhelo sangaphandle se-jigsaw frame kunye nebhodi encinci yangaphakathi, naphakathi kwebhodi encinci kunye nebhodi encinci, kwaye kufuneka kubekho indawo enkulu kune-0.5mm phakathi. amacandelo kunye nomphetho webhodi yePCB.Ukuqinisekisa ukusebenza okuqhelekileyo kwesixhobo sokusika; 7. Imingxuma emine yokumisa yenziwa kwiikona ezine zesakhelo sangaphandle sejigsaw panel, enobubanzi obuyi-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 kwi-PCB jigsaw kufuneka ibe nemingxuma emithathu yokubeka ubuncinane, i-3≤aperture≤6 mm, kwaye akukho cingo okanye ukupakisha kuvunyelwe ngaphakathi kwe-1mm yomgca wokumisa umda; 9. Iisimboli zereferensi ezisetyenziselwa ukubeka i-PCB iphela kunye nokubeka izixhobo ezinobumba obucolekileyo.Ngokomgaqo, i-QFP ene-pitch engaphantsi 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.
