1. Ukuhlelwa ngokwamamojula wesekethe, namasekhethi ahlobene aqaphela umsebenzi ofanayo abizwa ngokuthi imojuli. Izingxenye zemojula yesifunda kufanele zamukele isimiso sokugxila okuseduze, futhi isifunda sedijithali kanye nesifunda se-analog kufanele sihlukaniswe;
2. Azikho izingxenye noma amathuluzi azofakwa ngaphakathi kuka-1.27mm wezimbobo ezinganyuki njengezimbobo zokuma, izimbobo ezijwayelekile, no-3.5mm (ku-M2.5) no-4mm (ku-M3) okungu-3.5mm (ku-M2.5) kanye I-4mm (ye-M3) ngeke ivunyelwe ukukhweza izingxenye;
3. Gwema ukubeka ama-vias ngaphansi kwezinto eziphikisayo ezibekwe ngokuvundlile, ama-inductors (ama-plug-ins), ama-electrolytic capacitor nezinye izakhi ukuze ugweme ukujikeleza okufushane kwe-vias kanye nezindlu zengxenye ngemuva kokusoda kwegagasi;
4. Ibanga phakathi kwengaphandle lengxenye kanye nomphetho webhodi ngu-5mm;
5. Ibanga eliphakathi kwengaphandle lephedi yengxenye yokukhweza kanye nengaphandle lengxenye eseduze yokuhlanganisa likhulu kuno-2mm;
6. Izingxenye zegobolondo lensimbi nezingxenye zensimbi (amabhokisi okuvikela, njll.) azikwazi ukuthinta ezinye izingxenye, azikwazi ukusondela emigqeni ephrintiwe, amaphedi, futhi isikhala sazo kufanele sibe sikhulu kuno-2mm. Ubukhulu bezimbobo zokubeka, izimbobo zokufaka izinsimbi, izimbobo ezi-oval nezinye izimbobo zesikwele ebhodini kusukela onqenqemeni lwebhodi bukhulu kuno-3mm;
7. Isici sokushisa akufanele sibe seduze nocingo kanye nesici esizwela ukushisa; idivayisi yokushisa okuphezulu kufanele isatshalaliswe ngokulinganayo;
8. Isokhethi yamandla kufanele ihlelwe eduze kwebhodi eliphrintiwe ngangokunokwenzeka, futhi isokhethi yamandla kanye netheminali yebha yebhasi exhunywe kuyo kufanele ihlelwe ngakolunye uhlangothi. Ukunakekelwa okukhethekile kufanele kuthathwe ukuhlela amasokhethi amandla nezinye izixhumi zokushisela phakathi kwezixhumi ukuze kube lula ukushisela lezi zisekelo nezixhumi, kanye nokuklama nokubopha izintambo zamandla. Ukuhlelwa kwezikhala zamasokhethi amandla nezixhumi zokushisela kufanele kucatshangelwe ukuze kube lula ukuxhuma nokukhipha amapulaki amandla;
9. Ukuhlelwa kwezinye izingxenye: Zonke izingxenye ze-IC ziqondaniswe ohlangothini olulodwa, futhi i-polarity yezingxenye ze-polar imakwe ngokucacile. I-polarity yebhodi efanayo ephrintiwe ayikwazi ukumakwa ngaphezu kwezikhombisi-ndlela ezimbili. Lapho kuvela izikhombisi-ndlela ezimbili, lezi zikhombisi-ndlela ezimbili zincike komunye nomunye;
10. I-wiring ebusweni bebhodi kufanele ibe minyene futhi iminyene. Uma umehluko wokuminyana mkhulu kakhulu, kufanele ugcwaliswe nge-foil yethusi enemeshi, futhi igridi kufanele ibe nkulu kuno-8mil (noma u-0.2mm);
11. Akufanele kube khona izimbobo kuma-SMD pads ukugwema ukulahleka kokunamathisela kwe-solder kanye nokunamathisela okungamanga kwezingxenye. Imigqa yesignali ebalulekile ayivunyelwe ukuba idlule phakathi kwezikhonkwane zesokhethi;
12. Isiqephu siqondaniswe ohlangothini olulodwa, isiqondiso somlingisi siyafana, futhi isiqondiso sokupakisha siyafana;
13. Ngokusemandleni, amadivaysi e-polarized kufanele ahambisane nesiqondiso sokumaka i-polarity ebhodini elifanayo.
10. I-wiring ebusweni bebhodi kufanele ibe minyene futhi iminyene. Uma umehluko wokuminyana mkhulu kakhulu, kufanele ugcwaliswe nge-foil yethusi enemeshi, futhi igridi kufanele ibe nkulu kuno-8mil (noma u-0.2mm);
11. Akufanele kube khona izimbobo kuma-SMD pads ukugwema ukulahleka kokunamathisela kwe-solder kanye nokunamathisela okungamanga kwezingxenye. Imigqa yesignali ebalulekile ayivunyelwe ukuba idlule phakathi kwezikhonkwane zesokhethi;
12. Isiqephu siqondaniswe ohlangothini olulodwa, isiqondiso somlingisi siyafana, futhi isiqondiso sokupakisha siyafana;
13. Ngokusemandleni, amadivaysi e-polarized kufanele ahambisane nesiqondiso sokumaka i-polarity ebhodini elifanayo.
