1. Uyilo ngokweemodyuli zesekethe, kunye neesekethe ezinxulumeneyo eziqaphela umsebenzi ofanayo zibizwa ngokuba yimodyuli. Amacandelo kwimodyuli yesiphaluka kufuneka athathe umgaqo wokugxininiswa okusondeleyo, kwaye isiphaluka sedijithali kunye nesekethe ye-analog kufuneka ihlulwe;
2. Akukho zixhobo okanye izixhobo ziya kuxhonywa ngaphakathi kwe-1.27mm yemingxuma enganyukiyo njengemingxuma yokubeka, imingxuma eqhelekileyo, kunye ne-3.5mm (ye-M2.5) kunye ne-4mm (ye-M3) ye-3.5mm (ye-M2.5) kunye I-4mm (ye-M3) ayiyi kuvunyelwa ukuba ifake amacandelo;
3. Kuphephe ukubeka i-vias phantsi kwee-resistors ezixhonywe ngokuthe tye, i-inductors (i-plug-ins), i-electrolytic capacitors kunye namanye amacandelo ukuphepha ukujikeleza okufutshane kwi-vias kunye necandelo lezindlu emva kokuthengiswa kwamaza;
4. Umgama phakathi komphandle wecandelo kunye nomda webhodi ngu-5mm;
5. Umgama phakathi komphandle wephedi yecandelo lokuxhoma kunye nomphandle wecandelo elimeleneyo elidibanisayo mkhulu kune-2mm;
6. Izixhobo zegobolondo zensimbi kunye neentsimbi (iibhokisi zokukhusela, njl.) azikwazi ukuchukumisa ezinye izinto, azikwazi ukusondela kwimigca eprintiweyo, iipads, kunye nesithuba sabo kufuneka sibe ngaphezu kwe-2mm. Ubungakanani bemingxuma yokumisa, imingxuma yokufaka i-fastener, imingxuma ye-oval kunye nezinye izikwere zesikwere ebhodini ukusuka kumda webhodi mkhulu kune-3mm;
7. Isixhobo sokufudumeza akufanele sibe kufuphi nocingo kunye ne-heat-sensitive element; isixhobo sokufudumeza okuphezulu kufuneka sisasazwe ngokulinganayo;
8. Isiseko sombane kufuneka silungiselelwe malunga nebhodi eprintiweyo ngokusemandleni, kwaye i-socket yamandla kunye ne-terminal yebhasi yebhasi edibeneyo kufuneka ilungiswe kwicala elinye. Ukunyamekela ngokukodwa kufuneka kuthatyathwe ukuba ungacwangciswanga iziseko zamandla kunye nezinye izihlanganisi ze-welding phakathi kweziqhagamshelo ukuququzelela i-welding yezi zixhobo kunye neziqhagamshelo, kunye noyilo kunye nokubopha kweentambo zombane. Ukucwangciswa kwezithuba zesokethi zamandla kunye nezixhumi ze-welding kufuneka ziqwalaselwe ukuququzelela ukufakwa kunye nokukhupha iiplagi zamandla;
9. Ukulungelelaniswa kwamanye amacandelo: Onke amacandelo e-IC ahambelana kwicala elinye, kwaye i-polarity yamacandelo e-polar imakishwe ngokucacileyo. I-polarity yebhodi eprintiweyo efanayo ayinakuphawulwa ngaphezu kwamacala amabini. Xa izikhombisi-ndlela ezimbini zivela, la macala mabini axhomekeke komnye nomnye;
10. I-wiring kumphezulu webhodi kufuneka ibe yincinci kwaye ibe nzima. Xa umehluko woxinaniso ukhulu kakhulu, kufuneka uzaliswe nge-foil yobhedu ye-mesh, kwaye igridi kufuneka ibe mkhulu kune-8mil (okanye 0.2mm);
11. Akufuneki kubekho imingxunya kwi-SMD pads ukuphepha ilahleko ye-solder paste kunye ne-solder yobuxoki yamacandelo. Imigca yesignali ebalulekileyo ayivumelekanga ukuba idlule phakathi kwezikhonkwane zesokhethi;
12. Isiqwenga silungelelaniswa kwicala elinye, isalathiso somlingiswa siyafana, kwaye isikhokelo sokupakisha siyafana;
13. Kangangoko kunokwenzeka, izixhobo ze-polarized kufuneka zihambelane ne-polarity marking direction kwibhodi enye.
