1: Isiseko sokukhetha ububanzi be-wire eprintiweyo: Ubuncinci bocingo oluprintiweyo lunxulumene nokuhamba kwentambo nge-wire: i-wire yocingo eliprintiweyo incinci, kwaye ichaphazela ukusebenza kwesekethe. Ububanzi belayini bubanzi kakhulu, ukuxinana kwentambo akuphezulu, indawo yeBhodi iyanda, ukongeza kwiindleko, ayihambelani ekumbiseni. Ukuba umthwalo wangoku ubalwa njenge-20a / mm2, xa ubukhulu be-copper clad yi-0.5 mm, (malunga nobubanzi be-1) buyi-1-2.54 mm (40-100 Mil) inokuhlangabezana neemfuno zesicelo semiluko jikelele. Ucingo olumhlaba kunye nokubonelela ngamandla kwiBhodi yezixhobo eziPhezulu kuNyulo ngokufanelekileyo kunokuba kukhululwa ngokufanelekileyo ngokwesayizi yamandla. Kwisekethe yedijithali ephantsi, ukwenzela ukuphucula ukuxinana kwe-wiring, ubuncinci bomgangatho wobuncinci bungoneliseki ngokuthatha i-0.254-1.2-1.2mm (10-15mil). Kwibhodi yesekethe enye, intambo yamandla. Ucingo olumhlaba luphuka kunecingo lomqondiso.

I-2: Ukuhamba ngomgca: Xa kuyi-1.5mm (malunga ne-60 mil), ukumelana nokuncitshiswa kwe-20 v. Mm (40-60 mi). Kwisekethe ephantsi voltage, ezinje ngeenkqubo zesekethi zedijithali, akunyanzelekanga ukuba baqwalasele i-voltage yobuqhetseba, njengoko inkqubo yemveliso ivumela, inokuba incinci kakhulu.

I-3: Pad: Kwi-1 / 8W isithintelo 1 / 8W, i-pad diameter ye-28MIL ikwanele, kwaye i-1/2 W, umngxunya okhokelayo uncitshisiwe, umkhuhlane wobhedu uncitshisiwe, umphumo wokwehla kwepad. Kulula ukuwa, umngxunya okhokelayo mncinci kakhulu, kwaye indawo yokubekwa kwecandelo kunzima.

4: Zoba umda wesekethe: Umgama omfutshane phakathi komda wendawo kunye nepayini yePIN ayinakuba ngaphantsi kwe-2mm, (5mm inesengqiqweni ngakumbi) ngenye indlela, kunzima ukusika loo nto.

5: Umgaqo weNdawo yeCandelo: A: UMGAQO-NKQUBO: UMNYANGO WOKWENZA: Kunye nesekethe eziphezulu, kufuneka zibekwe ngokwahlukeneyo ukunciphisa ukonwaba phakathi kweenkqubo. Kuhlobo olunye lwesekethe, amacandelo abekwe kwiibhloko kunye nezihluzo ngokwendlela yokuhamba kwesibonakaliso kunye nomsebenzi.

I-6: ICandelo lokuKhupha isiginali, into yokukhuphela isiginali kufuneka isondele kwiBhodi yeBhodi, yenza igalelo kunye nomgca wokufaka kunye nokuphuma kwegalelo legalelo kunye nemveliso.

I-7: Iindawo zokubekwa kwindawo: Iindawo zinokucwangciswa kuphela kwiindlela ezimbini, ethe tyaba kwaye nkqo kwaye nkqo. Ngaphandle koko, iplagi-cela avunyelwe.

I-8: isithuba senqaku. Kwiibhodi ezixineneyo eziphakathi, isithuba phakathi kwamacandelo amancinci anjengeendawo zokugcina amandla asezantsi, amachaphaza, ii-Deds, kunye nezinye izinto eziguqulayo zinxulumene nenkqubo yeplagi ye-plug kunye ne-welding. Ngexesha lokumangalela umbane, indawo yendawo yokuhamba inokuba yi-50-100mil (1.27-2.54mm). Kukhulu, njengokuthatha i-100mil, i-chip edibeneyo yesekethe, indawo yesekethe i-100,50mil.

9: Xa umahluko onokubakho phakathi kwezinto ezinkulu, isithuba phakathi kwamacandelo kufuneka sibe sikhulu ngokwaneleyo ukukhusela ukukhutshwa.

I-10: Kwi-IC, iCapaciling yeCawa kufuneka isondele kwikhonkco le-chip. Ngaphandle koko, impembelelo yokucocwa kuya kuba mbi ngakumbi. Kwisekethe idijithali, ukuze kuqinisekiswe ukusebenza ngokuthembekileyo kweenkqubo zephedi yedijithali, i-IC ye-IC Decoupling ifakwe phakathi kokunikezelwa kwamandla kunye nomhlaba wesekethe nganye esekwe kwisekethe. Ukucofa i-ACoupeling jikelele Sebenzisa i-ceramic candlators ngamandla e-0.01 ~ i-UF. Ukukhethwa komthamo wokuhombisa kweCanoupiling ngokubanzi kusekwe kwi-retiprocal yenkqubo yokusebenza rhoqo kwi-frequency F. Ukongeza, i-100 ye-10if ye-I-I-UF kunye ne-DEARACIC ye-UP nayo iyafuneka phakathi komsebenzi wesekethe.

I-11: Iqela lesekethe ngesandla lifanele lisondele kangangoko kwiPini ye-Clock ye-chip chip ye-chip engatshatanga yokunciphisa ubude besekethe yewotshi. Kwaye kungcono ukungaqhubi icingo elingezantsi.
