Kuyilo lwePCB, uyilo lwamacandelo yenye yekhonkco elibalulekileyo. Kwiinjineli ezininzi ze-PCB, indlela yokubeka amacandelo ngokufanelekileyo nangempumelelo inemigangatho yayo. Sishwankathele izakhono zoyilo, malunga noku kulandelayo 10 Uyilo lwamacandelo e-elektroniki kufuneka lulandelwe!

Umzi-mveliso webhodi yesekethe

1. Landela umgaqo we-layout "enkulu kuqala, emva koko incinci, inzima kuqala, ilula kuqala", oko kukuthi, iisekethe zeyunithi ezibalulekileyo kunye namacandelo angundoqo kufuneka abekwe kuqala.

2. Umzobo webhloko yomgaqo kufuneka ubhekiswe kwi-layout, kwaye amacandelo aphambili kufuneka ahlelwe ngokuhambelana nokuhamba komqondiso oyintloko webhodi.

3. Ukulungelelaniswa kwamacandelo kufuneka kube lula ukulungiswa kunye nokugcinwa, oko kukuthi, iinqununu ezinkulu azikwazi ukubekwa kwiindawo ezincinci, kwaye kufuneka kubekho indawo eyaneleyo ejikeleze amacandelo afuna ukulungiswa.

4. Kwiindawo zesekethe zesakhiwo esifanayo, sebenzisa i-"symmetrical" ye-standard layout kangangoko kunokwenzeka.

5. Lungiselela ukwakheka ngokwemigangatho yokuhanjiswa okufanayo, iziko elilinganayo lomxhuzulane, kunye noyilo oluhle.

6. Uhlobo olufanayo lwamacandelo e-plug-in kufuneka lubekwe kwicala elinye kwicala le-X okanye le-Y. Uhlobo olufanayo lwamacandelo e-polarized discrete kufuneka kwakhona luzame ukuhambelana kwi-X okanye i-Y indlela yokuququzelela imveliso kunye nokuhlolwa.

7. Izinto zokufudumeza kufuneka zihanjiswe ngokubanzi ukuze ziququzelele ukutshatyalaliswa kobushushu be-veneer kunye nomatshini wonke. Izixhobo ezibuthathaka kwiqondo lobushushu ngaphandle kwesixhobo sokubona ubushushu kufuneka zigcinwe kude kumalungu avelisa ubushushu obukhulu.

8. Uyilo kufuneka luhlangabezane nezi mfuno zilandelayo kangangoko kunokwenzeka: uxhulumaniso lulonke lufutshane kangangoko kunokwenzeka, kwaye umgca wesignali obalulekileyo ngowona mfutshane; i-voltage ephezulu, umqondiso omkhulu wangoku kunye ne-low current, i-voltage ephantsi yombane ebuthathaka ibonakaliswe ngokupheleleyo; isignali ye-analog kunye nesiginali yedijithali yahluliwe; isignali yefrikhwensi ephezulu Yahlula kwiisignali ezisezantsi-frequency; isithuba samacandelo aphezulu-frequency kufuneka sanele.

9. I-layout of the decoupling capacitor kufuneka isondele ngokusemandleni kwi-pin yonikezelo lwamandla ye-IC, kwaye i-loop phakathi kwayo kunye nombane kunye nomhlaba kufuneka ibe yifutshane.

10. Kuyilo lwecandelo, ingqwalasela efanelekileyo kufuneka inikwe ekubekeni izixhobo ezisebenzisa umbane ofanayo kunye kangangoko kunokwenzeka ukuququzelela ukwahlulwa kombane kwixesha elizayo.
