Ekwakhiweni kwe-PCB, ukwakheka kwezingxenye kungenye yezixhumanisi ezibalulekile. Konjiniyela abaningi be-PCB, indlela yokubeka izingxenye ngokunengqondo nangempumelelo inesethi yayo yezindinganiso. Sifingqe amakhono okuhlela, cishe okulandelayo 10 Isakhiwo sezingxenye ze-elekthronikhi sidinga ukulandelwa!
Imboni yebhodi lesifunda
1. Landela isimiso sokuhlela esithi "okukhulu kuqala, bese kuba kuncane, kunzima kuqala, kulula kuqala", okungukuthi, amasekhethi amayunithi abalulekile kanye nezingxenye eziyinhloko kufanele zibekwe kuqala.
2. Umdwebo we-block block kufanele ubhekiswe kuwo ekuhleleni, futhi izingxenye eziyinhloko kufanele zihlelwe ngokuvumelana nokugeleza kwesignali eyinhloko yebhodi.
3. Ukuhlelwa kwezingxenye kufanele kube lula ukulungisa iphutha nokugcinwa, okungukuthi, izingxenye ezinkulu azikwazi ukubekwa eduze kwezingxenye ezincane, futhi kufanele kube nesikhala esanele ezizungeze izingxenye ezidinga ukulungiswa.
4. Ezingxenyeni zesifunda zesakhiwo esifanayo, sebenzisa ukwakheka okujwayelekile "okulinganayo" ngangokunokwenzeka.
5. Lungiselela ukwakheka ngokuvumelana nezindinganiso zokusabalalisa okufanayo, isikhungo esilinganiselayo samandla adonsela phansi, kanye nesakhiwo esihle.
6. Uhlobo olufanayo lwezingxenye ze-plug-in kufanele lubekwe ohlangothini olulodwa ku-X noma u-Y. Uhlobo olufanayo lwezingxenye ze-polarized discrete kufanele futhi lulwele ukungaguquguquki kusiqondisindlela esingu-X noma esingu-Y ukuze kube lula ukukhiqizwa nokuhlolwa.

7. Izinto zokushisa kufanele zivame ukusabalalisa ngokulinganayo ukuze kube lula ukuchithwa kokushisa kwe-veneer kanye nomshini wonke. Amadivayisi azwelayo kuzinga lokushisa ngaphandle kwesici sokuthola izinga lokushisa kufanele agcinwe kude nezingxenye ezikhiqiza ukushisa okukhulu.
8. Isakhiwo kufanele sihlangabezane nezidingo ezilandelayo ngangokunokwenzeka: ukuxhuma okuphelele kufushane ngangokunokwenzeka, futhi umugqa wesiginali oyinhloko mfushane kakhulu; I-voltage ephezulu, isignali yamanje enkulu kanye ne-low current, isignali ephansi ye-voltage ebuthakathaka ihlukaniswe ngokuphelele; isignali ye-analog nesignali yedijithali ihlukaniswe; isignali yefrikhwensi ephezulu Hlukanisa kumasignali amaza aphansi; Isikhala sezingxenye ze-high-frequency kufanele sanele.
9. Ukuhlelwa kwe-decoupling capacitor kufanele kube eduze ngangokunokwenzeka nephinikhodi yokunikeza amandla ye-IC, futhi iluphu phakathi kwayo nogesi kanye nomhlabathi kufanele kube kufushane kakhulu.
10. Ekuhlelweni kwengxenye, ukucatshangelwa okufanele kufanele kucatshangelwe ekubekeni izisetshenziswa zisebenzisa ugesi ofanayo ndawonye ngangokunokwenzeka ukuze kube lula ukuhlukaniswa kwamandla kagesi esikhathini esizayo.
