Njengomfundamakhwela ekwakhiweni kwebhodi le-PCB, yiluphi ulwazi lwesingeniso okufanele ulufunde kahle?Impendulo:

1. Ukuqondiswa kwezintambo: Isiqondiso sesakhiwo sezingxenye kufanele sihambisane ngangokunokwenzeka nomdwebo wohlelo.Isiqondiso sezintambo kungcono siqondane naleso somdwebo wesifunda.Ngokuvamile kuyadingeka ukwenza amapharamitha ahlukahlukene endaweni yokushisela ngesikhathi senqubo yokukhiqiza.

2. Ukuhlelwa kwezingxenye kufanele kube okunengqondo futhi okufanayo, futhi kulwele ukucoceka nokuhle.

3. Ukubekwa kwama-resistors nama-diode: indiza nokuma: (1) Ukukhululwa kwe-flat: Uma inani lezingxenye zesifunda lincane futhi ubukhulu bebhodi lesifunda likhulu, ngokuvamile liyisicaba.(2) Ime mpo: Uma inani lezingxenye zesekethe likhulu futhi usayizi webhodi lesekethe lincane, ngokuvamile liyama, futhi isikhala phakathi kwamaphedi amabili ngokuvamile singu-1 kuya ku-210 amayintshi.

4. Beka i-potentiometer,
Umgomo wesihlalo se-IC: (1) I-Potentiometer: Lapho uklama i-potentiometer, yamanje kufanele yandiswe lapho i-potentiometer ilungiswa ngokwewashi.I-potentiometer kufanele ibekwe esakhiweni somshini wonke kanye nezidingo zesakhiwo sephaneli, ngangokunokwenzeka emaphethelweni ebhodi, futhi isibambo kufanele siphendulelwe ngaphandle.(2) Isihlalo se-IC: Endabeni yokusebenzisa isihlalo se-IC, kuyadingeka ukunaka ngokukhethekile ukuthi isiqondiso se-groove yokumisa esihlalweni se-IC silungile, nokuthi izikhonkwane ze-IC zilungile yini.

5. Ukuhlelwa kwamatheminali angenayo naphumayo: (1) Amatheminali okuhola amabili afanelekile akufanele abe makhulu kakhulu, ngokuvamile angaba amayintshi angu-2 kuya kwangu-310.(2) Ukungena nokuphuma kufanele kugxilwe ku-1 kuya ku-2 izinhlangothi ngangokunokwenzeka, futhi akufanele kube okuhluke kakhulu.

6. Uma uklama umdwebo wezintambo, qaphela ukuhleleka kwezikhonkwane futhi ukuhlukaniswa kwezingxenye kufanele kube okunengqondo.

7. Ngaphansi kwesisekelo sokuqinisekisa izidingo zokusebenza kwesifunda, ukuklama kufanele kube okunengqondo, izintambo zangaphandle kufanele zisetshenziswe kancane, futhi izintambo kufanele zihanjiswe ngokuvumelana nezidingo.

8. Lapho uklama umdwebo wezintambo, nciphisa izintambo bese uzama ukwenza imigqa ibe mfushane futhi icace.

9. Ububanzi bomugqa wetheminali kanye nesikhala semigqa kufanele kube okulingene.Isikhala phakathi kwamaphedi amabili e-capacitor kufanele sisondele ngangokunokwenzeka esikhaleni se-capacitor lead.

10. Umklamo kufanele wenziwe ngokulandelana okuthile, isibonelo, ukusuka kwesobunxele kuya kwesokudla, ukusuka phezulu kuya phansi.
