Njengomntu oqalayo kuyilo lwebhodi yePCB, loluphi ulwazi lwentshayelelo ofanele ulufunde?

Njengomntu oqalayo kuyilo lwebhodi yePCB, loluphi ulwazi lwentshayelelo ofanele ulufunde?Impendulo:

1. Isalathiso socingo: Isalathiso soyilo lwamacandelo kufuneka singqinelane kangangoko kunokwenzeka nomzobo weskim.Ulwalathiso lwe-wiring lukhethwa ukuba luhambelane naleyo yomzobo wesekethe.Ngokuqhelekileyo kuyimfuneko ukwenza iiparitha ezahlukeneyo kwi-welding surface ngexesha lenkqubo yokuvelisa.

2. Ukulungelelaniswa kwamacandelo kufuneka kube nengqiqo kunye nokufana, kwaye uzame ukucoceka kunye nokuhle.

3. Ukubekwa kwe-resistors kunye ne-diodes: i-plane kunye ne-vertical: (1) Ukukhululwa kwe-Flat: Xa inani lamacandelo esekethe lincinci kwaye ubungakanani bebhodi yesekethe bukhulu, ngokuqhelekileyo i-flat.(2) Ngokuthe nkqo: Xa inani lamacandelo esekethe likhulu kwaye ubungakanani bebhodi yesekethe buncinci, ihlala ime nkqo, kwaye isithuba phakathi kweepadi ezimbini ngokuqhelekileyo yi-intshi eyi-1 ukuya kwe-210.

4. Beka i-potentiometer,
Umgaqo wesihlalo se-IC: (1) I-Potentiometer: Xa uyila i-potentiometer, i-current kufuneka inyuswe xa i-potentiometer ilungiswa nge-clockwise.I-potentiometer kufuneka ifakwe kwisakhiwo somatshini wonke kunye neemfuno zokubeka ipaneli, kangangoko kunokwenzeka kumda webhodi, kwaye isibambo kufuneka siguqulwe ngaphandle.(2) Isihlalo se-IC: Kwimeko yokusebenzisa isihlalo se-IC, kuyimfuneko ukunikela ingqwalasela ekhethekileyo ukuba ngaba isalathiso se-groove yokumisa kwisihlalo se-IC sichanekile, nokuba ngaba izikhonkwane ze-IC zichanekile.

5. Ulungiselelo lweetheminali ezingenayo neziphumayo: (1) Iitheminali ezimbini ezifanelekileyo zingabi nkulu kakhulu, ngokubanzi malunga nee-intshi ezi-2 ukuya kuma-310.(2) Ukungena kunye nokuphuma kufuneka kugxininiswe kwi-1 ukuya kumacala e-2 kangangoko kunokwenzeka, kwaye akufanele kube nzima kakhulu.

6. Xa uqulunqa umzobo we-wiring, qaphela umyalelo wezikhonkwane kunye nokuhlukana kwamacandelo kufuneka kube nengqiqo.

7. Ngaphantsi kwesiseko sokuqinisekisa iimfuno zokusebenza kwesekethe, ukuyila kufuneka kube nengqiqo, i-wiring yangaphandle kufuneka isetyenziswe ngaphantsi, kwaye iingcingo kufuneka zihanjiswe ngokweemfuno.

8. Xa uyila umzobo wocingo, nciphisa i-wiring kwaye uzame ukwenza imigca ibe yincinci kwaye icace.

9. Ububanzi bomgca wetheminali kunye nesithuba semigca kufuneka sibe siphakathi.Izithuba phakathi kweepadi ezimbini ze-capacitor kufuneka zisondele kangangoko kunokwenzeka kwisithuba se-capacitor lead.

10. Uyilo kufuneka luqhutywe ngendlela ethile, umzekelo, ukusuka kwesobunxele ukuya kwesokudla, ukusuka phezulu ukuya phezulu.
