Awọn ọna idanwo melo lo wa fun awọn paati itanna eletiriki PCB?

Idanwo awọn paati itanna eletiriki PCB jẹ apakan pataki ti idanwo PCB. Nitorinaa, awọn ọna idanwo melo ni o wa fun awọn paati itanna eletiriki PCB?

1.Arinrin okun igbeyewo

Fun idanwo okun, afara oni nọmba le ṣee lo lati ṣe idanwo inductance lori ayelujara. Nitori awọn ṣiṣẹ igbohunsafẹfẹ ti awọnokun inductornigbagbogbo kii ṣe kekere, inductance le ṣe idanwo ni igbohunsafẹfẹ ju 10kHz.

2. Amunawa okun igbeyewo

Nipa idanwo awọn inductance D iye ti awọn transformer ká akọkọ okun, a le mọ boya awọntransformerni o ni ohun inter-Tan kukuru Circuit. Ọna kan pato jẹ: ṣeto afara oni-nọmba si 0.3V tabi isalẹ, 10kHz tabi loke, ati wiwọn iye D ti inductance coil akọkọ. Ti iye D ba tobi ju 0.1 lọ, o ṣe idajọ pe ẹrọ iyipada ti bajẹ ati pe ko le ṣee lo.

3. Iwari ti Hall awọn ẹrọ

Awọn sensọ alabagbepo wa ni ipese agbara ẹyọkan ati ipese agbara meji, bakanna bi iru iṣelọpọ lọwọlọwọ ati iru iṣelọpọ foliteji. Sensọ ipese agbara ẹyọkan ko ṣe awari lọwọlọwọ, ati ifihan agbara ni gbogbogbo 1/2 ti ipese agbara kan. Ti lọwọlọwọ ba jẹ 0, iṣafihan ifihan yoo yapa pupọ lati iye aarin. Sensọ tun le ṣe idanwo ni iwọn lati pinnu boya sensọ Hall ti bajẹ. Sensọ Hall pẹlu ipese agbara meji n jade 0 foliteji nigbati o ba ni imọ 0 lọwọlọwọ; nigbati o ba ni oye miiran ju 0 lọwọlọwọ, rere, odi ati titobi ti foliteji o wu n yipada pẹlu titobi ati itọsọna ti lọwọlọwọ ti o fa.

4. Igbeyewo ti relays

Awọn ašiše ti o wọpọ ti awọn relays pẹlu gige asopọ okun, awọn olubasọrọ ti ko paade, idaabobo olubasọrọ giga, ati awọn olubasọrọ ti o sun. Ọna ti o dara julọ lati ṣe idanwo boya iṣipopada naa jẹ deede ni lati fun iṣiṣẹ yii lekun, lo foliteji ti o ni iwọn si okun, ati lẹhinna ṣe idanwo itesiwaju olubasọrọ naa.

Fun ọja ibeere, jọwọ ṣayẹwo awọnọja iwe, ti o ba wa tun kaabo sipe wanipasẹ alaye olubasọrọ ni isalẹ, a yoo fesi si o laarin 24.
