Kuyesedwa

Kufotokozera Kwachidule:


Mankhwala Mwatsatanetsatane

Bungwe loyang'anira dera likakhala logulitsidwa, kuwunika ngati bolodi la dera likhoza kugwira bwino ntchito, nthawi zambiri silipereka mwachindunji kwa oyang'anira dera, koma tsatirani njira

pansipa:

1. Kaya kulumikizana kuli kolondola.

2. Kaya mphamvu yamagetsi ndiyachidule.

3.Kukhazikitsa mawonekedwe azinthu.

4. Chitani zoyeserera zapa dera loyambira koyamba kuonetsetsa kuti sipadzakhalanso dera lalifupi pambuyo pake kuyatsa. Kuyesa kwamphamvu kumangoyambitsidwa pambuyo poyeserera kwa hardware pamwambapa pamaso pa mphamvu yatha.

Testing-for-PCBA

Ntchito zina pakakonza madongosolo azamagetsi

1. Dziwani mfundo yoyeserera

2. Khazikitsani kampu yolumikizira zolakwika

3. Sankhani chida choyezera

4. Kuthetsa zolakwika

5.Kusokoneza kwathunthu

Kuzindikira mphamvu

1. Kuwona mphamvu

2. Kusakhazikika kolakwika

3. Kusintha kwamphamvu

Pakukonza zolakwika, ndikofunikira kuyang'anitsitsa ndikusanthula zochitika zoyeserera ndikupanga zolemba kuti zitsimikizire kukhulupirika ndi kudalirika kwa zomwe zikuyesedwazi.

Zinthu zomwe zimafunikira chidwi pakakonza madongosolo

Kaya zotsatira zolakwika ndizolondola zimakhudzidwa makamaka ngati kuchuluka kwa mayeso kuli kolondola kapena ayi komanso kulondola kwa mayeso. Kuti muwonetsetse zotsatira zoyesa, cholakwika choyesachi chiyenera kuchepetsedwa ndikuyesedwa

Kuti muyese kulondola, muyenera kulabadira mfundo izi:

1. Gwiritsani ntchito poyikira pansi chida choyesera moyenera

2. Kuyika kolowera kwa chida chogwiritsira ntchito kuyeza mphamvu yamagetsi kuyenera kukhala kwakukulu kwambiri kuposa kupendekera kofanana kwa malo omwe adayeza

3. Mawindo a chida choyesera ayenera kukhala okulirapo kuposa kuchuluka kwa dera loyesedwa.

4. Sankhani malo oyesera molondola

5. Njira yoyezera iyenera kukhala yabwino komanso yotheka

6. Pakukonza zolakwika, sikuti muyenera kungoyang'anira ndikuyeza, komanso kukhala akatswiri kujambula

 

Zovuta pakusokoneza

Yang'anani chifukwa chake vutolo mosamala, ndipo musachotse mzerewo ndikubwezeretsanso pomwe cholakwacho sichingathetsedwe. Chifukwa ngati ili ndi vuto, silingathetsedwe ngakhale mutayikanso

 

Vuto.

1. Njira yowunika yolakwika

2. Chochitika cholephera komanso chifukwa cholephera

1) Chodabwitsa chodziwika cholephera: dera lokulitsa lilibe chizindikiro cholowetsera koma mawonekedwe amawu

2) Choyambitsa cholephera: chinthu chomalizidwa chimalephera patatha nthawi yogwiritsidwa ntchito, chomwe chingakhale chifukwa cha kuwonongeka kwa zinthu, dera lalifupi kapena dera lotseguka polumikizana, kapena kusintha kwa zinthu, ndi zina zambiri.

3. General njira onani kulephera

1) Njira yowonera mwachindunji: Fufuzani ngati kusankha ndi kugwiritsa ntchito chida ndicholondola, ngati mphamvu yamagetsi yamagetsi ndi polarity zikukwaniritsa zofunikira; kaya zikhomo za polarity zalumikizidwa molondola,

Kaya kulumikizana kolakwika, kusowa kolumikizana kapena kugundana. Kaya zingwezo ndi zomveka; ngakhale bolodi losindikizidwa ndilofupikitsa, ngati ma resistor ndi ma capacitors awotchedwa kapena kuphulika. Zowonera pazowonera zili ndi

Palibe kutentha, kusuta, kununkhiza kotentha kwa thiransifoma, ngakhale ulusi wa chubu la elekitironi ndi chubu la oscilloscope likuyatsa, ngakhale pali poyatsira kwamphamvu kwambiri, ndi zina zambiri.

2) Fufuzani malo ogwiritsira ntchito malo okhala ndi multimeter: njira yamagetsi yamagetsi yamagetsi, magwiridwe antchito a DC a semiconductor transistor ndi cholumikizira chophatikizira (kuphatikiza zigawo zikuluzikulu, zikhomo zamagetsi, mphamvu yamagetsi), mtengo wokana m'dera, ndi zina .imatha kuyeza ndi multimeter. Mtengo woyerekeza ukasiyana kwambiri ndi mtengo wabwinobwino, vutoli limatha kupezeka pambuyo pofufuza.

Mwa njira, malo ogwiritsira ntchito malo amodzi amathanso kuyezedwa ndi mawonekedwe olowetsera oscilloscope "DC". Ubwino wogwiritsa ntchito oscilloscope ndikuti kulimbikira kwamkati ndikokwera, ndipo mawonekedwe a DC akugwira ntchito komanso mawonekedwe amawu pamagawo oyesa ndipo zingasokoneze chizindikiro ndi phokoso lamagetsi ndizothandiza kusanthula zolakwika.

3) Njira yotsata siginecha: Pama circuits osiyanasiyana ovuta kwambiri, chizindikiritso cha matalikidwe ena ndi pafupipafupi choyenera chitha kulumikizidwa kumapeto omaliza (mwachitsanzo, ma amplifiers angapo.
