Pali njira zina popanga ma board amagetsi a LED. Njira zoyambira pakupanga ma board ozungulira a LED: kuwotcherera-kudziyang'ana-mutual kuyendera-kuyeretsa-kukangana

1. LED dera kuwotcherera bolodi

① Chiweruzo cha njira ya nyali: kutsogolo kumayang'ana mmwamba, ndipo mbali yomwe ili ndi rectangle yakuda ndiyo mapeto oipa;

②Mayendedwe a bolodi lozungulira: kutsogolo kuli koyang'ana mmwamba, ndipo mapeto ali ndi ma doko awiri amkati ndi kunja ndi ngodya yakumanzere;

③ Chiweruzo cha mayendedwe a kuwala mu bolodi lozungulira: kuyambira pakuwala kumtunda kumanzere (kuzungulira kozungulira), kumakhala kolimbikitsa → zabwino → zabwino → zabwino ndi zoipa;

④ Kuwotcherera: Weld mosamala kuti muwonetsetse kuti cholumikizira chilichonse cha solder ndi chodzaza, choyera, ndipo palibe solder yosowa kapena yosowa.

2. LED dera board kudzifufuza

Mukamaliza kugulitsa, fufuzani kaye ngati zolumikizira zogulitsira zili ndi zolumikizira zabodza, zosokonekera, ndi zina zambiri, ndiyeno gwirani ma terminals abwino ndi oyipa a board board ndi multimeter (zakunja zabwino ndi zoyipa zamkati), onani ngati magetsi anayi a LED akuyaka nthawi imodzi, ndikuchita Sinthani mpaka matabwa onse ozungulira azitha kugwira ntchito moyenera.

3. Kuyang'ana pamodzi kwa matabwa otsogolera otsogolera

Pambuyo podzifufuza, iyenera kuperekedwa kwa munthu amene akuyang'anira kuti aunikenso, ndipo ikhoza kuyenda munjira yotsatira ndi chilolezo cha munthu amene akuyang'anira.

4. Kuyeretsa bolodi la LED

Sambani bolodi ndi 95% mowa kuti muchotse zotsalira pa bolodi ndikusunga bolodi loyera.

5. Kukangana kwa bolodi la LED

Chotsani matabwa oyendera magetsi a LED pa bolodi lonse limodzi ndi limodzi, gwiritsani ntchito sandpaper yabwino (coarse sandpaper ngati kuli kofunikira, koma ndi chilolezo cha munthu amene akuyang'anirani) poya ma burrs pambali pa bolodi la dera, kuti bolodi lozungulira likhale lokhazikika bwino Mkati (kuchuluka kwa mikangano kumadalira chitsanzo cha mwiniwake).

6, kuyeretsa bolodi lotsogolera

Tsukani bolodi la dera ndi mowa wa 95% kuti muchotse fumbi lomwe latsala pa bolodi la dera panthawi yachisokonezo.

7, waya wotsogolera dera lotsogolera

Lumikizani bolodi lozungulira ndi waya woonda wabuluu ndi waya woonda wakuda. Malo ogwirizanitsa pafupi ndi bwalo lamkati ndi oipa, ndipo mzere wakuda umagwirizanitsidwa. Malo ogwirizanitsa pafupi ndi bwalo lakunja ndi abwino, ndipo mzere wofiira umagwirizanitsidwa. Mukamapanga mawaya, onetsetsani kuti waya walumikizidwa kuchokera kumbuyo kupita kutsogolo.

8. LED dera board kudzifufuza

Onani mawaya. Pamafunika kuti waya uliwonse udutse pa pad, ndipo kutalika kwa waya kumbali zonse ziwiri za padiyo kuyenera kukhala kwaufupi momwe kungathekere pamwamba, ndipo waya wochepa thupi sudzathyoledwa kapena kumasuka pamene kukoka mopepuka.

9. Kuyang'ana kwapang'onopang'ono kwa matabwa oyendetsedwa

Pambuyo podzifufuza, iyenera kuperekedwa kwa munthu amene akuyang'anira kuti aunikenso, ndipo ikhoza kuyenda munjira yotsatira ndi chilolezo cha munthu amene akuyang'anira.

10. Ma board otsogola apamwamba kwambiri

Ganizirani mizere pa mbali ya bolodi la dera la LED molingana ndi mzere wa buluu ndi mzere wakuda, ndikulimbitsa nyali iliyonse ya LED ndi magetsi a 15 mA (voltage imakhala yosasinthasintha, ndipo panopa imachulukitsidwa). Nthawi yokalamba nthawi zambiri imakhala maola 8.
