Monga novice pakupanga board kwa PCB, ndi chidziwitso chotani chomwe muyenera kudziwa?

Monga novice pakupanga board kwa PCB, ndi chidziwitso chotani chomwe muyenera kudziwa?Yankho:

1. Kuwongolera kwa mawaya: Mayendedwe a masanjidwe a zigawo ayenera kukhala ogwirizana momwe angathere ndi chithunzi chojambula.Mayendedwe a mawaya makamaka agwirizane ndi mawonekedwe a dera.Nthawi zambiri m'pofunika kuchita magawo osiyanasiyana pa kuwotcherera pamwamba pa ndondomeko kupanga.

2. Kukonzekera kwa zigawo ziyenera kukhala zomveka komanso zofanana, ndipo yesetsani kukhala okonzeka komanso okongola.

3. Kuyika kwa resistors ndi ma diode: ndege ndi yowongoka: (1) Kutulutsa kwapansi: Pamene chiwerengero cha zigawo za dera ndi zazing'ono ndipo kukula kwa bolodi la dera ndi lalikulu, nthawi zambiri kumakhala kosalala.(2) Oyimirira: Pamene chiwerengero cha zigawo zikuluzikulu ndi zazikulu ndipo kukula kwa bolodi la dera kuli kochepa, nthawi zambiri imakhala yoyimirira, ndipo kusiyana pakati pa mapepala awiriwa nthawi zambiri kumakhala mainchesi 1 mpaka 210.

4. Ikani potentiometer,
Mfundo ya mpando wa IC: (1) Potentiometer: Popanga potentiometer, zamakono ziyenera kuwonjezeka pamene potentiometer isinthidwa mozungulira.Potentiometer iyenera kuyikidwa mu kapangidwe ka makina onse ndi zofunikira za mawonekedwe a gululo, momwe zingathere pamphepete mwa bolodi, ndipo chogwiriracho chiyenera kutembenuzidwa kunja.(2) Mpando wa IC: Pankhani yogwiritsira ntchito mpando wa IC, m'pofunika kumvetsera mwapadera ngati mayendedwe a poyambira pampando wa IC ali olondola, komanso ngati mapini a IC ali olondola.

5. Kukonzekera kwa malo olowera ndi otuluka: (1) Malo olowera aŵiri oyenerera asakhale aakulu kwambiri, nthaŵi zambiri mainchesi 2 mpaka 310.(2) Kulowera ndi kutuluka kuyenera kuyang'ana mbali za 1 mpaka 2 momwe zingathere, ndipo siziyenera kukhala zosiyana kwambiri.

6. Popanga chithunzi cha mawaya, tcherani khutu ku dongosolo la zikhomo ndi kusiyana kwa zigawozo ziyenera kukhala zomveka.

7. Pansi pa malo owonetsetsa kuti ntchito ya dera ikuyendera, mapangidwewo ayenera kukhala omveka, waya wakunja ayenera kugwiritsidwa ntchito mochepa, ndipo mawaya ayenera kuyendetsedwa molingana ndi zofunikira.

8. Popanga chithunzi cha mawaya, chepetsani mawaya ndikuyesera kuti mizere ikhale yachidule komanso yomveka bwino.

9. M'lifupi mwa mzere wodutsa ndi katalikirana ka mizereyo zikhala zocheperako.Kutalikirana pakati pa mapepala awiri a capacitor kuyenera kukhala pafupi kwambiri ndi malo otsogolera a capacitor.

10. Chojambulacho chiyenera kuchitidwa mwadongosolo linalake, mwachitsanzo, kuchokera kumanzere kupita kumanja, kuchokera pamwamba mpaka pansi.
