Kodi kusunga PCB Board?

1. pambuyo kupanga ndi processing wa PCB, zingalowe ma CD ayenera kugwiritsidwa ntchito kwa nthawi yoyamba.Payenera kukhala desiccant mu thumba lakuyika vacuum ndipo zoyikapo zili pafupi, ndipo sizingagwirizane ndi madzi ndi mpweya, kuti mupewe kutenthedwa.reflow uvunindi khalidwe mankhwala anakhudzidwa ndi malata kutsitsi padziko PCB ndi makutidwe ndi okosijeni wa solder PAD.

2. PCB iyenera kuyikidwa ndikulembedwa m'magulu.Pambuyo pa kusindikiza, mabokosiwo ayenera kupatulidwa kukhala makoma, ndipo sayenera kuwonetsedwa ndi dzuwa.Iyenera kusungidwa mu kabati yolowera mpweya wabwino komanso youma yokhala ndi malo abwino osungira (kutentha: 22-27 madigiri, chinyezi: 50-60%).

3. kwa matabwa PCB dera amene si ntchito kwa nthawi yaitali, ndi bwino potsuka pamwamba pa matabwa PCB dera ndi atatu umboni utoto, umene ungakhale chinyezi, fumbi ndi odana ndi makutidwe ndi okosijeni, kuti moyo yosungirako wa matabwa ozungulira PCB akhoza ziwonjezeke kwa 9 miyezi.

4. Chigamba cha PCB chosapakidwa chikhoza kusungidwa kwa masiku 15 pansi pa kutentha kosalekeza ndi chinyezi, ndipo osapitirira masiku atatu pansi pa kutentha kwabwino;

5. PCB iyenera kugwiritsidwa ntchito mkati mwa masiku atatu mutatulutsa.Ngati sichinagwiritsidwe ntchito, sunganinso thumba lokhazikika.

6. The PCBA bolodi pambuyomakina a SMTimakwezedwa ndipo DIP iyenera kunyamulidwa ndikuyikidwa ndi bulaketi ya antistatic.
