Yathunthu PCB Njira yopangira ma electroplating imaphatikizapo chithandizo chotsatira cha electroplating. Mwachidule, ma electroplating onse amathandizidwa pambuyo poti adasankhidwa. Chithandizo chophweka kwambiri pambuyo pochizira chimaphatikizapo kuyeretsa ndi kutentha madzi otentha. Coat

Momwe mungachitire ndi PCB mutatha kusankhidwa

Njira zochizira pambuyo pogona zitha kugawidwa m’magulu 12 awa:

1, kuyeretsa;

2, youma;

3, kuchotsedwa kwa hydrogen;

4, kupukuta (kupukuta kwamakina ndi kupukuta kwamagetsi);

5, kupitirira;

6, mitundu;

7, kupaka utoto;

8, kutsekedwa;

9, chitetezo;

10. Kujambula;

11, osakwanira coating kuyanika kuchotsa;

12, kusamba kuchira.

Malinga ndi kagwiritsidwe ntchito kapangidwe kazitsulo kapena zinthu zosapanga dzimbiri zamagetsi, chithandizocho chimatha kugawidwa m’magulu atatu, monga kukonza kapena kupititsa patsogolo chitetezo, kukongoletsa ndi magwiridwe antchito.

(1) Kuteteza mukamalandira chithandizo

Kupatula zokutira kwa chrome, zokutira zonse zoteteza, zikagwiritsidwa ntchito ngati zokutira pamwamba, ziyenera kuthandizidwa moyenera pambuyo pake kuti zisunge kapena kupititsa patsogolo chitetezo chawo. Njira yodziwika kwambiri yothandizira pambuyo pake ndi passivation. Pofuna kuteteza zofunikira pakukongoletsa pamwamba, mwachitsanzo, kuphimba kapangidwe kake, kutetezedwa kwachilengedwe ndi malingaliro amitengo, atha kugwiritsa ntchito zokutira zowonekera pamadzi.

(2) chithandizo chokongoletsera positi

Mankhwala okongoletsera pambuyo panu ndi njira yodziwika bwino yopanda chitsulo. Mwachitsanzo, kuyala kwa golide wonyenga, siliva wonyenga, mkuwa wachikale, kutsuka, utoto kapena utoto ndi njira zina zaluso. Mankhwalawa amafunikiranso kuti pamwamba pake azikutidwa ndi zokutira zowonekera. Nthawi zina amagwiritsa ntchito chromatic mandala wokutira ngakhale, mwachitsanzo kutengera aureate, ofiira, obiriwira, ofiirira kudikirira utoto wokutira.

(3) Yogwira ntchito pambuyo pokonza

Zina zosapanga dzimbiri zopangira ma electroplating zimapangidwa kuti zizigwira ntchito, ndipo chithandizo china chofunikira chimafunika pambuyo pa electroplating. Mwachitsanzo, monga coating kuyanika pamwamba wosanjikiza maginito kutetezedwa, monga pamwamba solder coating kuyanika wa coating kuyanika kuwotcherera, etc.
