Pcb bhodhi electro-goridhe inowana goridhe kuburikidza ne electrolysis, nepo kemikari goridhe inowana goridhe kuburikidza nemakemikari kuderedza kuita!

Zvichitaurwa zviri nyore, PCB electroplating goridhe, seimwe PCB electroplating, inoda simba uye rectifier. Kune akawanda marudzi emaitiro, anosanganisira cyanide-ine, asiri-cyanide masisitimu, uye asiri-cyanide masisitimu, akadai secitric acid mhando uye sulfite mhando. Ese asiri-cyanide masisitimu anoshandiswa muPCB indasitiri.

Kemikari yegoridhe (electroless gold plating) haidi kusimbiswa, inoisa goridhe pabhodhi kuburikidza nekemikari inopindira mune mhinduro.

Vane zvazvakanakira nezvazvakaipira. Pamusoro pesimba-pane asi kwete simba-pa, bhodhi rePCB rinogona kuitwa rakakora kwazvo, chero nguva yawedzerwa, yakakodzera mabhodhi ekubatanidza. Mukana wePCB kugadzira electro-goridhe potion kuraswa mudiki pane wemakemikari egoridhe. Nekudaro, iyo PCB yemagetsi yegoridhe inoda kubatanidzwa kubhodhi rose, uye haina kukodzera kunyanya mitsetse mitete.

Kemikari goridhe rinowanzo kutetepa (risingasviki 0.2 microns), uye kuchena kwegoridhe kwakadzikira. Mvura inoshanda inogona kuraswa chete kana ichishandiswa kusvika kumwero wakati.

Imwe ndeye PCB electroplating kugadzira nickel goridhe

Imwe ndeye kushandiswa kwesodium hypophosphite’s own oxidation-reduction reaction kuti igadzire nickel layer, uye inotsinhanisa kuita kugadzira goridhe layer (Uemura’s (TSB71 ine goridhe rakazvideredza)), inova nzira yemakemikari.

Ivy: Pamusoro pekuita misiyano pakati pePCB electroplating uye kunyudza goridhe, pane zvinotevera misiyano:

PCB electroplating goridhe layer yakakora uye yakaoma, saka inowanzo shandiswa kuvharisa nekupinza mativi anotsvedza, sezvigunwe zvegoridhe zvekuchinja makadhi;

Kunyudzwa goridhe rakanakira kukwirisa nekuda kwenzvimbo yakati sandara yepedhi uye inoshandiswawo pakusodha isina lead.
