Pcb bhodhi pini yemagetsi goridhe uye nickel kunyura musiyano wegoridhe?

Pcb board board yegoridhe inowanikwa kuburikidza neelectrolysis, uye goridhe inowanikwa kuburikidza nemakemikari ekuderedza kuita!

Ndeupi musiyano pakati pcb yemagetsi goridhe uye yakanyura nickel goridhe.

Kuti uzviise zvakapusa, pcb electroplating goridhe, senge imwe pcb electroplating, inoda magetsi uye kugadzirisa. Kune akawanda marudzi ehurongwa hwayo, kusanganisira cyanide, isiri-cyanide system, isiri-cyanide system uye citric acid, sulfite zvichingodaro. Inoshandiswa muPCB indasitiri isiri-cyanide masisitimu.

Ndarama-yakanamirwa (chemakemikari yegoridhe-yakanamirwa pamvura) haidi magetsi, asi inoisa goridhe kumusoro kuburikidza nekemikari inoitika mumhinduro.

Ivo vane zvavo zvakanakira nekuipira. Pamusoro pekuti inoiswa simba kana kwete, pcb bhodhi goridhe rinogona kuitwa rakakora kwazvo. Chero bedzi nguva ichiwedzerwa, inokodzera kugadzira mabhodhi akasungwa. Mukana wekurasa wePBB yemagetsi emagetsi ishoma pane yegoridhe. Nekudaro, pcb system inoda iro rese bhodhi kuitisa, uye haina kukodzera kugadzira yakakosha mitsara.

Goridhe mineralization inowanzoonda zvakanyanya (isingasviki 0.2 micron) uye kuchena kwegoridhe kwakaderera. Kushanda mvura inogona kungoraswa kune imwe nhanho.

Imwe ndeyePCB yakakwenya kugadzira nickel goridhe

Imwe ndeye kushandiswa kwesodium hypophosphite self REDOX reaction yekuumba nickel layer, iko kushandiswa kwekutsiva kugadzirisa kuita goridhe layer (kamura (TSB71 iri nega inoderedza goridhe), inzira yemakemikari.

Ivy: Pamusoro pekusiyana kuri kuitika kwePCB electroplating nekurongedza, pane misiyano inotevera:

Pcb electroplated goridhe yakatetepa iri gobvu, kukwirira kuomarara, saka inowanzo shandiswa kune yakajairika plug plug inotsvedza chikamu, senge switch kadhi yegoridhe munwe, nezvimwe.

Iyo inoshandiswawo kune isina lead-isina waya yekutenderera nekuda kwenzvimbo yakatsetseka yepad.
