Birao PCB electro-gold obtains gold through electrolysis, while chemical gold obtains gold through chemical reduction reaction!

Simply put, PCB electroplating gold, like other PCB electroplating, requires power and a rectifier. There are many kinds of processes, including cyanide-containing, non-cyanide systems, and non-cyanide systems, such as citric acid type and sulfite type. All non-cyanide systems are used in the PCB industry.

Ny volamena simika (plating volamena tsy misy elektrônika) dia tsy mila hery, mametraka volamena eo amin’ny solaitrabe amin’ny alàlan’ny fanehoan-kevitra simika ao amin’ny vahaolana.

Samy manana ny tombony sy ny fatiantokany izy ireo. Ho fanampin’ny herinaratra fa tsy mandeha, ny birao PCB dia azo atao matevina be, raha toa ka mihalava ny fotoana, dia mety amin’ny boards. Ny vintana amin’ny famokarana PCB electro-gold potion nariana dia kely kokoa noho ny volamena simika. Na izany aza, ny volamena elektrika PCB dia mila mifandray amin’ny birao manontolo, ary tsy mety amin’ny tsipika manify manokana.

Ny volamena simika dia manify amin’ny ankapobeny (latsaky ny 0.2 microns), ary ambany ny fahadiovan’ny volamena. Ny fluid miasa dia tsy azo ariana raha tsy ampiasaina amin’ny lafiny iray.

Ny iray dia ny electroplating PCB mba hamoronana volamena nikela

Ny iray dia ny fampiasana ny sodium hypophosphite ny oxidation-reduction fanehoan-kevitra mba hamorona ny nikela sosona, sy ny fanoloana fanehoan-kevitra mba hamoronana sosona volamena (Uemura’s (TSB71 dia miaraka amin’ny tena nihena volamena)), izay fomba simika.

Ivy: Ho fanampin’ny fahasamihafan’ny fizotran’ny PCB electroplating sy ny volamena asitrika, dia misy ireto fahasamihafana manaraka ireto:

PCB electroplating sosona volamena dia matevina sy mafy kokoa, noho izany dia matetika ampiasaina amin’ny plugging matetika sy ny fampidirana sliding faritra, toy ny volamena rantsan-tànany ny switch karatra;

Ny volamena asitrika dia tsara apetraka noho ny fisaka amin’ny pad ary ampiasaina amin’ny fametahana tsy misy firaka.
