The utility model relates to circuit board
nickel gold technical field, specifically disclose
printed circuit board gold immersion is used full -enclosed automatic chemical
nickel gold device, including closed storehouse, the top inner wall of closed storehouse is provided with mobile clamping
assembly, and the inside left side of closed storehouse is provided with circulating
nickel plating
assembly, mobile clamping
assembly is used for clamping circuit board and processes, and circulating nickel plating assembly is used for nickel plating to circuit board, through to nickel plating groove is divided into three -segment mode, and every
pool is provided with first heating
pipe and
thermocouple, and carries out accurate
temperature control, and the temperature in every
pool gradually increases and forms the heating of subregion, can make
gold layer pore reduction on the surface of circuit board, and cooperate with the fixed
pipe and venturi
nozzle set up in bottom, make three -dimensional end flow in nickel plating groove, eliminate the dead angle that conventional nickel plating cannot deposit, can keep nickel
layer thickness balance, improve the deposit uniformity of circuit board, improve circuit board quality and reliability.
