Advanced Solutions for Printed Circuit Board Manufacturing. Technic is a leading provider of plating process solutions to the electronics industry. Smaller, faster, and lighter have always been major drivers in the printed circuit board (PCB) ''s trends in manufacturing and legislation have made both cost and environmental concerns equally important factors in PCB production.
gold stripping solution in a dry form and upon dissolving in water adding cyanide, it worked very nicely to strip gold layers from semiconductors without damaging the substrate. Time 1 minute 30 seconds for gold fingers electronic circuit board. Gold will be made into a solution.
Prepare the stripping solution. With your gloves ON, add enough water to a large frying pan to cover the board and then add about three tablespoons of sodium hydroxide. Slowly heat the solution on the stove, then place your board inside. After a few minutes of simmering, the blue parts will detach from the board.
In order to recover valuable metals and regenerate the etching solution from the spent nitric etching solutions of printed circuit board (PCB), solvent extraction, stripping, electrowinning, precipitation and cementation experiments have been performed.
A method of stripping silver from a printed circuit board without attacking the underlying base metal. The stripping solution comprises an oxidizing agent, an alkaline pH adjuster, and a silver solubilizing agent. After the silver has been sufficiently removed from the surface of the printed circuit board, the printed circuit board is contacted with a neutralization solution to remove any smut ...
The solution strips the tin/lead alloy from the tabs of the printed circuit board until the copper shows as a pink bright metal. There is no attack on the copper itself. The nonperoxide solder stripping solution particularly lends itself to spraying as opposed to a dipping procedure.
Typical applications include anodizing, plating, painting, cleaning, etching, powder coating, and racks for printed circuit boards. If you''re interested in a new rack, basket or fixture, we can design a protoype.

Because developing is apparently so simple, it is easy to overlook its significance to the production of high quality PCB''s, and to overlook the details necessary to produce high quality developing. The standard developer today is a 1% solution of either Sodium Carbonate Monohydrate (), or Potassium Carbonate (K2CO3).
Apr 28, 2017· Most of us must have heard about the Printed Circuit Board (PCB) design process. But very few are aware about the details. This post will put some light upon various stages in the PCB design process, but will focus more on the stripping and etching process of a PCB.
