As the ferric chloride etchant attacks tin, this is not suitable for tin or tin-lead
plated boards. This etchant is an aqueous solution of 28 to 42 per cent by weight
of ferric chloride. The solution has a specific gravity of 1.353 to 1.402. It operates
Process Control and Regeneration Hydrogen peroxide/sulphuric acid etchant is
used in immersion as well as spray etching operations. The process is controlled
by composition balance by recovery of copper sulphate as the by-product in ...
When the quantity of copper in the solution reaches its upper limit, a pump is
activated to replenish the etching solution and to simultaneously remove the
etchant until the desired density is achieved. The system is regenerated by
removal of ...
