NATRIJUM PERS.100
Natrijum persulfat, B327, za izradu štampanih pločica, 100grama za 0.5l vode
Sodium persulfate B327, a compound for etching of printed circuit boards and pickling of copper. An ideal alternative to ferric chloride. It is readily soluble and does not crystallize from the solution. It etches evenly, ensures the sharpness of contours and minimizes undercutting.
Usage: Dissolve the preparation 0.5 liter of water per 100 grams of sodium persulfate, at a temperature of 50°C. Perform etching at 40°C (max. 50°C). Bath movement ensures quicker etching. The etching solution must not be stored in hermetically sealed containers due to the risk of developing overpressure and cracks.
