Product description: B327 - 100g etching machine
Printed circuit board etching agent. It is an alternative to iron chloride. It dissolves very quickly and does not crystallise from the solution. It etch evenly, ensuring sharp contours and minimising pickling.
How to use the B327 pickler
Dissolve the preparation in 0.5 l of water at about 50°C. Digest at 40 °C (max. 50 °C). Bathing movement ensures faster digestion. The pickling agent solution must not be stored in hermetically sealed containers due to the danger of overpressure and cracking.
