PCB Pretreatment Processes

Cleaner SLOTOCLEAN S 20

Based on sulphuric acid, S 20 is a highly efficient thiourea-free cleaner for the removal of grease, oil and oxides from copper surfaces.

SLOTOCLEAN S 20 has exceptional wetting ability, making it an ideal cleaner for small blind via technology and is used regularly for the production of 80µm holes.

Cleaner SLOTOCLEAN S 20 PA

Based on phosphoric acid and supplied as a single concentrate, SLOTOCLEAN S 20 PA is ideal for the cleaning and activation of PCBs.

Because the product contains both surfactants and deoxidisers it is equally effective at removing both grease and copper oxide (with minimal copper attack of 0.5 to 1.0 ┬Ám per hour).

This cleaner is preferred in installation where jig stripping is less than ideal.

SLOTOCLEAN S 20 PA is free of complexing agents, alkylphenolethoxylates and AOXs.

SLOTETCH 584 Micro-Etch

A non-persulphate salt-based microetch for copper.

At low concentrations SLOTETCH 584 is ideal for finely etching the surface of thin copper deposits.
