Pre Activation (MPB Pre Dip)
The main propose of this step is prevent of drog - in contamination particles to the activation bath. These particles can lead to the decomposition of the bath. They can drog - in from previous steps such as cleaner solution or miroetch.
The pre dip solution is nearby neutralized. furthermore its significant effect on the activation stability, it can use for replenishment activation bath when its density gets low.
Make up of this solution is easy and its concentration is not critical so there is no essential for analyze.
For replenishment the pre dip solution just add a percentage of initial material.
MPB Pre Dip is formulated as pre activation. this solution is used in immersion way and operate with it is so easy.
