POLY/Solv RR-24 / RR-24 Replenisher is formulated to be used as a polishing or re-work step when photo resist has become trapped on printed circuit boards. RR-24 / RR-24 Replenisher will dissolve residual dry film that is left after initial resist stripping processes and has been rinsed and dried.
- Will not attack base copper, tin, or tin/lead plating.
- Provides flexibility to rework printed circuit boards.
- Helps to eliminate copper shorts in subsequent etching processes.
