DS-44 is a carbonate based, liquid developer concentrate for developing fully or semi aqueous dry films and/or liquid photo imaged solder masks. DS-44 contains a chemical stabilizer and optional cleaners. Unlike conventional stabilizers, the PC-Series stabilizers do significantly increase the pH of the solution, and thus can be employed at concentrations high enough to obtain 15-20% more throughput through the same volume of chemistry.
This economical concentrate can also be employed in manual or automated replenishment systems. When used in combination with SEACOLE’S PC-AUTO/Controller and Dosing Device, the DS-44 Developer bath may be operated for 4-20 weeks continuously and without dumping (depending upon throughput). The PC-AUTO/Controller will automatically make additions of developer concentrate and water, maintaining the pH at +/-0.02 pH units and the carbonate concentration at +/-0.03% by weight, resulting in predictable developing quality without adjusting the conveyor speed.
- DS-44 is formulated with a unique hard water scale inhibitor which will not dull fused solder during LPI solder mask processing.
- DS-44 is compatible with virtually all type of aqueous and semi aqueous dry films and LPI solder masks.
- DS-44 is stabilized, improving process consistency and improving bath life by 20%.
