PC 450 is a carbonate based, liquid developer concentrate for developing fully or semi aqueous dry films and/or liquid photo imagable solder masks. Unlike conventional stabilizers, the PC-Series stabilizers do significantly increase the pH of the solution and can be employed at concentrations high enough to obtain 15-20% more throughput using 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 PC-Series Developer baths 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.
