A sodium-hydroxide free PCB developer that is supplied in free flowing odourless granules & is ready for dilution with water. Suitable for single or double sided PCBs & all applications such as prototype work is 10g of granules with 100ml of water or the full 250g would make up to 2.5 litres of developer. The ideal temperature for dilution & developing is room temperature i.e. Approx. 20 C. Development time will depend on the complexity of the board design dilution ratio of the solution & the temperature. After development the board should be rinsed thoroughly & dried either in air or an oven. Always wear protective gloves & goggles & avoid contact with the eyes & skin but in case of contact flush liberally with water.
