or 6-10g/l of Sodium or Potassium Hydroxide. Conduct trials if in doubt.
Approvals
UL, CSA (K130 and above)
Photoresists & Copper-Clad Boards
Printed circuit board materials for the manufacture of high quality PCBs
Standard high quality glass-epoxy FR4 substrate and glass-APPE substrate specifically for high frequency applications
Where applicable, the resist coated boards are exposed using UV light before being developed with half-strength Universal Developer solution and finally etched using a solution of Ferric Chloride Hexahydrate Crystals. Pre-sensitised with positive working photoresist.
