Product overview

• Single sided copper clad SRBP board coated with a positive photo-resist • Suitable for use with our UV exposure box• Covered with light-proof protective film, which should not be removed until the board is used

The PCB should be exposed using our UV exposure box and a circuit overlay transparency. Exposure time will be from 8 to 15 minutes. Mix together 0.5 litres approximately with one teaspoonful of sodium hydroxide (available from most chemists) and pour into a tray (CH38R). Gently rock the exposed PCB in the tray until the unwanted photo resist is dissolved away. Etch the board in a bath of ferric chloride and after rinsing, expose the PCB in the UV box for a further 10 minutes. Wash off all the remaining etch resist in a tray of sodium hydroxide solution.
