Developer Pack (50gm) DP-50 For Photo Resist PCB
A bag of DP-50 developer is mixed with 1 litter of 25°C water.
The exposed PCB is gently agitated in solution. The exposed areas of
resist will dissolve into the solution, leaving the green resist in
areas that were not exposed to UV light.
If the resist does not fully remove from the exposed areas, the UV
received was insufficient. Possible causes are: Insufficient exposure
time; the UV source is old and not producing enough UV; incorrect UV
frequency (use 350~450µm UV source); the artwork is not UV transmissive.
When the DP-50 solution no longer develops the resist in a timely
manner, it can be neutralized for safer disposal using the Kinsten BV5
kit, converting the developer to a gel for easy disposal.
This Pack can be used for 400cm2 PCB size area.
