16 October 2017 Question by: Rapid Customer | Product code: 50-5366
Q. I am having a problem with this product proma photo resist board. I am using developer at 11.5:1 145 secs. exposure time etchant at 30% water on supplied solution 2 parts etchant 1part water. By the time the etch copper has been eaten away 30% of the image has gone to. Any help would be great as this is for GCSE projects.
A. Hi Dave, thank you for your question. We would recommend increasing the exposure time to between 2-3.5 minutes and look at a developer strength of 10:1 rather than 20:1.
