Does anyone have any experience with spraying + photo resist on to pcbs?
When i use commercially coated boards, i get really good results, however when i spray my own, the caustic soda just rips off all the coating during developing.
Also I cant seem to achieve a consistent coating. speckles appear all over the surface, like if you were spraying water onto a water proof surface.
Id really like to use the spray, as its much cheaper than buying the ready sprayed ones.
Many thanks,
