Dear friend,
I have been making PCB for my prototypes and test projects using Laser print & heat transfer method.
I was able to make PCBs using this method successfully , for tracks with good width.
now I propose to make PCB with some fine tracks, for which this method is not so successful and I propose to shift to photo sensitive method.
Here in India photo sensitised blakn PCB is not available or to get sensitising spray from abroad is not posible.
Can any one suggest from where I can get a detailed information for making the PCB photo sensitive, using easily available chemicals.
Thank you members
