Premanufactured

These materials work well...

Substrate

• Variety of presensitized copper clad board from mouser. Datasheet.

Developer Chemicals

• Positive Developer Chemical - Compatible with above presensitized copper clad board.

Raw

Starting from raw materials may be cheaper and doable, but has yet to be thoroughly tested.

Substrate

• 5 x 8 Scissor Cut Ultra Thin Copper Clad - Cheap for Photolithographic PCB Fab
• 10x 6x8" Photosensitive Dry Film Sheets

Developer Chemicals

• Sodium Carbonate Washing Soda. May not be suitable for processing positive resists.

Positive developer chemicals apparently use a Sodium Hydroxide and Sodium Silicate mixture. This may reliably permit deep development without overdependent of unexposed regions.
