This product is used as the developer on positive photo-resist printed circuit boards. Includes instructions. 50 gram package, mixes with water, makes 1 quart.

Product Future:

For developing positive photo-resist printed circuit boards
Net Weight: 50g
Can develop 480 inche² (or 3000 cm²) of single sided positive photoresist PCB

Instructions:

Mix powder with one quart of water in a plastic container.
Develop board (in a dark room):
Insert the board into the solution copper side up. The goal here is to remove all of the resist (coating) that was exposed to UV light. Once the resist is removed these areas will be down to bare copper.
You can agitate the board or container to develop it faster.
Rinse the circuit board in cool water. Be sure that all of the previous solution is cleaned off the board.

Notice:

Solution Temperature: 15^oC~30^oC, higher temperatures will result in faster developing, but never ever exceed >30^oC.
NEVERt use the same container for developing and etching.
The developing time will be increased one after each successive board is developed.
