Developing

Im using about 10g NaOH/l at room temperature.

 

Quirks:

- DONT use this Rösle Metal tweezers that i love to cook with. It has sharp ripples, while this is perfect for picking somethin in a hot pan it scratches the Photofilm wich leads to broken traces while etching....

 

- only develop until no more of this brown sludge comes off the PCB else you will erase everything

 

- throw the PCB in a huge can with water to immediately stop developing

Done
