The use of this photoresist is similar to a one-component mask with UV photo-curing.
Apply a certain volume to the prepared glass fiber laminate, press down through the lavsan film with glass, evenly "crush" into a thin layer.
Place on top a photomask and expose with an ultraviolet lamp. Recommended lamp
http://voron.ua/catalog/010686, as the most powerful and effective for amateur radio practice.
After exposure (on average 10 minutes, the time depends on the density of the photomask, the size of the board, the distance to the light source, the thickness of the clamp glass)
Wash off uncured photoresist. Development is not required !!! I washed off with a swab with isopropyl alcohol and washed off with liquid glass. Then rinse the board with water.
The results of using this photoresist for correcting the photoresist pattern after development are good, if a fragment of the track fell off at the time of development and washing.
We draw the fallen off area, expose with ultraviolet light, remove excess blots with a knife, if necessary, bathe with ultraviolet light and etch as usual. We poison the fee who is used to something :))))).
