Ultraviolet ray exposure equipment


It uses the ultraviolet rays to bake the pattern on the positive exposure printed board.
The ultraviolet rays of the sunbeam can be used, too.
However, because the strength depends on the weather, it isn't suggested to.
To use the fluorescence light is easy.

In the look, it doesn't understand the branding condition. Because it is, you decide the time and irradiate the ultraviolet rays, and it develops and confirm the condition. The about 20 minutes are suitable as much as 5 cm in the distance between the fluorescence light and the printed board in the case for the fluorescence light of 10 W. To try at first, being the one to have cut the positive exposure printed board small and to find the appropriate time are safer. The equipment to introduce to this place is the equipment which irradiates the ultraviolet rays only in the constant time, combining the fluorescence light and the timer. There was a marketing article, too, but I did the own composition. The fluorescence light circuit is the same as usual fluorescence light desk stand. I use the count-down timer for the timer circuit and am made to be able to adjust the time of the exposure from the 1 minute to the 99 minutes.
