Dear Sir,
I would like to ask about using Forturn glass. If someone has done it,
please reply me which one
process should I improve?
My process sequence using quartz mask is as follows:
(1) UV Exposure
UV wavelength: 312nm
Intensity: 2.7mW/cm2
Exposure time: 12 mins
(2) Heat Treatment
20¢J ~ 500¢J for 1 hour, temperature ramping up at 40¢J/min
500¢J ~ 600¢J for 1 hour, temperature ramping up at 28¢J/min
The results are that all of the exposed and unexposed areas turned into
burnt yellow
and no pattern appeared.
Could you please tell me what kind of ceramic material I should choose for
heat treatment,
and whether the temperature ramp is too high and the light source is
appropriate?
I would appreciate your early reply.
Yours sincerely,
Chonglong Chang
