…Advantage
The most important advantage of 308 nm excimer laser
debonding over other techniques is that it enables
utilization of polyimide based temporary adhesives
which can withstand exposure to temperatures as high
as 400°C.
This enables the bonded assembly to…

…The circuits are fabricated by vapor deposition of a uniform layer of metal (e.g., Au, Ag, Cu, Al) onto a flexible substrate such as PET, polyimide, PEN, or PMMA. The homogenized excimer beam is passed through a photomask, which is then re-imaged on this coated substrate. The high energy…
