After the diaphragm has been fully applied and is wrinkle-free . . .
. . . tape is applied across the parts where the "spars" are in order to protect those areas from . . .
. . . the conductive "wash" that is applied . . .
. . . over the full length of the panel. The wash is applied to fill in any micro-cracks that might have occurred when the diaphragm was stretched.
After the conductive wash, the tape is removed from the spar areas, leaving . . .
. . . those parts of the diaphragm non-conductive.
Additional tape is added on the stators' edges, and the front stator is then placed over top and pressed firmly into place.
Excess diaphragm material is cut from the edges.
The assembled electrostatic panels are then placed in a vacuum-forming machine . . .
. . . for 30 minutes, activating the VHB tape and "locks" the assembled panel into place.
