Hi all,
I think this may be useful. As I receive the last batch of Flex PCB replacements, I took a couple of them to fix damaged 41's of my own.
When I was in the point of beginning with the bending process I realized that the sharp 90ยบ angles needed at (green) lines 1, 2, 3, 4, 5 and 8 will be far more easy to obtain if I pierced the Flex PCB along these green lines. (see picture)
Using a steel pin, carefully pierced between the tracks along the lines 1, 2, 3 & 4.
And about 1mm step along lines 5 & 8.
As a result the bending process is much more easy and the final shape is achieved and kept with more precision.
Best from Spain.
