We have just received a batch of assembled and raw flex circuit.
Therer is a new development created by Ignacio, our chief engineer. All flex circuits can lose adherence in hot or wet situations. This is critical on both extremes of the flex system. Therefore, we have created a several holes in each side and then we screw micro-screws on both sides of the flex, securing it forever in place.
Also we have further modified the base plastic to remove the last bending, the one that makes it more prone to peel off.
In a further blog I will post a picture of the screwed unit, with the flat "escape" bezel.
