Classic 500B - UI-Board should match better if LEDs are shifted by about 1.27mm

plewka opened this issue · comments

This is a mechanical tolerance issue only.

The rounded outline of the PCB is about 0.5mm too near to the cover of the rain sensor in wheel-to-wheel axis.
I had to use a Dremel to remove some plastics (~1mm) from that side of the rain sensor cover.

This is probably connected to another minor issue:
I didn't put the rubber to the board and mount it but found it much easier to put the rubber in place at the cover
and place the PCB to its position from top.
Maybe this is caused by a shift between the fixing holes and the grit of the LEDs, which are shifted ~1.27mm at my mechanics, too. The holes are big enough to tolerate this with some stress to the LEDs, but one can see the holes not matching perfectly before putting in the screws.

For my mechanics, the LEDs should be moved towards the side of the rain sensor drain in wheel to wheel axis to
solve both issues. For the current PCB it might be useful to tilt the LEDs a bit. At an updated PCB - to keep it universal -, a further area at the rounded area should be removed.
