HP41c upper post repair

We have applied the same solution that we created for the lower posts to the upper posts: a grip that clips on the keyboard circuit, and strengthtens the grip with the introduction of the screws. 

In the case of the upper posts there was a requirement to drill anyway - so it doesn't change the original procedure. But the piece has the same 3-petal grip that we use for the lower post:

The connection strengthtens when the screw is put in, since it makes pressure to the sides of the post and makes sure it doesn't move. We plan to put it in production already!!
