Definitions
- the studs 12 can be given a height, depending on the case, between a few hundredths and a few tens of millimeters for a diameter and a spacing of the order of a few tens of millimeters. Tests have been carried out by forming pads 50 ⁇ in height and 0.7 mm in diameter, spaced 0.8 mm apart, the results of which have proved to be extraordinarily satisfactory, namely that the contact resistance in the connection between the conductive area thus obtained and another normal area conductive area was reduced by more than half.
