Recommended configuration of plated through holes
In addition to the hot-air-level (HAL), other PCB surfaces are getting more
important. Due to their different properties - such as mechanical strength
and coefficient of friction - we recommend the following configuration of
PCB through holes.

Circuit density
When using the specified diameter of the finished through hole according
to IEC 61 076-4-101 (0.6 ± 0.05 mm) with an appropriate annular ring, the
remaining distance between the rings is about 1 mm.
Under the condition that the width of the track and the space between
should be equal, two tracks of 0.2 mm width or three tracks of 0.14 mm
width can be placed between two rings.
Typical designs are shown in the drawing on the right side.

Derating diagram acc. to IEC 60512-5 (Current carrying capacity)
The current carrying capacity is limited by maximum temperature of
materials for inserts and contacts including terminals.
The current capacity curve is valid for continuous, non interrupted current
loaded contacts of connectors when simultaneous power on all contacts is
given, without exceeding the maximum temperature.
Control and test procedures according to DIN IEC 60512-5
Curve 1 shows raise in temperature
Curve 2 shows nominal derating
Curve 3 shows reduced values as per IEC512
