PowerLamella Power Elements are the pluggable high current terminal blocks and spacers
of Würth Elektronik. PowerLamella is fully compatible with PowerRadsok. Reduce the assembly time of your service engineers or the efforts of your customers. Simply plug-in, no
screwing, done! Depending on the layout, currents of up to 400 ampere are possible.
Therefore Power Elements perfectly qualify as connecting elements for fuses, switches
and cables to the circuit board or as mounting elements.

Processing
Würth Elektronik PowerLamella Power Elements are pressed in into the circuit board. Soldering is not necessary. Therefore the PCBs are not exposed to temperature stress. This
processing step easily blends in to the processing chain and is highly cost efficient. With
the aid of the corresponding Press Fit tools, several Power Elements can be pressed in
simultaneously.

For assembling prototypes, no special equipment is required for pressing in,
a simple toggle press is sufficient
The circuit board needs support during the pressing procedure
The pressing force must be executed in a 90° angle to the circuit board
After the pressing process the pins should stand out of the drillhole
(approx. 0.2 – 0.5 mm)
Plated through holes of the circuit board must be executed
according to our indications
Cable shoes must be processed with adequate crimping tools

Circuit Board Design
For the massive Press Fit Technology the PCBs are to be finished according to the Würth
Elektronik ICS Press Fit specifications (see table on the side). Particular attention should be
paid to the drill diameter and the copper thickness. Due to the different layer thicknesses
of Hot Air Levelling compared to chemical surfaces, the final diameters vary.

The current carrying capacity of a Press Fit connection needs to be seen in the context of
the overall system. The Press Fit zone has a very low electrical contact resistance of
100 – 200 µOhm. The limiting factor therefore usually lies in the circuit board layout or in
the connection of a feed line. The plugging elements have an electrical contact resistance
of 0.2 mOhm at Ø 3.6 mm, 0.09 mOhm at Ø 6.0 mm and 0.05 mOhm at Ø 10.0 mm.
