Positioning control PosCon 1900

A constant, defined contact force of the soldering tip on the substrate is essential in automated ultrasonic

soldering. Therefore, a reproducible, precise control of the contact force of the soldering tip to the substrate is

necessary for perfect soldering results.

For this specific purpose, the PosCon 1900, a self-contained, motorized Z-axis, has been developed to

accommodate the ultrasonic robot soldering heads # 9200-127 and # 9500-127. With constant soldering tip

force, the system can automatically compensate, substrate height differences of up to +/- 15mm.

The complete PosCon 1900 system axis consists of three parts:

1. Motorized Z-axis with a path of +/- 15mm. The electronic motor controller with height control is

integrated in the housing

2. Leaf spring mounted soldering head holder (support). Oprtion: Fixing element for solder wire feed.

3. Electronic Height measurement with LED bargraph display. Leaf spring center position corresponds to

the center of the electronic measuring device (green LED). The electronic display of the measuring

system comprises 21 LEDs and corresponds to a mechanical way of the spring device of a total of 0.6

mm. Each 0.3mm upwards corresponds to 10 yellow LED and 0.3mm down also 10 yellow LED. Thus, we

achieve a mechanical resolution of only 0.03mm (30祄) per LED increment, which allows a precise and

very fine control of the system

In controlled operation, the motorized part of the axle travels downwards or upwards as required, so that the

height measuring system always remains in the middle = green LED. This guarantees a constant force on the
