Advantages of the VADUs

Plants and systems for void-free soldering with vacuum

Icon Temperature

Short cycle times and high performance by intelligent temperature management

The VADU systems have a short heating and cooling time with controlled gradients and a process temperature of up to 400 °C. In addition, temperature stability is secured during evacuation.

The substrate temperature is continuously monitored and controlled with an intelligent temperature regulation contacting the docking heating and cooling plate. This technology provides optimum soldering processes with short cycle times, fast soldering results and high performance.

Icon Environment

Environment-friendly and easy to operate due to a smart design

Based on the compact design, the VADU soldering systems require a minimum of space and energy and are both economically and ecologically efficient during a 24/7 operation.

The ergonomic design of the VADU also provides advantages with regard to operation, service and maintenance due to an easy and quick access to the chambers.

Icon Individual customer demands

Flexible soldering technologies for individual customer demands

PINK offers soldering systems suitable for each production strategy: VADU100 for laboratory or batch production, VADU200 for batch operation or VADU300 and VADU400 as automated inline systems for series production.

Each vacuum soldering system for preform and/or paste soldering under an inert soldering atmosphere can be equipped according to individual customer requirements with different customized options like e.g. formic acid equipment, transfer systems, handling equipment, etc.

Icon Process control

Perfect and reproducible soldering results due to a continuous process control

All systems of the VADU series provide an individual definition as well as control and monitoring of the soldering profiles due to permanent product tracking and process control.

All process data can be tracked at any time due to a permanent parameterization during the soldering process. Therefore, reproducibility of the soldering processes is guaranteed and a constant high product quality is assured.
