Temperature control

PCB boards have tight tolerance values during the soldering process. Uncontrolled heat leads to solder evaporation and oxidation - rapid or slow cooling causes distortions, cracks, and defects in the crystal structure. Without controlling the temperature, rejects are inevitable.

The temperature control sensor system precisely regulates the local heat input. You will get clean solder joints without any additional cleaning and the number of rejects will drop significantly. The system flexibly adjusts parameter for different materials.

Laser surface hardening requires extremely precise temperatures. Temperatures that are too low result in incomplete hardening, while temperatures that are too high can cause distortions, cracks, or unwanted microstructural changes. To avoid rejects or post-processing, the temperature is often adjusted manually, which increases the production time.

The sensor system continuously measures the surface temperature during the laser process and automatically adjusts the laser power. This keeps the temperature within the optimum range. This allows you to create stable processes with reproducible results.

During laser case hardening of tools, uncontrolled temperature spikes can occur, leading to deformations and tolerance deviations. This increases wear and shortens the durability of the tools. Manually monitoring the temperature during the production process is time-consuming and expensive.

The sensor system monitors the temperature at critical positions in real time and adjusts the laser power accordingly. Predictive data analysis detects overheating in advance. This will help prevent deformations, reduce rework, and increase throughput.

During the hardening process of turbine wheels, the energy of the laser beam is often distributed unevenly, depending on the geometry and surface structure. Overheating in one area and rapid cooling in another can lead to distortions and cracks, which impair the efficiency of the turbine engine. Without effective monitoring, high-quality results are therefore difficult to reproduce.

The sensor system accurately measures the temperature in the curing zone and automatically adjusts the laser power accordingly. The optimum curing temperature remains constant ensuring the surface is protected, the throughput time is increased, and quality is guaranteed to meet the most stringent air and aerospace requirements.

Plastic components such as housings, plugs, and sensors require precise welding temperatures. Temperatures that are too high cause material deformations and damage, while temperatures that are too low cause an incomplete bond. Contaminants or variations in the glass fiber cladding content further exacerbate the problem.

The sensor system for temperature control continuously measures the temperature in the fusion zone and automatically adjusts the laser power accordingly. Contaminations and material variations are detected reliably. You thus consistently achieve dense, high-quality welded joints without rejects.
