Quality assurance

We stand for quality of your products...

...and it is guaranteed through the following procedures:

Test and qualification

Beside the mandatory EMC testing, all products run through further test and qualification procedures such as duration tests under fluctuations in temperature, density tests as well as funtional tests of hardware and software.

Tests for safety and special requirements are run together with external partners.

Visual inspection

The visual inspection of all series of electronic assemblies is processed through the Quins system from the manufacturer SLC. High resolution images are taken of the SMD assembly from both sides, which are then interactively compared with reference images.
Missing or misplaced components as well as bad soldering joints are reliably recognised.
In addition, the images of the assemblies through the manufacturing process are archived, a foundation for future traceablilty.

Microscopy for BGAs

Complex boards normally contain BGA housings ( Ball Grid Array ), a chip on a separate small PCB with solder balls on the back. By the soldering process approx. 500 connection points are smelted with the board.
The quality assurance of this process is required for each batch and each layer. A workplace with special microscopy provides powerful images of the often only 0.5 mm high solder area between BGA and PCB.
Compared with a conventional x-ray test, a test of the surface is possible to evaluate the solder form.

Electrical test

Product specific test fixtures are available for verification of all electronic properties. By complex assemblies such as CPU main boards, all the interfaces are tested in communication load. Similarly, tools are used to test the CPU core and the memory.
Normally a heat treatment of the assembly is included in the electrical testing procedure. Each series component runs through a pre-programmed 24 hours temperature process in the heating cabinet. Only following a completely successful final testing is the product released for delivery.

Documentation and traceability

Already before the start of production, each PCB has a unique number. This way all steps of production and manufacuring data can later be traced to a delivered end product.

Equipment assembly and final inspection

In our assembly department a completely electronic device is created from electronic components, cable sets and housings.

The trained staff knows all particularities in dealing with sensitive electronics and ensures that each screw is tightened in the right place.

After the final steps, such as functional testing, insulation measurements and customised configurations, your product is shipped.
