Base Material

We offer the right base material for any application. Our material is characterized by high resistance and at the same time long-term durability at the brazing process. Short-term temperatures of almost 300 °C can be handled without any problems.

You will find further information on the data sheets. We will be pleased to advise you with your individual application.


The increasing pack density of components on both sides requires increasingly demanding soldering mask designs. There, the common composite material can reach its stability limit. As an alternative, titanium provides extreme resistance and at the same time very high abrasion resistance and insensitiveness against flux and solder for designs with and without SMD-pouch. To separate SMD from very closely located THT-solder joints titanium is (the?) first choice – thickness of up to 0.3 mm can be realized. The temperature connectivity to the circuit board is also considerably better when using titanium. Titanium inserts can be implemented in almost every soldering system.

Please feel free to contact us!


All the named base material can be finished with our ESD-suited coatings. This make longer service periods with better tin flows and reduced cleaning necessities. For soldering applications on composite basis, we offer the grey finish K10101- or the black finish K10102. Both have excellent surface properties.

Our P12201 is perfectly suited for coating application with aluminum carrier. The smooth and robust surface reduces the remnants of sticking paint – also persistent paint residues can be removed far easier.  

Please ask for the appropriate finish for your application!


The increasing number of flexible boards in the Automotive, Computer, and Domestic Appliance industry require new approaches in the entire production process: 
Where previously rigid and semi flexible boards were directly transported through the process lines due to their lateral stability directly, flexible circuits with a thickness of 0.1 – 0.2 mm cannot be transported without a support medium.

The needs of a simple carrier system for the transport if flexible circuits are now being met:

Rubberfix is a sandwich component with an anodized aluminum base plate. The surface is covered with a completely polymerized, adhesive silicone modification which according to the surface quality covers the flexible circuits. The positions are normally found via tongued pins or a so-called basic plate with centering pins for individual circuits. 

In order to satisfy the different circuit surfaces, we offer shore hardnesses of 20, 40, and 70 shores. In principle this rule applies: the less the shore hardness, the better are the adhesion properties and the higher the shore hardness, the longer the service life of the Rubberfix coat by the reflow exposure. The basic thickness is about 1.9 mm, a thickness corresponding to PCB thicknesses that has no impact on your handling (transport, thermic).

Beneficial is the opportunity of machining which enables embedding SMD components on the Sidebottom side of the flexible board.

We would be glad to send you upon request a hand sample in all available shore hardnesses – please contact us!
