Application Engineering

Application Engineering

We have the skills and knowledge to design, build and test virtually any product or assemby for connectivity solutions. However, what makes Teesing Engineering unique, is combining existing products with custom solutions to create the assembly in the most efficient and cost effective manner. We are not limited to a certain brand or product range. Before starting production, Teesing’s engineers develop the assemblies in 3D design in CAD to ensure the right specifications.

Cleanroom Solutions

Cleanroom Solutions

Together with its partners, Teesing can handle anything from a few samples for prototypes to complete assemblies for volume production. Cleanliness is tested using UV and Laser technics. Extreme clean dry air (XCDA) with sub ppb levels of contaminants is used and Teesing has bake-out capabilities. This ensures minimal particle counts and reduces TOC levels, in order to deliver sub-systems or components ready for producing nanotechnologies. The UHP products c

After cleaning an assembly or product for our clients in the semiconductor and mechatronics industry, we can store this in a number of leanlifts that have been conditioned and are over pressured. This system ensures that cross contamination and movement of particles are kept to a minimum. The products are stored in a safe and clean manner.

Cooling applications

Cooling applications

We designed a Liquid Filter Unit that filters coolant before it enters the heat exchangers in radar equipment. We used an industrial commercially available filter and built a frame work around it with required valves and connections to make it suitable for the demanding environment on navy vessels. The coolant liquid is filtered down to 1 μm contamination.
Commercially available industrial components are not necessarily suitable for use in demanding marine applications, while the price and specification are interesting. By creating a frame around it, the filter can be used in this environment, protecting it from shocks and by even facilitating a redundancy function for some double filter versions.
The end result is a plug-and-play product, assembled and pressure tested. By combining the industrial filter with a frame and connectors, a competitively priced product is created, suitable for the job.
