Welcome to the AP&S Demo Center

AP&S Demo Center

Are you looking for a perfect wet process solution meeting your specific requirements? Come to our in-house application laboratory at the AP&S headquarters in Donaueschingen, Germany and you will find it.

An investment in a wet process application is a significant decision, at which many important aspects and complex contexts have to be taken into account. AP&S supports efficiently your decision making process by providing a variety of tool demonstrations. By visiting our demo center you will receive all required information for a well-founded buying decision:

Process experience 

In the AP&S demo center you can test the wet process application, which you are interested in. Our high-qualified process engineering team will explain you all details of the process tool and will answer all your questions. You will receive a comprehensive test report containing complete parameters of the process set-up, a recommendation for process recipe due to test results and further important system configuration details.

Quality check

After the demonstration the quality of the wet process results can be inspected with a microscope and a CCD-Camera.

Time and cost savings 

Until the start of the production we offer you an in-house process evaluation including a definition of process parameters, a calculation of the throughput as well as the chemical consumption.

High process efficiency and optimal outcome 

Prior to the tool delivery we invite your staff to our demo center for in-house trainings. Thus, directly after the tool installation they will be able to start their work and achieve optimal results with the new tool.  


By visiting the AP&S demo center you will get to know our wet process tools and their performance. Furthermore you will see the company headquarters including the production hall; find out how we use to work and last but not least you will get to know the people behind AP&S.

We look forward to your visit! Please fill-in the contact form and our process engineering team will contact you for making an appointment.
