Application Example Dam and Fill

Protection of Highly Complex Areas

Dam and Fill applications protect highly complex areas particularly reliably. The first step is the application of a highly viscous barrier – the dam. In the next step the area is filled with a filling material. The dosed area is sealed with flowable material and therefore protected.


Clean Dosing with Dam & Fill

Fritsch GmbH from Kastl/Utzenhofen knows all about dosing technology. However, the filling of a circuit carrier with silicon proved to be a challenge.  There was only one solution for a clean result: The manufacturer of SMT technology used the tried and tested eco-PEN from preeflow. High repeatability, precise processing and user-friendly handling: characteristics that distinguish preeflow products. Fritsch was soon impressed.

And it has not disappointed. The preeflow eco-PEN provides reliable volume dosing of a wide variety of materials. It is capable of compensating for external factors such as the ambient temperature.

An all-round talent for clean dosing results.
