Latest Patents

One of Poelzing's latest patents focuses on the molding of thermoset materials. Various methods have been proposed for measuring the viscosity of thermosetting polymers, but many of these methods are generally inaccurate. Poelzing proposes a test that avoids the inaccuracies of previous techniques. In this test, heated thermosetting resin is forced at a known flow rate through a runner and a capillary tube at the end of the runner. By measuring the pressure differential across the capillary, a meaningful measure of viscosity is obtained.

Another significant patent by Poelzing is a method for encapsulating integrated circuits. In molding integrated circuit packages, voids are often found in the molded plastic due to air entrapped in the charging container. Poelzing discovered that entrapped air can be avoided if a portion of the preheated charge material has a higher viscosity than the remainder. This is conveniently achieved by preheating the preforms in a temperature gradient and charging the hottest preforms last into the container. The pressure causes the material at the top of the chamber to flow first, thereby expelling unwanted air through the runners ahead of the plastic flow. An effective implementation results from tilting the RF electrode in the preheating apparatus.
