Title: Helmut Hadwiger: Innovator in Printed Circuit Board Technology
Introduction
Helmut Hadwiger is a notable inventor based in Munich, Germany. He has made significant contributions to the field of printed circuit board technology, holding a total of 3 patents. His innovative methods have advanced the manufacturing processes and applications of printed circuit boards.
Latest Patents
Hadwiger's latest patents include a method for applying a solder resist layer to a printed circuit board. This method involves the successive application of a solder resist and a positively-acting photoresist onto the board's surface. The photoresist is selectively exposed and developed in the regions of plated-through holes and solder pads, preferably using laser beams. The solder resist is then stripped in the areas not protected by the photoresist, making this method particularly suitable for three-dimensional printed circuit boards.
Another significant patent is for the manufacturing of metal core printed circuit boards. This method allows for the creation of two or three-dimensional metal core boards of various forms. The manufacturing process can utilize injection molding, injection/compression methods, or pressing methods. High-heat resistant thermoplastics and thermoset plastics are preferred materials, with a metal core selected for its thermal conductivity. The process includes laminating the metal plate with a plastic foil and thermoforming the plastic over the laminated core.
