Printed electronics - longstanding knowledge of print technology coupled with the latest developments in materials science

Printed electronics refers to electronic components, modules and applications that are completely or partially made using a printing process. Electronic function materials, in liquid or paste form, are printed. Using this process, Hoffmann + Krippner has produced membrane potentiometers, defined resistors and surface keypads for more than 13 years. Resistance values with deviations of +/-30% were possible in the past. Findings in materials science and organic chemistry now allow values of +/- 10%. In terms of linearity, H+K is reaching values of less than 1%. To meet the requirements, Hoffmann + Krippner has redefined its production processes. Ranging from incoming goods inspections for membrane foils and colors, implementation of new measuring equipment and methods during production to optimize virtually all processes within the company, from the design and development departments through production to final assembly and inspection of outgoing goods. Thus, quality requirements can also be met as a supplier for the automotive industry.
