Printed Circuits by 100% Additive Processing

flexible rigid printed circuits conductive inks PET PEN PI GSIManufacturing utilizing 100% additive printing processes offers a low cost means to produce many unique circuit designs. GSI services numerous customers with our conductive printing capabilities, and with our years of experience printing conductive, resistive, and dielectric materials on a variety of flexible and rigid substrates. Most customer designs are unique and require GSI’s expertise in matching ink characteristics with print processes and end product performance attributes. GSI has scaled many challenging circuit designs requiring:

  • Produce sheet samples and seamlessly scale to roll processing
  • Delivery of parts in roll or sheeted formats
  • Double sided circuits with and without printed thru-holes
  • Roll to roll capabilities allow processing thin gauge substrates
  • Very broad printed substrate selection: polyester (PET, PEN), polycarbonate (PC), paper, polyimide (PI), polyetherimide (PEI), and most other films
  • Adding printed features to copper flex or rigid circuit boards

Printed Circuits for Wearable Electronics

GSI Technologies is at the forefront of manufacturing and leading development efforts on wearable products where printing solves technical issues. GSI utilizes ink sets including Ag, Ag/AgCl, carbon, and dielectric inks from multiple vendors. These inks sets are specially designed for use with flexible substrates. The flexible substrates have included a variety of TPU (thermoplastic polyurethane) based materials. Along with materials knowledge, GSI is able to use its manufacturing capabilities such as sheet or roll based through hole printing and high precision laser converting to enable new product designs. With our downstream converting partners, wearable parts can also have adhesive applied, be final packaged, and sterilized.
