Nitrogen Fireable Pastes

High reliablity and structuring flexibility is realized by Thick Print Copper (TPC) technology

Thick Printed Copper

TPC pastes are applied to AlN or Al2O3 substrates by screen print process suitable for layers of thickness up to 300 µm.

As a hybrid TPC can provide thick layers for power like MOSFET and IGBT while signal tracks and logical devices thinner layers are applied on the same ceramic - this combination of power and logic components on one circuit allows for minimum inductance and optimum space utilization.

Heraeus has developed a thick printing Cu conductor paste system for power electronic applications where excellent print quality, thermal conductivity and soldering properties are required. Heraeus' thick print copper system has been developed to be applied on alumina and some aluminum nitride substrates.
