material notes
DuPont™ QM44 is a crystallizable non-conductive dielectric that can be screenprinted. It is formulated to be an integral part of the DuPont™ QM44 system and it is versatile for high reliability and low cost multiple chip modules. It can be applied using a 230SS mesh screen to achieve a fired on thickness of 30µm. The recommended process is to allow the prints to dry at room temperature for 10-15 minutes followed by drying at 150°C for 10-15 minutes then fired for 30 minutes with a soak temperature of 850°C for ten minutes. The thinner for this ink is DuPont 4553. FOR REFERENCE ONLYKey Properties
