Screen Printing on Low Temperature Cofired Ceramics
Résumé
In order to improve screen printing quality of gold paste onto LTCC tape, an experimental design has been performed. The tested parameters, related to the EKRA M2H screen printer, are squeegee pressure, squeegee speed and snap off distance. Line widths and gaps sizes of 75, 100 and 150 µm were printed and optically measured in green state. The best setting, 30-45 bar squeegee pressure, 25 mm/s print speed and 0.7 mm snap off distance, results in an oversize of line widths and an undersize of gaps in the order of 15-19 µm.
