ABSTRACT:
The drying characeteristics of a printing paste comprising a vehicle containing a binder and a low boiling point solvent are improved by substituting a high boiling point solvent for a portion of the low boiling point solvent without substantially adversely affecting the viscosity and flow properties of the paste. The printing paste is advantageously employed in silk screen printing in multiple passes where printed layers must have a uniform degree of wetness. The printing paste and vehicle are especially useful in the manufacture of microelectronic packages.
