摘要： A method of digitally printing a solder mask. The method includes providing a solder mask ink composition including: 1) a resin and 2) a solvent in an amount of at least 20% by weight relative to the total weight of the solder mask ink composition. The composition has a viscosity that is less than 1000 cps at a shear rate of 10 s−1 and a temperature of 25° C. An aerosol stream is generated from the solder mask ink composition with a pneumatic atomizer using an atomization gas. The aerosol stream is directed through a nozzle and focused using a sheath gas onto a substrate while changing the position of the nozzle with respect to the substrate to selectively deposit a solder mask pattern. The solder mask pattern is cured.

摘要： A solder mask ink for aerosol jet printing includes a metal oxide and a propylene glycol-based solvent; the solder mask ink has a viscosity from about 50 cps to about 1,000 cps at shear rate of 10 1/s at 25° C., and a shear thinning index from about 1.0 to about 2.0.
