Method of aerosol printing a solder mask ink composition |
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. |

1. A method of digitally printing a solder mask, the method comprising:
providing a solder mask ink composition comprising: 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, wherein 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.; generating an aerosol stream from the solder mask ink composition with a pneumatic atomizer using an atomization gas; directing the aerosol stream through a nozzle and focusing the aerosol stream 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; and curing the solder mask pattern. |
