This article describes the new possibility for higher quality deposition of thick film and similar materials with thixotropic character. Additional ultrasonic energy allows the local influence of the viscosity inside the dispensing system. Thixotropic character of materials in combination with selective effects of ultrasonic energy has a positive effect on the flow control and homogeneity inside the dispensing needle. The first results achieved by measurement of the system with ultrasonic energy describe the behavior of the dosing process. Measuring included the monitoring of the usual parameters of deposited layers as the width and thickness of lines, the possibility of creating radius and patterns with various shape. Additional energy does not change the basic methods of printed layers design, but allows move the resolution limits and ensure an optimal quality of leveling process already during the deposition. Optimization of dispensing head is tested in terms of benefits currently in possibility effect increases of resolution for printing technology of thick film materials for the production of hybrid integrated circuits. The optical comparison is selected as the evaluation for quality and dimensions of printed layers implemented in different trajectories of dispensing head movement. |
