Screen Printing for Circuit Boards

Problem: To print a circuit board accurately every time, a squeegee has to press the ink through the screen evenly and maintaining the proper force. This requires pressure to be applied by a reactive, intelligent actuator solution to ensure a perfect finish on the end product.

Solution: Two SMAC LAL-90 actuators, with reactive software to establish and maintain the correct position and force for the squeegee. As the squeegee is moved over the screen, the actuators track each other to maintain their position. The force applied by each actuator is dynamically adjusted.

Force can be controlled to +/- 25g, position can be maintained to +/- 5 encoder counts.
