Abstract
A device for testing small electronic components includes a test plate for moving a plurality of spaced electronic components to a test station. A roller is designed to press on the test plate and electronic component exerting a first force between 10-20 grams when the test plate and electronic component are moving and exerting a second force of about 50 grams when the test plate is stopped and the electronic component is aligned in the test station. The forces exerted on the test plate and electronic component are controlled by a force-application actuator, such as fluid operated actuator, for example a pneumatic actuator or a solenoid.
