Chip Mounting

Problem

Most production line chip mounting processes have restrictions because of the speed of their pick and place system. Using traditional pneumatic actuators results in a short life-span, a high failure rate and the system can therefore suffer from a chip mounting imagelack of precision in force and placement.

Solution

The SMAC LAL-90 actuator operates at 10 parts per second, with the up or down stroke, stop to stop, in 30 milliseconds. The actuator is capable of high force and high acceleration which leads to high-speed and high-accuracy in a production environment. To place a chip, the actuator rod moves down to compress a spring-loaded nozzle, placing the chip accurately in place and in force. The solution operates with high g-force, using a fast setting tome and with a 20 micron overshoot/undershoot. There are separately programmable PID servo parameters for down stroke and for up stroke.

SMAC’s patented SoftLand system ensures that delicate parts are placed accurately and therefore cause zero part damage.
