Case Studies<\/strong><\/td>\n<\/tr>\n
\n\n\n\n\n
Film on Glass (FOG) Machine – Flat Panel<\/td>\n<\/tr>\n
This machine bods film onto glass substrate. There are 3 XY tables and one 4m-long axis on this machine. For the XY table (two short stroke axes), the customer had been using ball-screw. The ball-screw mechanism can’t achieve high precision (high accuracy, high repeatability) because of backlash and mechanical vibration. Furthermore, ball screws need replacement every few months due to wear and tear. It is extra maintenance cost. So the customer wanted to switch to PBA Systems\u00a0DX B Ironless Linear Motor<\/strong>.<\/p>\n

The 4m-long axis uses 3 carriages. For this axis, the customer cannot use ball-screw, which can only use one carriage, whereas multiple carriages can run on one linear motor magnet track. Another reason why ball-screw is not suitable for the 4m-long axis is because the balls-screw shaft will deform under gravity for such a long axis. PBA Systems DX B Series Ironless Linear Motors easily overcome the above problems.<\/p>\n\n\n\n\n\n\n

High Accuracy Laser Scriber Machine for Wafer Cutting<\/td>\n<\/tr>\n
This machine uses laser beam to cut metal coated 6-inch wafer. The machine has one XY stage and one Z axis. Z axis uses rotary servo motor to focus the lens. The customer requires high accuracy and low velocity ripple, and, vibration-free motion on this XY stage. The customer decided to use PBA Systems\u00a0DX B Series Ironless Linear Motor<\/strong>\u00a0for the X and Y axis as a cost effective solution to meet their requirements. Ball-screw can not achieve high accuracy motion because of backlash and mechanical vibration. PBA Systems DX B ironless linear motor was selected for its high accuracy, low speed ripple and competitive price.<\/p>\n\n\n\n\n\n\n

High Frequency Camera Focus System<\/td>\n<\/tr>\n
The customers’ machine uses camera to focus on very tiny objects. The motion of this camera unit is point-to-point, high frequency (high acceleration and low dwell time) and short stroke. Other requirements on the actuator are small size and low settling time. The customer had been using ball-screw. But the ball-screw mechanism can’t achieve high frequency and low settling time because of backlash, mechanical vibration, and high friction. Furthermore, ball-screw requires replacement every few months due to wear and tear. It is extra maintenance cost. Customer decided to use PBA Systems\u00a0CVCA Series Voice Coil Actuators<\/strong>\u00a0to overcome the ball-screw drawbacks. CVCA50-30 is used for this application. It is more cost-effective compared to a linear motor solution.<\/p>\n\n\n\n\n\n\n

Benchtop Dip-Coating Machine<\/td>\n<\/tr>\n
The existing wafer dip coating machine uses a ballscrew actuator for the Z-Axis. Due to the friction of the ball screw, there are velocity ripples that creates periodic lines on the coating. PBA Systems created a full benchtop single axis machine for this purpose using the\u00a0DX20B-C3S<\/strong>\u00a0Ironless Linear Motor<\/strong>\u00a0which has far less friction. It uses a servodrive with a regulated 48V DC power supply to ensure low noise levels in the DC bus Voltage.<\/p>\n

PBA Systems created a cost effective full solution that includes the software, motion control card, servodrive and full mechanical assembly for the particular silicon wafer to be coated. Using direct drive technology, PBA Systems offered a high performance alternative to off-the-shelf lab machine. Not only will the direct drive motors increase performance of the system, the source code provided enables the customer to expand the functionality of the machine for research or production.<\/p>\n\n\n\n\n\n\n
