Overview
This laser trimming probe card enables precise adjustment of the resistance values of chip resistors, hybrid ICs, and other components.
*Only blade pins are supported for functional trimming of hybrid ICs.
Features
• High-density probe mounting for fine pads
• Designed to withstand repeated trimming processes
• Customizable to match product shape, components, and terminal layout
• Repair and rebuild services available from a single pin
Applications
• Laser trimming adjustment of chip resistors
• Laser trimming adjustment of hybrid ICs
Polyimide coating technology (mechanism and effects)
In laser processing, dust and debris can adhere directly to the probe tip, causing fluctuations in contact resistance and, in turn, measurement errors and drift.
This technology coats the probe tip with a polyimide insulating film 5–10 μm thick. By physically blocking dust, the film stabilizes the contact state.
The following effects can be expected:
• Reduced fluctuations in contact resistance
• Stabilized measurement accuracy
• Drift suppression
• Reduced maintenance load
This technology has a proven track record in mass production lines.
