Customised Thick Film SMD Resistors

TSEC designs and manufactures custom thick film surface mount resistors in low to medium volume.

The major resistor manufacturers provide a vast range of surface mount (SMD) resistors. Where a standard device will not achieve the required specification or there is an obsolescence issue TSEC delivers application specific solutions.

Thick film SMD resistor devices offer several advantages over MELF-type resistors including:

• High packaging density
• Higher speed mounting with pick-and-place equipment
• Reduced cost

However, surface-mount resistor devices are generally not suitable for large, high-power, or high-voltage parts.

TSEC works with system designers to create custom SMD resistors to match the demanding requirements of specific applications.

Flip Chip Resistors

TSEC specialises in the design and manufacture of customised flip chip surface mount resistors. Compared with standard surface mount resistor devices, flip chip configuration offers several advantages, including improved contamination resistance and reduced noise characteristics.

Flip chip technology eliminates the need for wraparound lead frames, allowing higher component density. This construction method also relieves strain when system boards are subjected to thermal or mechanical stress.

Where product obsolescence is an issue, TSEC designs and manufactures custom form, fit, and function replacements for obsolete SMD resistors using flip chip technology.
