Thick Film Resistor Network Manufacturer
We design and manufacture custom thick film resistor network components for specialist applications. We work with customers to design and manufacture a technical solution in space-saving single-in-line packages.
With an engineering heritage extending back over 30 years, we focus on specific customer requirements, delivering reliable resistor network products that continue to perform to specification in demanding applications.
Custom Thick Film Resistor Networks
High-volume resistor network applications include pull-up/pull-down, level translation, line termination and pulse squaring.
TSEC deliver custom resistor network products for more specialised applications, including:
- Precision amplifier applications.
- Thick film resistor bridges.
- TCR matching applications.
- Gyroscope sensing resistors.
We can manufacture a wide range of application-specific resistor network configurations, with resistance ranges from 1 Ohm to 100MOhms in block resistor designs to over 1,000MOhms in high-voltage meander designs. We deliver resistor networks with or without resistor matching.
Low To Medium Volume Manufacture
High-volume manufacturing with standardised and highly automated processes excels at delivering consistent quality at low cost.
In contrast, TSEC tailors materials and processes to meet stringent performance specifications. The custom resistor network manufacturing process is optimised to enable multiple sample runs, prototype deliveries for approval and manufacture in the low to medium volumes usually required for specialised applications.
Resistor Network Application Information
To develop an application-specific thick film resistor network device, TSEC requires the following information:
* Number of resistors and values.
* Tolerance.
* Dimensional constraints.
* Power / current rating.
* Operating frequency.
* Operating and maximum voltage.
* Pulse withstand requirements.
* Temperature Coefficient.
* Termination (SMD/T.Hole).
* Number of terminals.
* Length of pin.
* Required date and quantity.
Armed with this information, TSEC will design and manufacture custom resistor networks for your specific application.
Resistor Network vs Discrete Devices
A resistor network offers several advantages over discrete resistors, including:
* Saving space on board.
* Reduced resistor drift and significantly improved temperature tracking.
* Reduced system board interconnect and higher reliability.
* Value matching.
Space Saving
A resistor network has only one packaging overhead rather than two (or more) with discrete devices. This eliminates issues with closely packed discrete devices on a system board.
The system board layout is simplified, improving reliability and reducing both the design time and system board cost. Inventory and qualification costs are also reduced.
Resistor Network Thermal Performance
Thermal effects can cause a variation in resistance between two discrete resistors. The proximity of external heat sources may impact the resistance of one discrete resistor relative to another. Manufacturing variables in discrete resistors can result in differences in self-heating effects.
A resistor network device with resistors in close proximity on the same substrate, with the same manufacturing process, helps resolve these issues. TCR matching issues can be reduced or eliminated.
Reduced Interconnect
A resistor network replaces the system board interconnect with an interconnect on a fully tested resistor component. This approach can improve the overall reliability of the system.
Resistor Value Matching
Many precision instrumentation and measurement applications require resistor pairs, closely matched in value. Resistor networks deliver excellent resistor-to-resistor matching.
Example Application Specific Thick Film Resistor Network Product
