Here is a case study that thick film resistor used in wearable device:

Customer Background

The customer, a leading manufacturer of wearable devices, faced challenges in achieving precise performance under varied environmental conditions, such as temperature fluctuations and exposure to moisture. The devices required reliable and consistent resistance to ensure accurate signal processing and power management. Traditional resistors in the market were either too large, causing space constraints in their compact designs, or lacked the durability needed for long-term performance in wearable electronics. The customer was also facing high manufacturing costs due to sourcing multiple components from different suppliers, making the procurement process complicated and time-consuming.

How We Solve It?

1. Customized Thick Film Resistors: We worked closely with the customer to develop high-performance thick film resistors tailored to their specific needs. These resistors were designed with a compact form factor, ensuring they could fit into the tight spaces of wearable devices while maintaining durability against environmental stressors.
2. Material Selection: By using specialized thick film materials, we ensured that the resistors maintained stable performance even in fluctuating temperatures and humid conditions, which are typical in wearable devices.
3. Cost Reduction and Simplified Sourcing: To streamline procurement, we became a one-stop supplier for all the electronic components, reducing the need for the customer to source from multiple vendors. This also allowed us to negotiate better pricing and ensure consistent supply, reducing lead times.
4. PCB Integration and Assembly: We provided a comprehensive solution that integrated these thick film resistors directly into custom PCBs, optimized for the wearable electronics' power management systems, and assembled the PCBs to meet the customer’s exact specifications.
