Perfect Thermal Profile for Wearable/IoT PCB

Creating a perfect thermal profile for a wearable/IoT PCB undergoing the reflow process is a challenge. That challenge is based on the fact wearable flex PCBs are smaller, and they don’t have sufficient thermal mass compared to conventional rigid PCBs. Also, they have different thicknesses and when it comes to flex, even different thicknesses, where […]

Fixtures and Special Tooling for Wearable and IoT PCBs

Fixtures and special tooling are used to further assure surface mount (SM pad) stability and preciseness on a wearable or Internet of Things (IoT) PCB during the pick and place operation. The figure below shows a comparison between fixtures for conventional and flexible PCBs. These assembly steps are especially important since some wearable or IoT […]
