High Tg PCB Fabrication and RFQ Specification Guide
High Tg materials improve thermal-mechanical reliability, but they also change the fabrication window. Drilling, desmear, lamination, plated hole reliability, moisture […]
High Tg PCB Material Selection Guide
Standard FR4 has a glass transition temperature (Tg) of 130–140°C, measured by TMA. Below that threshold, the resin behaves like
When Standard FR4 Becomes a Reliability Risk in Lead-Free Reflow
Lead-free soldering has been the industry standard for nearly two decades. Since the RoHS directive reshaped electronics manufacturing, SAC305 has
What Is FR4 PCB? Material Properties Explained
FR4 is the material most printed circuit boards are made of, yet it is also the material most often left
