What Is In-Circuit Testing (ICT)? Importance for PCB Quality Manufacturing
Introduction Before talking about In-Circuit Testing for printed circuit boards. Do you ever wonder how electronic manufacturers use different types of methods to confirm that the printed circuit boards operate correctly prior to delivery at the customer level? Modern electronic devices are rapidly increasing in size and complexity. A minor PCB defect can create a […]
Glass Fiber Weave Effect on High-Speed Differential Pair
The glass fiber weave effect, also known as weave skew, is a critical signal integrity challenge in high-speed PCB design that occurs when differential pair traces experience uneven propagation delays due to dielectric constant variations between fiberglass strands and resin. As data rates climb into multi-gigabit ranges (PCIe Gen 5, USB4, 100G Ethernet), even picosecond-level […]
Copper Pour in PCB Design: Fill Empty Areas for Better Manufacturing
When electronic engineers create printed circuit boards (PCBs), they tend to leave many copper-free areas on the board. They are probably not aware of the technicalities of the PCB production process. A high percentage of the copper-free area on the board can have a negative impact on the product and leave it susceptible to early damage.
