Flex PCB Stiffeners: Materials, Thickness and Design Guidelines
Choose reinforcement around the job it must do: support a component area, build a connector tail to its finished thickness, or strengthen an attachment point.
PCB Fiducial Marks: Size, Placement and Design Guidelines
Understand global, local and panel fiducials, distinguish copper diameter from mask opening, and check your design before PCB assembly.
Rigid-Flex PCB Bend Radius Guide
Learn how to estimate rigid-flex PCB bend radius, choose flex thickness and copper, plan bend zones, and validate static or dynamic designs.
High-Frequency PCB Material Selection Guide
Select high-frequency PCB materials by comparing dielectric data, copper, stackup, environmental stability and manufacturing options, then validate the complete RF path.
HDI PCB Design Guide
Plan HDI PCB stackups, microvia connections and BGA escape routing, then check manufacturing rules, assembly and reliability before fabrication.
6 Layer vs 8 Layer PCB: Which Is Better for Signal Integrity?
Choosing between a 6-layer and an 8-layer PCB stackup is rarely about the dollar figure on the fabrication quote. It’s about whether your high-speed signals have a reliable return path [...]
PCB Grounding Design and Layout Best Practices
1. Ground Wire All parts that are connected to ground are linked together through one common trace. This is common in old PCB designs and in simple PCB designs. 2. [...]
