How Does Trace Width Calculation Impact PCB Design?

Yes, It may Ruin Your PCB In-house Party.

Traces within the PCB are used to connect various components to various connectors. These traces can be identified as continuous paths of copper that exist on the surface of a circuit board. The trace width becomes crucial as it directly impacts on the working of the PCB. Additionally, increasing electricity flowing through PCB traces produces an immense amount of heat. Monitoring trace widths also helps minimize the heat build-up that typically occurs on boards. The conductor width also determines the resistance of the traces that directly affect the electricity flow.

Comparing the Manufacturability of PCB Laminates

This presentation will discuss how to properly select PCB laminates or materials. Before selecting begins, there are many factors to consider. Make sure material characteristics fit your specific board requirements and end application. Today, we will focus on the dielectric properties, cost, and manufacturability of materials suitable for high-speed PCB designs.

Ultra-low Impedance Testing Using the 2-Port Shunt-Through Measurement Technique

Measuring ultra-low impedances (20 micro-ohm) is a challenge for any power distribution network (PDN) design engineer. The 2-port shunt-through measurement is the standard method for measuring milliohm impedances up to very high frequencies (GHz). Unfortunately, this measurement includes an undesirable ground loop related to the instrument grounds and test setup cabling. The ground loop introduces significant errors if proper care is not taken. This application note shows how to measure as low as 20 μΩ using the Picotest J2102A as a ground loop breaker.
