What is Skew in a Differential Signal?

Are your high-speed differential signals failing, even though the design looks correct? You’ve followed the rules, but intermittent errors and EMI failures are causing major headaches and project delays.

Is Panelization Needed for Small PCBs?

Struggling with manufacturing small circuit boards? The handling costs and manual processes can kill your project’s budget and timeline. But worse, a poorly planned panel can introduce defects that haunt you in production. Proper panelization is the key to efficient, reliable, and cost-effective automated assembly.

What are the Negative Effects of ESL in a Circuit?

Struggling with high-frequency noise, transient response failures, or unexplained system instability? You’ve followed the app notes, but your design is still marginal. The root cause often lies beyond basic component selection and deep within the parasitic effects that govern high-performance circuits.

What are ESR and ESL in capacitors?

Is your high-speed interface failing eye-diagram tests, or is your power supply control loop showing strange oscillations? Before you blame the silicon, the answer might lie in the second-order effects of the most common component on your board: the capacitor.

Is a Watchdog Timer Needed for All MCUs?

Struggling with a product that mysteriously freezes in the field? A simple software bug can lock up your microcontroller, making your device unresponsive and frustrating customers. A watchdog timer is the essential hardware fail-safe that prevents this from happening.

What Factors Affect PCB Trace Impedance?

Struggling with intermittent signal integrity failures in your high-speed designs? Are you seeing closed eye diagrams or failing compliance tests? The root cause is often a breakdown in a fundamental principle: the control of PCB trace impedance.
