Understanding PCB Creepage and Clearance Requirements

Every engineer who has designed a mains-powered or high-voltage board has felt it: the design passes every functional test, but the spacing between a live trace and a nearby low-voltage signal suddenly looks dangerously small. Creepage and clearance are two of the most misunderstood requirements in PCB design. Get them wrong and the board fails … Read more

Designing Test Fixtures for Small Batch PCB Prototypes

When a prototype board comes off the SMT assembly line, the next question is always the same: does it actually work? Engineers at semiconductor labs, medical device startups, and industrial control firms know that without a repeatable test setup, every verification cycle becomes a hand-built, one-off exercise. Test fixtures for small batch PCB production don’t … Read more

Signal Integrity Analysis for High-Speed Digital PCB Design

High-speed digital signals don’t care about your layout assumptions. When rise times shrink below a nanosecond, a PCB trace stops behaving like a simple conductor and starts acting like a transmission line — introducing reflections, crosstalk, and timing errors that can cripple a product before it ever reaches your customer. Engineers at semiconductor labs, medical … Read more

PCB Trace Width and Current Capacity: A Designer’s Reference

When your PCB prototype fails to power a high-current component or overheats traces during testing, the root cause is often a trace width that was never calculated for the actual load. Engineers developing power modules, industrial motor controllers, and semiconductor test fixtures face the same recurring frustration: a design that looks perfect in the schematic … Read more

Mixed Technology Assembly: Combining SMT and Through-Hole

When your PCB design includes a mix of fine-pitch SMT components and rugged through-hole parts, managing two entirely different assembly processes in a single build can quickly become a logistics nightmare. Engineers developing industrial controllers, power supply modules, and mixed-signal medical devices face this reality every day — reflow profiles optimized for SMT solder joints … Read more
