How to design PCB electronics for reliable brownout recovery

How to design PCB electronics for reliable brownout recovery

Designing PCB electronics for reliable brownout recovery means controlling what happens before, during and after the supply leaves its valid operating range. A board that restarts after a clean power cycle can still fail during a shallow dip, a slow voltage collapse...
How to select power semiconductor devices for reliable motor drives

How to select power semiconductor devices for reliable motor drives

Selecting power semiconductor devices for a motor drive is a system-level decision, not a search for the lowest on-resistance or highest current rating. The right switch must survive the DC-link envelope, repeated overloads, switching transients and fault conditions...
ESD protection for a printed circuit board in an industrial computer

ESD protection for a printed circuit board in an industrial computer

Protecting a computer printed circuit board against electrostatic discharge (ESD) takes more than adding a transient voltage suppressor beside each connector. In an industrial computer, discharge current can enter through an operator interface, cable shield, enclosure...
How to assess validation plans from an electronics design company

How to assess validation plans from an electronics design company

A validation plan from an electronics design company should do more than list tests. It should explain which product claims will be demonstrated, under which conditions, on which hardware and firmware versions, and what evidence will support a release decision. For a...
How to design a printed PCB board for automated testing

How to design a printed PCB board for automated testing

A printed PCB board designed for automated testing needs more than a row of accessible test pads. It needs a defined test strategy, controlled power-up, measurable acceptance criteria and firmware that allows the production station to exercise the hardware safely....
How electrical engineering services address component obsolescence

How electrical engineering services address component obsolescence

A component end-of-life notice can threaten production, field support and the evidence behind a qualified product. Effective electrical engineering services address that threat as a system-level change, not simply a purchasing problem. The objective is to maintain...
