After the critical circuits, we like to examine the printed-circuit board (PCB) stackup. Like the schematic, board stackup decisions are often made prior to routing and placement, so this is a good ...

Most every device and electronic piece of equipment is outfitted with a printed circuit board (PCB), including smartphones, TVs, appliances, and more. You know the composite. The boards are laminated ...

The basic metallurgy of solder. How to make a solder joint. How to repair a circuit board. The vintageTEK museum is a geek’s paradise to tour if visiting the Portland, Oregon area. The museum has ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

For reliability, designers must create flex circuits that are neither too thick nor bend too much. • Every flex circuit has a neutral-bend axis. • Smaller circuit thickness reduces the risk of damage ...

Last, but not least, we like to look at the I/O (Input/Output) circuits during EMI circuit board reviews. As a port of entry for external currents, I/O circuits are particularly vulnerable to threats ...
