REACH and RoHS: Meeting Industry Compliance

For the safety of consumers during the service life and after disposal, material restrictions relating to electronics manufacturing help prevent the excessive buildup of environmental contaminants. While a necessary regulation, this legislation complicates an already intricate and challenging manufacturing process. Maintaining this compliance is important to prevent downstream issues like revisions or costly recalls, so…

Why is Copper Thieving Used in PCB Development?

I hate to admit it, but I admire jewel thieves as shown in movies. Now, don’t worry, I am not endorsing a life of crime or contemplating a career change. Rest assured that I fully understand that, in reality, there isn’t any such thing as a “gentleman” thief, and instead, it is all just robbery…


Controlled Impedance: Stackup Design

Trail construction, like roads or other similar pathing, has to contour to the features of the ground beneath it. These trails are usually built to minimize the impact of human activity, meaning the lay of the land takes precedence over ease of use (to a point). Trail designers avoid extended steep climbs, but sometimes it’s unavoidable. When there is the option, most trails will incorporate switchbacks, a longer but less taxing ascent than a direct route over the surface.

The characteristic impedance of transmission lines starts with the board stackup.

Blind and Buried Vias for Complex Stackups

As high-density interconnect boards continue to proliferate to meet modern devices’ dual high-performance and functionality requirements, board real estate is becoming more precious. Couple this development with a general tendency for consumer electronics toward portability, and designers must face the all-too-common problem of doing more with less. Historically, one of the more intractable board features…

PCB Mounting Hole Size for DFM

While most PCB drilling is for vias and through-hole components, some drilling does not encompass electrical connectivity. The board’s placement within the enclosure requires mechanical drilling for fasteners, and some large components, like connectors, may utilize support pins for additional vibration dampening. While simple features overall, PCB mounting hole sizes require a basic understanding of…

EMC Automotive Guidelines

The increasing prevalence of electronics in automobiles is welcome to consumers for many reasons: improved features increase safety measures or add new functionality that would otherwise be unachievable. There is a drawback with increasing electronic automation of the vehicle, as issues with signal transmission can undermine or override these safety features. For signal integrity, circuits…
