Circuit Board Guidelines: Copper Weight vs. Lines and Spacing

Written by Angie Brown
Posted on November 24, 2020 at 8:56 AM

When I think of the song, “Through the Years” by Kenny Rogers from 1981 (played at my high school graduation in 1982), I wouldn’t have imagined I would still be in the printed circuit board (PCB) industry. Yes, 1982! Wow. There are several nostalgic “things” about the time spent in the industry that still remind me of my hometown, family, friends, the U.S., my first real job doing something I had never heard of, hoping to make ends meet.

Design Considerations When Using Batteries in Portable Devices

Written by Anton Beck
Posted on November 10, 2020 at 8:47 AM

Portable devices are everywhere. When thinking about the top portable devices that we use daily, smartphones, tablets, and laptops will dominate the list. Yet, there are numerous applications that rely on portable devices. Manufacturers of medical devices, military devices and even kid's toys rely on holder and mounting designs to secure batteries in portable devices. How the batteries are secured plays an important factor. These applications can experience a range of extremes such as shocks, vibrations, drops, and temperature fluctuations.

When sourcing custom cable assemblies, customers seek the highest quality design and manufacturing capabilities at the lowest costs. Due to these factors, many customers source their custom cable assembly builds from offshore manufacturers. These cable assemblies may consist of ordinary data cables, low voltage wire harnesses, high-resolution video cables, or something completely custom.

The Pros and Cons of Building a Prototype HMI for Electronic Devices

Written by Jason Sayde
Posted on October 20, 2020 at 9:13 AM

It is not often we build an electronic device without any sort of prototyping, but it can happen given the nature of the project and the deadlines being met. If a customer needs a Human-Machine Interface (HMI) to hit the floor in 2 months, the time to develop and build a prototype is strained as both the customer and design engineers will want to test it and provide feedback.

Differences in Controlled Impedance Between a Rigid PCB and Flexible PCB

Written by Paul Tome
Posted on October 6, 2020 at 9:32 AM

As with many of today’s high-speed rigid circuit board designs, flex and rigid-flex PCB designs also require controlled impedance signals. The impedance vales are the same, typically ranging from 50 ohm single ended up to 120 ohm differential pairs. However, there are differences in how the impedance values are achieved due to the mechanical bend requirements that a flex or rigid-flex circuit board must meet that a rigid PCB does not.
