Battery End Of Life Vs. State Of Charge

Written by Anton Beck
Posted on August 16, 2019 at 9:03 AM

Within the context of a discussion about batteries, defining the term "state of charge" is simple. It's a term that essentially refers to how "full" your battery is, at least in terms of its remaining energy. Compared to how much energy a battery can store at 100%, your current state of charge shows you how much is remaining, thus allowing you to predict when a recharge may be in order.

Lithium Batteries: Cylindrical Versus Prismatic

Written by Anton Beck
Posted on August 6, 2019 at 8:27 AM

By and large, lithium batteries bring a wide range of different benefits to the table that are difficult - if not impossible - to replicate in any other way. Also commonly referred to as lithium-metal batteries (due to the fact that they use lithium as an anode), they're typically capable of offering a very high-charge density (read: longer lifespan) than other alternatives that are on the market today.

DFM For Your Quick-Turn PCB Order

Written by Al Wright
Posted on July 31, 2019 at 9:12 AM

Design for Manufacturing (DFM) is critical to the success of your PCB order. Features that make your circuit board difficult to build add cost to your product and can increase the scrap rate. If you have designed a PCB that is more complex than usual, it is useful to submit files to your fabricator for review before placing your order so you will have some time to address any issues that might delay production.

Using Wire-To-Board PCB-Mounted Connectors In Your Cable Assembly

Written by Steven J Goodman
Posted on July 23, 2019 at 8:51 AM

In simple terms, cable assemblies are comprised of two primary elements: the conductor and the connector. Rightfully so, the conductor’s sole purpose is to pass current at a given voltage, while the connectors job is to affix the cable assembly securely to a mating interconnect.

Maybe you have heard of technical writing before, or maybe this is your first-time hearing about it. The chances are good, however, that you have seen or experienced technical writing already in your life. It is an established practice within the industrialized world, but what is it?

A PCB Trick for Vias and Impedance Traces

Written by Al Wright
Posted on July 11, 2019 at 10:51 AM

Ordinarily you may not want your PCB (printed circuit board) manufacturer to adjust your data files, but there are occasions when that may be the easiest way to achieve a particular result. For instance, you may need to have some, but not all, vias of a particular size plugged so that the assembly solder will not wick through to the other side of the board. Or perhaps a few trace pairs need to run at a specified impedance, while the impedance for all the other traces of the same width is non-critical.

Balancing Layers in Your PCB Layout

Written by Al Wright
Posted on July 2, 2019 at 9:22 AM

The design of a multi-layer PCB (printed circuit boards) can be very complicated. The fact that a design even needs to use more than two layers implies that the required number of circuits will not fit onto just a top and a bottom surface. Even in cases where the circuitry does fit onto two external layers with no problem, the PCB designer may decide to add power and ground planes internally in order to correct a performance shortcoming.

How to Specify Your PCB Controlled Impedance Requirements

Written by Al Wright
Posted on June 26, 2019 at 11:14 AM

Owing to the prevalence of complex processors, USB devices, and antennas printed directly onto the board surface, more and more PCB designs now require impedance control and testing than ever before. In response to the increased demand, circuit board manufacturers have invested in sophisticated modeling software and testing units, so they are equipped to meet the requirements.
