Flex Circuit Design Challenges: Electrical vs. Mechanical

Written by Paul Tome
Posted on February 18, 2020 at 9:21 AM

Flex and rigid-flex circuit boards are a combination of both electrical and mechanical requirements that allow for solutions to many tight packaging requirements. However, this combination is also the potential source of design challenges as some electrical requirements can have a negative impact on the mechanical bend capabilities of flex circuits. If not, correctly addressed the reliability of the finished design may be compromised.

Rechargeable batteries are everywhere. From the laptops we type on to the portable medical equipment used to perform examinations or provide health record information, rechargeable batteries help to provide products and services to make our lives better. However, not many people know about what goes into recharging a battery in the correct manner, the right charger for certain battery chemistries, and where a battery management system (BMS) fits into the process.

EMI and RF Shielding Options for Flexible Circuits

Written by Paul Tome
Posted on February 4, 2020 at 9:03 AM

Flexible circuits, like other electrical interconnects, are subject to either receiving or emitting electromagnetic (EM) and or radio frequency (RF) interference. For critical designs, if allowed to occur, the performance of the assembly, or that of other local assemblies, can be compromised to the point of becoming non-functional. The difference between EM and RF interference is the frequency of the “disturbance,” with RF being in the radio frequency range and EM being typically 500 MHZ and higher. There are many potential sources of both types of interference within an assembly.

Around the world, different industries have applications and equipment where there will be changing temperatures, humidity, or moisture that can impact how a component operates or processes signals. There may also be instances where a product needs to be at a certain temperature so that it may be processed, such as a liquid chemical or food product that has to be at the right temperature, so that it will be fluid enough to be packaged into containers.

Challenges in Dynamic Flexible Circuit Board Design

Written by Paul Tome
Posted on January 21, 2020 at 9:43 AM

Dynamic flexible circuit boards have the capability of solving many interconnect and packaging challenges in designs that require repetitive motion. They allow for extremely high-density interconnects while consuming a very small amount of space. However, these applications have a different set of design rules than that of a “one-time” or “bend-to-fit” static application.

Advanced and Non-Standard PCB Manufacturing Capabilities

Written by Al Wright
Posted on January 16, 2020 at 9:12 AM

There was a time when the PCB manufacturing industry included a fair number of bucket shops, so called because much of their processing was done in small portable tubs filled with etchants, solvents, and other mysterious solutions. They cranked out very basic, low-cost, low-complexity PCBs, using equipment and methods that were questionable at best. Their business and environmental practices were often similarly questionable.

Differences Between Coverlay and Flexible Solder Mask

Written by Paul Tome
Posted on January 7, 2020 at 9:39 AM

Flexible circuits have two material options available to encapsulate the exposed outer layer circuitry: polyimide coverlay and flexible solder mask. While both perform the same basic function of insulating the external layer circuitry, each has different characteristics and capabilities that address specific design requirements.

Posted on December 18, 2019 at 9:41 AM

Anyone who has been in the business for more than five minutes understands that the rate of change in electronics hardware development can sometimes be overwhelming. Just this year at the University of Michigan, a team has developed the world’s smallest computer, measuring just 0.3mm to a side, smaller than a grain of rice.

Advantages of Developing Effective Inventory Management

Written by Bryan Nolan
Posted on December 10, 2019 at 9:21 AM

Running production operations is a daunting task for manufacturers. You want your operations to be highly productive, flexible with the changing needs of customers, and to run efficiently. At the same time, you want to develop ways to reduce process costs without reducing the quality of works-in-progress (WIP) parts or finished contracted products.
