Dating back to 1952, we are industry leaders and experts in all things printed circuit board (PCB) related, rigid PCBs, flexible circuits, and rigid-flex circuit boards combined, we know all the options and the difficulties in the fabrication processes. In this blog, we will focus on flex and rigid-flex PCBs what you should know and what to look for regarding the design and layout, as well as the importance of a successful data set and what is needed to prevent delays in engineering and manufacturing.

Typically, constraints are not something a designer wants to incorporate into a new project when first getting started on a new product. When you hear “constraint”, the first word that may come to mind could be “limitation”. Generally speaking, that word association is accurate, however, when dealing with CAD software it is not necessarily a negative thing.

With advancements in rigid-flex PCB design technology, the use of laser-based systems in the manufacturing process are very common in the industry. Not having laser drilling and cutting available would place significant limitations on what could be accomplished in a design and what components could be used.

Cable assemblies are needed across various industries and are utilized in goods that include consumer electronics, industrial products, mil areo, and even medical devices. Low cost does not mean low quality; in fact, low-cost cables are qualified for use on many high-reliability applications.

Many flexible circuit board applications require designs to be exposed to and or operate continuously at elevated temperatures well beyond that of standard room temperature. These requirements are above and beyond the requirements of component or connector assembly.

You may have encountered the acronym STP or STEP while learning about or working on projects that involve computer-aided design. But what exactly is it? A STEP file is a 3D-model file formatted in STEP, which stands for Standard for the Exchange of Product Data. STEP files are used to store 3D-image data in an ASCII format, following the standards defined in ISO 10303-21, introduced by the ISO committee in 1994. This specification created a file structure which could be recognized by multiple modeling programs, thus enhancing the ability for design data to be exchanged.

Customers requiring batteries for their products or applications have become savvier when it comes to the developmental phase of the battery packs. They understand that by having researched power requirements, dimensions of the pack compartment, battery chemistries, and cabling specifications, the customer can develop more comprehensive design documents. Then, the battery pack manufacturer can use these specifications to get started on the development and tooling stage immediately.

Revision control is the method by which manufacturers and engineers keep individual parts or assemblies documented and tracked. A more simplified definition could be that revision control is a part’s road map. In the world of manufacturing electronics, it is critical that revisions of any product are properly maintained and controlled.

When designing a custom battery pack, a topic that will come up between the manufacturer and the customer deals with the fuel gauge. The battery fuel gauge can be found in a range of everyday devices that we use, such as cell phones and computers. The function of the fuel gauge is to inform the customer on how much state of charge (SoC) and state of health (SoH) is left in the battery. The fuel gauge can predict the remaining capacity by measuring the voltage, battery temperature, and current.

Impedance controlled circuits in a rigid-flex PCB design is a common requirement throughout the industry in a wide range of applications. Having Impedance control, however, does create an additional challenge for designs that have very demanding minimum bend requirements.
