Flex PCB Design Options: PCB Pattern Plating vs. Pad Plating

Written by Paul Tome
Posted on May 11, 2022 at 9:21 AM

Flexibility is a critical element in most flexible circuit board designs. Whether it’s to meet a tight “one-time bend-to-fit” application or a “dynamic” infinite bend cycle application. To meet these requirements, a flex circuit design must be kept as thin as practically possible, use the correct copper type, and utilize the correct copper plating process.

Mechanical bend reliability is a critical element in a successful flex or rigid-flex PCB design. One area that can have a significant impact is the transition line(s) that occurs from a rigid area, in a rigid-flex circuit design, or from a stiffened area, in a flex circuit with stiffeners design, to the flex layer(s) only areas.

We get many inquiries from our customer base regarding updating or converting an existing design from its current configuration of rigid printed circuit boards interconnected with a wiring harness to a rigid-flex printed circuit board. With our experience, we can quickly determine if a conversion option is worth investigating further. We can also see how some are relatively obvious that they would need a complete redesign to convert.

Flex circuits have the capability of utilizing a wide variety of connector options. The list, with a couple of exceptions, includes all connector systems that can be used on rigid printed circuit boards (PCBs) plus a couple of additional systems that were specifically designed for interconnecting flexible circuits to rigid PCBs or wiring harnesses.

Rigid-Flex PCB Design Limitations for Laser Drilled Holes and Slots

Written by Paul Tome
Posted on August 19, 2021 at 11:11 AM

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.

Designing Flexible Circuits for High-Temperature Applications

Written by Paul Tome
Posted on August 3, 2021 at 10:42 AM

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.

How Flexible PCB Material Selection Affects Lead Times

Written by Paul Tome
Posted on July 21, 2021 at 10:10 AM

There are a very wide variety of materials available to construct a flexible circuit. The materials range from different types of copper, copper thicknesses, core/coverlay and adhesive thicknesses, adhesive types, stiffener types and thicknesses, PSAs, shielding films, flexible soldermask colors, etc. Inadvertently specifying unique or non-standard materials can result in significant delivery delays as they may not be standard stock at either the manufacturer or the supplier.

Benefits of Using Air Gap Rigid-Flex PCB Constructions

Written by Paul Tome
Posted on July 8, 2021 at 10:44 AM

Advancing technology has impacted rigid-flex PCB designs in the same manner as rigid printed circuit boards. Increasing interconnect requirements and smaller form factors require higher circuit densities and increased layer counts. The impact of these elements on rigid-flex circuit designs is potential reliability issues both electrically and mechanically.

Flexible PCB Line and Space Limitations to Be Aware Of

Written by Paul Tome
Posted on May 12, 2021 at 9:30 AM

In some areas of a flexible circuit board design, the trace widths and spacings, trace to pad spacings, and via pad sizes are the same as used in rigid circuit boards but will differ in other areas. This is due to the flexible nature of the polyimide materials used, the type of material used to encapsulate the external layers, and the unique plating process used for most flex circuit designs.
