Maximum Layers of a Flexible PCB Before it is No Longer Flexible

Written by Zachary Walker
Posted on November 29, 2023 at 8:41 AM

At first glance, the answer to the question “How many layers can a flexible circuit have before it can no longer bend?” sounds like a simple, black-and-white answer. However, this answer proves to be more complex than expected and involves a great deal of specifications before it can be answered.

Adhesives in Flexible Circuit Boards: Types and Their Uses

Written by Zachary Walker
Posted on November 1, 2023 at 8:33 AM

One of the key components in the stack-ups for flexible circuits is adhesives. From bonding coverlays to the surface to adhering stiffeners to rigidize the circuit to creating additional use applications for the circuit, adhesives hold many possibilities and can add another dimension of complexity to flexible circuits.

Pros and Cons of Using Flexible PCBs In Your Application

Written by Zachary Walker
Posted on October 19, 2023 at 8:57 AM

Applications that rely on printed circuit boards (PCBs) to control functions can experience difficulties when having operating components or when designed in slimmed or smaller sizes. Standard rigid circuit boards have to be made in specific sizes and dimensions, which can make it difficult when designing working components that could scrape against and damage the PCB.

Flexible Circuit Board Designs with Pressure Sensitive Adhesives

Written by Paul Tome
Posted on November 22, 2022 at 9:13 AM

The unique capabilities of flexible circuits allow for additional design elements that are not available in rigid PCB designs. A very common one is integrating Pressure Sensitive Adhesives (PSA) into the design. A PSA is a double-sided adhesive tape that can serve multiple purposes. The PSA is attached to the flex as part of the manufacturing process and the release film is retained on the exposed side to protect the adhesive until it is installed.
