Why HASL Surface Finish for Flexible Circuit Boards Is Not Recommended

Written by Paul Tome
Posted on October 26, 2022 at 8:48 AM

The hot air solder leveling surface finish (HASL) is the second oldest surface finish available for printed circuit boards and up until a point in time was virtually the standard surface finish used in the electronics industry (originally with leaded solder and more recently the RoHS version with lead-free solder).

Flexible Circuit Boards with Lap Joints: Design Considerations

Written by Paul Tome
Posted on October 18, 2022 at 8:51 AM

Flex circuits have many unique capabilities to solve design challenges. One of these is a lap joint capability that allows a flexible circuit board to be directly attached to another circuit or component eliminating the need for any type of connector.

How to Avoid Fracturing Traces in a Flexible PCB Design

Written by Paul Tome
Posted on October 6, 2022 at 8:19 AM

Contrary to some customers’ perspectives, flex circuits are not indestructible. As with any part that contains a metal if it is bent or handled beyond its physical capabilities it will break. In this blog, we will cover the 3 main causes of fractured or cracked circuits in a flex design and how to prevent them from occurring. We’ll also review how to determine the minimum bend capabilities of a flexible circuit board design.

Why Heat Dissipation is Important in Flexible Circuit Board Design

Written by Paul Tome
Posted on September 6, 2022 at 8:23 AM

Heat dissipation is the ability of a part, whether a circuit or any other component, to take the heat that's being generated by a component or an element of the design and to distribute it, dissipate it, and make the heat go away, for lack of a better phrase. This prevents the temperature of the part from continuing to elevate as the device is operated.
