PCB Manufacturing - Processing Without the Problem of Voids

Written by Angie Brown
Posted on January 10, 2022 at 10:12 AM

What is a void in the printed circuit board (PCB) world? A void is an un-plated area within the hole wall of the PCB drilled plated hole. Voids in hole barrels can be equally problematic in all types of PCBs. The number of layers contained within the PCB plays a part in the cost of the completed circuit board. The more layers within the card the more cost is added for manufacturing. However, a two-layer part can also be expensive to scrap.

Custom Cable Assembly Extrusion 101 - Single to Multi-Conductor Cables

Written by Steven J Goodman
Posted on December 28, 2021 at 10:18 AM

The process of extruding metals, plastics, and other molten materials is common and necessary to produce many of the products used in the world today. Items such as drinking straws, PVC pipes, and even coat hangers also rely on extruded raw materials for processing. No different than a child’s playdough set or making homemade pasta, material is forced through an extruder die creating the long uninterrupted shape of whatever material is being made.

SolidWorks Design: How to Approach Editing Other People’s Work

Written by Darren Casey
Posted on December 22, 2021 at 10:21 AM

Although there are best practices when it comes to 3D modeling, every designer ends up developing their own style of modeling. This can cause challenges when you are tasked with working with someone else’s model. It can become frustrating when you go to make an edit that causes other parts of the model to change or fail entirely.

How Hot Can a Flexible Polyimide Heater Get?

Written by Chris Perry
Posted on November 23, 2021 at 9:41 AM

Flexible heaters are essential devices to provide heat to specific areas of an application. They are used in a wide range of industries including aerospace, medical, food service, and military. When applying heat to a surface, the right types of materials must be used for the heater. The heater must be flexible enough to bend and wrap around curved surfaces while avoiding working parts. They also have to be able to provide optimal heat transfer without damaging either the application or the heater’s elements and circuitry.

Using a High Flexibility Silicone Wire and PTFE Wire Design

Written by Steven J Goodman
Posted on November 18, 2021 at 10:48 AM

There are several reasons to choose silicone or PolyTetraFluoroEthylene (PTFE) jacketed cable when designing a custom wire harness. Both jacket constructions are known for their high-temperature resilience and extreme flexibility. The main difficulty of selecting a PTFE is the fact that they can be a bit hard to come by.
