PCB Material Selection
Types of material available. Circuit Board Material The circuit board is made up of the core (substrate) and the laminate. The core is the dielectric (non-conductive) portion chosen based on dielectric constant. Laminates provide the copper foil or surface. Laminates themselves, may also be used as core material in some constructions. Substrates Substrates are dielectric composite […]
Future of Printed Circuit Boards
Printed circuit boards have continued to advance and evolve since their invention back in the 1940’s. Today, PCBs are smaller, thinner, and denser in circuitry, than could ever be imagined at the beginning. They are also produced more efficiently and at higher volumes due to enhanced manufacturing technology and design software sophistication. As a key […]

The 8 Step Problem-Solving Methodology
The eight-step problem-solving process is commonly employed as a problem solving and preventative corrective action methodology. This method defines a step-by-step process to follow from problem identification to problem solving (preventative) actions. 1. Problem Identification Identify the problem and why it’s a problem. Define how it was identified and the impact to the business. 2. […]
High Material and Labor Costs Continue to Challenge the Electronics Manufacturing Industry
Recent information from sources such as the IPC indicate that supply chain challenges remain a major problem for manufacturers and OEMs, but that the peak may have finally been passed. Lead times remain higher than in the past (pre-covid), updated economic data and responses from global electronics manufacturers finds that high material and labor costs […]

PCB Materials for High Speed Applications
Key material performance parameters are used to determine suitability of PCB materials for high frequency PCB applications. These include dissipation factor (Df), and dielectric constant (Dk). For digital circuits, and their steadily rising speed requirements, choosing the wrong PCB materials can have devastating results (such as poor plated-through holes or impedance discontinuities). Material selection based on these […]
Using a Multi-meter to Test a PCB
PCBs are simply an electronic component base where various components are positioned and soldered in place. PCBs are made by etching the copper layer on the core laminate with the electrical circuit (layout). The most popular method is based on utilizing a ferric chloride solution, although there are methods available as well. If etching is improper, […]
