Why PCBs are green

Perhaps you have asked yourself: Why are printed circuit boards green? The most commonly used base material for printed circuit boards is FR4 and is made from an epoxy resin and glass fibre. Epoxy resin is a light, almost transparent matt yellow colour which deepens with increasing thickness. The printed circuit board, on the other […]

Global Semiconductor Shortage

The shortage of materials has worsened further; there is no relaxation in sight. That’s why the everyday heroes are our purchasing staff. For weeks, our team has been giving its all to bring in the electronic components so that we can deliver your PCB assemblies as quickly as possible. We explain the unprecedented situation on […]

Designing with BGAs for manufacturability and cost

Designing PCBs with ball-grid array (BGA) packages on them can be tricky; getting them manufactured can sometimes be even trickier! Here we’ll discuss what to consider when designing with BGAs in a way that makes them easier to manufacture and often also cheaper. Important: all figures in this article are correct for the time of […]

Surviving Shortages Together

Electronic components are increasingly difficult or even sometimes impossible to source. The only way to help overcome this situation is to use our Parts Reservation service. See our article below. Even with these challenges our production will continue throughout the summer and our customer support team will be available and ready to help when you […]

Sorting out Drills and Cutouts

Components, connectors, cases, cables, modules, and other things that get attached to our PCBs may require space that isn’t a simple round drill hole. For those special gaps we create cutouts. Let’s first define what we’re talking about because there’s no industry consensus on some of these terms. We can distinguish between two types of […]

Impedance Calculations

Because our heart beats for the European electronics industry, we are involved in Working Groups, the Promotion of Young Talents and are actively involved in Electronics Community Events. It is very important for us that we share our knowledge and use it to support you. In this newsletter, we have also compiled tips and tools […]

Complex Story of PCB Thickness - Featured Image
The Complex Story of PCB Thickness

When we design a PCB we think of its final thickness in discrete values: 0.2mm, 0.8mm, 1.55mm, 2.4mm, and others. But the reality is that we will almost never get a PCB back with those exact thicknesses. Here I will discuss why that is, the many factors that affect boards’ final thickness, the tolerances we […]

Defining Defined Impedance

All functional circuit boards have tracks that guide electrons from one place to another in order to complete a circuit that ― hopefully! ― does what we want. These tracks have length, resistance, capacitance, and inductance with a magnitude that depends on their physical attributes, relationship to other conductive and non-conductive materials nearby, and the […]

Applying Carbon Contacts to PCBs

Conductive carbon ink is added to a finished PCB in order to provide a robust and long-lasting electrical interface with another mechanical component, such as a key or dial. It does that in two main ways: it raises the shallow copper contact above the surface of the PCB; and, it protects the PCB contact from […]

Covering vias

Vias are plated holes that connect signals between layers, and are typically smaller than ordinary plated holes that are used for soldering through-hole components. What also makes them special is that they’re usually not the destination of a signal, so they create a physical ‘interruption’ that sometimes makes an impact on functionality. Types of vias […]

Castellations - Featured Image
Castellations on a PCB

Castellations— or castellated edges, plated holes on the board’s edge, plated half-holes — are rampart-like structures along the edges of a printed circuit board. Their main advantage is that they allow an electrical connection to another board through the side edges of the board, without additional components. Pretty neat! Castellations are manufactured by creating ordinary […]

Glossary

To simplify communication Eurocircuits uses abbreviations for many of these technical terms. Most of the technical terms and abbreviations are international standards in the Printed Circuit Board manufacturing industry. However to make it clear to everyone involved, we here present a list of technical terms and abbreviations along with their explanation.
