What Are the IPC Component Spacing Guidelines?

To avoid designing a circuit board that isn’t manufacturable, minimum standards for component spacing must be adhered to in the design layout. Of course, there are many other factors to consider as well, including the electrical and thermal performance of the board, but designing for manufacturability (DFM) is just as important. There are industry standards that offer some assistance with this, however, and here we’ll look at how IPC component spacing guidelines can help as you design.

Eight Important PCB Panelization Guidelines to Know

While we may think in terms of an individual printed circuit board when designing them, the reality is that circuit boards are often laid out in a panel to help lower production costs. Let’s take a look at what a PCB panel is, and then the eight PCB panelization guidelines that you should know for circuit board design.

Six Best Practices to Ensure PCB Design Completion

In the first three parts of this series we have looked at the schematic capture process, placing components in the physical layout of the board, and finally routing the net connections of the layout. Now it is time to get the board ready to be manufactured, but before we do that there is one critical step that has to be done; running the design rule checks.

Five Types of Soldering Defects in PCB Assemblies and How to Avoid Them

In the manufacturing of circuit boards, there are also many opportunities for defects to sneak in and as with everything else, it is important to prevent them from happening. One area that can be prone to defects is when components are soldered onto the board. We’re going to take a look at some of the more common types of soldering defects here in this article and explore some design recommendations that can prevent them from happening in the first place.

Nine PCB Routing Best Practices

The goal of PCB design is to create a fully functional circuit board. However, the first goal-post during PCB layout is to get the board 100% routed. A layout begins first by setting up the design parameters and then placing the components to satisfy their electrical, mechanical, and manufacturing requirements. The only thing left after that is to connect all of the nets with traces. That sounds like it should be pretty easy, doesn’t it? Well sometimes it is, but most of the time it’s much more complex than people realize.
