How to Choose a PCB Manufacturer

When it comes time to choose who to work with, you will need to determine which PCB CM will be the best choice for what you need to be done. Some CMs will have more experience and capabilities than others, and it will pay to have a better understanding of who they are and what they have to offer. Let’s look further into these different services so that you will have a better idea of how to choose a PCB Manufacturer that will be right for your needs.

How to Develop the Best PCB Schematic Design

Having an unorganized schematic doesn’t just affect its readability however, it can also create problems for how the circuit board is designed and manufactured. To avoid these problems and create a clean and readable schematic, here are some tips on PCB schematic design capture to help.

SMT Component Placement: Part 2 ― Accuracy

If the parts on the board aren’t placed accurately, there will usually be problems in how the board is assembled. There are many factors that can contribute to this including whether the physical parts themselves are within their manufacturer’s tolerances, and how they are used on the circuit board. Let’s look at some of these issues, and some recommendations on how you can design for better SMT component placement accuracy.

SMT Component Placement: Part 1 ― Tolerance

For a successful assembly of a circuit board, the components must be the correct size and shape and placed in the right locations. Not only does this mean that the design of the board must adhere to tolerances governing the creation of the SMT footprints and their placement, but the physical parts must be correct before assembly can even begin. We’re going to look at these SMT component placement tolerances here, and how those tolerances impact the way a PCB is designed.

The Top Five High Current PCB Design Tips

Working with high power circuits does involve some different PCB design techniques, such as the width and weight of the copper that is used on the board. Let’s take a look here at some of the most important high current PCB design tips that you should know about to avoid any unnecessary drama.

What is PCB Schematic Capture?

Each circuit board that you see being produced by a PCB contract manufacturer first started its life as a schematic. Someone placed the symbols on the schematic and connected nets to the symbol pins in order to create the design data that would drive the layout of the PCB. Let’s take a closer look at what PCB schematic capture is, and some of the do’s and don’ts that you need to be aware of as you design your printed circuit boards.
