PCB Design Tip of the Day

Where do the PCB Design errors grow?

A lot has to happen before a PC board gets into an end user's hands - many different processes and people are involved in getting a device designed and built. The more people and processes involved, the more opportunities there are for errors to crop up. Quality isn't just about the assembly. It's about information and knowledge transfer.

Our San Diego PCB layout specialists take schematic diagrams from design engineers and create the layout for a high quality PC board. The hand off or transition from schematic design to layout is a critical point in the process that often doesn't get the respect it deserves.

Tip of the day: Check your netlist for errors

While working on a complex schematic, it’s easy to make a mistake or leave something out. As such, broken netlists are a very common issue we encounter. Usually the errors are small, but sometimes we run into glaring issues with a customer’s file. In fact, recently a customer submitted a netlist without any pin numbers!

A simple way to check for errors before you submit your netlist to us is to export it: if you receive a syntax or other error message from your program, then you know you’ve got a problem. If you’re lucky, the error message will be specific enough to tell you where the issues are located.

In addition to exporting, most schematic capture programs come with at least one verification utility you can use to look for issues. Taking these quick steps will help ensure your netlist is correct and ready for production.
