DFM (Design for manufacturability) analysis of incoming Gerber files is a standard and important process in any PCB factory.

iPCB-DFM’s purpose is to perform this process automatically to find potential production issues with your PCB design, saving time and effort for you the PCB designer, and the PCB manufacturing engineers who are going to produce your PCB.

Based on 25 years of PCB manufacturing experience, we have a massive collection of PCB DFM rules built into this software, allowing it to analyze up to 24 kinds of specifications.

It also has powerful features such as quick panalization, PCB simulation view, direct Gerber editing, and can even help you count how many SMD pads in your design!

Why do you need iPCB-DFM?

If you’re an electronic engineer, you don’t want to send your PCB Gerber files for manufacturing without checking that your design and file formats match your factory’s production capability; If you are a purchasing manager without much knowledge of PCB manufacturing processes, this tool can help you better understand the specifics of the PCBs you are ordering, making it much easier to communicate with PCB suppliers.
