Full Netlist compare

If you load your IPC 356 format Netlist with your files, we will create a Netlist from your Gerber files and compare it with your IPC Netlist. If there are any shorts and opens, we will show you which Net they are on.

Precise analysis

We provide a precise analysis of our DFM with the exact location and real graphics.

Accept multiple drill files

You can indicate which holes require plating, and which layers they need to go through.

Alignment layer

For each layer in your Gerber files, we offer great DMF service and will provide you with a PDF file showing how the layer matches the drill holes so that any alignment issues will be spotted by you.
