Please Read this Before Requesting Training on this Tool

 

Notice 1:This tool produces bare copper boards and limited 3D milling. The image to the right is an example board produced by an
LPKF mill. This board still needs to be removed from the larger stock material. 

Notice 2: Birck does not provide cutting tools to operate this tool. Before you can be trained on this tool, you will need
purchase the relevant tools for your production. For new users it is recommended to purchase the Starter Package.

Notice 3: Due to Prior issues with the LPKF mill, and extensive updates to the tool. Birck has decided to move this tool to a "selective approval" use case.
This means each professor/group should select one student to be the user for the entire group and all fabrications at the tool should be completed by that user or a BNC Engineer.

The goal is to have that user on the tool frequently so they become, and maintain, proficiency at a level that will reduce potential damage to the tool due to operator errors.

 

Ok, so I read that, and I don't think it's a good fit.  Now what..?

A simple google search for prototype PCB fabrication will turn up many options for online short run PCB services.
Review their capabilities carefully as they do vary from service to service. Some offer same day turn around!

Technology Overview 

 The modified LPKF milling machine now makes use of a "Duet 3" 3D printer control board and it's respective interface. This along with a revamped z-drive and spindle motor allow for the use of true 3D milling operations as compared to the prior 2D.
