Circuit Board Milling Machine

The circuit board printer is a machine capable of milling custom printed circuit boards (PCBs). It will take a sheet with a layer of copper on top and on the bottom and cut the traces. It is ideal for quick and inexpensive prototyping of circuit boards. It is located in the downstairs Electronics Lab of the OEDK.

To print using this milling machine, you will need to create a gerber file from a circuit board plotting program. You can find these tools on campus (Orcad), or you can download free programs for academic use - Eagle is one example. Eagle is installed on the OEDK printers. After you have created the gerber files, you need to save them to a flash drive and use them at the PCB mill to create your circuit board. Carlos Amaro can guide you in the proper use of the PCB mill. After you have created the PCB, you can then solder in the components at the soldering station.

Some things to keep in mind when designing your board

Package type: A component is packaged a certain way to be soldered into a circuit board. This is called the package. There are many different types: DIP(dual inline package) is what you will have seen in most of your labs for integrated circuits, SOIC (small-outline integrated circuit) is a smaller surface mount package, etc. You can find a guide here.

Integration with the rest of your components: If you will be connecting your PCB to other components, it is recommended that you spend a great deal of time planning how you will connect the PCB to those components. There are connectorsdesigned specifically for this purpose. The effort you put into the initial design will save you a lot of headache later. Think about the inputs and outputs for your circuit, and ask Carlos Amaro about your design before you mill it or have it sent off for milling.

Outside PCB Manufacturers.

The OEDK PCB milling machine does not however make through holes in the PCB, and if you require a very fine circuit board, you may want to use an outside vendor. 

Some examples of outside vendors are:



Advanced Circuits

You can get 3 3.8 x 2.5 inch boards for $51. These are also double sided, no silkscreen, no solder mask, 1 day turnaround. To use this service, you must use their (free)proprietary software. They do not accept Gerber files.

Their lowest price service is $95 for a batch of two boards of up to 9 square inches, with 24 hr turn around. These are double sided boards with no silkscreen or solder mask.

They have a $33 each special for two layer boards up to 60 square inches, with solder mask and silk screen. The lead time is five days. The minimum quantity is normally four, but this is waived if you are a student (i.e. you can order a single board for a total cost of $33 plus shipping).
