Making PCBs with CNC

CodeLock1

Rui written an article on how to build your own PCBs using a CNC machine. Rui Cabral writes:

The PCB manufacturing method i used before buying my CNC machine was the lithography method and worked as follows:

First i printed the board design on an acetate sheet.

This sheet was placed over a pcb with a light sensitive coat and placed under UV light for several minutes.

The pcb was then immersed in a solution of caustic soda to remove the photo sensitive material that was “damaged” with the UV light.

The pcb was then immersed in a Ferric Chloride solution to remove the copper.

After the copper being removed i then washed the pcb to remove the chemicals and then i needed to cut the plate and finally drill the pads.

Brainboard v2: Demon of CNC controllers

20150322012942-pet

3D Printers, CNC Mills, Laser cutters, Pick n Place robots…Brainboard v2 will rule them all!

Brainboard v2 is a modular CNC controller board based on LPC1768/69 Cortex-M3 chip. Due to its modular design it allows easier upgrades as per requirements and easy replacement if there is any broken part. It runs on open source Smoothie modular firmware and is targeted at 3D Printers, Laser cutters, CNC Mills, Pick and Place and other small or Mid-size CNC machines. Upgrade your machines for higher performance and features.

3D Printed Desktop CNC mill

by Elektron8 @ instructables.com:

Welcome to this project. The CNC UNO is a small desktop CNC Mill that can be used for hobby engraving and routing, PCB milling and education. It is mainly made with 3D Printed ABS plastic parts and plywood. Before starting this project, please observe that this machine is not intended for precision work nor for cutting hard materials like metal. As the machine parts are made of plastic and wood, the machine will flex under heavy load and that is why this project is for fun rather than any serious application. That said, it is a great little machine for hobbyists that want something to play with without having to spend a fortune.

It’s a cnc using Arduino UNO R3 , GCode Sender and GRBL. The cnc is made of wood thanks to the help of my father. It has taken us many hours to do the mechanical part however the electronic part is faster to do, but is very gratifying. I based my project on these videos and I have received much support from the author of the first video.

The total cost of the project is about 450€.

(semi) Automated drill press table for PCB manufacture

table_complete

Drilling holes in homemade PCBs is greatly simplified with an computer-driven coordinate table on a drill press.

The clue is the on-the-fly calibration technique, so it does not matter where exactly the PCB lies on the table. You only need to move to two drill holes by hand, then the computer knows how to drive to the other holes.

Desktop milling machine creates PCBs and packaging

othermill

by Michael Dunn @ edn.com:

Version 2 of the desktop Othermill milling machine is now available, and it’s accurate enough for a range of machining tasks, including double-sided PCBs.

The machine can handle a range of materials, like brass, aluminum, wood, and plastic. For PCBs, FR-1 is recommended over FR-4. With a small milling bit, footprints as fine as TSSOP & TQFP can be created. Solder paste stencils can also be cut using the mill.

For a good walkthrough of PCB creation, read this blog by Tom Simon, a user who liked the Othermill so much he joined the sales team.

Cheap Arduino CNC

by siemenwauters @ instructables.com:

this is my first instructable. i show you updates on my cnc machine which will cost about 200 euro’s for still decent quality.
don’t hate if you don’t like this instructable, I’m just an 18 years old student from belguim sharing his ideas and creations with other people. because i think working together and sharing idea’s will make better projects.

this is what the machine looks like right now. ill post new photos every time i advance building

i know my video’s are not the best. i’m working hard to show you how everything works so it would be nice if you watched at least a peace of all of them to support my project.

Piccolo, a pocket sized open source CNC-bot

cnc-600x400

Piccolo, a pocket-sized stand-alone CNC platform from DiatomStudio:

Using laser-cutting, off-the-shelf hardware and Arduino, you can make your own simple 3 axis robot. Attach a brush or pen to make a quick drawing robot, or extend Piccolo with sensors, custom toolheads, or by using multiple Piccolos together. Experiment with 2D or 3D digital fabrication at a small scale!
