Making a double sided circuit board at home can save you a bundle of money. Mikey describes how to use a inexpensive CNC to make a two sided circuit board. T...
PCB alignment base for milling. Milling a double sided circuit board is quite challenge without a proper setup. The copper layer on the clad laminated sheet is very thin, to mill this layer evenly, we need the surface of the copper sheet to be parallel to the movement of the Z-axis. The tool used for isolating the copper traces also needed to ...
Thin Double sided tape to fasten the PCB clad to a scrap cutting board for the CNC. This should not be the backed but rather the thin-film one often used for fabrics. A Finishing brush with ...
Double-sided tape works okay, but for added measure, you can use a screw through this hole into the MDF to ensure the PCB stays in. Note that the warping that the screw may cause will be filtered out when running the Auto-level function in Chilipeppr. First set up your PCB. Start your bit at (0,0,0), as close as you can, it doesn't have to be ...

This little milling machine is great for quickly making prototypes of PCBs and parts. In this guide we'll take a look at the process of milling double-sided PCBs. In this project, we'll make a breadboard adapter for the Adafruit Circuit Playground. Connecting …
All we need to do is to solder a scrap wire to a corner of the PCB clad, and fasten it to an ideally flat piece of scrap wood using generous amounts of double sided tape. Once this is complete, the...
Phase 3 – Etch the PCB with the Milling Machine The designer must understand some of the tools and machining process to ensure the proper conditions for milling a PCB out of bare copper clad. The milling machine etches away the copper as instructed by the artwork files and results in a nicely made single- or double-sided PCB.
Through-hole Plating of Printed Circuit Boards For double-sided and multilayer printed circuit boards. LPKF ProConduct is handy, extremely fast and easy to use. All holes are plated through in a parallel process. ... For PCB prototyping, milling of polyimide stencils with LPKF circuit board plotters is a genuine alternative to laser-cut steel ...
One PCB mill in the budget-priced category is the Prometheus from Zippy Robotics Inc. in Northport, N.Y. The $3,000 machine has a spindle that runs at 50,000 rpm and has a runout smaller than 2.5 microns. It lists a precision of 0.15625 mils (4 microns) in X and Y, and just 1.25 microns in Z.
Milling a double sided copper-clad board using the S63 Protomat. The tutorial aims to cover the steps involved in milling a two layer copper-clad board with through hole components. This tutorial will also introduce the LPKF ProConduct process for plating through-holes and vias. List Of Symbols . A summary of symbols you will see in this tutorial

This video shows my first attempt at doing a double sided board. Either as 2d (.dxf) file or a 3d (.stp) file. The lpkf protomat mechanical pcb milling options are now highly automated and more precise than ever before allowing for quick turn development within …
The "Holy Grail" of DIY PCB making to me is: The Double Sided Board With Fine Pitch SMD Parts. In this "How To" I'll show you my special technique for making great two sided PCBs in the home electronics lab. My technique uses presensitized PCBs. These presensitized PCBs are a little like photographic paper.
The best I ever got was clamping a sacial block of material (mdf was fine) and then using double sided tape for attaching the pcb. Check flatness and shim the block until it was flat (often a single feeler gauge in a corner was all that was needed for success or failure).
18 Dec 2017 04:24 #51701. by bmartens. Double-sided PCBs, Eagle and UCCNC was created by bmartens. I've designed a circuit in Eagle, and have ended up needing to make it double-sided. This is my first significant project in Eagle, and the first circuit to mill on my Stepcraft 2/600. I found a user-language program written by Kina Smith:
For double sided circuit, it's even more challenging. After mill the first side and flip over to the second side, the CNC machine will need to an exact reference (0 and 0 on X and Y axis). To make this process easier, I design a setup (base or fixture) that have a to surface is milled with a flat end mill to make it parallel to the Z axis ...
Top and bottom layers: making vias by means of PCB rivets on a double-sided milled PCB. The milling job is quite bad here: the traces were not cut properly on the top layer (left side, check why here), and the layers were mis-aligned after the board was flipped over to mill the top side...

Milling 2-sided PCB's. Before xmas I did a lot of PCB milling for a client. Compared to getting the PCB's commercially made somewhere, this is the equivalent of rapid prototyping for circuits. Getting a board produced in the UK, Germany or Asia will typically take at least 2 weeks (but often 3).

4. Load the mill Insert an empty fr4 substrate into the mill. My current mill does not have a vacuum plate, so I use double sided adhesive to attach the PCB to the plate. It it very important that the top surface is completely flat and in level with the mill x-y axis. If you planar the area first with a router the result will be better. 5.
Milling Save Subscribe Setup Fixture In order to cut precise double-sided boards, we need to install the alignment bracket. This comes with the machine and is secured to the edge of the spoilboard with three screws. I suggest installing the …
2. A Double-side PCB can be completed within one hour when thermal transfer is used. In spite of possible misalignment calling for multiple times of thermal transfer , a double-side PCB can be fabricated within three hours at most. CNC drilling and milling machine, however, takes more time, at least four hours.
Double Sided Boards. We can mill a double-sided PCB design on the Bantam milling machine, by simply flipping the board over to mill the back. However, there are some important steps to be take to be sure it is accurate. To start, you must use the PCB bracket when milling a …
Use some strips of double-sided tape to glue down the copper clad board to the spoilboard of your machine. Make sure that this part of the spoilboard is completely level, for example you can level it with milling a pocket (just needs to be 0.5mm deep) into it. Or use an autoleveller. For the GRBL users this can be done by using chilipeppr.
The steps below assume a double sided PCB will be isolation routed, drilled and cut from a larger blank PCB. The image below shows the Line Grinder software displaying the Isolation GCode which will be executed in step 6. Note the PCB is shown at about 3x magnification in the image below. 2) Mount a Throw-Away Piece of Wood to the Bed of the Mill
It should be somewhat bigger than the PCB itself. - Use a mill to by mill away a millimeter or so of the surface. This will compensate for any deviations when mounting the fiber board blank and ensures the surface is planar. - If your PCB is 1.5mm thick, mill a pocket for the PCB that is a little less than the thickness of the PCB.
