Making a Back Plate using a cheap Chinese laser cutter and coral laser.
To make a Back plate for the MSI Ge-Force GTX 980 Ti wasn’t an easy task when you literally know nothing and when asking questions all you ever seem to get is people saying use other software, however this would cost a fortune. So we set out to make it using just the tools we had.
First off using a regular scanner we can the back of the MSI Ge-Force GTX 980 Ti using a 100% ratio so we would get a like for like copy of the back of the board. This is important as we need to measure up the board so we can replicate it digitally. If you get lots of Black around you print out like we did just lay white paper around the PCB so that you get some clean lines to work with.
Once completed test the photo copy of the back of the PCB against you Ge-Force 980 Ti card and make sure everything matches up correctly. This took us a couple of attempts but didn’t take long.
Once we had the scan we simply took measurements of the now flat Paper PCB such as the 5 holes were going to mount the plate to and the surrounding edges that we wish to plate up.
Next we opened up coral laser and imputed the rectangle size and cut offs needed and then place the correct size holes corresponding to our back plate. This Made life ultra-easy and not much messing was needed to get the sizes correct.
Your back plate is now ready to go. However we would like to show who make the MSI Ge-Force GTX 980 Ti so next we took a copy of the MSI logo from there Logo page here ->

And we added the dragon to the back plate. We had to adjust the dragon a little just so that the laser had clear lines to cut and didn’t over cut on some parts of the dragon. We didn’t like adjust the mascot but for the plate to look good with the cheap laser we didn’t really have much option.
Next we added the MSI logo and sizes it to the back plate and then added the wording for the GTX 980 Ti (we didn’t add Ge-force as it would have been to much). One thing we noticed was the lettering would have not worked as it was plain and the 0’s in 980 would have feel out and would have needed gluing in which is a pain to do. So I nipped over to
http://www.1001fonts.com/stenciled-fonts.html?page=9&items=10 and chose a stencil font and installed it to the PC and used that to create the correct type of wording. This made life so much easier than faffing on.
Now to create test peace’s we didn’t want to go slicing and dicing expensive peace’s of plastic to make sure ever thing fitted so we simply laser cut sheets of paper and tested them on the back plate, after a few minor adjustments to the design we finally got what we needed and moved over to running a 1 off test peace in 3mm ply.
**Pictured below is a test peace in 3mm Ply. This was cut at power 40 on the laser and speed 6mms. It cut through the first time which is perfect for our needs and as a test peace. (plz remember if you a pro you may know better, how ever I’m not).
As you can see the images of the dragon still needs some work as we lost the eye but getting there slowly.
