There are many ways to cut panels out of a large board. In this case the board is a 12 inch X 12 inch board and it contains eight individual circuit boards. There are shears that can be used to cut out individual boards. Some people also use things such as band saws and jig saws but I have found the fiberglass dulls the blades very quickly. I have had good results using a 10 inch abrasive metal cutting blade mounted in a table saw.
Line up the work and pass it through the blade. Watch the fingers…
Here are some boards that have been cut out. A good artwork layout pays in this step with little material removal.
Another picture of a cut out board. Look at the cut edges and use the side of the abrasive blade to square up any edges that don’t look good.
[…] Drilling holes in PCBs is one of the most boring tasks I have ever done. Positioning the board isn’t the hard part, pulling the drill press lever up and down at a rate that won’t break the fragile tiny drill bit it the thing to watch. This PCB Hole Driller project will solve this issue by allowing you to simply position the board and hit a foot switch. The system will automatically drill a hole at the rate selected. This is sure to get some good mileage out of those fragile drill bits that love to snap. […]
[…] Making your own PCBs boards is a time consuming task. If I need to make 1 or 2 simple boards I don’t mind spending some time and building a few but if you will ever need more than that you better look at getting them made by a professional PCB manufacturer. This means that drawing a picture of your copper layer in a graphics program and printing it on a transparency won’t exactly cut it since all of the PCB manufacturers will need Gerber and Excellon files. But with these files they can work their magic. […]
