Cadsoft Eagle is a freeware circuit and PCB layout program well known among electronic hobbyists. One way to turn your design in actual PCB is to submit it to a PCB manufacture and have it shipped to you. But what files you should submit? This article discuss about how to save Eagle designs as industry-standard gerber files that are accepted by every manufacturer. Check the steps needed to save your design on gerber on the link below.

I have been using the toner transfer method for about 9 years with great results. Occasionally I would need a board with finer traces and I would use UV method. My exposure setup allowed only a single sided board to be made and it was composed of a 30cm UV tube, some holders, a table, board and film. Exposure time was rather long as the tube was far away from the board.A few months ago I was looking for some LEDs at one of my suppliers and found that the also had UV LEDs. My mind went directly to upgrading my not so great setup, so I began looking on the internet for info. It turns out some other people have done it, and this instructable confirmed it was really possible. A LED UV box has a clear advantage over a tube one: it can be made in any size, depending on the needs.I bought 25 LEDs and began to experiment. This way I was able to find a compromise between LED density (spacing), distance between LEDs and board and cost. I wanted something compact, I don’t make large PCBs and those 30cm tubes were not right for this job.

This article will guide you through the steps needed to make your own printed circuit boards.
First of you’ll need to make the layout you will be transferring to your copper board in a CAD program. I use CadSoft’s Eagle software, which I find easy to use.

This article discuss how to apply solder paste on PCBs step by step. Read about it on the link below.
Solder paste placement is probably the most critical stage of the PCB assembly process, and most assembly problems can be traced back to poor paste placement. If you want to avoid time-consuming manual rework on your assembled boards, it’s essential that you have a clean, precisely positioned layer of solder paste. A few extra minutes ensuring that your paste layer is correct can easily save hours of rework with a hot air gun and a soldering iron later. Thankfully, there’s nothing magic about it.

Ever wondered having your own UV exposure box in your lab but couldn’t get one because of the high cost? Don’t kill your dreams so easy. Now you can make your own UV exposure box and print your own printed circuits boards in your home. In this article we will find out how to construct the appropriate box and the required electronics inside it. This is a basic guide and not a super detailed guide. Many easy to understand thinks are missing. Don’t loose more time, let’s start with the specifications.
