It’s helpful to include part numbers on the printed silkscreen layer. We edited the part library to make the pads smaller, and the separation larger. Sparkfun’s default footprint for the Nokia LCD connector had pad spacing less than 8mils. Sometimes the spacing on a part footprint is too small to be manufactured.

Here, the spacing between traces is too close. Eagle analyzes the design and highlights any areas that violate the design rule parameters.Ĭorrect any errors. Click the DRC icon (or, Tools->DRC) and load the design rule file. Download the SparkFun design rules (DRU) for BatchPCB, or the Olimex 8mil (DRU) or 10mil (DRU) design rules. Use Eagle’s design rule check to make sure your board doesn’t exceed the manufacturer’s production abilities. The traces are 8mils only until there’s enough clearance to use 10mil traces. The digital picture frame has 8mil traces around the tiny LCD connector, shown above. Slightly larger-than-minimum tolerances will reduce manufacturing errors. Just because they advertise 8mils, doesn’t mean it’s safe to make every trace 8mils. BatchPCB has 8mil minimum traces and spacing, and 20mil minimum holes.ĭon’t torture the manufacturer. Press the ratsnest button ( or Tools->Ratsnest) to fill in the empty polygons.īoard manufacturers publish specifications outlining their production capabilities, such as the smallest possible traces, spacing, and drill size. The ground fill is empty when the file opens. brd file with the freeware version of Cadsoft Eagle.
#EAGLE PCB ARCHIVE#
This design requires a double-sided board with fairly small traces.ĭownload the project archive (ZIP) from last week. We’re going to walk you through the process of preparing our digital picture frame PCB for production. Create gerbers, generic files accepted by any PCB fab house.Either way, you’ll submit gerber files to the board house.
#EAGLE PCB FULL#
If you’re looking for something smaller, services like BatchPCB and PCB-Pool combine small orders and submit them as a full panel. Gold Pheonix sells 155square inches of PCB panel for $110. Any PCB manufacturer will accept gerber formatted design files. The cheapest option is to submit gerber files like the professionals. Good if you need a few boards, expensive for a single experimental prototype. Most require a minimum order of one eurocard-sized PCB (100mmx160mm). Some board manufacturers, like Olimex, make PCBs directly from Eagle. The photo process makes nice boards, but requires a bit of equipment sensitized boards, developer, and an ultra-violet light source. Most PCBs in our how-tos are made with the photo-resist process. Toner transfer is the beginners’ favorite way to make a PCB because the investment in materials is minimal. You can use the gerbers to order a single prototype, or a full panel.
#EAGLE PCB HOW TO#
We’ll show you how to save Eagle designs as industry-standard gerber files that are accepted by any PCB manufacturer.

There are several ways to turn an Eagle design into an actual printed circuit board (PCB). We use it for all of our hardware designs. Lots of open source hardware is designed in Eagle, and it’s become a hobbyist favorite. Cadsoft Eagle is a multi-platform freeware circuit layout program.
