Overview and Specifications:

If you solder surface mount components for the first time, you might be surprised: "How small these patch devices are!" They also have many different names! QFN, TDFN, SOIC, SOP, J-Lead, what do these things mean, and how can you tell them how big? Now you can have a board that you can use as a reference. This is a handy, stylish PCB reference ruler. Measuring approximately 25.4mm x 152.4mm, this standard thickness is FR4, and the gold-plated ruler is engraved with the most common component packages often encountered. It also has a font size description, a trace width chart, and a set of American Wire Gauge (AWG) drill sizes so you can measure the thickness of your traces at work.
