<p>The first time you soldered up a surface mount component you may have been surprised "these are really small parts!" and there's dozens of different names too! QFN, TDFN, SOIC, SOP, J-Lead, what do they mean and how can you tell how big they are? Now you can have a reference board at your fingertips, with this snazzy PCB reference ruler.<br /><br />Measuring approx 1" x 6", this standard-thickness FR4, gold plate ruler has the most common component packages you'll encounter. It also has font size guide, trace-width diagram, and a set of AWG-sized drills so you can gauge your wire thicknesses.</p><p>New! As of Sept 15, 2014 we're now shipping v2 which is basically the same thing as the original but Inches are marked with 1/10 " rather than the more common 1/8". The centimeter side is still 0.1cm marks.</p><p>Â </p><p><br /></p><p>Â </p>
