PCB means printed circuit board, It is the support of electronic components, Electronic enthusiasts need a measuring tool which can be a collection of all necessary functions in the design process. This Multi-Fonction PCB Ruler is producted by ALSRobot, In addition to measuring millimeter and inch size, It also integrates related information of PCB design, Such as protractor, device, IC lead pitch comparison table, resistance and capacitance SMD package, common reference hole diameter, width size reference. We printed all these info on gold-plated PCB FR-4.
