Features: Golden plated R-4 gold-plated PCB, high-end atmosphere, high hardness, wear resistance, owning long using life span. Practical In addition to measuring the basic functions of millimeter and inch sizes, it also integrates relevant information for PCB design such as angle gauges, devices, IC pin spacing tables, Resistor and capacitor chip package, the commonly used diameter reference drill, line width size reference. We printed this information on FR-4 gold-plated PCBs. Versatile This versatile PCB ruler, it also integrates relevant information for PCB design such as angle gauges, devices, IC pin spacing tables, and more. Compact The PCB ruler is compact and lightweight, convenient to carry out, not occupying much storage space. Scope of application Electronic enthusiasts in the design process in urgent need of a measurement tool can be set all the necessary functions.
