Description:
This versatile PCB scale also integrates information about PCB design, such as angle meters, devices, and IC pin pitch tables.
Electronic enthusiasts urgently need a measurement tool in the design process to set all the necessary functions.
In addition to the basic functions of measuring millimeters and inches, it also integrates information about PCB design, such as angle meters, devices, IC pin pitch tables, resistor and capacitor chip packages, common diameter reference drills, line width size references.
We printed this information on the FR-4 gold-plated PCB.
R-4 gold-plated PCB, high-end atmosphere, high hardness, good wear resistance
