Description:
This adaptable PCB ruler, it additionally coordinates applicable data for PCB structure, for example, angle gauges, devices, IC pin spacing tables, and the sky is the limit from there.

Electronic devotees in the planned procedure in critical need of an estimation apparatus can be set all the important capacities.

Notwithstanding estimating the essential elements of the millimeter and inch sizes, it additionally coordinates applicable data for PCB plan, for example, angle gauges, devices, IC pin spacing tables, Resistor, and capacitor chip package, the usually utilized distance across reference bore, line width estimate reference

We printed this data on FR-4 gold-plated PCBs.

R-4 gold-plated PCB, high-end atmosphere, high hardness, wear resistance.
