Product Introduction:
PCB refers to a printed circuit board, which is the support of electronic components. Electronics enthusiasts urgently need a measurement tool in the design process to gather the commonly used and necessary functions. The multifunctional PCB ruler not only has basic functions such as measuring metric MM/English INCH dimensions, drawing lines, and measuring angles, but also integrates standard packaging for commonly used element mount components, line width size reference
