Application Of UV Laser Marking Machine In Surface Etching / Circuit Production

Ultraviolet laser marking machine works quickly when applied to the production of circuits, and can etch surface patterns on circuit boards in minutes. This makes UV lasers a fast method for producing PCB samples. R & D noted that more and more sample laboratories are being equipped with internal UV laser systems. Depending on the optical instrument verification, the size of the UV laser beam can reach 10-20 μm, thereby producing flexible circuit traces. The biggest advantage of ultraviolet rays in the production of circuit traces is that the circuit traces are extremely tiny and need to be seen under a microscope. This board measures 0.75 "x 0.5" and consists of a sintered ceramic substrate and tungsten / nickel / copper / surface. The laser is capable of generating 2 mils of circuit traces with a pitch of 1 mil, resulting in a total pitch of only 3 mils. Although using laser beams to produce circuits is a faster method for PCB samples, large-scale surface etching applications are left to the chemical process.
