pcb etching

Etching often seems to be something creative such as giving shape to a sculpture, or drawing a design on a glass. However, this is a process used to refine and sculpt printed circuit boards. Printed circuit boards are made of different materials as substrate, such as copper, FR4, plastic, aluminum, and so on. However, all

Even if you’ve never fabricated a PCB, you might be familiar with the process. PCB etching involves the application of UV-resistant laminate to a presensitized photoresist copper layer, which is then exposed to UV rays. Areas that are not covered will be etched off in a special etching solution. The PCB minimum etch technique has
