  • DIY Safe and High-Resolution Photoresist Dry Film Using Benzophenone and PVA

    Photoresist dry film is a crucial component in the fabrication of printed circuit boards (PCBs). The process involves applying a thin layer of photoresist on top of a copper-clad board and exposing it to ultraviolet (UV) light through a photomask, which selectively hardens the photoresist in certain areas. The unhardened photoresist is then washed away, […]
