Benzophenone and PVA based low-cost, safe and high-resolution photoresist for PCB fabrication.
For low-volume and low-cost fabrication of printed circuit boards (PCBs) in a prototyping lab or in an MSME setting, PVA and benzophenone based low cost photoresists could be of high benefit for rapid fabrication and testing of the components. The main components of the negative type photoresist are Benzophenone and Poly Vinyl Acetate (PVA), generally…
