What is Photo etching?

Photo chemical etching is a high-quality, fast turn-around, and economical manufacturing process for precision and detailed metal parts such as screens, shields, grids, washers RFI/EMI Shielding, Filters, Lead Frames, Encoder Disks, Buss Bar, Flat Springs, Heat Sinks, Drive Bands, Electrical Contacts, Ribbon Shields, Laminates, Backplates, EMP grids, Signage, Plaques.

Our Photo Chemical Etching Process

Our Photo Chemical Etching (PCE) process consists of several important steps.

Each step is a critical prerequisite to the next.
