What is Photo etching

What is Photo etching?

Photochemical Machining (PCM) is a high quality, fast turn-around, economical way of manufacturing precision, 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 Photochemical Etching Process

Our photochemical Etching (PCE) process consists of several important steps.
Each step is a critical prerequisite to the next.
