High precision photo-etching / chemical machining

Photo Chemical Machining (PCM), or 'photo etching', is a subtractive process that selectively removes metal by chemical action. PCM is an extremely precise and cost-effective process that facilitates the production of a wide range of burr and stress free parts and tools in virtually any metal.


Virtually all metals are suitable for Tecan's Photo Chemical Machining (PCM) process. These metals are most widely used:
  • Stainless steel (300 series, 400 series, S526, S527 )
  • Nickel silver
  • Aluminuium
  • Kovar
  • Carbon steels
  • Mild steels
  • Molybdenum
  • Titanium
  • Lead
  • Silver
  • Nickel and nickel alloys
  • Copper
  • Invar
  • Brass
  • Beryllium
  • Phosphorous bronze
  • Invar copper
Tecan will investigate working with all other metals according to customers' specific requirements.


The diversity of precision metal parts and tools that can be produced by Tecan's Photo Chemical Machining (PCM) process is huge. However, here are some typical examples:

Aperture strips Instrument dials
Belts and bands Leadframes
Carrier plates Magnetic shielding
Circuit plates Metal stencils
Chopper wheels Microelectronic masks
Contacts Microwave components
Crystal masks Radar and RF antennas
Customer enclosures Reticles and graticules
Diaphragms RFI labyrinths
Disks RFI shielding
Electrical connectors Screens - all types
Electrodes Shadow masks
Electron gun and tube grids Shims
Encoder disks SMT stencils
Evaporation masks Springs
Filter elements Spring clips
Nozzles Strain gauges
Grids Surgical blades
Heat sinks Thermal switch components
Heater elements Vacuum masks
Hybrid lids Washers


Whatever can be drawn in profile and produced by CAD on an X/Y axis is suitable for the PCM process.

To follow is a guide to capability, but Tecan's R&D team will work with you to push these parameters if required.

Material thickness =(T): 0.01mm to 1.50mm
