Photochemical etching, also called photochemical machining or photo chemical machining, creates metal plates with microchannels, ports and manifolds. In PCHE manufacturing, these etched heat exchanger
A heat exchanger is a device that transfers thermal energy between streams at different temperatures. In most designs, a metal wall keeps the streams separate
Fuel cell stack design is not simply a matter of connecting more cells to achieve higher voltage. Engineers must balance cell count, active area, reactant
Chemical etching companies can look similar at first glance, but their actual capabilities often differ significantly in material range, thickness limits, tolerances, production scale, certifications
Photo etching uses photoresist, ultraviolet light, and controlled chemical removal to produce detailed parts from thin metal sheet. It is also called photochemical etching, photo
Physical etching removes material by directing energetic ions toward a surface. The ions transfer momentum to surface atoms and eject them from the material. This
Chemical etching and plasma etching usually solve different manufacturing problems. Chemical etching uses liquid etchants and photoresist to manufacture thin, flat metal parts. Plasma etching
Chemical etching is often the best option for thin, flat metal parts with complex features, tight spacing and burr-free edges. It uses chemical action instead
Photochemical etching is a precision manufacturing process that uses a photoresist stencil and controlled chemical dissolution to produce detailed components from metal sheet and foil.
