Product catalog summary
Overview: Tech-Etch specializes in precision-engineered parts using photoetching, laser cutting, forming, and finishing processes. Their products include thin metal parts, flexible circuits, and EMI shielding gaskets.
Photoetching: This process produces intricate metal components with close tolerances using materials like copper alloys, stainless steels, aluminum, titanium, and molybdenum. It is suitable for encoders, masks, and filters.
Materials and Tolerances: Metals can be etched from .0005" thickness, with minimum feature sizes for holes or slots being 1.1 times the material thickness. Tolerances for dimensions are specified in tables.
Forming: Combining photoetching with tooling produces burr-free parts. Hand forming is used for sharp internal radii, and heat treatment enhances material properties.
Special Processes: Includes laminating and etching polyimide film, precision spot welding, and finishing techniques like plating and electropolishing.
Laser Cutting: A 2.5 KW CO2 pulse laser is used for precise cutting, ideal for prototypes and thicker materials.
Board Level Shielding: Offers custom and standard designs with no tooling charges, allowing design flexibility and quick prototyping.
Flexible Circuit Manufacturing: Produces high-reliability circuits using adhesive-based and adhesiveless materials, with capabilities like plated through vias and SMT assembly.
MicroEtch® Screens: These burr-free screens offer higher tolerance hole sizes than woven wire mesh, suitable for frequent cleaning applications.
Facilities and Certifications: Tech-Etch operates a large facility in Massachusetts, adhering to ISO 9001:2008 and AS9100:2009 Rev C standards.
Special Products & Capabilities:
EMI/RFI Shielding: Offers a range of standard and custom EMI/RFI shielding products, including beryllium copper and wire mesh gaskets, conductive elastomers, and metalized fabric over foam.
Flexible Circuits: Manufactures flexible circuits for Medical, Aerospace, and Telecommunications sectors, featuring adhesiveless construction and comprehensive assembly services.
Medical Components: Capable of etching corrosion-resistant materials like Titanium, Tungsten, and Nitinol for medical tools and implants.

Tech-Etch manufactures formed parts by combining photoetching, used for blanking, with inexpensive or universal tooling, used for forming. Select the etch and form manufacturing process for quick turn and low tooling cost. This method produces burr-free parts in intricate and complex designs and shapes. It also makes it possible to prove your design in preproduction quantities without having to commit to expensive, progressive die tooling. The following guidelines show practical methods to assure proper function and the best cost. HAND FORMING For bends that do not require structural strength...

SPECIAL PROCESSES LAMINATING & ETCHING POLYIMIDE FILM When a dielectric is required to maintain accurate finger spacing or for insulation, Tech-Etch can laminate materials such as polyimide. Polyimide can be die-cut and directly bonded in place or full sheet laminated and then photoetched for extremely accurate positioning. Parts can be formed after lamination of insulation. ASSEMBLY Tech-Etch's precision spot welding equipment is used to join small parts as well as accurately close cylinders and boxes. Soldering is an alternative. Various adhesives are also applied to join assembled components...
