525-2201-2 Circuit Frame
Circuit Frames provide a reliable method for replacing damaged surface mount pads, lands, and conductors on circuit boards. Featuring a dry-film adhesive backing, they bond quickly using heat from a Bonding Iron or Bonding System, eliminating the need for liquid epoxies. The resulting bond strength matches the original conductor and follows IPC-recommended repair procedures.
Trusted for more than 40 years, Circuit Frames are widely used by commercial, medical, and military manufacturers for high-reliability circuit board rework and repair applications. If you require a custom shape, submit a request using our Contact Us form.
