Circuit Frame BEST11BCktTrackDF

Circuit Frame for Trace Repair-Dry Film Method

It has a 6 month minimum shelf life and is date-coded on the circuit frame.Tin plated with dry film attached. The base metal is 1 oz copper with chemical etchant which results in a high bond strength to the PCB. The coating on the PCB side is an immersion bright tin coating.The backing film is a low stress epoxy film adhesive with a Tg at 60C. This minimizes the thermal stress on bonded parts during thermal cycling or shock testing from 55 to 150C. It is a clear 1mil (0.0254mm) in thickness material which helps to make for an aesthetically pleasing repair. It has a 6 month minimum shelf life and is date-coded on the circuit frame.
