Stranco S-454 is a 1 mil gloss white polyimide thermal transfer film designed specifically for high-temperature lead-free solder applications and the corresponding high heat and harsh chemicals of circuit board and electronic component manufacturing processes. S-454 is appropriate for surface mount board processes, on either the top or bottom side of the board. It can also be used on the top side of the board in mixed processes, and is recommended for the bottom side which is directly exposed to the wave solder environment. 1 mil material is NOT recommended for auto print and apply applications.
