Solder masking dots polyimide 12 mm 1000 pieces per roll - PPI 7012/1000

Where several small masks would be needed, a single large dot covers more cleanly. PPI TAP 7012 / 1000 masking dots are die-cut polyimide discs of 12 mm diameter on a roll, temperature resistant to 300 °C and therefore suited to the complete wave soldering process.

Benefits

• 12 mm diameter, the largest dot size of the series, for wide cut-outs and connector fields
• Temperature resistant up to 300 °C for wave and selective soldering
• Brown-transparent polyimide film keeps the masked area identifiable
• Total thickness of only 0.055 mm including adhesive, no disruptive build-up
• 1000 dots per roll, peeled off the liner individually

Applications

Covering wide cut-outs, connector fields and assembly openings before wave soldering, masking relay windows and contact areas during conformal coating, and protecting type plates while cleaning assemblies.

Compatibility and scope of delivery

Suitable for all common wave soldering, selective soldering and coating processes in electronics manufacturing. Delivery consists of one roll with 1000 masking dots of 12 mm diameter on a carrier liner.
