Solder masking dots polyimide 4 mm 1000 pieces per roll - PPI 7004/1000

Wave soldering and coating both require selected openings and contact areas to stay free of solder and lacquer. The PPI TAP 7004 / 1000 masking dots are die-cut polyimide discs of 4 mm diameter on a carrier roll, applied by hand or from a dispenser, and their 300 °C temperature resistance carries them through the complete soldering process.

Benefits

• Temperature resistant up to 300 °C, suitable for wave and selective soldering
• 4 mm diameter for small pads, vias and single plated-through holes
• Brown-transparent polyimide film that keeps the masked area visible
• Total thickness of only 0.055 mm including adhesive for a flat fit without solder bridges at the edge
• 1000 dots per roll for consistent masking quality in series work

Technical data

Applications

Masking of solder pads, vias and test points before wave soldering, protecting contact areas and connector pins during conformal coating, and temporary fixing of small components in repair and prototype work.

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 4 mm diameter on a carrier liner.
