PPI - solder masking for wave and reflow soldering
PPI supplies solder-masking products for electronics manufacturing: self-adhesive solder masking dots and high-temperature polyimide masking tapes (Kapton). They reliably protect contacts, gold pads, connectors and holes from solder and flux during both wave and reflow soldering.
The range spans round masking dots in diameters from 4 to 12 mm through to Kapton solder masking tapes in widths from 6 to 28 mm on 33 m rolls. The polyimide materials withstand temperatures up to 300 °C and peel off with low residue after the process.

Choosing the right solder masking
Dots or tape?
For individual round areas - such as contact pads or through-holes - masking dots are the fastest solution. For elongated or irregular areas, connector rows and edges, use Kapton masking tape, which can be cut to the length you need.
The right size
Dots are available in diameters from 4 to 12 mm - choose a diameter slightly larger than the area to protect. Tapes come in widths from 6 to 28 mm:
- narrow widths for single pins and fine contours
- wide tapes for connectors and larger zones
Temperature and removal
The polyimide materials (Kapton) are heat-resistant up to 300 °C, making them suitable for wave and reflow processes. After soldering, dots and tapes peel off again with low residue.

Frequently asked questions about PPI
What are PPI solder masking dots used for?
Solder masking dots are self-adhesive round masks that protect individual areas such as contact pads, gold pads or through-holes from solder and flux during wave and reflow soldering. They are peeled off again after the soldering process.
What temperatures do the materials withstand?
PPI masking dots and Kapton masking tapes are made of polyimide and are heat-resistant up to 300 °C. This makes them suitable for both wave soldering and reflow processes.
What is the difference between masking dots and masking tape?
Masking dots are pre-cut round masks for individual areas and holes. Kapton masking tape comes on a roll that can be cut to any length, making it ideal for elongated areas, edges and connectors.
In which sizes are the products available?
The masking dots are available in diameters from 4 to 12 mm, in packs of 1000 or 10000. The Kapton masking tapes come in widths from 6 to 28 mm on 33 m rolls.
Can the masking dots be removed with low residue?
Yes. The polyimide dots and tapes are designed to peel off again after soldering while leaving low residue, so the protected areas stay clean.
