The aerosol can has been fit with a brush-type spray head to help the cleaning by
mechanical means. The aerosol can be used in an upside-down position (360° valve) for
hard to reach areas. As carbon dioxide is used as propellant it was possible to fill the
aerosol can with ±95% active product.
For minor cleaning operations it is possibly enough to rinse the printed circuit board with
KONTAKT PCC. Brushing of course supports the cleaning. To remove residues of flux, first
wet the brush and than spray the product on while brushing with a gentle pressure over
the printed circuit board. In doing so, hold the board as vertical as possible and work, from
top to bottom. For optimum results, it is best to re-rinse the surface with KONTAKT PCC.
If a “whitish deposit” forms on the printed circuit board after cleaning, this might mean
there was probably a coating present which has been partially dissolved by KONTAKT PCC.
In this case a perfect appearance is restored to the circuit board by coating it with our
conformal coating PLASTIK 70.
KONTAKT PCC has been tested for compatibility with PCB materials, solder-stop varnish
and electronic components. In particular it has been found that colour codings are not
damaged by KONTAKT PCC. There are only a few very sensitive plastics which are attacked
by KONTAKT PCC. These include, for example, polystyrene and polycarbonate.
Compatibility with such materials should be tested on forehand.
As KONTAKT PCC contain flammable solvents, all sources of ignition should be removed.
Do not spray on life equipment. A safety data sheet (MSDS) according to EU directive
91/155/EEC and amendments is available for all CRC products.
