P.C. Flex Mask is a solder resist mask made of latex rubber without solvent additives used for the protection of contacts, switches, connectors, plated-through holes and bare places on PCBs during the soldering process. It is also suitable for protecting electronic components against the contact with fluxes and cleaning agents. Afterwards, the mask can be easily peeled off and leaves no residues.

Protective lacquers are special lacquers developed to protect PCBs and the associated equipment against environmental influences. They protect wirings against chemicals, vibrations, humidity, wetness and high temperatures that could cause corrosion, mold formation and current leakage leading to a failure in case of an uncoated PCB.
Protective lacquers improve the reliability and safety of PCBs and offer a life-time efficiency by creating a protective film that insulates the PCB protecting it against enviromental influences like chemicals, humidity and other pollutants.
Protective lacquers facilitate a higher current and a shorter distance between the traces as they prevent current leakage.
Information on the application
Cleaning
PCBs have to be cleaned thoroughly before coating so that a maximum of adhesion can be reached. Flux residues have to be removed to prevent corrosion.
Environmental regulations
To use at min. 16°C or a relative humidity of 75%. As all PCBs absorb humidity, it has to be removed before coating so that the protective lacquer can completely develop his characteristics. Pre- and vacuum-drying are ideal for his purpose.
Film thickness
Depends on the application method.
Brushing or spraying
Mix the diluted lacquer well and let it rest for about 2 hours before spraying or brushing. Brush at room temperature with a natural fiber brush.
Dip coating
Dip the assemblies vertically. Dwell time approx. 1 minute. Pull them out slowly so that an even film is formed. For draining hang it over the tank.
Drying
Most of the protective lacquers have different drying times.
For further information see the technical data sheet.
