CER 110 HV TEMPORARY SOLDER MASK
(Water Soluble)
Description:
CER 110 HV is a water soluble liquid polymer. The printed circuit board fabricator/electronic assembler uses this temporary aqueous mask for production screen-printing and semi-automatic press applications. The CER 110 HV is a state of the art system without any metals or clay fillers leaving circuit boards completely free of any residues after the wash cycle and minimizing poisoning of closed-loop systems.
Applications:
CER 110 HV solder mask prevents filling of through-holes on printed circuit boards so that components or fasteners can be inserted after wave-soldering. It is also used to mask edge connector fingers or other keep-out areas.
Unique Benefits:
 | •Non-corrosive to copper, gold and silver |
| •No metals or clay fillers |
| •Nonflammable |
| •0zone safe, CFC/HCFC free |

Directions:
Screen Printing Applications:
CER 110 HV temporary mask is designed for screen printing utilizing a polyester monofilament mesh of 60-90 (or equivalent). For best printing utilize a 60-65 durometer squeegee with a rounded print edge. A waterproof - resistant film or emulsion should be used for screen images.
A coating thickness of 10 mil is recommended for circuit trace surfaces. For hole filling, squeegee the 110 HV at least half the depth of the barrel. Note: 110 HV must be completely dry inside the hole before passing through the solder wave.
If heavier than normal surfaces are required, print gold surfaces twice, drying in between. A coating thickness up to 20 mil (maximum) is acceptable.
Process Note: Keep the quantity in the screen to a minimum. Keep a second container available for used material since adding back to the original container can significantly alter viscosity.
Semi-Automatic Press Application Data:
110 HV mask can also be applied with semi-automatic presses such as a Clamshell or Four Poster utilizing a polyester monofilament of 40-80 mesh in conjunction with a waterproof stencil.
Note: 110 HV mask can be left on assemblies for extended periods of time.
110 HV can be thinned with water and/or alcohol to adjust viscosity. However, thinning reduces thixotropy.
Drying and Curing:
Drying time varies according to the thickness of the 110 HV mask film laid down, as well as atmospheric conditions (humidity).
For air curing, approximately 30-60 minutes at 70 degrees F. with circulated air and 40 to 45% relative humidity is recommended for a 10 mil coating.
To accelerate drying time:
1 ) use a forced air oven for 15-30 minutes at 140 degrees F to150 degrees F. or
2) use a forced air oven for 3-4 minutes maximum at 300 degrees F .
Note: Boards can be stacked when dry, but not print surface to print surface. If boards are to be stored or shipped in plastic wrap, keep the ends open. High humidity will prolong drying time.
Cleaning:
CER 110 HV is an air dry water-based product. Clean up tools and equipment immediately.
CER 110 HV is quickly removed in batch cleaning and in-line water systems with warm water. Dispose of washings in accordance with Federal and State regulations.
Safety: See MSDS.
