ACE-10131 Electronic Assembly Conductive Adhesive


A silver filled, fast curing, solvent free, single component electro-conductive adhesive.
It has a pot life of 48 hours and its rheology is well-suited to application by micro-dispenser and screen printing on automatic lines.  Its reactivity enables it to be cured on-line at 150-
200°C especially in the manufacture of tantalum capacitors. It outstanding features are : high ionic purity, good flexibility and good adhesion.  It is a more viscous, and latent version of the PROTAVIC® ACE 10110.  This new resin PROTAVIC® ACE 10131 is thus better designed for the micro-dispensing.


The PROTAVIC® ACE 10131 resin combines the excellent adhesive properties of epoxy resins with the good electrical conductivity of pure silver.  Its good latency enables it to be kept at 20°C for 1 to 2 ————————————————————————————————————————————

days, so the viscosity remains virtually unchanged throughout the working day.  It possesses excellent properties in terms of adhesion and protection against harmful environmental factors, due to its epoxy base.  It is 100 % cross-linkable by heat at temperatures of between 75 and 200°C.

filler-5x619METHOD OF USE

  1. Take the container out of the freezer not more than 20 to 30 minutes before use in order to prevent any re-absorption of moisture.
  2. Clean all surfaces in order to remove any dirt or grease. Do not put the adhesive on a substrate which has just been cleaned with chlorinated solvents.
  3. Apply the adhesive with :
  • a micro-dispenser. Use needles with an internal diameter of between 0.3 and 1.0 mm
  • a spatula
  • a screen printing machine. Use polyester or stainless steel screens with an 80 to
  • 325 mesh size (strands per inch)
  • a pad

4. Cure using one of the curing cycles which is compatible with the component, thesubstrate and the manufacturing conditions.

filler-5x619FIELDS OF USE

The PROTAVIC® ACE 10131 system’s excellent properties make it especially suitable for use in the microelectronics field.

  • Tantalum capacitors = sticking slabs onto lead frames
  • Surface mounting = mounting components on printed circuits. Screen printing  conductive circuits on flexible or semi-rigid substrates
  • Repairing printed circuits = adhesion which has to allow for differences in rates of  expansion between the two materials to be assembled
