ACE-30510 SMD Adhesive with Thermal, Electrical Conductivity

Syringe packaging for ACE30510 SMD adhesiveFEATURES

  • A silver filled, fast curing, solvent-free, single component electroconductive adhesive with a high silver content for LED and die attach applications.
  • It has a pot life of 2 days and its rheology is well suited to application by microdispenser.
  • It exhibits an excellent thermal stability and a low humidity uptake : it is perfectly adapted for the lead-free solder reflow.
  • Its reactivity enables it to be cured at 150°C in less than 2 hours.
  • Its outstanding features are : high ionic purity, high thermal conductivity and good adhesion on current surfaces.

ADHESIVE PROPERTIES

PROTAVIC® ACE 30510 adhesive combines the excellent adhesive properties of epoxy resins with the good electrical and thermal conductivity of high level pure silver.  Its high silver content makes PROTAVIC® ACE 30510 perfectly adapted in the case where a high thermal conductivity is requested like die heat removal.  Its good latency enables it to be kept at 20 ± 2°C for 2 days,kept at 20 ± 2°C ————————————————————————————————————————————

for 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 temperature of between 150 and 200°C.  Its high thermal stability enables solder-free re-flow without lack of conductivity or adhesion.  Its fast-curing at 200°C without the formation of bubbles and its low expansion lead to fast attachments with a good reliability of the parts glued together.

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) Work on clean surfaces or clean all surfaces in order to remove any dirt or grease. Do not deposit 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 screen printing machine. Use polyester or stainless steel screen with a 80 to 325 mesh size (strands per inch)

4) Cure using one of the curing cycles which is compatible with the components, the substrate and the manufacturing conditions.  It is possible to cure in a tunnel furnace in 60 seconds with a 200°C flow temperature.
