Main features
  • Designed for Fingerprint Sensors
  • Low stress for ultra thin glass
  • Low outgassing and filler free

Product Description

LOCTITE ABLESTIK ABP 6892BA non-conductive die attach paste is designed for applications requiring low stress and robust mechanical properties. A package or device using this material will have a high resistance to delamination and popcorning after multiple exposures to Pb-free solder reflow temperatures. This material provides excellent adhesion to a variety of surfaces.

LOCTITE ABLESTIK ABP 6892BA is a transparent, low-temperature cure BMI acrylate without a filler. This, along with its low stress and low moisture absorption make it ideal for optical applications. It can be used both as a die attach paste but also for component assembly and fingerprint sensors, among other things.

Physical Properties
Viscosity
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow.

Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.

A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.

The viscosity of a material can be decreased with an increase in temperature in
order to better suit an application

Mechanical Properties
Tensile Modulus
Tensile Modulus
Tensile modulus is a mechanical property that measures the stiffness of an elastic material. It is the slope of stress / strain curve of a material under direct tensile loading.

It can be used to predict the elongation or elastic deformation of an object as long as the stress is less than the tensile strength of the material. Elastic deformation is caused by stretching the bonds between atoms and the deformation can be reversed when the load is removed.

Tensile modulus is affected by temperature and is an important engineering attribute since we generally want to keep elastic deformation as small as possible.
Tensile Modulus @150°C 16 N/mm2
Tensile Modulus @25°C 124 N/mm2
Thermal Properties
Glass Transition Temperature (Tg)
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.

The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
