Product Description

LOCTITE ABLESTIK ABP 8068TA is a semi-sintering die attach adhesive designed for semiconductor packages requiring high thermal and electrical conductivity. This material’s epoxy assisted sintering formulation is designed to provide high adhesion, high thermal and low stress properties which are essential for thermal and reliability performances of high end power packages. .

The thermal performance of LOCTITE ABLESTIK ABP 8068TA is comparable to a solder paste material. In conventional box oven curing, it will cure at 1 hour at 200ºC or 175ºC.

Technical Specifications

General Properties

Shelf Life Shelf Life Shelf life is the amount of time after manufacturing that a product is guaranteed to retain its properties. It differs vastly per product and it is based on temperature and storage conditions. The properties can be guaranteed for the temperature and time range indicated on the TDS since those are the ones tested to be the best for the product.
Shelf Life @ -40°C	365 days

Work life @25°C

Work life @25°C
Work life is the amount of time we have to work with a material until it is no longer able to be easily worked and applied on a substrate.

It is based on the change in viscosity and it can rely on the application requirements.

Moisture Absorption

Moisture Absorption
Moisture absorption shows the capacity of a polymer to absorb moisture from its environment.

Absorbed moisture can reduce the glass transition temperature and strength of a polymer and can also result in popcorning, unreliable adhesion or voids in the bond line due to moisture desorption or entrapment.

Moisture absorption should always be mentioned with the test conditions to provide a meaningful frame of reference.

Mechanical 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
Viscosity	9,000 MPa.s
Thixotropic index Thixotropic index Thixotropic Index is a ratio of a material s viscosity at two different speeds in Ambient temperature, generally different by a factor of ten. A thixotropic material s viscosity will decrease as agitation or pressure is increased. It indicates the capability of a material to hold its shape. Mayonnaise is a great example of this. It holds its shape very well, but when a shear stress is applied, the material easily spreads. It helps in choosing a material in accordance to the application, dispense method and viscosity of a material.	6

Die Shear Strength Die Shear Strength Die Shear Strength is the force that has to be applied to the side of the semiconductor die before it shears from its mounting. Shear strength is measured for various die sizes, substrates and operating temperatures so check the Technical data sheet for your intended usage.
2x2mm @260°C	7.3 kgf
3x3mm @260°C	13.1 kg-f

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 @25°C	11,800 N/mm2
Tensile Modulus @150°C	2,100 N/mm2
Tensile Modulus @250°C	1,500 N/mm2
Tensile Modulus @-65°C	15,800 N/mm2

Thermal Properties

Coefficient of Thermal Expansion (CTE)

Coefficient of Thermal Expansion (CTE)
CTE (Coefficient of thermal expansion) is a material property that is indicative of the extent to which a material expands with a change in temperature. This can be a change in length, area or volume, depending on the material.

Knowing the CTE of the layers is helpful in analyzing stresses that might occur when a
system consists of an adhesive plus some other solid component.

Coefficient of Thermal Expansion (CTE), α1

Coefficient of Thermal Expansion (CTE), α1
CTE α1 (alpha 1) is the slope of the Coefficient of thermal expansion in a temperature range below the Glass transition temperature (Tg).

It explains how much a material will expand until it reaches Tg.

54 ppm/°C

Thermal Conductivity

Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance.

Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.

110 W/m.K
