Product Description

LOCTITE ECCOBOND FIL 7010C is a low viscosity, one component, SVHC free, epoxy product designed for use as a potting or encapsulation resin protection for stress sensitive electronic components. It is specially formulated with a low thermal expansion and high Tg, along with a toughened polymer backbone making it ideally suited to survive severe thermal shock conditions with a high resistance to micro cracking.

LOCTITE ECCOBOND FIL 7010C is a REACH compliant product, designed to survive constant service temperatures of 150°C, with peak temperatures of up to 180°C for chip on board encapsulation.

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	180 days

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

Volume Resistivity

Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.

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.	16 ppm/°C
Coefficient of Thermal Expansion (CTE), α2 Coefficient of Thermal Expansion (CTE), α2 CTE α2 (alpha 2) is the slope of the Coefficient of thermal expansion in a temperature range above the Glass transition temperature (Tg). It explains the extent to which a material will expand after it passes Tg.	58 ppm/°C

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.

160 °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.

0.72 W/m.K

Additional Information

Directions for use

Cure the product per the cure schedule mentioned in the Typical Cure Schedule section of the document.
The surfaces on which the adhesive has to be applied should be clean, dry and free from all dust.
Initially dispense LOCTITE ECCOBOND FIL 7010C on the outline of the glob referred to as the "dam".
The dam is then filled in with LOCTITE ECCOBOND FIL 7010C material.
Both materials can be co-cured after dispense.

For the low stress schedule we need to point out that according to the DSC curve the cure reaction barely starts at 100-125C. Yes, it happens and yes it is a low stress alternative but given the oven temperature tolerances, batch to batch variations etc we always run the risk of inconsistent results. You should always develop a process that works for your application but for repeatable and predictable results we recommend curing at least at 140°C.
