Product Description

LOCTITE ABLEBOND 2030SC die attach adhesive has been formulated for use in high throughput die attach applications. This material is designed to minimise stress and resulting warpage between dissimilar surfaces. It can be used in a variety of package sizes and can be used for most metalic key substrates.

LOCTITE ABLEBOND 2030SC is a Snap curable adhesive with a proprietary hybrid chemistry that has various cure schedules and can cure very fast. One recommended cure schedule is 10 sec @ 150°C.

General Properties
Curing Schedule
Curing Schedule
Curing schedule is the time and temperature required for a mixed material to fully cure. While this applies to materials that cure with heat, there are also other materials that can be cured with UV.

Even though some materials can cure on ambient temperatures, others will require elevated temperature conditions to properly cure.

There are various curing schedules depending on the material type and application. For heat curing, the most common ones are Snap cure, Low temperature cure, Step cure and Staged cure.

Recommended cure type, schedule, time and temperature can always be found on the Technical data sheets.

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.
 24 hours
Physical Properties
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.

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

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 @-65°C 6,200 N/mm2
Tensile Modulus @150°C 350 N/mm2
Tensile Modulus @200°C 450 N/mm2
Tensile Modulus @25°C 3,300 N/mm2
Thermal Properties
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.

Additional Information

The TDS says to not re-freeze the material once its thawed out, and then its only lasts 24 hrs. Is there any way to extend this?

 

We do not recommend re-freezing. Partly because freezing down to -40°C takes a long time, and uses up a significant portion of the 24 hour worklife. And partly because condensation risks contaminating the sample with water. And partly because customers tend to lose track of the number of thaw/freeze cycles.

We generally suggest requesting the smallest syringe size/fill that is readily available and fits your process requirements.

However, if you restrict the refreeze to one time only (mark the syringe with a clear indicator), refreeze in a plastic zipper bag (to prevent later condensation), and freeze as rapidly as possible, it should be OK for initial evaluation. Do not exceed the 24 hours cumulative time at room temperature.

 

How should we handle the material at the tip of the syringe?

It is normal practice to “purge” the tip of the syringe before use. The sequence should be…

Try to keep the syringe vertical (tip down) throughout this process.

  • Thaw the syringe to room temperature (about 15 – 30 min, depending on syringe size)
  • Wipe away any condensation that has formed during the thawing.
  • Remove to top cap – this will remove any pressure from inside the syringe
  • Remove the tip cap
  • Replace the tip cap with a dispense needle
  • Fit the “receiver head” to the top of the syringe to supply pressure for dispensing
  • Dispense (purge) a stream of glue from the dispense needle, until you get a continuous un-broken column.  This indicates that the air has been removed from the tip, and you are “good to go”.
  • If you leave the syringe idle for more than a few mins, clean off any glue that has appeared on the dispense needle with a clean-room wipe, and repeat the purge.

If you are going to re-freeze the syringe, remove the dispense needle, and replace the tip cap.
