Product Description

LOCTITE ABLESTIK CE 3104WXL is an electrically conductive epoxy adhesive that is a Pb-free alternative to solder. It is a silver filled epoxy that can be heat cured in low temperatures and is typically used for SMD component attach on Sn, Sn/Pb and OSP coated Cu substrates.

LOCTITE ABLESTIK CE 3104WXL uses a unique blend of fillers with tightly controlled particle sizes to provide ultra-fine pitch resolution (<500µm) when printed using either a stainless steel mesh screen or a metal mask stencil. The lower surface tension versus solder means no bridging on fine-pitch assembly patterns.

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.
72 hours
Mechanical Properties
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 65,000 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.

Additional Information

In the following image you can see that the CE 3104WXL stencil printing results with 25um stencil showing that 80-100um dot diameter with 100um spacing (or 200um pitch) look good, but smaller dots and pitch are getting tricky.

The results are color coded so 100um spacing exhibits proper printing with larger dot diameters.
