The Power to Imagine Series - High Performance Frame and Fill adhesives.

Frame-and-fill processes are used to protect highly complex areas on electronic circuit boards.

The process simply is as follows:

Step one, a highly viscous barrier – the so-called frame – is applied.

Step two, this area is quickly filled with a much lower viscosity filler material – the Fill.

With this precise process, areas on the circuit board can be protected from mechanical impact factors.  The combination of Frame and Fill materials allows the application of minimum barrier and potting heights and cures to a homogeneous coating.

Panacol’s new Frame and Fill adhesives are perfectly matched so that the frame and fill areas can be optimally dispensed without these adhesives flowing to undesired areas on the PCB.

The Frame material, Structalit® 5704, is a black, thermally curable single-component epoxy. This frame and glob top compound features excellent bead stability and high glass transition temperature of 150°C up to 190°C, depending on the curing parameters and the layer thicknesses. When using Structalit® 5704, no bleeding effects occur. Due to the very low ionic content of less than 20 ppm, Structalit® 5704 is also suitable for chip encapsulation on electronic circuit boards.

As a Fill material, Panacol has developed a range of adhesives with different rheological properties. The adhesives Structalit® 5717 to Structalit® 5721 are formulated with optimised flow behavior, so that the adhesives can be used on various chip and wire bonding geometries due to the differently adjusted viscosities.

Since the Fills have the same chemical base as the Frame material, the excellent physical and chemical properties of high glass transition range, ionic purity, temperature stability and minimal shrinkage behavior are also found in the fill materials.

Once cured, Structalit® 5704 and the matching fill of the Structalit® 5717-5721 series form a black, opaque and scratch-resistant coating. These properties together with a temperature resistance of up to 200°C ensure maximum reliability and stability into the future.
