Bonding Processes for Processing Temperature-Sensitive Chips

Particularly when processing temperature-sensitive chips, bonding technologies which reduce material stress on the chip are inevitable. In such cases, bonding processes that enable a stable connection between chip and substrate without high temperatures and pressure are used. This manufacturing process can also be implemented inline using Tresky’s UV bonder.

UV Bonding is Often Used for Inline Processes and Temperature-Sensitive Components.

UV Bonding is a special bonding technology that uses ultraviolet (UV) light to cure or harden liquid adhesive. Unlike the use of epoxy, which requires different times and temperatures to cure depending on the type of adhesive, UV adhesive remains in its liquid state until it is exposed to high-energy UV radiation.

The UV adhesive is applied to the surface using a dispenser. The chip is then placed in the liquid adhesive by the bond head. The advantage of this technology is that the UV adhesive does not cure until the UV light source is applied. Because of that, the moment of curing can be precisely defined. Furthermore, the UV adhesive has a very short curing time or requires only a short activation to fix the component, with the final curing occurring afterwards.

UV bonding is frequently used in inline processes and for temperature-sensitive components.

Reduction of Material Stress

Due to low to non-existent thermal stress and low contact pressure, the UV DIE bonding process significantly reduces material stress during processing on the chip.

Flexibility

The respective curing times can be freely selected

Cycle Time Optimization

By using the UV light, curing of the adhesive can be carried out quickly and efficiently, even inline.
