Small area lamp boosts high speed adhesive curing

DELO Industrial Adhesives has developed a curing lamp with a higher peak intensity with improved homogeneity for LED packages and automotive packages.

The Delolux 30 is the replacement for the Delolux 80 series of curing lamps with a higher peak intensity of up to 22.5 W/cm² as well as increased homogeneity in its intensity distribution. This enables quicker curing of adhesives and a more consistent final bond, increasing production efficiency and yield, as well as product quality.

The lamp is available in wavelengths of 365, 400 and 460 nm, each of them offered in one of two configurations. The first is in an all-in-one package which includes other necessary equipment, including integrated water-cooling and a control unit. The second is one individual lamp head that can be integrated into new or existing production lines.

The cylindrical lamp head measures at 80 mm tall with a diameter of 30 mm, connecting with a highly flexible 450 mm-long flat-ribbon cable.

This allows the lamp head can be positioned to irradiate light from above the lens for LED packaging. The higher peak intensity reduces exposure time and improves yields. In the automotive sector, the lamp can also be used in chip encapsulation processes.

The adhesive curing lamp can also be used with other DELO process technologies such as activation on the Flow to streamline the lidding process in the potting process. This combines adhesive dispensing and pre-activation in a single process step. This is particularly suitable for bonding and encapsulating temperature-sensitive electronic components as an alternative to existing bonding processes. With activation on the flow the adhesive is already irradiated during the dispensing process, which starts the curing reaction even before the adhesive meets the component. After the combined process step, the components can be joined.

The exposed adhesive areas can also be irradiated and fixed after joining. This provides immediate initial strength, preventing the adhesive from flowing out and the components from slipping, which allows them to be further processed right away. The adhesive cures reliably to final strength without any additional process step, even in undercuts and shadowed areas.

DELO has developed epoxy resin adhesives specifically for activation with two different initiators that react to different wavelengths and initiate curing. This dual-initiator system makes the optional light fixation step possible with the light head.
