Laser Reballing Service

Retronix are the benchmark for an advanced and reliable laser reballing service.

This reballing system provides repeatable solder bumping technology for packaging optoelectronic devices, MEMS, sensors, BGA’s, CLCC’s, CSP’s, Flip Chips and many more. Solder ball reflow is performed by a laser system.

Retronix are the only company to offer Laser Reballing, mitigating the need for an additional reflow thus protecting the device. With the introduction of the latest laser technology this gives Retronix the ability to laser Leaded, lead free and high melt solder balls (HMP) down to 250 microns.

Retronix are the only company with approvals from high reliability industry leaders such as Leonardo Company, BAE Systems, Martin Baker Air Craft Company . Many more companies are realising the need to minimise the amount of reflows you give any single component therefore using a laser to perform the reballing is the only way to guarantee that there is no long term damage to the silicon.
