In the production of mobile phones, the laser is used in many ways. Pulsed lasers trim the deep-drawn housing on a 3D laser processing system and cut keypad holes and penetrations. Housing parts in the interior and lithium ion batteries are precision-welded by pulsed lasers. Nearly all keypads are marked with lasers. Frequently, the plastic cover that protects the display is fastened to the shell of the phone by a laser.

Using the unique Power Regulated Burst, TruPulse lasers weld electrical contacts on switches more than three times faster than comparable pulsed lasers, for example. To do this, TruPulse lasers can increase their average power briefly, using the workpiece transfer time to recharge their stored energy. The result is a shortened welding time and a shorter overall processing cycle.

TRUMPF lasers mark electronic boards, relays, ICs, motor circuit breakers, mobile phone keypads, silicon wafers and much, much more – around the clock. Your advantages:

• Product labeling in a very small space, allowing product traceability
• Fast and custom marking of multiple parts in one pass
• Online integration of fabrication data from a higher-level production system
• No mechanical or thermal load during marking, gentle handling for sensitive electronics
