Description of the machine integrated laser components:

Diode laser + Soldering Process Controller:
The LASCON® Controlled Laser LCL is a kind of hybrid between a diode laser with typical power of 140W ( optional 60W or 100W ) and integrated unique LASCON process controller – all in one box.

Laser heads and laser control unit:
At the end of the optical fiber is a laser processing head. There, a pyrometer and a video camera are projected into the beam path of the laser. The pyrometer measures 10,000 times per second the temperature in the laser focus. The unique LASCON controller compares measured temperature with aprogrammed temperature curve and does closed loop control to the laser power. The system stores up to 500,000 laser processes and monitors all processes in real time based on pre-defined parameters. The parameters can be programmed with a simple programming language in a process script. The LASCON controller can store up to 255 scripts and activate within milliseconds. If the laser process differs from the programmed parameters, theLASCON controller generates an error control signal that can be interpreted by a PLC.

Precision Solder Wire Feeder with Encoder Feedback:
The solder wire feeder SWF100 was developed especially for fast and precise soldering. It has afeeding accuracy of 10μm and a response time of under 1ms. The feeding head is gearless andhas a very long lifetime. As special feature, even the forward feeding accelaration is programmable.This leads to an improved start behaviour of the soldering process by a slowdown of the feeding atthe beginning. At first, a solder melt pool is formed in which the wire is pushed then with constant speed.

Features:

• Controller unit fully integrated into LCL – see above
• Zero slip feeding by encoder
• Integrated encoder detects also solder wirehold-up and the end of the solder wire
• Complete feeding process programmable in LASCON® Process Manager by scriptcommands
• Power supply provided by LCL
• Precision adjustment device for positioning the nozzle
• Standard solder wire diameter is 0.3mm and 0.5mm ( others in request )
• Patent pending „Wire Checker Technology“ allways detects the position of the tip of thesolder wire before starting the laser soldering process

• Laser soldering
