ML-8150A
ML-8150A provides 5W of maximum power, which is upgraded more than twice compared with the conventional machine. It enables faster and deeper welding of even copper and gold, which have high reflectance to YAG fundamental laser and are hard to be welded.
Further, its beam becomes so thinner than the conventional one that deeper, thinner, and more beautiful welding can be achieved.
▶ Features
◆ Solid welding of cupper and gold by SHG green laser.
◆ Ø0.2mm fiber enabling high quality precision welding.
◆ High speed pulse control to shorten the takt time.(Pulse frequency is three times as high as the conventional model.)
◆ Two simultaneous energy share enabling two simultaneous processings and processing from two different angles.
◆ AMADA MIYACHI's original power feedback feature.
◆ Hybrid laser system combined with fundamental and SHG laser achieving deeper penetration.
◆ Easy-to-use jog dial.
▶ Real-time power feedback control
The laser output in the lamp-pumped module is monitored in real time. The monitored laser output is compared with the set waveform and power is fed back in real time, varying the energy input to the lamp to reproduce the set waveform and obtain the ideal laser output waveform.
▶ Variable mirrors
These mirrors eliminate laser power loss and improve branch balance.
▶ Waveform control
Equipped with a "fixed mode" that features three-level waveforms, and a "flex mode" to provide more complex waveforms..png "proimages/01_Laser_Welders/04_YAG_SHG_Green_Laser_Welder/ML-8150A/ML-8150A_JP (2).png")
▶ Power monitor
Laser energy (J) and average power (W) are monitored to detect abnormalities.
▶ External communications
Configuration of parameters and monitoring of performance can be carried out from a separate location.
- Type: RS-485 compliant, asynchronous, full duplex
- Data speed: 9600, 19200, 38400 bps
▶ Forced Air Cooling System
The air cooling system is available. No water and piping are necessary.
▶ Hybrid Laser Welding System
This system combines SHG green laser (ML-8150A) and the fundamental laser (ML-2000 series) at the focus unit to obtain improved welding depth and spot diameter.
▶ Why can green laser weld copper and gold?
SHG green laser is green-colored visible light with wavelength of 532nm, which is a half of fundamental laser (1064nm).
Absorption of green laser into copper and gold is 4.5 to 20 times higher than fundamental laser so that it is possible for green laser to weld copper and gold.
▶ Expand the Environmentally-friendly Method of Welding
Manufacturing by lead-free soldering and solder-less joining methods is recently required considering protection of the environment. Especially for electronic device manufacturing, their reliabilities have been a significant issue lately.
The Solution is... Laser Welding!
- ◆Heat-affected area can be reduced so that parts with weak heat resistance can be welded.
- ◆No flux is necessary.
- ◆No solder creeping.
- ◆Size and weight of parts can be minimized as solder is reduced.

By combining SHG green laser (ML-8150A) and fundamental laser (ML-2000 series) at the focus unit as illustrated at right, the welding depth and welding spot diameter are greatly improved comparing to that of a single laser.
▶ Applications
Welding of electronic devices, electric devices, IC leads, gold-plated patterns and more.
