Direct Diode System Designed for OLED FRIT Welding and Soldering
Coherent Inc. offers the HighLight FAP 60/810 System, a fiber delivered, turnkey diode laser system that provides 60 Watts of output power at 810 nm. The HighLight FAP 60/810 is engineered to deliver exceptional reliability, convenience, and superior process uniformity for demanding, high throughput industrial applications, such as FRIT welding of OLED displays and other thermal processing tasks. In particular, the system offers excellent output characteristics, such as high power stability (power variations <±1%) and a fast, jitter-free risetime (<50 microsec). In addition, an optional four-lens imager enables variable magnification and a perfect, top hat irradiance profile at the work surface.
The HighLight FAP 60/810 also utilizes a unique, modular fiber delivery system that minimizes downtime and hence, cost of ownership in harsh industrial environments or with semi-skilled labor. Specifically, the 15 meter delivery fiber is attached to the laser source via standard connectors, meaning it can be quickly exchanged if it is damaged. System value is further enhanced by use of an integrated monitor that immediately shuts down the diode if it detects back-reflected light, minimizing the risk of diode damage. Plus HighLight FAP 60/810 brings proven reliability and long lifetime; the underlying fiber array package (FAP) technology uses Coherent grown AAA semiconductor material, with tens of thousands of FAP units in the field.
