Data Sheet

The Avago Technologies ADNS-6530 integrated Chipcon-board COB LaserStream sensor along with the ADNS-6150 SFF lens form a complete and compact laser mouse tracking system. It is the laser-illuminated small form factor SFF navigation system. Targeted at cordless applications. The chip integrates the sensor and VCSEL into a single package, providing a small form factor. This new opto-mechanical architecture allows for more compact and cost-effective mouse designs. Powered by latest Avago Technologies LaserStreamTM engine, the mouse can track on more than traditional LED-based optical navigation, especially on glossy and reflective ones. In addition, the high-performance, low power architecture is capable of sensing high-speed mouse motion while prolonging battery life-two performance areas essential in demanding cordless applications.

There is no moving part in the complete assembly for ADNS-6530 laser mouse system, thus it is high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly.

Theory of Operation

The ADNS-6530 integrated COB LaserStream sensor comprises of sensor and VCSEL in a single package.

The advanced class of VCSEL was engineered by Avago Technologies to provide a laser diode with a single longitudinal and a single transverse mode. In contrast to most oxide-based single-mode VCSEL, this class of Avago Technologies VCSEL remains within single mode operation over a wide range of output power. It has significantly lower power consumption than a LED. It is an excellent choice for optical navigation applications.

The sensor is based on LaserStream technology, which measures changes in position by optically acquiring sequential surface images frames and mathematically determining the direction and magnitude of movement. It contains an Image Acquisition System IAS , a Digital Signal Processor DSP , and a four wire serial port. The IAS acquires microscopic surface images via the lens and illumination system. These images are processed by the DSP to determine the direction and distance of motion. The DSP calculates the and relative displacement values. An external microcontroller reads the and information from the sensor serial port. The microcontroller then translates the data into PS2, USB, or RF signals before sending them to the host PC or game console.

Figure 2D Assembly Drawing of ADNS-6530, PCBs and Base Plate

Figure Exploded view drawing Shown with ADNS-6530 integrated COB LaserStream sensor and ADNS-6150 SFF lens, the components self-align as they are mounted onto defined features on the base plate. The ADNS-6530 integrated COB LaserStream sensor is designed for mounting on a through-hole PCB, looking down. There are an aperture stop and guide holes on the package that align to the ADNS-6150 SFF lens. The VCSEL is used for illumination, provides a laser diode with a single longitudinal and a single transverse mode. It is particularly suited as lower power consumption and highly coherent replacement of LEDs. It also provides wider operation range while still remaining within single-mode, reliable operating conditions. The ADNS-6150 SFF lens is designed for use with ADNS-6530 integrated COB LaserStream sensor. The VCSEL contained in the package and the lens provides the directed illumination and optical imaging necessary for proper operation of the sensor. ADNS-6150 SFF lens is precision molded optical components and should be handled with care to avoid scratching of the optical surfaces. Avago Technologies provides a STEP or IGES file drawing describing the base plate molding features for lens and PCB alignment.

Assembly Recommendation

Insert the integrated COB LaserStream sensor and all other electrical components into the application PCB.

Wave-solder the entire assembly in a no-wash solder process utilizing a solder fixture. The solder fixture is needed to protect the sensor during the solder process. It also sets the correct sensor-to-PCB distance, as there is no stopper feature on the lead to rest the package on the PCB surface. The fixture should be designed to expose the sensor leads to solder while shielding the optical aperture from direct solder contact.

Place the lens onto the base plate. Care must be taken to avoid contamination on the optical surfaces.

Remove the protective kapton tapes from the optical apertures of the sensor and VCSEL respectively. Care must be taken to keep contaminants from entering the apertures.

Insert the PCB assembly over the lens onto the base plate. The sensor package should self-align to the lens. The optical position reference for the PCB is set by the base plate and lens. The alignment guide post of the lens locks the lens and integrated COB LaserStream sensor together. Note that the PCB motion due to button presses must be minimized to maintain optical alignment.

Optional The lens can be permanently locked to the sensor package by melting the lens’ guide posts over the sensor with heat staking process.

Tune the laser output power from the VCSEL to meet the Eye Safe Class I Standard as detailed in the LASER Power Adjustment Procedure.
