7 / 41 page  7 PCB Assembly Considerations 1. Insert the sensor and all other electrical components into PCB. 2. Insert the LED into the assembly clip and bend the leads 90 degrees. 3. Insert the LED clip assembly into PCB. 4. Wave solder the entire assembly in a no-wash solder process utilizing 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 the lead shoulders do not normally rest 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. 5. Place the lens onto the base plate. 6. Remove the protective kapton tape from optical aperture of the sensor. Care must be taken to keep contaminants from entering the aperture. Recommend not to place the PCB facing up during the entire mouse assembly process. Recommend to hold the PCB first vertically for the kapton removal process. 7. Insert PCB assembly over the lens onto the base plate aligning post to retain PCB assembly. The sensor aperture ring should self-align to the lens. 8. The optical position reference for the PCB is set by the base plate and lens. Note that the PCB motion due to button presses must be minimized to maintain optical alignment. 9. Install mouse top case.There MUST be a feature in the top case to press down onto the PCB assembly to ensure all components are interlocked to correct vertical height. Figure 6.

Assumption: Base plate construction as per the Avago Technologies supplied IGES file and HDNS-2100/2100#001 lens. Typical Distance HDNS-2100 round lens HDNS-2100#001 trim lens Creepage (mm) 40.5 17.9 Clearance (mm) 32.6 9.2 Note that the lens material is polycarbonate and therefore, cyanoacrylate based adhesives or other adhesives that may damage the lens should NOT be used. |
