Broadcom recommends a 4-layer PCB with a dedicated ground plane, and thermal vias under the package to ensure efficient heat dissipation. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
Use a precision alignment tool or a fixture to ensure the optical axis of the encoder is perpendicular to the PCB. Apply a small amount of adhesive to secure the encoder in place during assembly.
Use a soft, dry brush or a lint-free cloth to gently remove any debris or contaminants from the optical components. Avoid using chemicals, ultrasonic cleaning, or high-pressure air, as they may damage the components.
Use ESD-safe materials, such as ESD-safe trays, bags, and wrist straps, to prevent electrostatic discharge damage. Ensure that all personnel handling the devices are grounded and follow proper ESD handling procedures.
Store the devices in their original packaging, away from direct sunlight, moisture, and extreme temperatures (above 40°C or below -20°C). Avoid exposing the devices to mechanical stress, vibration, or shock during shipping.
