Head Module compatible with HD870 and SFHD62 / SFHD65 generation Key benefits Provides electrostatic protection at the solder joint to help prevent damage during handling and installation. Designed for reliable operation with compatible HD870 head systems and SFHD62 / SFHD65 generation units. Clear installation and handling guidance helps reduce the risk of damage to sensitive components, such as the objective lens and internal discs. How to use Before use, heat the silver tin protection solder joint with an antistatic soldering iron. Then unplug the connector and open the protection solder joint on the head. Ensure the head is completely disconnected prior to operation. Installation cautions The head must be fully disconnected; partial connection can cause the disc not to be read correctly in low light. Do not touch or drop the objective lens during installation. Do not adjust the potentiometer by yourself. Quality and safety All units in our only after passing factory testing. Quality control is strictly enforced to ensure reliability. Use scenarios Replacing or servicing the head module on HD870 systems in shops or manufacturing lines. Routine maintenance or upgrade tasks for SFHD62 and SFHD65 generation devices where proper ESD protection is essential. Field service or inhouse workshops requiring careful head installation with clear disconnection and handling procedures.
