Panasonic RAE-0402 Laser Head For VCD
Knowledge of laser head installation
In order to prevent electromagnetic interference, the laser head is generally equipped with a protective solder joint (a large solder joint on the bald circuit board or on the flexible cable), which needs to be soldered with a soldering iron before the bald head is installed, otherwise the laser head will not be able to use normally. When the soldering iron reaches the temperature that can melt the tin, remember to unplug the power supply of the soldering iron, and then open the protective point of the laser head to prevent the static electricity of the ordinary soldering iron from burning the laser head, and at the same time, the protective tin point needs to be cleaned, so as not to affect the reading effect.
