Abstract
In a method of fixing a part on a main base, the method comprises the step of mechanically fixing the part on the main base by using solder. The main base preferably may be made of resin while the part preferably may be made of one where the solder enables to adhere to the part. The resin of the main base comprises, for example, a liquid-crystal polymer. The main base may comprise an optical base for use in an optical pickup. The part may comprise a leaf spring or a photodiode (PD) base to which a photodiode is adhered.
Claims21
A method of fixing a part on an optical base for use in an optical pickup, said optical base having a plurality of lands, said part comprising a photodiode (PD) base to which a photodiode is adhered, said method comprising the step of mechanically fixing said PD base on said optical base at said lands by using solder.
An optical pickup comprising:
- an optical base having a plurality of lands;
- a part mounted on said optical base, said part comprising a photodiode (PD) base to which a photodiode is adhered;
- and
- solder for mechanically fixing said PD base on said optical base at said lands.
An optical pickup comprising:
- an optical base having a plurality of lands;
- and
- a part mounted on said optical base, said part comprising a photodiode (PD) base to which a photodiode is adhered, said PD base being mechanically fixed on said optical base at said lands by solder.
