7. Operating and handling precautions
(1) This product has its life. The product life which is described in "4. Reliability" should be taken into account when using it.
(2) This product will be damaged by electrostatic discharge (ESD). Following precautions should be taken to avoid ESD damage.
⇒ Workers, workbenches and other equipment should always be grounded. Workers should always wear an antistatic wrist strap and an antistatic smock on them.
⇒ When handling this product, workers should always wear antistatic gloves or finger covers.
⇒ A stable DC power supply which is free from electrical transients should always be used when operating this product. A slow starter circuit should always be inserted between the power supply and this product in order to protect it from DC power surges.
⇒ Optical power output of this product should be set with a highly reliable and high quality variable resistance.
⇒ This product should always be connected to the driving circuit by soldering directly or through highly reliable connectors.
⇒ While this product is being operated, be sure to avoid touching the driving circuit or the terminals of this product with electrical probes from a synchroscope or a voltmeter.
⇒ An antistatic package should be used when storing this product.
⇒ This product should be processed in the rooms where relative humidity is kept at 50-70RH.
(3) Process products in clean rooms, and avoid touching with bare hands. Because laser beam is highly coherent, dust traces or fingerprints on the window glass are sufficient to interfere with
the passing beam, causing ripples in the far field pattern.
(4) A sufficient heat sink should be attached to this product when operating so that its case temperature is to be maintained at the same level as that of the surrounding.
(5) Even if the drive current supply has an automatic power control (APC), automatic current control (ACC), or both, be sure to monitor the optical power output with an optical power meter while setting it. Never estimate the optical power output only from the drive current because it is likely to be decreased by temperature rise of the surrounding.
(6) If the window glass of this product should become soiled, gently clean it with a cotton swab dipped in ethyl alcohol.
(7) Do not allow the heat sink to apply excessive pressure to the package cap. Because a window glass is as thin as 0.25mm.
(8) Although the beam emitted by this laser diodes is nearly invisible, it will be harmful to the human eyes. So the following precautions should be taken.
⇒ When this product is being operated, the emitting surface of a chip should not be viewed either directly or through a lens, microscope or optical fibers.
⇒ When operating this product, wear safety glasses.
⇒ To adjust the optical axis of this laser diode and peripheral devices, use an IR scope or a fluorescent screen that converts infrared light to visible light.
(9) When soldering this product, heat lead pins only using a soldering iron. Avoid heat the whole package using pre-heat or reflow soldering.
