U-SMD-802 SERIES 5630 LASER DIODE■ PrecautionsQUALITY ASSURANCE
After any processing of laser chip or laser diode SMD (LD) by the customer, the performance, yield andreliability of the product, in which the chip or LD is applied, are subject to change due to customer’s
handling, assembly, testing, and processing. Because laser chip and LD are strongly affected byenvironmental conditions, physical stress, and chemical stresses imposed by customer that are not in Union
Optronics Corp. (UOC) control and hence no guarantee on the characteristics and the reliability at all after
the shipment. Also, UOC does not have any responsibility for field failures in a customer product. Whenattaching a heat sink to laser chip or LD, be careful not to apply excessive force to the device in the process.
SAFETY PRECAUTIONS
Although Union Optronics Corp. (UOC) keeps improving quality and reliability of its laser chip and laser
diode SMD (LD), semiconductor devices in general can malfunction or fail due to their intrinsic
characteristics. Hence, it is required that the customer’s products are designed with full regard to safety byincorporating the redundancy, fire prevention, error prevention so that any problems or error with UOC laser
chip or LD does not cause any accidents resulting in injury, death, fire, property damage, economic damage,or environmental damage. In case customer wants to use UOC laser chip or LD in the systems requiringhigh safety, customer is requested to confirm safety of entire systems with customer’s own testing.
SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE.
The information provided by Union Optronics Corp. (UOC), including but not limited to technicalspecifications, recommendations, and application notes relating to laser chip or laser diode SMD (LD) isbelieved to be reliable and accurate and is subject to change without notice. UOC reserves the right tochange its assembly, test, design, form, specification, control, or function without notice.
