QUALITY ASSURANCE
After any processing of laser chip or laser diode TO-CAN (LD) by the customer, the performance, yield
and reliability 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 by
environmental 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. When attaching 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 TO-CAN (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
by incorporating 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 requiring high 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 technical
specifications, recommendations, and application notes relating to laser chip or laser diode TO-CAN
(LD) is believed to be reliable and accurate and is subject to change without notice. UOC reserves the
right to change its assembly, test, design, form, specification, control, or function without notice.
