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.
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.
