1) Cautions for mounting

(1) The temperature profile shows the temperature at the

soldering portion on the PC board surface.

(2) Depending on the mounting density condition, reflow

heating method, and PC board type (metal etc.), the relay’s

exterior and interior temperature may become extremely

high. Therefore, please confirm well under the actual use

condition before use.

2) The other cautions of reflow soldering

(1) When soldering condition is out of recommendation, the

relay performance may be adversely affected. If soldering

conditions are out of our recommendation, please inquire

our sales representative before operation.

(2) Please check the effect at the actual soldering because

heat stress to relay is changed by PC board type and

manufacturing process condition.

(3) Solder creepage, wettability or soldering strength will be

affected by the mounting condition or soldering material.

Please check the actual production condition in detail.

(4) Do not wash the relay as failures may occur.

(5) This product is not plastic sealed type. Please perform

coating with sufficient attention to avoid infiltration of the

solvent to the inside. Also, please pay careful attention

to use and store them with no contamination of foreign

material.
