Question:
If a MOSFET relay and PCB relay(SMD relay) will be mounted on a PCB by reflow soldering, can the same conditions as SMD relays be applied?
Answer:
The conditions are different from those for relays for PCB. Perform soldering based on the reflow soldering in the
Explanation
Reflow soldering conditions
The soldering conditions are as follows.
[ MOSFET relay ]
If the recommended conditions are exceeded, the performance of the semiconductor used may deteriorate due to heat.
Perform flow soldering within the recommended conditions.
- *1 We recommend that you check the result in your actual operating conditions before use.
- *2 Note that SSOP, USOP, VSON, S-VSON, and P-SON products, if ordered with (TR), will be delivered in a moisture-proof pack with taping packaging. If (TR) is not specified, cut tape products will be delivered in a pack without moisture prevention. If reflow soldering is to be applied to the products, please order them with (TR). Perform manual soldering when mounting the cut tape product. Cut tape products are packed without moisture prevention and are in a state of moisture absorption. If reflow soldering is performed, problems such as package cracking may occur due to heat stress.
[ SMD relay ]
- Since the temperature and time required for SMD relay soldering are lower than those for MOSFET relay soldering, check the solderability of both relays under SMD relay conditions.

Quick tips
Since the flow soldering is guaranteed only once, it is recommended to check the solderability before mass production.
