What is the heat-resistant temperature for a relay when manually soldering, and what are the precautions for manual soldering?
Please refer to Explanation about manual soladering for our relays.
- After smoothing the iron tip, solder according to the following conditions:
- Soldering iron: 30 to 60 W
- Iron tip temperature: 350°C
- Soldering time: Within about 3 seconds
- Use non-corrosive rosin for the flux because of the compatibility with the relay components.
Use an alcohol solvent with less chemical action for flux.
- When soldering the terminals, make sure that no solder, flux, or solvent adheres to any part other than the terminals. If solder, flux, and/or solvent enters the inside, it could cause insulation degradation and poor contact.
For more information, see Safty Precautions for All Relays: 6-10 Automatic Mounting of Relays for PCBs.
Note that, as shown in the figure below, some solders have a cut surface to prevent flux from scattering.
