Figure 4—Recommended Mounting
*
1. IR and vapor phase reflow are recommended.
2. Avoid the use of cleaning agents that attack epoxy resins, which form part of the
resistor construction.
3. Vacuum pick up is recommended for handling.
4. If the use of a soldering iron becomes necessary, precautionary measures should be
taken to avoid any possible damage/overheating of the resistor.
* Recommendation: The solder fillet profile should be such as to avoid running over the
top metallization.
