CHAPTER 3 SOLDERING CONDITIONS


3.3 Recommended Soldering Conditions
3.3.3 Recommended temperature profile for each soldering method

NEC Electronic's recommended soldering conditions can be broadly classified into heating conditions of soldering method, package moisture absorption control, and number of times the product is to be mounted.

NEC Electronic's basic classification of soldering methods and the recommended soldering conditions are shown below.


(1) Recommended soldering conditions of infrared reflow at 220°C
(2) Recommended soldering conditions of infrared reflow at 230°C
(3) Recommended soldering conditions of infrared reflow at 235°C
(4) Recommended soldering conditions of infrared reflow at 250°C
(5) Recommended soldering conditions of infrared reflow at 260°C
(6) Recommended soldering conditions of VPS
(7) Recommended soldering conditions of WS
(8) Recommended soldering conditions of partial heating

Notes1. The recommended peak temperature for infrared reflow soldering is 220°C, 230°C, 235°C, 250°C, or 260°C depending on the product. For details, consult an NEC Electronics sales representative.
Notes2. The number of times the product can be mounted is either once, twice or three times depending on the product. For details, consult an NEC Electronics sales representative.
Notes3. For details on the partial heating method, refer to the section on soldering methods.
When mounting a device using soldering iron or flow soldering, be sure to earth the soldering equipment via a 1 M ohm resistor to prevent power leakage.
