SOLDERING

Introduction

There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and

surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for

surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often

used.

This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our

“IC Package Databook” (order code 9398 652 90011).

Soldering by dipping or by wave

The maximum permissible temperature of the solder is 260

°C; solder at this temperature must not be in contact with the

joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.

The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the

be necessary immediately after soldering to keep the temperature within the permissible limit.

Repairing soldered joints

Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more

than 2 mm above it. If the temperature of the soldering iron bit is less than 300

°C it may remain in contact for up to

10 seconds. If the bit temperature is between 300 and 400

°C, contact may be up to 5 seconds.

Limiting values

Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or

more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation

of the device at these or at any other conditions above those given in the Characteristics sections of the specification

is not implied. Exposure to limiting values for extended periods may affect device reliability.

Application information

Where application information is given, it is advisory and does not form part of the specification.
