Data Sheet

19.0 Soldering

19.1 Introduction to Soldering Surface Mount Packages

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

Handbook IC26; Integrated Circuit Packages” (document order number 9398 652 90011). There is no soldering method that is ideal for

all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards (PCBs) with

high population densities. In these situations re-flow soldering is often used.

19.2 Re-flow Soldering

Re-flow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the PCB by

screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for re-flowing; for

example, infrared/convection heating in a conveyor type oven.

Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical re-

flow peak temperatures range from 215 to 260°C. The top-surface temperature of the packages should preferably be kept below 230°C.

19.3 Wave Soldering

Conventional single wave soldering is not recommended for surface mount devices (SMDs) or PCBs with a high component density, as

solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was

specifically developed.

If wave soldering is used the following conditions must be observed for optimal results:

• Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave.

• For packages with leads on two sides and a pitch (e):

Larger than or equal to 1.27mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of

the PCB;

Smaller than 1.27mm, the footprint longitudinal axis must be parallel to the transport direction of the PCB. The

footprint must incorporate solder thieves at the downstream end.

For packages with leads on four sides, the footprint must be placed at a 45° angle to the transport direction of the

PCB. The footprint must incorporate solder thieves downstream and at the side corners.

During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen

printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is four seconds

at 250°C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications.

19.4 Manual Soldering

Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24V or less) soldering iron applied to the flat

part of the lead. Contact time must be limited to 10 seconds at up to 300°C.

When using a dedicated tool, all other leads can be soldered in one operation within two to five seconds between 270 and 320°C.
