1 Introduction to Soldering Surf
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
ndbook IC26; Integrated Circuit Packa
Ha
ges” (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
it boar
ICs, or for printed-circu
ds with high population densities. In these situations reflow soldering is often used.
20.2 Re
Re-flow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit
board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for re

mperatures range from 215 to 250°C. The top-surface temperature of the packages should preferably be kept
ve Soldering
soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high
omponent density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave
oldering method was specifically developed.
wave soldering is used the following conditions must be observed for optimal results:
