SOLDERING Introduction
There soldering method that ideal packages. Wave soldering often preferred when through-hole surface mounted components mixed printed-circuit board. However, wave soldering always suitable surface mounted ICs, printed-circuits with high population densities. these situations reflow soldering often used.
This text gives very brief insight complex technology. more in-depth account soldering found "Data Handbook IC26; Integrated Circuit Packages" (order code 9398 90011).
SDIP
Soldering dipping wave
maximum permissible temperature solder solder this temperature must contact with joint more than seconds. total contact time successive solder waves must exceed seconds.
device mounted seating plane, temperature plastic body must exceed specified maximum storage temperature (Tstg max). printed-circuit board been pre-heated, forced cooling necessary immediately after soldering keep temperature within permissible limit.
Repairing soldered joints
Apply voltage soldering iron (less than lead(s) package, below seating plane more than above temperature soldering iron less than remain contact seconds. temperature between contact seconds.
Reflow soldering
Reflow soldering techniques suitable packages.
Reflow soldering requires solder paste suspension fine solder particles, flux binding agent) applied
printed-circuit board screen printing, stencilling pressure-syringe dispensing before package placement.
Several techniques exist reflowing; example, thermal conduction heated belt. Dwell times vary between seconds depending heating method. Typical reflow temperatures range from
Preheating necessary paste evaporate binding agent. Preheating duration: minutes
Wave soldering
Wave soldering techniques used packages following conditions observed:
double-wave turbulent wave with high upward pressure followed smooth laminar wave) soldering technique should used.
longitudinal axis package footprint must parallel solder flow.
package footprint must incorporate solder thieves downstream end.
During placement before soldering, package must fixed with droplet adhesive. adhesive applied screen printing, transfer syringe dispensing. package soldered after adhesive cured.
Maximum permissible solder temperature maximum duration package immersion solder seconds, cooled less than within seconds. Typical dwell time seconds

Repairing soldered joints
