SOLDERING Introduction soldering surface mount packages This text gives very brief insight complex technology. more in-depth account soldering found "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 90011). There soldering method that ideal surface mount packages. Wave soldering still used certain surface mount ICs, suitable fine pitch SMDs. these situations reflow soldering recommended. Reflow soldering 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 methods exist reflowing; example, convection convection/infrared heating conveyor type oven. Throughput times (preheating, soldering cooling) vary between seconds depending heating method. Typical reflow peak temperatures range from top-surface temperature packages should preferable kept below thick/large packages, below small/thin packages. Wave soldering Conventional single wave soldering recommended surface mount devices (SMDs) printed-circuit boards with high component density, solder bridging non-wetting present major problems. overcome these problems double-wave soldering method specifically developed.

wave soldering used following conditions must observed optimal results: double-wave soldering method comprising turbulent wave with high upward pressure followed smooth laminar wave. packages with leads sides pitch (e): larger than equal 1.27 footprint longitudinal axis preferred parallel transport direction printed-circuit board; smaller than 1.27 footprint longitudinal axis must parallel transport direction printed-circuit board. footprint must incorporate solder thieves downstream end. packages with leads four sides, footprint must placed angle transport direction printed-circuit board. footprint must incorporate solder thieves downstream side corners. During placement before soldering, package must fixed with droplet adhesive. adhesive applied screen printing, transfer syringe dispensing. package soldered after adhesive cured. Typical dwell time seconds mildly-activated flux will eliminate need removal corrosive residues most applications. Manual soldering component first soldering diagonally-opposite leads. voltage less) soldering iron applied flat part lead. Contact time must limited seconds When using dedicated tool, other leads soldered operation within seconds between
