SOLDERING 15.1 Introduction soldering surface mount packages
TDA9887
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 leads wave ranges from seconds seconds depending solder material applied, SnPb Pb-free respectively. mildly-activated flux will eliminate need removal corrosive residues most applications. 15.4 Manual soldering
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. 15.2 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. Driven legislation environmental forces worldwide lead-free solder pastes increasing. Several methods exist reflowing; example, convection convection/infrared heating conveyor type oven. Throughput times (preheating, soldering cooling) vary between seconds seconds depending heating method. Typical reflow peak temperatures range from depending solder paste material. top-surface temperature packages should preferably kept: below (SnPb process) below (Pb-free process) BGA, HTSSON-T SSOP-T packages packages with thickness packages with thickness volume called thick/large packages. below (SnPb process) below (Pb-free process) packages with thickness volume called small/thin packages. Moisture sensitivity precautions, indicated packing, must respected times. 15.3 Wave 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 seconds between
Conventional single wave soldering recommended surface mount devices (SMDs) printed-circuit boards with high component density, solder bridging non-wetting present major problems.
