SOLDERING 16.1 Introduction soldering surface mount packages

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 depending solder material applied, SnPb Pb-free respectively. mildly-activated flux will eliminate need removal corrosive residues most applications. 16.4 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. 16.2 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 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. 16.3 Wave soldering
