Friday, June 20, 2014: SMT soldering machines help to ensure consistent soldering quality in a product. These machines are available as different types of equipment, including SMT reflow soldering (reflow ovens) systems, SMT/BGA soldering stations (used for single component placement/removal) also known as SMT/BGA rework stations, SMT discrete soldering equipment (or just soldering stations), hot tweezers, infrared guns, etc.

SMT soldering machines use less solder paste and labour. By using these machines, manufacturers can improve the thermal conductivity and lower the assembly costs. Today, these machines are very advanced and use the latest soldering technology, which can reliably solder surface mounted components.

Reflow ovens, a major part of the soldering system, are of two types —infrared and convection ovens. These ovens comprise multiple zones, which can each be individually controlled for temperature. Here are some of the latest soldering systems.
