Reflow soldering is the most widely used method for attaching\u00a0<strong>Surface Mount Technology (SMT) components<\/strong>\u00a0to printed circuit boards (PCBs). It ensures strong, reliable solder joints by heating the solder paste to a controlled temperature, allowing it to melt and bond components securely.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Pre-Heating<\/h3>\n\n\n\n<p>The PCB enters the reflow oven, where it is gradually heated to activate the flux and remove moisture. There pre-heat parameters are defined as per solder paste supplier recommendations and varies for various type of solder paste used in the electronics manufacturing Industry.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Reflow<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The temperature is raised above the solder\u2019s melting point and this is the phase where the solder joints are made.<\/li>\n\n\n\n<li>In this phase of the reflow process, the solder liquefies, forming strong electrical and mechanical connections.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Cooling Zone<\/h3>\n\n\n\n<p>The PCB is gradually cooled to solidify the solder joints.
