Thermal soakĪ specific temperature must be met to activate the flux present in the solder paste. This first step is a preparatory service for the boards before going through the soldering oven so they can readily comply.įor the quality of the solder paste to be maximized, the inconsistent solvents in it are expelled. Next, the primary process below commences after completing the two methods above. The components are accurately laid on top of the solder paste on the pads through a pick and place mechanism.The solder stencil paste is used to place the flux and solder (solder paste) on the pads uniformly.Initially, before the major reflow soldering commences, two critical operations are carried out. The components are temporarily stuck to their pads with solder and flux (also solder paste) before permanently joining by melting the solder paste using hot air or thermal radiation usually produced from a soldering oven. In Reflow soldering, permanent soldering joints are made from pre-existing temporary glues that stick the components to their pads on a circuit board. However, this method is limited because it cannot be used for hole soldering. This is a very common method engineers prefer to use. Read through this article and understand the favorable procedure for your specific business and how to maximize its usage. We give detailed applications of the two methods and the concise differences between them.įrom here on, deciding if to pick one method over another will be much easier. Hence, drafted in this article is a breakdown of all insights on the two soldering methods. Likewise, when a method fits your design requirements, it must be done correctly to avoid ineffectiveness. This is as the process can influence different aspects of PCB production like time, cost, and other significant factors.Ī proper rundown of the methods and all their features is necessary to determine if a technique meets the needs of your business. It is necessary to pick the best soldering method that suits your production processes of a required circuit board. Without soldering, components will fall off the boards or cannot be made to stick on them.Īlthough there are various soldering methods today, the two main methods are Reflow Soldering and Wave Soldering. It is one of the most critical steps in making a power circuit board mainly because soldering is used to join circuits to boards efficiently. Manufacturing Industries widely use a Soldering method when producing PCB (printed circuit board). Modern advancement has brought us to the immense use of chips and printed circuit boards.
