We call this process infrared reflow soldering. When an operator places an electronic product inside the device, it precisely applies surface mount components to the printed circuit board (PCB). These machines vary in size from small boxy ovens to inline- or conveyor-belt-style options. The assembly is lead-free so the reflow oven is running at the elevated temperatures needed for that. A SMT reflow oven is an essential machine of the thermal processing of solder for electronics manufacturing. That makes it a total of 4 passes through a reflow oven for the bottom side and 3 times through for the top side. Large size: It is a reflow oven that can handle larger size PCB in the same shape and size of the body, double track can be over 300 mm at the same time, and the single board can reach 550mm, which can meet the demand of many customers. Reflow soldering is the process of attaching surface components to the printed circuit boards (PCBs). Ensure PCB trace routes connected to components are similar in size. Finally, this newly created SMT module is placed on another pcb and again run through a reflow oven. Reflow solder profiles usually have four stages, preheat, thermal soak, reflow and cooling. The solder profile is influenced by the number of layers in the PCB, the copper distribution on the board, the number and size of components. Low power consumption : Verified by theory and practice, our products are able to minimize the temperature consumption between different size of components in order to achieve the best heat evenness.Įven heat distribution : By actual field experience, our products get lowest power consumption and measured by repeatability test with high CPK value. Solder profiles need to be optimised for each individual assembly job. High Heat performance : Achieving high heat efficiency by professional thermal knowledge and simulation of the matching between heat consumption and capacity, then heating zone is shortened and reflow oven machine production capacity is optimized. Space saving and low energy consumption, the machine has lots advantage of a larger reflow-soldering oven such as perfect thermal properties as well as comprehensive equipment including useful features. SunzonTech’s SER-710D 10 zones lead-free hot air PCB reflow oven (Left to right ,dual-rail) is the space-saving and inexpensive solution for most of standard SMT soldering process. To educate PCB design engineers, this article aims to elaborate how to achieve optimal solder reflow profiles and avoid common Printed Circuit Board.
