Description

Technical Field

[0001] This utility model belongs to the field of reflow oven technology, and in particular relates to a dual-channel reflow oven that is easy to maintain. Background Technology

[0002] Due to the increasing miniaturization of PCBs in electronic products, chip components have emerged, rendering traditional soldering methods inadequate. Initially, reflow soldering was only used in the assembly of hybrid integrated circuit boards, primarily for chip capacitors, chip inductors, surface-mount transistors, and diodes. As surface mount technology (SMT) has matured, the emergence of various surface-mount components (SMCs) and surface-mount devices (SMDs) has led to the development of reflow soldering technology and equipment, which are now widely used in almost all electronic product fields. Consequently, traditional soldering techniques can no longer meet the demands, and reflow soldering technology has become widely adopted in the electronics manufacturing industry.

[0003] A reflow oven contains a heating circuit that heats air or nitrogen to a sufficiently high temperature and blows it onto the circuit board where components have been attached. This melts the solder on both sides of the components, causing them to bond to the motherboard. The advantages of this process are that the temperature is easy to control, oxidation can be avoided during the soldering process, and manufacturing costs are easier to control.

[0004] Most existing reflow ovens are single-channel with a fixed channel direction, resulting in low welding volume, low welding efficiency, and inconvenient maintenance. In response, this application proposes a dual-channel reflow oven that is easier to maintain. Utility Model Content
