Description

Technical Field

[0001] The utility model relates to a guide point device, in particular to a guide point device for a soldering flux spraying area, and belongs to the technical field of soldering flux spraying. Background Art

[0002] As an advanced soldering technology, selective soldering plays a key role in numerous high-end fields, including military electronics, aerospace electronics, automotive electronics, digital cameras, and printer manufacturing. It is particularly well-suited for demanding and complex through-hole soldering of multi-layer PCBs. Its significant advantages lie in its efficiency and precision, applying solder only where necessary, effectively avoiding the potential problems associated with traditional wave soldering, which requires extensive coverage of the board. This improves production efficiency and enhances operational safety.

[0003] The selective soldering process includes key steps such as flux spraying, PCB preheating, dip soldering, and drag soldering. The flux spraying step is particularly critical, as it uses a nozzle to atomize the flux and evenly spray it onto the circuit board. This refined control method not only accurately controls the amount of flux used, reducing unnecessary waste, but also ensures uniform distribution of the flux on the circuit board, which is particularly important for soldering high-density, fine-pitch components.

[0004] However, the selective soldering equipment currently on the market suffers from efficiency issues during the flux spraying process. Before spraying, thermal paper must be applied underneath through-hole components on the PCB. The PCB is then placed in the equipment to adjust the spraying coordinates. This practice not only increases material consumption and process time, but also often makes it difficult to ensure successful first-pass adjustment, reducing overall production efficiency and flexibility. To address this issue, a device for pointing points in the flux spraying area is proposed. Utility Model Content
