Description

Technical Field

[0001] The invention relates to the technical field of tin spraying, and in particular to a tin spraying device and a tin spraying method for a long circuit board. Background Art

[0002] Tin spraying is a surface treatment process that changes the performance and characteristics of the substrate by coating a layer of tin on the surface of the substrate. It can provide the substrate with multiple functions such as lubrication, corrosion protection, conductivity, and aesthetics. It is widely used in multiple industrial fields such as electronics, communications, automobiles, and aviation.

[0003] The tin spraying process usually involves immersing a long circuit board in a molten solder pool so that all exposed copper surfaces are covered with solder, and then the excess solder on the long circuit board is removed by a hot air cutter. Since harmful gases to the human body are generated during the tin spraying process, most tin spraying devices are usually provided with a loading port and a unloading port when in use to facilitate loading and unloading. As a result, some harmful gases will drift out of the tin spraying device through the loading and unloading ports, causing air pollution and posing certain safety hazards. In addition, a large amount of heat will be generated during the tin spraying process, and most tin spraying devices usually use manual loading and unloading, which is prone to burns and is inconvenient for daily use. In response to the above problems, the inventor proposes a tin spraying device and a tin spraying method for a long circuit board to solve the above problems. Summary of the invention
