Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0017] figure 1 It is a process flow diagram of the copper clad welding process of the lightning protection product of the present invention, please refer to figure 1 , a copper-clad welding process for lightning protection products, which includes: closely attaching multiple copper bars to a circuit board, and the multiple copper bars are closely attached to one side of the circuit board; inserting components into the circuit board , the components are inserted from the other side of the circuit board; the circuit board is put into the wave soldering equipment for welding, and the equipment is directly used for welding, which ensures the accuracy and quality of welding, and also avoids the long process flow caused by manual welding, which is easy to appear For the problem of missing soldering, the copper bars and components are soldered on the circuit board...

Abstract

The invention discloses a lightning protection copper bonding process, comprising: tightly attaching a plurality of copper bars on a circuit board; inserting components into the circuit board; welding the circuit board in a wave-soldering device, wherein the copper bars and the components are welded on the circuit board; and completing welding. The prior art lacks the technique of soldering heavy current copper bars on a circuit board and performing detection; according to the invention, the copper bars are tightly attached on the circuit board, and are wave-soldered on the circuit board together with the components on the circuit board; after welding, the circuit board is electrified and is detected by an infrared heat imaging instrument, thereby firmly and rapidly welding and detecting the copper bars on the circuit board.

Description

technical field [0001] The invention relates to a welding process, in particular to a copper-clad welding process for lightning protection products. Background technique [0002] Today's technology is changing with each passing day, and the rapid development of technology brings people a wide range of electronic products. People are becoming more and more inseparable from electronic products, hoping that the longer the life of the product, the better. But there are many electronic products that cannot withstand the lightning strikes of nature. Therefore, lightning protection systems and lightning protection products are getting more and more attention. [0003] In some lightning protection products, it is often necessary to withstand lightning strikes, and the instantaneous current in the circuit is hundreds of times the normal working current of ordinary electronic products. The copper foil on the ordinary PCB cannot withstand such a huge current at all, so it is necessa...
