The deposited copper welding procedure of lightning-protected product as described above, wherein, by multiple copper bars fit closely on circuit boards it
Before, customize multiple copper bars according to board structure of circuit.
The deposited copper welding procedure of lightning-protected product as described above, wherein, each copper bar is detected, whether obtains copper bar
The problem of with slight crack, deformation, oxidation.
The deposited copper welding procedure of lightning-protected product as described above, wherein, a hollowed-out board is covered on copper bar is close to copper bar
On circuit boards.
The deposited copper welding procedure of lightning-protected product as described above, wherein, after completing welding, the copper bar on circuit board is carried out
Repair welding.
The deposited copper welding procedure of lightning-protected product as described above, wherein, circuit board is detected after completing welding.
The deposited copper welding procedure of lightning-protected product as described above, wherein, be detected including：It is powered to circuit board,
By the infrared energy of infrared thermal imaging instrument circuit board for receiving, infrared thermography converts the energy signal received
For picture signal.
The deposited copper welding procedure of lightning-protected product as described above, wherein, the image and mark that infrared thermal imager is obtained
Quasi- image is compared.
In conclusion by adopting the above-described technical solution, the present invention solves lacks one kind in circuit in the prior art
The problem of technique that high current copper bar is welded on plate and is tested, by the way that copper bar is fitted closely on circuit boards, with electricity
Wave crest Welding on circuit boards, and after completing to weld, is powered by infrared to circuit board the component of road plate together
Thermal imaging system is detected circuit board, realizes copper bar secured rapid welding on circuit boards and detection.
Description of the drawings
Fig. 1 is the process flow chart of the deposited copper welding procedure of lightning-protected product of the present invention.
Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples：
Fig. 1 is the process flow chart of the deposited copper welding procedure of lightning-protected product of the present invention, refers to Fig. 1, a kind of lightning-protected product
Deposited copper welding procedure, wherein, including：Multiple copper bars are fitted closely on circuit boards, the one side of multiple copper bars and circuit board
Plate face is close to；Component is inserted into circuit board, component is inserted into from the opposite side of circuit board；Circuit board is put into Wave soldering apparatus
In welded, directly using equipment weld, ensure that the precision and quality of welding, also avoid technique caused by human weld
Long flow path, the problem of being susceptible to solder skip, copper bar are soldered on circuit boards with component；Complete welding.
Before the present invention fits closely multiple copper bars on circuit boards, multiple copper bars are customized according to board structure of circuit, this
The project compatibility of invention is strong, is adapted to a variety of circuit boards.
The present invention is detected each copper bar before multiple copper bars are fitted closely on circuit boards, and obtaining copper bar is
It is no that there is the problem of slight crack, deformation, oxidation, it ensure that the quality for the product of being eventually welded into.
In one embodiment of the invention, the present invention covers a hollowed-out board on copper bar makes copper bar be close to circuit board
On, copper bar is compressed patch on circuit boards by hollowed-out board, and the position that copper bar can be corresponded in hollow out version sets corresponding groove, will
Copper bar correspondence is placed in groove, is welded by wave crest welding machine, since hollowed-out board can have overlapping part with copper bar, because
This, may have the position that part can not be welded to.
Therefore, further, after the present invention completes welding, repair welding is carried out to the copper bar on circuit board.
The present invention is detected circuit board after completing welding, in specific implementation process of the invention, is examined after completing welding
There is solder skip in the welding situation of slowdown monitoring circuit plate, the circuit board for avoiding the problem that being welded.
The present invention be detected including：It is powered to circuit board, passes through the red of infrared thermal imaging instrument circuit board for receiving
The energy signal received is converted to picture signal by external radiation energy, infrared thermography, is carried out by infrared thermography
Detection has good detection result, avoids the omission occurred in detection process completely.
The present invention compares the image that infrared thermal imager obtains and standard picture, and infrared thermoviewer is obtained
Image imports computer, and image and standard picture are carried out comparison identification by computer, if coincide with standard picture, sent out
Go out qualifying signal, if be not inconsistent with standard picture, send unqualified signal.
