Description
Technical field
The present invention relates to a kind of welding procedure, the nitrogen-free welding procedure of a kind of rectifier bridge pin.
Background technology
Rectifier diode chip is enclosed in a shell by rectifier bridge exactly, is welded together with chip by pin.Rectifier bridge is as one
Plant power component, be widely applied to various power-supply device, realize the alternating voltage of input to be converted into the direct current of output
Voltage.
The welding procedure of traditional rectifier bridge pin is: is put in chain type soldering furnace by rectifier bridge pin and welds, needs nitrogen
Protection, accordingly, it would be desirable to nitrogen making machine prepares nitrogen, gas use cost is high, and power of motor consumes big；Have a large amount of during welding simultaneously
Waste gas discharges, and operation is relatively difficult to ensure that card pad welding is firm, and temperature control is the highest is easily damaged chip therein, and temperature is low
Time weld tabs can not be the most melted, failure welding, and face of weld bubble is many, makes the performance of chip itself to give full play of.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of while ensureing that welding quality is excellent, it is not necessary to
Nitrogen is protected thus is greatly reduced cost, and non-exhaust emission, the nitrogen-free welding procedure of the rectifier bridge pin of Environmental Safety.
The present invention is achieved by the following technical solutions:
The nitrogen-free welding procedure of a kind of rectifier bridge pin, comprises the steps:
Step 1, preparing scaling powder, described scaling powder includes dehydrated alcohol and Colophonium, takes dehydrated alcohol 9～12 by weight ratio
Part, Colophonium 1 part configuration scaling powder；
Step 2, rectifier bridge pin, weld tabs and chip to be welded are put between upper and lower mould；
Step 3, take one welding case, appropriate scaling powder is poured into welding case inner bottom part, then welding bottom portion place
Support, puts on bracing frame by the upper and lower mould being placed with rectifier bridge pin to be welded, closes the lid and is sealed by welding case；
Step 4, the welding case of above-mentioned good seal is put in chain type nitrogen-free soldering furnace and welds, it is ensured that welding the temperature inside the box exists
Constant temperature 15～20 minutes between 320 DEG C～370 DEG C；
Step 5, weld complete, take out welding case, open lid take out upper and lower mould, open upper mold room temperature cooling.
As the preferred implementation of the nitrogen-free welding procedure of above-mentioned rectifier bridge pin, described step 4 ensures welding the temperature inside the box
340 DEG C of constant temperature 15 minutes.
As the preferred implementation of the nitrogen-free welding procedure of above-mentioned rectifier bridge pin, the length, width and height within described welding case are a size of
During 280mm*200mm*220mm, its scaling powder used is 10 grams.
The present invention has the advantage that compared to existing technology
1, owing to adding a welding case sealed, place, in welding case, the scaling powder being made up of Colophonium and dehydrated alcohol, can be very
Good discharges the air in welding case, it is ensured that welding quality is excellent, and solder side bubble is few, and the function making chip itself can be fully
Bring into play；
2, welding process is protected without nitrogen, eliminates nitrogen making machine, greatly reduces the use cost of gas, reduce nitrogen making machine
The power attenuation of motor, and non-exhaust emission, Environmental Safety during welding；
3, welding efficiency is high, originally needs the work that 3 people complete, and present 1 people can complete.
Detailed description of the invention
Elaborating embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention,
Give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
The nitrogen-free welding procedure of a kind of rectifier bridge pin that the present invention provides, comprises the steps:
Step 1, preparing scaling powder, described scaling powder includes dehydrated alcohol and Colophonium, takes dehydrated alcohol 9～12 by weight ratio
Part, Colophonium 1 part configuration scaling powder；
Step 2, rectifier bridge pin, weld tabs and chip to be welded are put between upper and lower mould；
Step 3, take one welding case, appropriate scaling powder is poured into welding case inner bottom part, then welding bottom portion place two
Individual bracing frame, bracing frame is triangular prism shape horizontal positioned, and the upper and lower mould being placed with rectifier bridge pin to be welded is put into bracing frame
On, bracing frame serves balance, the effect preventing upper and lower mould from contacting with welding bottom portion, closes the lid and is sealed by welding case；
Step 4, the welding case of above-mentioned good seal is put in chain type nitrogen-free soldering furnace and welds, with in probe detection welding case
Temperature, it is ensured that welding the temperature inside the box constant temperature 15～20 minutes between 320 DEG C～370 DEG C；The Colophonium in case is welded during Gai
Gradually being heated with dehydrated alcohol, the air in welding case is discharged by Colophonium and the dehydrated alcohol raw cigarette that persistently volatilizees, at 320 DEG C～
Constant temperature 15～after 20 minutes between 370 DEG C, scaling powder volatilization is complete, and rectifier bridge pin also welds.Through repetition test, make
Temperature in welding case, 340 DEG C of constant temperature 15 minutes, can reach optimal welding effect, and after welding, pad is quite firm, and
Solder side bubble is few, and chip performance is good；
Step 5, weld complete, take out welding case, open lid take out upper and lower mould, open upper mold room temperature cooling.
As the preferred implementation of the nitrogen-free welding procedure of above-mentioned rectifier bridge pin, when welding the length, width and height within case a size of
During 280mm*200mm*220mm, its scaling powder used is 10 grams, by that analogy.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and former
Any amendment, equivalent and the improvement etc. made within then, should be included within the scope of the present invention.
