Description
Technical Field
The utility model relates to a whole-course nitrogen-filled tin furnace.
Background
At present, the common tin furnace has the following limitations: because the common tin furnace is coated with the soldering flux firstly and then preheated, the following two troubles appear when the common tin furnace is used for dealing with elements with large heat capacity and elements with large grounding copper foil layers and large area: a. raising the preheat temperature or increasing the preheat time to achieve a sufficient temperature for the component to cause the applied flux to bake out and fail, thereby affecting the tin level on the component; b. in order to ensure that the soldering flux is not baked and the activity is kept, the temperature of the element with large heat capacity and the element with large area and more layers of grounding copper foil is not enough, and the tin coating height of the element is further influenced.
Therefore, how to provide the whole-course nitrogen-filled tin furnace for avoiding the influence on the tin-feeding height caused by poor preheating becomes a problem to be saved.
Disclosure of Invention
The utility model aims to solve the technical problem that a whole nitrogen tin furnace that fills is provided, it can avoid because preheat harmfully lead to influencing the tinning height
In order to solve the technical problem, the utility model provides a whole nitrogen-filled tin furnace, it carries out the soldering operation to the PCB board, and the PCB board passes through a transmission mechanism and runs in this whole nitrogen-filled tin furnace, and this whole nitrogen-filled tin furnace includes a first preheating module, a spraying module, a second preheating module, a soldering tin module and a cooling module in proper order;
the first preheating module is used for heating the PCB on the transmission mechanism for the first time before soldering flux spraying, so that the electronic elements on the PCB absorb part of heat;
the spraying module is used for spraying soldering flux on the PCB after the PCB is heated for the first time;
the second preheating module is used for heating the PCB after the soldering flux is sprayed for the second time, so that the soldering flux on the PCB absorbs heat and electronic elements on the PCB absorb part of heat again;
the soldering tin module is used for carrying out soldering tin operation on the PCB after the second heating;
the cooling module is used for cooling the PCB after soldering operation.
Preferably, the flux is rosin.
Compared with the prior art, the utility model discloses a whole journey fills nitrogen tin stove can carry out the first time heating before treating welded PCB board and carry out the spraying scaling powder to let the component on the PCB board, especially the big component of thermal capacity and the ground connection copper foil number of piles is many, the big component of area heats in advance, heats once more after the spraying scaling powder after that, thereby guarantees that component temperature and scaling powder on the PCB circuit board reach the best temperature before the welding simultaneously, improves the last tin height of component, promotes the product quality.
[ description of the drawings ]
FIG. 1 is a block schematic diagram of the whole course nitrogen-filled tin furnace of the present invention.
[ detailed description ] embodiments
Please refer to fig. 1, the utility model provides a whole nitrogen tin furnace 1 that fills, it carries out the soldering operation to the PCB board, and this PCB board is in through a transmission mechanism the utility model discloses a whole nitrogen tin furnace 1 that fills moves, the utility model discloses a whole nitrogen tin furnace 1 that fills includes that a first preheating module 10, a spraying module 11, a second preheat module 12, a soldering tin module 13, a cooling module 14 in proper order.
The first preheating module 10 is configured to heat the PCB located on the conveying mechanism for the first time before flux spraying, so that the electronic components on the PCB absorb a part of the heat.
The spraying module 11 is used for spraying a soldering flux on the PCB after the first heating, wherein the soldering flux may be rosin or the like.
The second preheating module 12 heats the PCB after the soldering flux is sprayed for the second time, so that the soldering flux on the PCB absorbs heat and simultaneously allows the electronic components on the PCB to absorb a part of heat again.
And a soldering module 13 for performing a soldering operation on the PCB after the second heating.
And a cooling module 14 for cooling the PCB after the soldering operation.
Through the utility model discloses a whole journey fills nitrogen tin stove 1, can carry out the first time heating before treating welded PCB board and carry out the spraying scaling powder to let the component on the PCB board, especially the big component of thermal capacity and the ground connection copper foil number of piles is many, the big component of area heats in advance, heats once more after the spraying scaling powder after that, thereby guarantees that component temperature and scaling powder on the PCB circuit board reach the best temperature before the welding simultaneously, improves the tinning height of component, promotes the product quality.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
