Description
Technical field
The utility model relates to the reflow soldering annex, especially relates to a kind of device that is used to collect gas heat exchange cooling scaling powder.
Background technology
Reflow soldering (Reflow Oven) is the equipment that is used for the circuit board that is loaded with electronic devices and components is carried out soldering.It is through providing a kind of heating environment, thereby solder(ing) paste being heated melt lets surface-pasted components and parts and circuit board combine reliably through the solder(ing) paste alloy.The solder(ing) paste that soldering is used is that the scaling powder and the powder scolder of smectic are processed paste; Be coated in the soldering position of each components and parts of circuit board through printing; And accurate above that mounted with electronic components, utilize reflow soldering to carry out heat fused, reach reliable soldering to components and parts.
Scaling powder in the solder(ing) paste is the mixture of main component with rosin normally, is the auxiliary material that guarantee that brazing process carries out smoothly.The main effect of scaling powder is to remove scolder and by the oxide on weldering mother metal surface, make the metal surface reach necessary cleannes, and the oxidation once more on surface when preventing to weld reduces solder surface tension force, improves welding performance.During the heat fused solder(ing) paste, scaling powder can gasify and become steam.Can liquefy when low-temperature space (about below 110 ℃) time that the scaling powder of gasification touches in the reflow ovens.If when temperature was enough low, scaling powder can be become solid-state by liquid state, this is the state of temperature characteristic of scaling powder.
Except heating module, all there is a refrigerating module to guarantee that metallurgy characteristic plate temperature with reducing in the reflow soldering.In the air reflow soldering, scaling powder steam was directly discharged body of heater before cooling, in refrigerating module, can not stay the scaling powder condensate., in most nitrogen protection reflow solderings, in order to reduce the consumption of nitrogen (N2); Internal mix gas will recycle; Scaling powder steam can not directly be discharged body of heater, so scaling powder steam has an opportunity fully to contact with refrigerating module, makes its temperature be lower than 110 ℃; And condensation appears, these scaling powder condensate liquids are known from experience on the backflow orifice plate attached to refrigerating module.When the scaling powder of liquid state is stacked into certain degree, just can form drop, finally drip, and have very big probability to drop onto on the wiring board (PCB), cause the off quality of wiring board even scrap.In order to prevent this type of incident, general way is the scaling powder of regular manual wipping cleaning cooling zone backflow orifice surface in the industry, and maintenance is cleaned in return-flow system inside.The skilled worker that abundant maintenance technology and general knowledge generally need be shut down and arranged to have to this work operates, and also need dismantle correlated parts sometimes, to clear up easily and thoroughly and to safeguard.But increased the time and the work difficulty of maintenance so again, thereby remote-effects are to production efficiency and the output of using the client.
In order to reduce the continuous accumulation of scaling powder in burner hearth; Reduce the scaling powder probability that condensation is piled up in refrigerating module; The lower circuit board of enhanced cooling acquisition simultaneously goes out plate temperature, and reflow soldering should be equipped with soldering flux collection device, and the scaling powder of gasification is collected.To improve the service efficiency and the production efficiency of reflow soldering, be the bigger economic benefit of enterprises implement.
Scaling powder is collected and cooling device generally is free air cooling but to collect and two kinds of forms of cold water cooling collection; Utilize the state of temperature characteristic of scaling powder; The gas that burner hearth inside is full of scaling powder is extracted out, gets into scaling powder and collects and cooling device, makes this gas temperature be reduced to the temperature of scaling powder liquefaction through heat exchange; Thereby the scaling powder liquefy is separated out, and is collected by this device.Cooled gas flows back into the cooling zone again, reduces the cooling zone temperature simultaneously.In actual the use, need only carry out periodic maintenance and maintenance to scaling powder collection and cooling device.
The form that cooling is collected for cold water; Need to be equipped with the water source that special handpiece Water Chilling Units is used to provide cooling usefulness, will have corresponding water circuit system to be used for the detection of water temperature, generally involve great expense in reflow soldering equipment the inside; The risk that exists sealing to leak is simultaneously limited by application conditions.
The form that cooling is collected for air adopts ambient room temperature gas as cooling source, comes the gas of the inner band scaling powder of extracting out of cooled hearth through heat exchanging pipe.
