Description
Technical field:
The utility model relates to a kind of chemical condensing and recycling device, when being mainly used in packaging or non-packaging electronic circuit board in the electronics industry, accurate electronic circuit board pre-treatment or post processing residue, and when carrying out Chemical cleaning, the recovery of chemical.
Background technology:
PCBA needs to use tin cream, scaling powder to weld in process of production, contains scaling powder in the tin cream too; And scaling powder can produce residue, and these residues contain organic acid and decomposable electro-ionic residue, and wherein organic acid possibly cause corrosion to PCBA; And electro-ionic residue, in galvanization, because the existence of electrical potential difference can cause movement of electrons between two pads; Just might form short circuit, make product failure.And at present the spacing between the pad of electronic product is more and more littler, so the existence of residue has more increased the possibility of short circuit, so that cleaning in process of production just becomes is extremely important.
At present, along with the microminiaturization with components and parts that improves constantly of the density of components of circuit board, cleaning becomes a kind of unique feasible program that satisfies state-of-the-art technology.But for flip-chip, QFN, Micro BGA and small-sized chip capacitance resistance component, the welding assisted agent residuals below it is removed difficulty very.Unleaded processing procedure makes scaling powder require the higher resin or the content of rosin, and it is even more serious to make scaling powder pile up in little space like this, makes that the cleaning agent infiltration is difficult; Moreover be exactly higher unleaded temperature and repeatedly reflux course make welding assisted agent residuals clean more difficulty.In sum, the cleaning of electronics completed knocked down products more and more is not easy, and this solves these with regard to the cleaning that requires superior cleaning and cleans a difficult problem.
For avoiding the problems referred to above; Electronics manufactory great majority use the leave scaling powder, but along with the miniaturization of electronic product and the variation of function, I/O quantity improves constantly; The components and parts spacing is more and more small, and the application of product and the natural environment of use constantly extend expansion.The relative reliability of no-clean scaling powder receives unprecedented challenge; Exempting from the manufacturing process for cleaning of many products; Scaling powder does not have to show as through making it can produce the high temperature of polymerisation the characteristic of synthetic resin; Environment in humidity presents acid essence, to the solder joint generation corrosiveness of components and parts and PCB, therefore exempts from cleaning products is usually seen verdigris on its connector PIN pin or PCB golden finger or set screw hole after placement a period of time phenomenon.In addition; The residue of no-clean scaling powder is under the environment of humidity, and the surface ion residue can form the ingotism body, and ingotism cognition causes that electric migration causes short circuit; In no-clean scaling powder, be wrapped in the tin ball that from tin cream, dissociates out; These tin balls are to be difficult to remove without cleaning generally, are hidden danger for more and more littler element spacing, are a kind of corollaries so clean.
In the above-mentioned cleaning process, owing to need to use chemical to clean the various residues on the PCBA, and, must be heated to chemical the temperature of 55-60 degree earlier according to the needs that clean.And then PCBA is cleaned through the mode that pumping pressurization is sentenced high-pressure spraying from the nozzle on the spray boom; Therefore in spray, a part of chemical can form spray pattern, and reclaims for the chemical of this atomizing; Reduce the consumption of chemical liquid; Need to use the refrigeration system condensation, the chemical that forces atomizing through blower fan carries out condensation through condenser.Its implementation procedure is quite loaded down with trivial details, and it needs outside refrigeration system that energy is provided, so its cost is higher.
Summary of the invention:
For this reason, the purpose of the utility model is to provide a kind of condensing and recycling device, needs to use the external refrigeration system to solve at present chemical to be reclaimed, the problem that existing cost is high, and the while is also reduced the consumption and the operating cost of chemical liquid.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
A kind of condensing and recycling device; Comprise purge chamber (1) and rinsing chamber (14); Said purge chamber (1) is provided with the finned cooler (6) that is communicated with purge chamber (1); This finned cooler (6) is provided with water inlet (10) and delivery port (11), and said water inlet (10) is communicated with outside water route (17) through washings water inlet pipe (15), and said delivery port (11) is communicated with rinsing chamber (14) through washings outlet pipe (16).
Be provided with down spray bar (3) and last spray bar (4) in the wherein said purge chamber (1), be provided with between said spray bar (3) down and the last spray bar (4) and transmit guipure (2).
Also be provided with a chemical liquids case (5) in the wherein said purge chamber (1), this chemical liquids case (5) is positioned at the bottom of spray bar (3) down.
Wherein said finned cooler (6) one ends are communicated with purge chamber (1) left side through air inlet pipe (7) and left air inlet adjustment switch (8); One side is communicated with right side, purge chamber (1) through right air inlet adjustment switch (9).
Wherein said finned cooler (6) top also is connected with blower fan (13) through exhaust duct (12).
