Abstract

PURPOSE:To coat uniformly a flux by immersing a foamed body of which at least the top surface is made flat into the flux in such a way as to parallel the top surface thereof with the top surface of the flux and feeding air in the flux thereby making the propagating distance of foam equal and the size of the foamed flux the same. CONSTITUTION:A foamed body 7 which is made into a flat plate shape is used and is installed roughly in parallel with the top surface of a flux 4. Said body is covered with a holder 8 so as to all the air fed through a pipe 3 into the same is ejected through the body 7. The foamed flux is then generated only on the flat top surface side of the body 7 and since the propagating distance to the top surface of the flux is equal, the size of the foamed flux is the same.

The flux 4 filled in the container 1 is foamed by sending air from the outside through a pipe 3, and the foamed flux 4 is applied to the back surface of the printed wiring board 6 through a nozzle 5. . By the way, in this kind of foam body 2, the foam body 2 is formed in a cylindrical shape, and the air fed through the pipe 3 is configured so as to blow out from numerous holes formed around the entire circumference of the foam body 2. Therefore, the size of the foamed flux differs greatly between the foamed flux formed above and below the foam 2 due to the difference in the propagation distance of the bubbles to the upper surface of the flux, and the printed wiring There was a problem in that the amount of flux applied to the back surface of the plate 6 was significantly non-uniform.

を目的とするものである。Purpose of the Invention The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks, and an object thereof is to provide an excellent flux coating device that can uniformly and evenly coat a printed wiring board with 7 Ranox with a simple configuration. It is something.

It is characterized by a dipping arrangement, and in particular, it is constructed so that the foamed flux is uniform in size by forming the foam into a flat plate shape.

Items with the same reference numerals as those in the figures indicate the same items. 7 is a foam made of sintered alloy, bisque, etc. formed into a flat plate and placed parallel to the upper surface of the flux 4; 8 holds a foam γ; / (This is a holder that covers so that all the air is blown out through the foam 7. With this configuration, the foamed flux is generated only on the peaceful upper surface of the foam 7) and reaches the top surface of the flux. Since the bubble propagation distances are equal, the size of the foamed flux is the same, and the printed wiring board 6 is always uniformly coated.

尚、実施例では発泡体７全体を平板状に形成しているが
、少なくとも上面のみフラットに形成されているもので
あｔばはソ同様の効果を得ることができ、これに代える
ことも可能である。In the example, the entire foam 7 is formed into a flat plate shape, but if at least only the upper surface is formed flat, the same effect as in the case can be obtained, and it is also possible to replace this. It is.

る。Effects of the Invention As is clear from the above embodiments, the flux applicator of the present invention uses a flat plate as the foam and is arranged parallel to the upper surface of the flux. The size of the foamed flux formed by blowing air through it becomes almost the same, and it is always uniformly applied to the printed wiring board. Therefore, according to the present invention, the subsequent soldering work becomes extremely uniform, which is extremely advantageous in practice.
