Description
Technical field
The present invention relates to a kind of tin ball production method, particularly relate to the production method of a kind of BGA with solder ball.The invention still further relates to a kind of equipment that in aforementioned production method, uses.
Background technology
The BGA solder ball be granularity sphere diameter scope be 0.2mm～1.2mm all size (all size tolerance can reach ± 0.02mm), outward appearance is spherical, the ganoid welding tin ball of all grains.The method of producing the tin ball in the prior art has two kinds: (1) adopts high pressure draught to blow striking, promptly adopts high pressure draught to blow and hits the drippage tin liquor, becomes tiny tin ball.Or blow the tin liquor of hitting on the square position that is dropped in a rotation with high pressure draught, make it become tiny tin ball.Be shrunk to bead in the process that they are run fast aloft.(2) earlier solder stick is drawn into filament, cuts into dices again,, make its surface shrink nodularization through a hot-zone.Above-mentioned two kinds of methods all exist product spherical undesirable, and are higher as special-shaped ball occurrence rate, and various granularity yield rates are difficult to shortcomings such as control and equipment complex structure.
Summary of the invention
The object of the present invention is to provide spherical comparatively desirable, the special-shaped ball of a kind of product the BGA solder ball production method that less, various granularity yield rate is easy to control to occur.
Another object of the present invention is to provide a kind of simply constructed equipment of producing above-mentioned BGA with solder ball.
Purpose of the present invention is achieved by the following technical programs.
BGA of the present invention is to adopt novel continuous feed to throw the liquid method at a high speed with the production method of solder ball, and step such as comprise fusing, insulation, moulding, taking-up, cleaning, oven dry, sieve, select is characterized in that:
(1) fusing: with tin material heat fused, make liquid Xi Wendu be elevated to 〉=450 ℃;
(2) insulation: the temperature of liquid tin is controlled in the scope of tapping temperature ± 30 ℃;
(3) moulding: liquid tin is splashed into rotating speed continuously equably reach in 800～2000 rev/mins and be preheated to 〉=250 ℃ the flinger, from flinger, penetrate then, fall into the temperature that constant temperature liquid is housed and be 40 ℃～90 ℃ container, and cooling and shaping becomes the tin ball therein.
In the above-mentioned fusing step, the preferred temperature of liquid tin is between 450 ℃～500 ℃; In the incubation step, preferred 450 ℃ ± 10 ℃ of the temperature range of liquid tin; In the forming step, the preferred rotating speed of flinger in 1000～1500 rev/mins scope, the preferred preheat temperature scope of flinger between 400 ℃～500 ℃, preferred 60 ℃～70 ℃ of the temperature of constant temperature liquid.At the production of different size tin ball, above-mentioned each temperature conditions has different preferred values with the flinger rotating speed.
Fusing in the aforementioned production method, insulation, forming step can be realized by the equipment of a cover particular design, it comprises melting furnace, holding furnace, pipeline, shaped device, wherein melting furnace and holding furnace link together by pipeline, liquid tin flows out in holding furnace, send in the shaped device by pipeline, it is characterized in that: described shaped device comprises flinger, mixer, constant temperature liquid and constant temperature fluid bath, wherein said flinger is formed by throwing net and carriage, be bowl-shape throwing net and constitute the flinger inwall, the carriage support is thrown net, throw the groove that sieve bottom has an annular, the groove cross section is an arc, flinger is fixed on the end of puddler in the mixer, the liquid outlet of pipeline faces throws online groove top, so that tin liquor just in time is dropped into groove, the constant temperature fluid bath of interior dress constant temperature liquid is positioned at the flinger below, accepts the borne tin droplets that penetrates from flinger.
The radius of curvature of described groove can be in the scope of 5mm～20mm, and the preferred curvature radius is between 5mm～10mm, so that the tin ball that penetrates from flinger just in time falls into constant temperature fluid bath.
The mesh size of described throwing net is more bigger than the tin ball sphere diameter of producing, preferred big 0.1mm, so that the tin ball is easy to dish out, size and shape also are easier to control simultaneously.
The liquid level distance of described flinger and constant temperature liquid is preferably in 5～10cm scope, and distance is too big, and the situation that the tin ball is oval ball or irregular contour increases, and distance is too little, the slimeball phenomenon can occur again.
Described constant temperature liquid can adopt vegetable oil, glycerine, benzinum or atoleine, so that the borne tin droplets that penetrates from flinger natural subsidence at a certain temperature, cooling is simultaneously shunk, and makes the surface tension of tin ball can be able to equilibrium, finally forms circular tin ball.In addition, use vegetable oil, glycerine, benzinum or atoleine also can make the tin ball be easier to clean.
The temperature of constant temperature liquid of the present invention remains between 50 ℃～80 ℃ better, because the too high slimeball phenomenon that is easy to generate of temperature, temperature is crossed the low situation that produces irregular ball that also can make and increased.
In order accurately to control the flow of tin liquor, can set up flow valve at the outlet end of described melting furnace and the outlet end of holding furnace.
The collection of tin ball for convenience and taking out from constant temperature fluid bath can be placed in constant temperature fluid bath and be received the ball bag, and the sack of receipts ball bag is fixed on the notch place of constant temperature fluid bath.
Production method of the present invention and equipment also can be used for producing Pb-free solder ball.
The present invention compared with prior art has following advantage: (1) has adopted continuous feed to throw the liquid method at a high speed, makes the product of producing spherical better; (2) control the different grain size granulating rate by changing flinger inwall throwing screen distance, make the yield rate of various granularities be easy to control; (3) simple in equipment, easy operating is invested little; (4) output can be controlled on demand flexibly.
