Abstract
The utility model provides a tin ball washer. The lower part of the utility model is provided with a machine table which can control an instrument; a motor is arranged in the machine table; the upper part of the machine table is fixed with two rotating shafts which are driven by the motor by a bearing seat; bevel gears are arranged on the rotating shafts, and the bevel gears are engaged with bevel gears which are positioned on driving shafts of the lower part of inclined washing tanks; the upper part of each washing tanks is provided with conveying pipes which are communicated with each other. The utility model is used for washing tin balls, oxide layers of the surface of the tin balls and impurities can be thoroughly and cleanly washed, washing agents which are used can be recovered and reused, and the environment can not be polluted.
Description
The utility model relates to a kind of employed tin ball cleaning machine invention in producing semiconductor chip BGA, the used tin ball of CSP welded encapsulation equipment process.
The tin ball is the BGA that welded encapsulation adopts (ball grid array of package) of large scale integrated circuit semiconductor chip in the current international microelectronic industry, the essential raw material of CSP (chip scale package) equipment.The tin ball used as welded encapsulation only has indivedual manufacturer production in the world, and its production technology all is to adopt tin is fused into to be sprayed into after the tin liquor further to be machined to finished product tin ball again after granular; Concrete processing technology and production equipment are all holded in close confidence as know-how.Since the easily oxidation and contain impurity of metallic tin surface, thus need in process of production it is cleaned, but still do not have a kind of tin ball cleaning machine that is used to clean the tin ball at present.
The purpose of this utility model is a kind of tin ball cleaning machine that can thoroughly remove tin ball surface oxidation layer and impurity of invention.
The feature of the tin ball cleaning machine that the utility model is invented is that its bottom is the board of a band control instrument, be provided with motor in the board, board top has been fixed two by motor-driven rotating shaft by bearing block, rotating shaft is provided with bevel gear, bevel gear engagement on the purge tank bottom driving shaft of bevel gear and inclination, each purge tank top is provided with the carrier pipe that communicates.
Use the above-mentioned tin ball cleaning machine of the utility model to clean the tin ball, the oxide layer and the impurity on tin ball surface thoroughly can be cleaned up, and can reclaim employed cleaning agent.
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the front view of Fig. 1.
In embodiment accompanying drawing 1, tin ball cleaning machine bottom is a board 1, be provided with control instrument and motor in the board 1, two driving shafts 3 have been fixed by bearing Cuo 2 in the top of board 1, driving shaft 3 is by the driven by motor in the board, driving shaft 3 is provided with bevel gear, and the bevel gear in the rotating shaft of bevel gear and clear Xian's jar 5 bottoms is meshed, and purge tank 5 is obliquely installed; Purge tank 5 bottoms are provided with carrier pipe 6, and each purge tank 5 is communicated with each other.Tin ball cleaning machine is when cleaning the tin ball, hold tin ball and cleaning fluid in the purge tank 5 simultaneously, because purge tank 5 is inclined, so originating from purge tank 5, changes and autogenous grinding by the tin ball, lip-deep oxide layer of tin ball and impurity will be ground off, cleaning agent can be reused after carrier pipe flows into the recycling bin recovery simultaneously, and free from environmental pollution.
