Abstract
A kind of fixture for the process of chip back of the body gold, comprise the chassis of silicon material, its improvement is: the upper surface on chassis is provided with the movable type frame be made up of L shape sheth, bar shaped frame bar and many bar shaped compartmentation strips, and the region that L shape sheth, bar shaped frame bar and bar shaped compartmentation strip surround forms the rectangle clamping district of a variable area.Advantageous Effects of the present utility model is: be convenient to the chip after to scribing and carry on the back gold process, convenient, practical, working (machining) efficiency is higher.
Description
Technical field
The utility model relates to a kind of chip back of the body technology for gold, particularly relates to a kind of fixture for the process of chip back of the body gold.
Background technology
For the chip kind that supply is larger, consider from cost and working (machining) efficiency, chip supplier is generally direct carries on the back gold process to complete wafer, and then is polylith chip by wafer scribing; And for the less chip kind of some supplys, because the back of the body lsp request of client may be different, therefore chip supplier does not generally provide the service of back of the body gold, but go out after the chip of respective amount directly to consign to the buyer from scribing wafer, carry on the back gold voluntarily by the buyer; Problems existing is: owing to needing to be covered by chip sidewall with silicon materials when carrying on the back gold process, and the size of chip is less, and back of the body gold is very bothersome separately, and carries out Integral back gold to polylith chip and lack corresponding fixture and fix polylith chip.
Utility model content
For the problem in background technology, the utility model proposes a kind of fixture for the process of chip back of the body gold, comprise the chassis of silicon material, its improvement is: the upper surface on described chassis is provided with movable type frame; Described movable type frame is made up of L shape sheth, bar shaped frame bar and many bar shaped compartmentation strips; The downside of described L shape sheth is provided with multiple latch; Described chassis is provided with the jack mated with latch; The medial surface of described L shape sheth is arranged the gathering sill I of indent; The end face of described bar shaped frame bar one end is provided with guide finger I, and size and the gathering sill I of guide finger I form tight fit relation; The sidewall of the axial side of bar shaped frame bar is provided with gathering sill II, gathering sill I and gathering sill II measure-alike; The end face at described bar shaped compartmentation strip two ends is provided with guide finger II, and the size of guide finger II and gathering sill I and gathering sill II all form tight fit relation; Guide finger I on bar shaped frame bar is plugged on after in gathering sill I, the structure bodily form be made up of bar shaped frame bar and L shape sheth is as " Π " shape, the guide finger II at bar shaped compartmentation strip two ends is plugged in gathering sill I and gathering sill II respectively, and the region surrounded by L shape sheth, bar shaped frame bar and bar shaped compartmentation strip just forms the rectangle clamping district of a variable area; Described L shape sheth, bar shaped frame bar and bar shaped compartmentation strip all adopt silicon materials to make.
Principle of the present utility model is: the rectangle clamping district surrounded by L shape sheth, bar shaped frame bar and bar shaped compartmentation strip, its size can regulate, during use, first chip is piled up on the inwall of L shape sheth by matrix form, then with bar shaped frame bar and bar shaped compartmentation strip, chip matrix is clamped, just can carry out back of the body gold and operate (back of the body gold operation equipment needed thereby and process conditions thereof are all undertaken by existing technique); After adopting the utility model, very easily polylith small-size chips can be fixed, and rectangle clamping district area is adjustable, the chip that can adapt to varying number carries on the back golden demand, and can be different to chip size but the inhomogeneity chip that back of the body lsp request is identical carries on the back gold process simultaneously, significantly improve the back of the body gold treatment effeciency of chip after scribing.
Preferably, described many bar shaped compartmentation strips have different lengths, and the bar shaped compartmentation strip of often kind of length has many.After adopting this to improve, the area in rectangle clamping district can be made to regulate more versatile and flexible.
Preferably, described chassis is circular.
Preferably, described chassis is symmetrically arranged with two L shape sheths.
Advantageous Effects of the present utility model is: be convenient to the chip after to scribing and carry on the back gold process, convenient, practical, working (machining) efficiency is higher.
