Abstract
The utility model provides a LED inverts support, includes the support body and locates positive bonding pad and negative electrode bonding pad on the support body, positive bonding pad and negative electrode bonding pad surface all are equipped with the drainage groove. The utility model discloses a drainage groove has a guide effect, can be with each position of tin cream drainage to pad, when the electrode combines with the pad, distribution that the tin cream just can be even the faying face everywhere, reduce the welding voidage, in addition, the drainage groove is equivalent to the storage tank that sets up on the pad, can the unnecessary tin cream of holding, and when the weight of tin cream is too much, behind the tin cream on flip -chip LED's the electrode extrusion pad, because the drainage groove provides sufficient accommodation space for the tin cream, so the tin cream is can not the milli irregular to diffusion all around, but meets each other the elder generation and get into the drainage inslot, so can prevent that the tin cream from overflowing.

Description
Technical field
The utility model relates to LED field, especially a kind of LED upside-down mounting support.
Background technology
LED upside-down mounting support comprises rack body and the positive terminal pad be located on rack body and negative terminal pad, and the bottom of flip LED is provided with positive electrode and negative electrode, and the positive electrode of flip LED is corresponding with positive terminal pad, and negative electrode is corresponding with negative terminal pad.During flip LED die bond, positive terminal pad and negative terminal pad put tin cream, then flip LED is attached on pad.Because the component on tin cream drippage pad can not be accurate, sometimes often cause the tin cream component of drippage too much or very few, when the component of tin cream is too much, due to the electrode of flip LED and the contact-making surface out-of-flatness of pad, cause too much tin cream can overflow from the faying face of the two, the tin cream skewness of the faying face of electrode and pad, affects die bond quality; When the component of tin cream is very few, cause the cavity of die bond more.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of LED upside-down mounting support, and after electrode can be prevented to be combined with pad, tin cream overflows, and the tin cream of the two faying face can be made to be more evenly distributed.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of LED upside-down mounting support, comprises rack body and the positive terminal pad be located on described rack body and negative terminal pad; Described positive terminal pad and negative terminal pad surface are equipped with drainage trough.Drainage trough of the present utility model is equivalent to the storage tank arranged on pad, can accommodating unnecessary tin cream, when the component of tin cream is too much, after tin cream on the electrode extruding pad of flip LED, because drainage trough provides enough spatial accommodations to tin cream, so tin cream can not be irregular to surrounding diffusion in the least, but first enter in drainage trough, so can prevent tin cream from overflowing; In addition, drainage trough has guide effect, tin cream can be drained to each position of pad, electrode and pad in conjunction with time, tin cream just can be evenly distributed in faying face everywhere, reduces welding voidage.
As improvement, described drainage trough is cross, comprises cannelure and transverse groove.
As improvement, the intersection of described cannelure and transverse groove is positioned at the center of pad.
As improvement, the two ends of described cannelure extend to the two ends of pad longitudinal direction, and the two ends of described transverse groove extend to the two ends of pad transverse direction.
As improvement, described drainage trough is in-line.
As improvement, described drainage trough is M shape.
The beneficial effect that the utility model is compared with prior art brought is:
Drainage trough of the present utility model has guide effect, tin cream can be drained to each position of pad, electrode and pad in conjunction with time, tin cream just can be evenly distributed in faying face everywhere, reduces welding voidage; Drainage trough is equivalent to the storage tank that arranges on pad in addition, can accommodating unnecessary tin cream, when the component of tin cream is too much, after tin cream on the electrode extruding pad of flip LED, because drainage trough provides enough spatial accommodations to tin cream, so tin cream can not be irregular to surrounding diffusion in the least, but can first enter in drainage trough, so can prevent tin cream from overflowing.
Accompanying drawing explanation
Fig. 1 is embodiment 1 drainage trough structural representation.
Fig. 2 is embodiment 2 drainage trough structural representation.
Fig. 3 is embodiment 3 drainage trough structural representation.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
Embodiment 1
