Description

Direct insertion type packaging support structure

Technical Field

The utility model relates to a semiconductor package structure, especially a formula of cuting straightly encapsulation supporting structure.

Background

In the TO/ITO series products of the electronic components packaged in a direct insertion manner at the present stage, the strength of a plastic package body is limited, the plastic package body of the whole support is easy TO damage in the production process of cutting pins, and partial devices cannot be shared, so that the equipment cost and the maintenance cost are increased.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a formula encapsulation supporting structure cut straightly in order to overcome among the prior art formula encapsulation structure's support pin structure easily to arouse the damaged technical problem of plastic-sealed body.

The utility model discloses an above-mentioned technical problem is solved through following technical scheme:

the utility model provides a cut straightly formula encapsulation supporting structure, the support includes main part and pin group, the main part side is extended through the splice bar and is formed pin group, pin group includes three first pins, second pin and the third pin of arranging side by side, wherein be located in the middle of the third pin with it has pre-compaction V type groove to dispose on the splice bar between the main part.

Preferably, the opening angle of the V-shaped groove is 50-60 degrees, and the depth is 0.05-0.07 mm.

Preferably, a pair of prepressing V-shaped grooves are arranged on the connecting ribs.

Preferably, the pre-pressing V-shaped groove is disposed at a connection position of the connecting rib and the third pin.

The beneficial effects of the utility model reside in that, can reduce the joint strength who cuts off the position for cut off the required intensity of support and far be less than the ruptured intensity of body, thereby avoid the body to break.

Detailed Description

The embodiment provides a direct plug-in package support structure, as shown in fig. 1, the support includes a main body 1 and a pin group 2, the main body 1 extends to form the pin group 2 through a connecting rib 3 side, the pin group 2 includes three first pins 21, second pins 22 and third pins 23 arranged side by side, wherein the third pin 23 located in the middle and the connecting rib 3 between the main body 1 are disposed with a pre-pressing V-shaped groove 4.

Specifically, encapsulation supporting structure is arranged in the prefabricated construction of cut straightly formula encapsulation support production process, and the formula encapsulates unnecessary part and the third pin 23 of muscle 3 that will amputate in the support production process, obtains as shown in figure 4 packaging structure, and wherein the encapsulation of support main part 5 is in plastic-sealed body 5, and first pin 21 and second pin 22 stretch out plastic-sealed body 5, through the V type groove on the muscle 3 between third pin 23 and main part 1, can amputate easily in the production process third pin 23, and can not lead to plastic-sealed body 5 damaged.

As one way to realize this, as shown in fig. 2 and fig. 3, the opening angle of the V-shaped groove 4 is 50 to 60 degrees, and the depth of the groove body is 0.05 to 0.07mm.

Specifically, the opening angle of the V-shaped groove 4 and the depth of the groove body influence the fracture threshold of the V-shaped groove, and if the strength of the V-shaped groove 4 is too high, the force required by fracture of the V-shaped groove exceeds the fracture strength which can be borne by the bracket body, so that the bracket body fractures; if the strength of the V-shaped groove 4 is too low, the V-shaped groove is very easy to break, and the connection strength at the cut-off position cannot be reduced.

For example, when the depth of the V-shaped groove 4 is 0.03mm, the fracture strength of the opening angle of the V-shaped groove 4 is 50 to 90 degrees, which causes the fracture of the stent body; when the depth of the V-shaped groove 4 is 0.12mm, the fracture strength of the opening angle of 50-90 degrees is too low, and the connection strength of a cutting position cannot be realized; when the depth of the V-groove 4 is 0.07mm, the opening angle thereof is 90 degrees, and the V-groove may be deformed and not broken during cutting.

As a way of realisation, the tie bars 3 are provided with pairs of pre-pressed V-grooves 4.

The V-shaped grooves 4 arranged in pairs can improve the success rate of fracture, avoid the condition that the deformation of the V-shaped grooves 4 causes the fracture failure, and improve the yield of products.

As a way of realization, the pre-pressing V-shaped groove 4 is disposed at the connection of the connecting rib 3 and the third pin 23.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
