Abstract
The utility model relates to a WBGA wire arc anti-touch pressing plate, which comprises a pressing plate body, wherein the middle of the pressing plate body is provided with a substrate matching part, and the left side and the right side of the pressing plate body are provided with connecting parts; a plurality of avoidance grooves are formed in the substrate matching part; this scheme is through the contact surface design that changes the clamp plate, at the part of clamp plate probably with the base plate contact, designs into the fluting design, fine gold thread and the risk of clamp plate contact of having avoided the routing product on the base plate to thoroughly solve the problem of the unusual indiscriminate line of gold thread.
Description
Technical Field
The utility model relates to a WBGA line arc prevents touching clamp plate belongs to integrated circuit processing technology field.
Background
The existing WBGA product can cause the middle part of the substrate to arch up due to the fact that the substrate is heated during routing after gold threads of the block product are routed, and the gold threads operating on the product can touch a pressing plate above the substrate at the moment to cause abnormal disorder of the gold threads, so that short circuit of the product is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the deficiency of the prior art and providing a novel pressing plate which can thoroughly solve the problem that the material touches the wire arc in the stepping process.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a WBGA (work group grid array) wire arc touch-proof pressing plate comprises a pressing plate body, wherein a substrate matching part is arranged in the middle of the pressing plate body, and connecting parts are arranged on the left side and the right side of the pressing plate body; the substrate matching part is provided with a plurality of avoiding grooves.
Preferably, dodge the groove and set up along the width direction of clamp plate body, many dodge the groove and be parallel to each other and equidistant setting.
Preferably, the shape of the cross section of the avoidance groove is a trapezoid with a narrow lower part and a wide upper part.
Preferably, the connecting part on one side of the pressing plate body is provided with a waist hole, and the connecting part on the other side of the pressing plate body is provided with a positioning hole.
Preferably, the pressing plate body is of a flat plate structure, the left side and the right side of the pressing plate body are bent upwards to form connecting portions, and the connecting portions are lug plate structures parallel to the pressing plate body.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
this scheme is through the contact surface design that changes the clamp plate, at the part of clamp plate probably with the base plate contact, designs into the fluting design, fine gold thread and the risk of clamp plate contact of having avoided the routing product on the base plate to thoroughly solve the problem of the unusual indiscriminate line of gold thread.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
fig. 1 is a schematic view of a WBGA wire arc anti-touch pressing plate according to the present invention;
3 fig. 3 2 3 is 3 a 3 sectional 3 view 3 taken 3 along 3 line 3 a 3- 3 a 3 of 3 fig. 3 1 3. 3
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, a WBGA wire arc touch-proof pressing plate, contain pressing plate body 1, pressing plate body 1's centre has base plate cooperation portion 2, pressing plate body 1's the left and right sides has connecting portion.
The clamp plate comprises a clamp plate body 1 and is characterized in that the clamp plate body 1 is of a flat plate structure, the left side and the right side of the clamp plate body 1 are bent upwards through metal plates to form connecting portions, the connecting portions are of lug plate structures parallel to the clamp plate body 1, waist holes 4 are formed in the connecting portions on one side of the clamp plate body 1, and locating holes 5 are formed in the connecting portions on the other side of the clamp plate.
Offer many on the base plate cooperation portion 2 and dodge groove 3, dodge groove 3 and set up along the width direction of clamp plate body 1, many dodge groove 3 and be parallel to each other and equidistant setting, dodge the cross-sectional shape of groove 3 and be narrow down and go up wide trapezoidal.
In this scheme, the base plate is heated because the hot plate during the routing, the base plate mid portion that causes arches, can't solve this phenomenon through present existing technology, and 4 millimeters in total of the clamp plate height, the base plate arches 1 millimeter and can touch the clamp plate back, then with the design of slotting in the middle of the clamp plate back, the high 2 millimeters of slotting, can be complete avoid gold thread and clamp plate back contact, when having solved the base plate at the inside step-by-step of machine, the possibility of good gold thread and clamp plate contact of beating, the risk of product short circuit has been prevented, the bad production of product has been avoided.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
