When the conducting resin structure is used, the conductors are in contact with the electrodes of the PCB to increase press-down stroke, so as to prolong the service life of the conducting resin and reduce solder splash falling on the surface of the conducting resin; meanwhile, the contact between a chip and the PCB of the detection device are more stable, and loose contact is prevented.
Description
Technical field
The utility model is about a kind of conducting resinl structure, be meant that especially a kind of use is when the detection of the chip of solder ball array encapsulation (BGA), can increase to press down stroke and alleviate and press down strength, and make the more stable conducting resinl structure that contacts between the printed circuit board (PCB) (PCB) of chip to be measured and a checkout gear.
Background technology
Along with science and technology is constantly progressive, various electronic product is constantly weeded out the old and bring forth the new, also bring simultaneously people's many facilities in life and efficient, more because various electronic product has occupied indispensable role at present in life, therefore, the stability of electronic product more allows the people pay attention to, since at present electronic product mainly by circuit board and on it cooperatively interacting of chip form, make the chip stability on the circuit board come into one's own more, in the process of present various chip manufacturing, because yield still can't reach absolutely, therefore after finishing, manufacturing still needs bad chip screening to be gone out by inspection process, and make it be able to the product condition of poor and take place.
At present in chip screening and measurement, main by a conducting resinl 1, see also shown in the 1st figure, this conducting resinl 1 is provided with the cushion compound 11 of an insulation, be provided with many conductive metal wires 12 in this cushion compound 11, each conductive metal wire 12 is arranged in this cushion compound 11, and each conductive metal wire 12 one on contact jaw 121 and once contact jaw 122 (two ends) is protruding respectively exposes on this conducting resinl 1, lower surface, use printed circuit board (PCB) 22 (PCB) for contact one a chip (not shown) to be measured and a checkout gear, make this chip to be measured be able to be electrically connected, detect with the printed circuit board (PCB) 22 of this checkout gear.
During use, the solder ball array encapsulation (BGA) of this chip to be measured is positioned over last contact jaw 121 tops of this conducting resinl 1, and following contact jaw 122 belows that the printed circuit board (PCB) 22 of this checkout gear placed this conducting resinl 1, by pressing down this chip to be measured this chip to be measured is electrically connected via the printed circuit board (PCB) 22 of this conducting resinl 1 with this checkout gear, and can carries out the detection of this chip to be measured.
Yet, though this known conducting resinl 1 can carry out the detection of this chip to be measured, but it utilizes conductive metal wire 12 directly the tin ball and the printed circuit board (PCB) 22 of this chip to be measured of contact, because tin ball circle is not easy contact, need to use the bigger strength that presses down, just can make the complete contact conductive metal wire 12 of chip to be measured, so thorn contact that scruff is exerted oneself because of conductive metal wire 12 easily on the tin ball, and scruff drops (thorn falls) on the conductive metal wire 12 of this conducting resinl 1, need are often cleared up otherwise are easy to generate loose contact, very not convenient, and use big under amount of pressure also cause cushion compound 11 bendings of conducting resinl 1 easily and elastic fatigue reduces useful life.
This shows that above-mentioned existing article still have many disappearances, real non-one kindhearted design, and demand urgently being improved.
