Embodiment 1

[0043] refer to figure 1 and figure 2 , the configuration of the vacuum suction sheet 2 according to the first embodiment (Embodiment 1) of the present invention will be described. The vacuum suction sheet 2 of this embodiment is mounted and fixed on a metal base 3 in a fixing jig 1 for simultaneously cleaning and inspecting many electronic components that have been separated into pieces. being used. The vacuum suction sheet 2 is provided so as to cover the protruding surface 31 protruding from the upper surface of the base 3 .

[0044] The vacuum suction sheet 2 is formed by molding silicon-based resin or fluorine-based resin into a sheet shape, and accommodating portions 23 serving as spaces having shapes corresponding to target electronic components are formed in a grid pattern on the surface of the sheet. In the present embodiment, the housing portions 23 are separated from each other via the grid-like boundary 26, but the vacuum suction used when cutting the resin enc...

Embodiment 2

[0051] An enlarged perspective view of a fixing jig 1A equipped with a vacuum suction sheet 2A according to a second embodiment (Embodiment 2) of the present invention is shown in Figure 6 middle. In the vacuum suction sheet 2A of this embodiment, a hemispherical protruding portion 28 is formed on the bottom surface of the housing portion 23A. As far as the protruding part 28 is concerned, it should be as low as possible in consideration of the elasticity of the vacuum suction sheet 2A and the strength of vacuum suction, so that after the vacuum suction is started from the suction hole 24A, the protruding part 28 can be sucked in a short time. One surface of the sheet is pressed and buried therein. In addition, the protruding portion 28 may be in the shape of a polygonal pyramid, a polygonal column, a column, or the like.

[0052] For the use of the vacuum suction sheet 2A, refer to Figure 6 Be explained. When the electronic component 40 with the lower surface 41 flat is...

Abstract

The purpose of the present invention is to provide a vacuum suction sheet for a singulation device, whereby it is possible for singulated items to be reliably released from vacuum suction when the vacuum suction is released, and the singulated items reliably transported to the next process. This vacuum suction sheet (2), which comprises an elastic body having suction holes (24) for vacuum suction of singulated items (40), is furnished with protrusions (25) surrounding the suction holes (24). When the singulated items (40) are rested on the vacuum suction sheet (2) and vacuum suction is applied, the singulated items (40) are pressed against the protrusions (25), causing the protrusions (25) to elastically deform, increasing the contact area of the two. On the other hand, when the vacuum suction is released, the protrusions (25) return to original shape due to elastic resilience, pushing the singulated items (40) upward. At this time, due to the small contact area of the singulated items (40) and the protrusions (25), the singulated items (40) can be easily removed from the vacuum suction sheet (2).

Description

technical field [0001] The present invention relates to a vacuum adsorption sheet used in a fixing jig for absorbing and fixing singulated objects in a singulation device, and a manufacturing method of the fixing jig. Background technique [0002] A substrate is divided into a plurality of grid-like regions, and chip-shaped electronic components are mounted on each region, and then the entire substrate is resin-encapsulated, which is called a resin package. This resin-encapsulated body is cut with a rotary blade or the like, and is separated into individual pieces along each domain unit to form an electronic component. [0003] An apparatus for singulating a resin encapsulating body integrally encapsulating many electronic components to manufacture individual electronic components including each electronic component is a cutting process with the resin encapsulating body, obtained by the cutting process A plurality of manufacturing units corresponding to each process such as...
