The lead frame and the crystal grain are firmly combined with each other by silver glue or tape. Zeng Figure 1 is a schematic diagram of the main mechanism of a conventional die-bonding machine. The substrate 5 is loaded by the feeding end on the left side of the conveying V-track 19, and a plurality of substrates 5 sequentially loaded are conveyed from the feeding jaws 17 to the discharge end of the conveying guide 19. The substrate 5 passes under the adhesive cylindrical container 8 and the dispensing head 9, and the adhesive in the container 8 is discharged through the dispensing head 9 to the units on the substrate 5. In addition, the pick-and-place mechanism sequentially takes the die 1G on the wafer 15, and the wafer 15_ is fixed on the film, and the film is stretched by the expansion mechanism 12 to form the die (7): Pull open. The die 1 () picked up by the pick-and-place mechanism u is moved to the wheel end and moved downward until the die (4) is fixed on the substrate 5, and the die 10 is fixed on the substrate β and the geochemistry is more < Daytime, big: Fit = area of the grain 10 is more time to squeeze the ground out. If the glue is changed to the poly-bundle = the band, then each die 10 needs more time, about the need. / can effectively combine the die 10 and the substrate 5, so it is obvious that the die 1327344 pressure: the process will become The bottleneck action of the conventional die-bonding machine, that is, the hourly production per h〇ur; UPH) will be affected and reduced. When using tape = grain 1 〇 with substrate 5, the output per hour is even less than 1200. In addition to the uninterested yield of the single-grain machine, ^17 is seriously tested by the problem of substrate distortion. Especially when engaged in the day (4) loading (four) "called _ one; batching, the thin substrate 5 will be affected by the chess baking temperature after the first die of the adhesive. The feeding jaws 17 are relays. The mode is alternately transmitted to the discharge end, and the warping of the substrate 5 often causes the feed jaws 17 to fail to correctly wire when the hand is changed, thereby causing collision between the substrate 5 and the conveyance guide 19, and even the die 10 on the substrate 5 Scratches or crystal collapses need to be scrapped. In summary, the packaging equipment market needs a device that can significantly increase the output per unit time of the semiconductor 2 with a thousand conductors and also reduce the die bonding process. SUMMARY OF THE INVENTION The object of the present invention is to provide a device for bonding a semiconductor wafer by using a multi-track feeding and a wheel lead frame or a substrate, and simultaneously adding a lead frame or a substrate. Therefore, by performing the die-bonding operation by alternately between the multiple transfer lines, the waiting time of the substrate temperature rise can be effectively saved, thereby increasing the early time production of the device. Another object of the present invention is to provide a pre-preparation. What? The die-bonding device for pressing the grain function in the step of pressing the main waste combination module of the post-pressing pressure includes a plurality of prosthetic heads and can simultaneously press a plurality of crystal grains to fully integrate with the substrate, so that it can be '6 - 1327344 Effectively increasing the unit time yield of the device. The other object of the present invention is to provide a die-free device that does not have a transfer transfer action, which can avoid jamming or interference during the substrate transfer process, and the present invention discloses an adhesive semiconductor. The wafer is used for bonding a semiconductor wafer to a package of a package carrier: the package carrier comprises a substrate or a lead frame. The device comprises a first material conveying unit, a second feeding conveying unit and a pre-pressing module. And a main dust-collecting module, wherein the first feeding conveying unit and the second feeding conveying unit are arranged to transfer the substrate to the pre-module module. The pre-pressing module will rely on the plurality of body wafers The sequence is placed on the surface of the substrate that has been sent to the substrate or the surface of the substrate that has been fixed on the substrate, and a force is applied to initially combine the semiconductor wafer with the substrate. Then, the plurality of heads in the main dust-collecting module are the same. The plurality of semiconductor wafers are touched and the plurality of semiconductor wafers are tightly bonded to the substrate or the fixed crystal grains. [Embodiment] FIG. 2 is a perspective view of the device for adhering a semiconductor wafer of the present invention. The material conveying module 29, the pre-pressing module 24 and the main pressing module 25. The material conveying module 29 includes at least a first feeding conveying unit 291 and a second feeding conveying unit 292, the two conveying units (the invention) It is not limited to two transport units, and the plurality of transport units are also claimed in the present invention. The base wheel transports the substrate 80 or the lead frame to the pre-press module 24. When the first feed transport unit 291 and the second feed transport One of the units 292 is initially fixed and fixed between the pre-pressing module 24 and the die, while the other has been turned to the left feeding end to carry the lower-sheet substrate 8. . The module 24 sequentially bonds a plurality of dies to the substrate 8 〇 action 8, and the transport unit carrying the next substrate 8 可 can perform heating of the substrate. Thus, by performing the die-bonding process alternately between the multiple transfer lines, it is possible to increase the waiting time of the substrate temperature rise, thereby increasing the unit of the device: the inter-production. Since the first feed transfer unit 291 or the second feed transport unit 92 directly transfers the substrate (9) to the pre-press module, the material that is not transferred by the parent may cause cutting or interference, and is particularly suitable for A thin or large substrate with a large amount of music is 8 inches. In the pre-pressing module 24, the pick-and-place mechanism 241 sequentially picks up the crystal grains on the wafer, and the wafer is fixed on a film, and the film is stretched by the expansion module 27 to separate the crystal grains from each other. Stretch out. The die picked up by the pick-and-place mechanism 241 is moved to the end of the transport guide 19 and moved downward until the die is fixed to the surface of the substrate 8 on the first feed transport unit 291 or the second feed transport unit 292. Since the main splicing module 25 can complete the sufficient bonding between the die and the substrate 8 , the pick-and-place mechanism 241 only needs to initially fix the die on the surface of the substrate 80 , that is, the die in the next transfer operation. There is no relative displacement between the substrate and the substrate. It does not take too long to become a production bottleneck compared to the prior art. Above the expansion module 27, a wafer vision unit U can confirm the position and angle of each die on the expansion module 27. The pre-pressing visual module 22 is disposed on the route of the first feeding and conveying unit 291 and the second feeding and conveying unit 292, and can confirm the position and angle of the front substrate 8 or the substrate 80. Whether the unit has a bad mark. After the pre-pressing module 24 preliminarily fixes the die, the substrate 8〇 is directly sent under the 1327344 main pressing module 25, or passes through the transfer conveying unit 293 to move the substrate 80: the die to the plurality of pressing heads 251. At the position of -254, the pressure heads 25 1 - 254 are then applied with appropriate force on the surface of the die, whereby the corresponding die can be sufficiently bonded to the substrate 8 . As shown in Fig. 3, in order to enable the invention to be more widely applied to multi-die packages or the actual production requirements of the substrate to be placed in the bomb s,

At this time, the second feeding and conveying unit condition has carried and heated a substrate, and the substrate that has been properly heated is transferred to the pre-position after the substrate is delivered to the transfer conveyor.
