However, the size of the printed circuit board and the IC carrier must be reduced with the size of the electronic product, and in order to reduce the cost of manufacturing the manufacturing process, the multi-layered board is simultaneously processed, that is, the glass fiber and the epoxy are used. The resin multi-layer laminate is made in the table = intermediate press-bonded, and the printed circuit board and the IC carrier are produced using a dedicated M325180 U-type drill or milling cutter, and the micro-drill is a PCB and a BGA (spherical matrix). Carrier board) and other necessary materials in the production process of IC carrier board, and the cutting angle and chip removal problem during micro-drill processing will be the key to affect the quality of the drilling, if the micro 5L drill pin chute and hole If there are accumulated chips between the walls, the chips will block between the diamond needles and the wall of the hole and scrape each other, so that the surface of the micro-drill hole wall is thick, the accuracy of the processing operation is reduced, and the circuit board product is reduced. Yield; secondly, the micro-drilled pin-removal shaft is shouting and chip-discharging, and the wear and damage of the cutting part of the pin-shaped burr is also caused by the frictional resistance caused by the high-speed rotation of the machine. Its temperature rises rapidly, The effect is poor, together with copper protruding phenomenon of high-temperature chips produced hot melt glue> multilayer board is not checked and adhesion caused by the micro drill so prone to chipping or breaking. 4 See the sixth and seventh figures, which are the top and cross-sectional views of the conventional use. As can be clearly seen from the figure, the micro-drill A has a blade A1 and is outside the blade> A1. The cutting edge A 1 1 is formed at the end edge, and the cutting portion A 1 1 has a spiral groove A 1 2 toward the blade portion A, and a 77 A 1 interlocking at the cutting edge. The portion A 1 1 can be used to guide the debris through the chip flute A 12 by cutting the edge of the cutting portion A 1 1 to the wall of the predetermined working object, and to achieve the purpose of drilling. The spiral chip waste space formed by the drill needle A in the chip flute A 2 is ', that is, the contact groove A 1 2 is matched with the micro-pay pin a and has a certain groove width ratio design, and the row is a groove A 1 The groove width of 2 cannot be arbitrarily widened to prevent the structural strength of the micro-drill A as a whole from decreasing, and it is easy to pile up at the end portion of the A 1 2, so that the chip removal efficiency of the chip flute A i 2 is limited, and it is impossible to Immediately cut the 6 M325180 chips to remove them, even if the chipping chamber A丄2, the probability of blocking increases greatly, and it is easy to cause the ° product to be even 'will cause it to There are cracking or breaking, the use of 1 phase micro drill A consumables and the consideration of the process door. 07 Trace I does not pay for the economic benefits of the problem and lack of drilling needles, that is, the direction of doing this good, and the relevant industry is waiting to be related to how to solve the above-mentioned industry, the relevant manufacturers want to study and further improve and re-engineer The necessity of design [new content] The creators have designed the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The birth of the wealth. The main purpose of this creation is that the side of the thin handle - the extension of the blade, ^ outside the knife ___, _ knife ya _ extension is a spiral of the levy, borrowing __ micro, _ The groove can be formed with a large touch, the forest will shadow _ head overall ς = chip to increase the _ face, _ _ groove, will form at the touch =: guide groove of the chip flute '俾The guide groove can be increased by 2 degrees when the guide groove and the groove are increased, and the guide groove can assist the cutting object to rush out in the chip flute when drilling the preset work object. The wall of the Lai and Linwei crops is not easy to produce a pile-cutting situation, and the money is prevented from being scraped and the surface of the hole wall is scraped together. The surface quality of the drilling hole wall is smooth and accurate, and the M325180 preset is improved. The yield of the work. The secondary purpose of the creation is that the guiding groove can make the chip in the chip flute not easy to have a base and the chip is bad, and the bit cutting edge can be reduced when the bit rotates at a high speed. Wear and damage, and improve the service life of the drill bit, can also effectively reduce the temperature rise caused by excessive friction resistance and poor cooling effect, etc., which can prevent the chip from being caused by high temperature hot melt, or The copper protrusion caused by the preset work is not close, and the money is not allowed to crack or break. [Embodiment] In order to achieve the above purpose and structure, the technical means and its functions adopted by this creation, Zha Lai's hard work in this creation _ detailed addition of its steps _ Wei as follows, 俾利 fully understand. Please refer to the first four and five figures, which are respectively the three-dimensional external drawing of the creation, the partial enlarged view, the side view, the top view and the sectional view of the part A of the drawing. It can be seen that the drill bit structure improvement of the present invention includes a drill bit 1 composed of a shank portion 1 1 and a blade portion 12, wherein: the drill bit 1 has a blade portion 延伸 2 extending from one side of the shank portion 11 and outside the blade portion 12 The end edge forms a cutting edge 121, and the cutting edge 12 is extended to the inner side to be concavely provided with a spiral flute i 2 2 , and in the case of the wide flute i 2 2 , the groove shape is modified The u-shape is shaped to increase the chip evacuation space, which is recessed in the guide groove 123 of the chip flute in the drill tip.上述, the guiding groove 1 2 3 is the bottom of the spiral groove 1 2 2 of the drill bit i, and even the groove 丨 2 2 having a fixed groove width can form a row of 8 M325180 The chip space ' does not affect the overall structural strength of the drill bit i, and the squeegee can be increased through the guide groove 1 2 3 and the groove 1 2 2, and the drill bit is used to drill the preset work (Fig. When not shown, the guiding groove 丄2 3 can assist the rapid discharge of the cutting object in the chip flute 12 2 , and it is not easy to arrange the bit 丄 between the slot 2 2 and the hole wall of the pre-hybrid crop. When the accumulated chips are generated, the chips can be prevented from being clogged with the drill 1 and the holes and rubbed against each other, so that the surface quality of the face wall is smooth, the precision is good, and the yield of the preset work is improved. The preset work object is a circuit board with an electronic circuit such as a road board or an IC button, and the lead head 1 is arranged in the slot 1 by guiding the groove ^ 3 when the preset work is performed on the drilling process. In the case of 2 2, it is not easy to have a blockage or a poor condition. When the drill 1 is rotated at a high speed, the wear and damage of the cutter cutter 121 can be reduced, and the mesh can be improved. It can effectively reduce the temperature rise caused by excessive frictional resistance and poor cooling effect, and thus prevent the slag caused by high temperature hot melt or the copper protrusion caused by the preset work. Phenomenon, it is not easy to crack or break. The above-mentioned author's hard work of the shirt is based on the comparison between the hole position accuracy (C p K ) and the broken tail of the conventional micro-money needle, and the result is integrated.参 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 2.! 3, the needle break rate 〇 /! ◦◦, then in the right half of the figure can clearly see the micro-drill hole accuracy (CPK) is! · 9 8.
