The combination of the pins of the electronic components and the printed circuit board is welded by the preset holes. The holes are formed by using micro drill pins, which are suitable for various printed circuit boards. Hole size requirements, there are different types of micro drills can be used, these print packages 3 ball point array (BG a) board, mobile phone board, flexible circuit board and traditional printed circuit boards. The left end of the % 14 and the general-type burr is the upper part, the right end is the drill part, and the micro-drill is used to drill the holes of various circuit boards. The better the ability to drill holes, the circuit board can be made. It's even smoother. Therefore, the geometric design of the drill bit and the choice of materials have become the key to determining whether the micro-drill is good or bad. In the selection of materials, materials that can withstand high-correction and high-order are usually selected, such as carbonized thieves. Choose it. However, the general micro-architecture structure is attached to the tip of the spiral to reduce the tip of the drill to the root of the root. The accuracy of the drill is better. The screw of the drill bit is 5 M351757 M351757 I, 1, \ The angle of the heel (he 1 1 X ang 1 e ) will be smaller, that is, the bit screw is steeper. This can make the drilling precision better when the drill bit is operated. However, the screw cutting part of (4) causes the hole between the hole and the hole wall. The frictional force (resistance) is greatly increased, and at the inter-speed operation, the temperature of the drill bit will be higher and it will be easy to break. On the other hand, in order to make the drill bit more suitable for high-speed operation and reduce the resistance when the head is operated, Quality, the helix angle of the drill bit (helix angl material: the thread cutting portion of the drill bit is flatter than the slope, but, conversely, such a punching portion is not conducive to drilling accuracy and reduces the performance of the operation. Therefore, how to try to solve the lack and inconvenience of the above-mentioned system is the one that the relevant proponents want to study the direction of improvement. Eight [new content] Therefore, the 'creator _ Yu Shang _ and the missing, the county details, By Guangfang Miscellaneous and Test 1, and to engage in this line (four) Years of experience, through the non-manufacturing and modification of the 'designed "drill face (four) turn" new patent born. Snail: τΓ^Γ The purpose is to the 77 head of the drill bit angle to the rear 2 angle The pre-expansion state 1 has a rear end helix angle minus the head end position 2 angle is less than i 5 degrees. When the drill bit is drilled, the small helix angle at the front end can increase the hole shavings along the tail end of the drill bit. The groove forms a slower and longer field to quickly open the hole, and achieves the effect of good contact effect and good quality of the hole wall. Embodiment] M351757 Λί<: Jingchong ijda provides the purpose and effect, the technology used in this creation :: The preferred embodiment of the present invention adds the following features and functions as follows: The full two-shower is the three-dimensional appearance of the creative bit and the side view is clearly seen 4 'this creator _ 1 micro-scho structure The shank portion 11 has a blade portion a extending therefrom and a cutting blade 121 is formed on the outer side of the blade portion 12, and the cutting blade 121 is turned inside: a spiral chip flute 122, and the center axis of the row member 22 and the blade portion 12 = angle ("11Χ angle"' and the tip end of the blade 12 is screwed to the rear end helix angle Θ 2 angle is The sequence forms a divergent and large state, and its rear end helix angle Θ 2 angle subtracts the head end helix angle 0 i angle 2◦ to 5 degrees to present less than or equal to 15 degrees. 俾当本作_!螺魏转In the section, in order to align the head end of the knives of the drill bit with the workpiece (the hole is not shown in the figure, the knives are at the end of the spiral angle θ 1 to the rear end helix angle 0 2 angle In order to gradually expand and expand into a large state (that is, the structure is slightly ugly and ugly, the spacing is short, and the angle is slow), in the process of gamma, the drilling system can be made along the drill bit 1 i 2 2 The discharge is made by the slowing of the chip removal slot 2 2, and the problem of the friction of the hole (four) is achieved, which has the effects of good chip removal effect, good hole wall quality and high drilling precision. By the way, the knives 12 of the drill bit 1 can pass through the slats 2 2 to achieve smooth chip discharge, and when the drill bit 1 is used to drill a red crop, the _! 排 丨 2 2 and the preset 7 M351757 If there is no accumulation of chips between the walls, the chips can be scraped between the drill bit 1 and the wall of the hole, so that the surface quality of the drilling hole wall is smooth, the precision is good, and the yield of the preset work is improved. i When the high-speed rotation is used, the wear and damage of the blade portion 12 of the drill 1 can be reduced, and the service life of the drill bit i can be improved, and the temperature rise due to excessive frictional resistance and the poor cooling effect can be effectively reduced. It can prevent the slag caused by the hot melt and the slag generated by the high temperature hot melt, or the premature work is not close together, which is not easy to cause smashing or breaking. The drill 1 described above can be applied to the manufacture of a printed circuit board (PCB) such as a ball point array (BGA) board, a mobile phone board 'flexible circuit board, and a conventional printed circuit board. Wherein the 'spiral angle is smaller in the spiral tip end of the drill bit i 2' and the spiral rear end flute 12 2 of the drill 1 is larger, the helix angle The end row of the groove 1 2 2 is <9 1 degree, and the rear side chip flute 丄 2 2 is 6 > 2 degrees.
