Description

銑刀之結構改良 Structural Improvement of Milling Cutter

本創作係有關於一種銑刀之結構改良,尤指一種藉由複數刃面之其中一側具有高度較高的一第一高度,並以較高的該第一高度為中心順時針逐次遞減該些刃面高度的一第二高度、一第三高度、一第四高度、一第五高度、一第六高度及一第七高度,透過該些刃面高度的逐次遞減以降低銑刀於對一預設電路板加工時與夾持該預設電路板之一機台共振幅度,並藉由上述構建達到控制銑刀切削過程中不會產生多餘的毛邊、殘屑,並提升鑽孔作業的良率。 This creation is related to the structural improvement of a milling cutter, especially a kind of a first height that has a higher height on one side of a plurality of blade surfaces, and the higher first height is taken as the center to gradually decrease the clockwise A second height, a third height, a fourth height, a fifth height, a sixth height and a seventh height of the heights of the facets, through which the heights of the facets are successively decreased to reduce the accuracy of the milling cutter. A preset circuit board is processed with a resonance amplitude of a machine that holds the preset circuit board, and through the above construction, it is possible to control the cutting process of the milling cutter without generating excess burrs and debris, and to improve the drilling operation. Yield.

按,現今電子產品為朝向輕薄短小的設計趨勢下,使得各種電子產品對於體積要求變得更小,因此電子產品內部各種電子元件的製造加工將變得越來越精細,並使電子產品中可供電子元件組設定位之印刷電路板體積亦必須隨之縮小,所以在印刷電路板的製程中,大多會利用鑽頭或微型銑刀來進行孔洞加工,而可提供電子元件的複數接腳穿插後再予以焊固形成電性連接。 According to the current trend of electronic products towards light, thin and short design, the volume requirements of various electronic products become smaller, so the manufacturing and processing of various electronic components inside electronic products will become more and more refined, and make the electronic products can be used in electronic products. The volume of the printed circuit board for setting the position of the electronic component group must also be reduced accordingly. Therefore, in the process of the printed circuit board, drills or micro-milling cutters are mostly used for hole processing, and the plurality of pins that can provide electronic components are interspersed. It is then soldered to form an electrical connection.

再者,印刷電路板、IC載板等為了降低生產的成本,均會採用多層疊板同時加工,以配合電子元件構裝的小型化及陣列化,促使印刷電路板也不斷的提高佈局密度及層數以因應需求,於是便有業者研發出 高密度連接板(HDI板),具有體積小、速度快、頻率高的優勢,而廣泛的被使用在個人電腦(PC)、筆記型電腦(NB)、智慧型手機(Smart phone)及個人數位助理(PDA)上,並且使用上的需求有越來越輕薄的趨勢,因此也相對提高了現行銑刀於鑽孔加工上之困難,其最大的問題是鑽孔加工後的孔洞周圍會產生大小不一的銅箔外翻的情況。 Furthermore, in order to reduce the production cost of printed circuit boards, IC substrates, etc., multi-layered boards are used for simultaneous processing, in order to cooperate with the miniaturization and arraying of electronic components, and promote the continuous improvement of the layout density of printed circuit boards. The number of layers to meet the needs, so some companies have developed High-density connection board (HDI board) has the advantages of small size, high speed and high frequency, and is widely used in personal computers (PC), notebook computers (NB), smart phones (Smart phone) and personal digital Assistant (PDA), and the demand for use has a trend of becoming thinner and lighter, so it also relatively increases the difficulty of the current milling cutter in drilling processing, the biggest problem is the size of the hole around the hole after drilling processing. Different copper foil eversion.

由於一般的銑刀為了減小軸向鑽孔的軸向力,所以銑刀的刀心設計上通常很薄,並由圓心向外逐漸增厚,且二刀刃的邊緣處厚實,其旋轉切削的能力就很強,即可適用於鑽削作業,不過因電路板的厚度越來越薄,電路板利用習知銑刀進行鑽孔時與該電路板之夾持機台易產生共振現象,如此便無法控制鑽削孔洞的均勻性,導致鑽孔作業的良率降低,即為有待從事於此行業者所亟待研究改善之方向所在,即為有待從事於此行業者所亟欲研究改善之關鍵所在。 Because the general milling cutter is designed to reduce the axial force of the axial drilling, the cutter center of the milling cutter is usually very thin, and gradually thickens from the center of the circle to the outside, and the edge of the two cutting edges is thick, and its rotary cutting The ability is very strong, and it can be suitable for drilling operations. However, because the thickness of the circuit board is getting thinner and thinner, the circuit board is prone to resonance with the clamping machine of the circuit board when the conventional milling cutter is used for drilling, so it is impossible to Controlling the uniformity of drilled holes and reducing the yield of drilling operations is the direction that needs to be studied and improved urgently by those engaged in this industry, which is the key point that needs to be studied and improved urgently by those engaged in this industry.

故,創作人有鑑於上述之問題與缺失,乃蒐集相關資料,經由多方評估及考量,並以從事於此行業累積之多年經驗,經由不斷試作及修改,始設計出此種具有防塵及降噪功能之按壓開關新型專利誕生。 Therefore, in view of the above problems and deficiencies, the creator collected relevant information, evaluated and considered from various parties, and based on years of experience accumulated in this industry, through continuous trials and revisions, before designing this kind of dustproof and noise reduction. A new patent for functional push switch was born.
