People’s lives are always filled with technological products, such as computers, mobile phones, televisions and other electronic products. Most of these electronic products have printed circuit boards (PCBs). board) to control the operation of these electronic products, and the most common printed circuit boards are flexible circuit boards, mobile phone boards, ball grid array boards (BGA), DDR2 circuit boards, BOC (WBGA) package substrates, traditional printed circuit boards, etc.; and various circuit boards are set up to match various memories, and because the number and quantity of pins of various memories are different, and the size of the memory is small and the number of pins is large, the pin spacing of the memory is also different.
為此為了進行各式電路板的加工，利用銑刀進行加工的作業就變得更加重要，然而排屑的不良時常是銑刀上刀具損壞的一個重要原 因，該銑刀的刀身係於加工、切屑，時因排屑的不良而造成回彈作用致使刀具、刀身更容易折損，因此如何提供該銑刀的刀刃、刀身的排屑效率及流暢度，即為有待從事於此行業者所亟欲研究改善之關鍵所在。 In order to process various circuit boards, the use of milling cutters for processing becomes more important. However, poor chip removal is often an important cause of tool damage on the milling cutter. The blade of the milling cutter is used for processing and chip cutting. When poor chip removal causes rebound, the tool and blade are more likely to be damaged. Therefore, how to provide the chip removal efficiency and smoothness of the milling cutter's blade and blade is the key to be studied and improved by those engaged in this industry.
