    Test Summary for the coating drills
    1.          Drill size : 0.3mm
    2.          Drill type: UCHA
    3.          Drill Length: 5.5mm
    4.          Test M/C: Hitachi Mark 30,
    5.          Entry material： 0.20mmaluminum sheet.
    6.          Backup material: 1.5mmphenolic board.
    		 *
    7.          Test board: PE test board, 8 layers, copper thickness 1/1, board thickness: 0.96+/-0.04mm
    8.          Drill hole parameter: normal
    9.          Drill hole condition: normal
    10.      Test board material: Mica. TG 140. (supplier: Doosan) inner core 3mil
    11.      Stack: 3 panels/stack
    12.      Lay-up instruction: (see attachment)
    Conclusion: 
    The performance of new drill bit (with yellow ring) is accepted.
    8000 life time for the new bit is recommend . 
    Remark: 40% of wear and tear of drill bit can be accepted when the first drilling.
