LE SHEET

A high-function entry sheet for mechanical drilling that achieves both improved quality/productivity of through hole work and extended drill bit life

LE SHEET is an auxiliary sheet for printed wiring board drilling with a water-soluble lubricant layer on an aluminum sheet (70-150μ). As an entry sheet for mechanical drills, it inhibits drill bit wear and enables extended drill bit life, while also having an effect of increasing through hole quality.Furthermore, it also enables the reduction of drilling costs by increasing the number of overlaid boards during through hole machining, and achieves a great increase in productivity.

Main Applications

  • As an entry sheet for mechanical drills in through-hole machining for printed wiring boards

Use Effect

  • Increased quality of through hole machining
    (Enables through holes with little inner wall roughness, plating soak-in, and smear generation)
  • Improved hole positioning accuracy
  • Enables through hole machining of multiple boards at the same time
  • Prevention of drill bit breakage/wear, extending the drill bit life
