MICRO THROUGH-HOLE FORMING DEVICE, METHOD OF MANUFACTURING MICRO THROUGH-HOLE FORMED PRODUCT, AND MICRO THROUGH-HOLE FORMED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a micro through-hole forming device capable of easily and efficiently forming many micro through-holes on a sheet of synthetic resin in a simple manner and in a short time, and at that time, preventing the occurrence of the deflection of a preform.;SOLUTION: A micro through-hole forming device 10 includes a supporting base 11, a back sheet 12 for supporting a preform 20, and an ultrasonic form block 30 which is arranged above the back sheet 12 and has many projections 31 at a lower part. Flat load imparting regions 39 and 28 are provided around a projection forming region 34 of the ultrasonic form block 30 and around a protrusion region 11a of the supporting base 11, respectively. The ultrasonic form block 30 is movable vertically and made to ultrasonic-vibrate in the vertical direction to heat the preform 20 by vibration, and thus the preform 20 is melted to form many micro through-holes 41. At that time, a load is applied to the preform between the load imparting region 39 of the ultrasonic form block 30 and the load imparting region 28 of the supporting base 11.;COPYRIGHT: (C)2013,JPO&INPIT
