Abstract: Fine particles which electrostatically adhere to synthetic resin pellets are separated from the pellets by bringing the pellets/fine particles mixture into contact with an ionized gas. The ionized gas eliminates the electrostatic adhesion between the synthetic resin pellets and the fine particles. The resulting fine particles may thereafter be readily separated from the pellets and the freed fine particles may be withdrawn in a gas stream. Removal of the fine particles to less than 40 ppm is possible. Apparatus for carrying out the method is also described as is a system for stocking synthetic resin pellets using the described apparatus.

Abstract: An integrated circuit package, and a method for forming the integrated circuit package, including a single layer or multilayer substrate in which interconnection vias are formed is described. Laser energy is swept across a surface of a mask in which holes have been formed. Laser energy passing through the holes of the mask forms vias in a substrate held in place below the mask. The laser energy is swept at such a speed and is maintained at such an energy level that the laser energy forms vias in the substrate, but does not penetrate a set of leads attached to the substrate. Vias may be formed in this way by either a mask imaging, contact mask or conformal mask technique. The laser energy is emitted from a non-thermal (e.g., excimer) laser. The substrate is formed of an organic (e.g., epoxy) resin. The resin may include reinforcing fibers (e.g., aramid fibers). Substrates may be formed on one or both sides of the set of leads.
