<p>PURPOSE:To remove molding material without injuring an inner matter by making dry distillation of the molding material composed of high-molecular substance being used as coating material. CONSTITUTION:Into an electric furnace heated at 400-430 deg.C is inserted a test tube 2 in which there is placed a matter 6 such as a semiconductor molded by high-molecular substance composed of thermosetting resin. A glass tube 3 is inserted near the bottom of the test tube 2, air is sent from the glass tube 3 at 20-30ml/min to make dry distillation of the high-molecular substance. Then, the molded matter is taken out and the high-molecular substance is removed by ultrasonic cleaning.</p> |
