Abstract: A MEMS vapour bubble generator that uses a heater in thermal contact with a liquid to generate a bubble. The heater is energized by an electrical pulse that is shaped to have a relatively low power, sub-nucleating portion and a high power portion that nucleates the bubble. The thermal energy transferred to the liquid by the sub-nucleating portion speeds up the nucleation of the bubble across the surface of the heater during the nucleating portion. This produces larger, more stable bubble having a regular shape.

Abstract: A compression bonding device has a dam member so that when a pressing head is pressed against an object to be pressed, the bonding part is surrounded by the dam member. Thus, even if the surface of the bonding part bulges by pressing, the bulging part is stopped by the dam member and the surface of the bonding part does not horizontally extend. As a result of the absence of horizontal extension of the bonding part, electric components of the object to be pressed are not subjected to a force that horizontally moves the electric components and the electric components are vertically pressed downward and connected to the terminals of the substrate. Thus, an electric device having high connection reliability is obtained.
