Abstract: Embodiments of methods and apparatus for reducing warpage of a substrate are provided herein. In some embodiments, a method for reducing warpage of a substrate includes: applying an epoxy mold over a plurality of dies on the substrate in a dispenser tool; placing the substrate on a pedestal in a curing chamber, wherein the substrate has an expected post-cure deflection in a first direction; inducing a curvature on the substrate in a direction opposite the first direction; and curing the substrate by heating the substrate in the curing chamber.

Abstract: A cooling method for multi-axis controller includes a first step of enabling a first temperature sensor and a second temperature sensor to respectively detect the temperature of a first heat source and the temperature of a second heat source and to send the respective detected data to a control unit, and a second step of enabling the control unit to drive a first bi-direction fan to exhaust air if the temperature of the first heat source surpasses a predetermined upper temperature limit or to drive a second bi-directional fan to exhaust air if the temperature of the second heat source surpasses the predetermined upper temperature limit, thereby achieving enhanced cooling efficiency.

Abstract: A rotation drive device includes a crankshaft which has two ends dynamically connected to a drive source and a driven device, respectively. The drive source drives the crankshaft to rotate the driven device. The crankshaft structurally changes to make the two ends of the shaft portion connected to the rotation drive portion and the driven portion, respectively, at different central angles, which divides the space into two subspaces which are located two sides of the shaft portion, so that the wire can be arranged in the subspaces at both sides of the shaft portion, thus enhancing the flexibility of wire distribution while improving rotation range of motion.
