A method of pre-applying a bolster assembly to an interior trim part includes the steps of applying a base skin layer to a groove of a first nest, applying a bolster skin layer to a second nest, positioning the first nest in an open position, and inserting a leading edge of a bolster skin layer in the groove of the first nest when the first nest is in the open position until the bolster skin layer engages the base skin layer. The bolster assembly can be attached to the interior trim part by a Foam-In-Place (FIP) or Low-Pressure Molding (LPM) operation. The interior trim part may comprise a dashboard garnish, an instrument panel (IP), a door panel, and the like. A boss locating portion can be integrally formed within the base skin layer and is used for locating the bolster assembly on the interior trim piece during the manufacturing process. Because the bolster assembly is pre-applied to the interior trim part prior to the FIP or LPM operation, the bolster assembly can be positioned at the bottom-most portion of the groove to provide a consistent fit and finish, while reducing scrap material and cost of the interior trim part.

The invention relates to a wafer detection device and method used for an ashing machine. The method includes: before a vacuum arm is used to transport a wafer which is processed in a reaction chamber, whether the wafer is broken is detected; infrared ray is firstly sent by an emitter to the surface of the wafer and if infrared ray reflected by the wafer can be received by a receiver, it proves that the wafer is not broken and then the vacuum arm is controlled to extend out into the reaction chamber to replace the wafer; and if the receiver cannot receive the infrared ray, it proves that the wafer is broken and then the vacuum arm is stopped from continuing to extend out. The wafer detection device and method are simple and reliable and capable of detecting conveniently the state of the wafer before the wafer is transported so that after the wafer is found to be broken, the vacuum arm can be stopped immediately from extending out into the reaction chamber and thus the number of scrapped wafers is reduced and the vacuum arm and lift pins in the reaction chamber are protected and the service life of the machine is prolonged.
