Abstract: In a method of assembling an electronic component onto a substrate, a fiducial is defined by a solder mask positioned upon the substrate. A fiducial-defining window in the mask has a base of the window completely provided with a material of different light-reflecting quality than the mask surface. This provides for the peripheral edge of the window, i.e. the mask, to be the edge of the fiducial. Windows in the mask which expose terminal pads upon the substrate and fixed in position relative to edges of the fiducial and both these windows and the fiducial are determined by the mask. Surface mount components are then located upon the substrate relative to the window positions and not relative to the terminal pad positions. This process reduces the number of incorrect connections of terminals of components to terminal pads.

Abstract: An apparatus is disclosed for temporarily attaching a pre-atomization bowl to a wall of a generally annular combustion chamber during assembly of the combustion chamber with the fuel injector assembly. The attachment apparatus holds each of the pre-atomization bowls in a position so as to minimize the stress imparted to the fuel injectors during assembly of the engine components. The apparatus utilizes a magnetic attachment device to hold the pre-atomization bowls in their assembly positions. The force of the magnetic attachment device is sufficient to hold the pre-atomization bowls in these positions against the effect of gravity, but is insufficient to prevent the radial movement of the pre-atomization bowls relative to the combustion chamber once the turbojet engine has been assembled. Thus, the device does not inhibit the radial play of the pre-atomization bowls once the engine has been asssembled.

Abstract: A ring sizer which closely conforms to any ring shape thereby permitting correct sizing of a ring being measured. At least the surface portions of the ring sizer are elastic and adapted to distort locally to the extent necessary for complete conformity with the inner surface of a ring placed thereon and in frictional contact therewith.

Abstract: A ring sizer includes a handle assembly which rotates about a post with first roller and gear mounted on the post to cooperate with a second roller and gear on the handle assembly. A rotatable handle on the handle assembly moves the second roller and gear towards the first roller and gear. A pair of keeper pins on the handle assembly hold a ring on the first roller while the second roller exerts pressure on the ring shank to lengthen it. A groove in the second roller matches the cross-section of the ring shank to eliminate stretch marks and marring on the ring shank. The ring has a shank with a thick portion diametric to the jewel portion. The method of using a ring sizer calls for tightening the grooved roller adjacent the non-thick portions of the shank, so that no dents are caused in the shank. Beveled edges in the shank eliminate stretch marks and sharp edges during sizing.
