    摘要: Methods and systems for forming a displacement scale comprising TIR prisms on a substrate are described. A system for forming the displacement scale includes one or more rollers having a pattern of total internal reflection (TIR) prism features in negative relief. As the rollers are rotated, the scale is formed on the substrate. The rollers may also include pattern features in negative relief. Rotation of the rollers simultaneously forms the displacement scale and the pattern features on the substrate. The TIR prism features of the displacement scale may be oriented to provide measurement of one or more of lateral displacement, longitudinal displacement and angular displacement.

    摘要: A process by which molten solder is purified in-situ, making the soldering process more efficient and yielding better results, particularly for lead-free soldering. Lead-free solder becomes practical for use since the temperature for reliable soldering is reduced. A layer of active additive is maintained on the surface of molten solder for scavenging metal oxide from the solder and assimilating metal oxide into a liquid layer. The active additive is an organic liquid having nucleophilic and/or electrophilic groups. As an example, a layer of dimer acid maintained on a wave soldering apparatus scavenges metal oxide from the bath, and assimilates dross that may form on the surface. Scavenging metal oxide cleanses the bath and lowers viscosity of the solder, and PC boards or the like soldered on the wave have reliable solder joints.

    摘要: A calibration system for a rotary encoder comprises a rotary encoder disposed on a manufacturing substrate, the rotary encoder including an encoder pattern. The calibration system also includes a calibration pattern written onto a surface of the substrate, the calibration pattern comprising a ring that includes a grating pattern, where a radial position of the grating pattern corresponds to an error value of the position of the encoder pattern. A method of calibrating the errors of a rotary encoder and a method of fabricating a high resolution rotary encoder on a surface of a manufacturing substrate are also provided.
