Research and Simulation of LTE Technology in Manufacturing Metal Part

Abstract:

Laminated templates electro-deposition (LTE) is a new manufacturing technique aimed at a highly precise and low-cost fabrication of metallic structures through a number of planar template-patterned depositing. The ability to control deposit surface non-uniformity in each planar depositing has been proved a key to this technique. Correspondingly a 3D simulation for electrical field has been modeled using finite-element method in line with the real experimental conditions. The mapped contour of simulating proved the variedly distributed electrical field and basically match with experimental results. Three groups of LTE test by direct current, pulse and double-pulse current are introduced and assessed in term of their effect to improve uniformity. By comparison, pulse application, especially double-pulse offered a better deposit quality with optimized parameters including pulse width, frequency, working time and off time. A bulk of 10-15layers copper parts, section size 20mm×20mm and 4-6mm thick were produced using the modified parameters.
