Electrochemical finishing of nickel microstructures
One method to manufacture high aspect ratio metallic microstructures is the LIGA technique. The acronym LIGA stands for the German words for lithography, electroforming and moulding. A resist layer (e.g. PMMA) is structured using deep X-ray lithography. The resist is developed and the resulting mould is filled with metal by electroplating. Though electroplating is an essential part of the LIGA ...
متن کاملOptimizing Electrochemical Buffing Control Parameters for Surface Finishing of Ultrahigh Purity Components
Electrochemical buffing technology (ECB) applies electrochemical and mechanical finishing characteristics in the surface finishing process. ECB can buff ultrahigh purity components to make them shine, without leaving residual stress, micro-cracks, and etc. The control parameters of the ECB process include current density, the rate of revolution of the buffing head, the buffing pressure on the s...
متن کاملUltrasonic Cleaning and Surface Finishing
Careful preparation and cleaning of various types of components is indispensable prior to their surface treatment or final assembly. Various surface treatment operations that require such care include vacuum deposition, electrodeposition, electroless deposition, various dip coatings, etc. Surface preparation is essential for achieving good and firmly adhered coatings. Trace of residual surface ...
متن کاملSurface Finishing for Printed Circuit Boards
In a world of ever-increasing electronic component complexity and pin count requirements for component packaging, focus is once again on the age-old question of "How do we preserve solderable surfaces between PWB manufacturing and assembly?" PCB manufacturers today are faced with the decision of which surface finish to offer their customers, while their customers struggle with choosing the best...
متن کاملCorrective Abrasive Finishing Processes for Freeform Surface
Traditionally, abrasive finishing process focus on producing excellent surface finish on regular form shapes. Ever increasing demands in freeform features in aerospace, energy and medicine industry requires abrasive finishing technology not only provides excellent surface finish but also is capable to correct the errors on freeform surfaces. The paper presents current development of corrective ...
