“…To overcome these disadvantages caused by the mechanical cutting, a laser is intensively used [2][3][4][5][6][7], since laser processing has advantages such as a contact-free process, high energy concentration, fast processing time, and applicability to almost every material. Due to these advantages, laser material processing is actively studied for a variety of cutting and drilling processes [1,[8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Abstract:As electronic products are miniaturized, the components of the spring contact probe are made very fine. Current mechanical processing may make it difficult to perform micro-machining with a high degree of precision. A laser is often used for the high precision micro-machining due to its advantages such as a contact-free process, high energy concentration, fast processing time, and applicability to almost every material. The production of micro-electronics using nickel-coated copper is rapidly increasing and laser material processing is becoming a key processing technology owing to high precision requirements. Before applying laser material processing, it is necessary to understand the ablation characteristics of the materials. Therefore, this study systematically investigates the ablation characteristics of nickel-coated beryllium copper. Key laser parameters are pulse duration (4~200 ns) and the total accumulated energy (1~1000 mJ). The processed workpiece is evaluated by analyzing the heat affected zone (HAZ), material removal zone (MRZ), and roundness. Moreover, the surface characteristics such as a burr, spatter, and roundness shapes are analyzed using scanning electron microscope (SEM).

“…Trautner et al [1] investigated polyethylene (PE) and a rubber material from tire production by employing 157 nm F 2 laser and 532 nm Nd:YAG laser ablation in nitrogen and argon gas background or in air. The effects of laser wavelength on depth resolution of thin-film solar cell are investigated by Choi et al [2] using an ultraviolet (λ = 266 nm) and a visible (λ = 532 nm) nanosecond Nd:YAG lasers. Labutin et al [3] summarize nearly two decades of studies on femtosecond laser-induced breakdown spectrometry (fs-LIBS).…”

Calibration and Validation of Analytical Methods - A Sampling of Current Approaches

Laser-induced breakdown spectroscopy (LIBS) has gained great attention over the past two decades due to its many advantages, such as needless sample preparation, capability of remote measurement and fast multielement simultaneous analysis. However, because of its inherent uncertainty features of plasma, it is still a big challenge for LIBS community worldwide to realize high sensitivity and accurate quantitative analysis. Currently, many chemometric analytical methods have been applied to LIBS calibration analysis, including univariate regression, multivariate regression, principal component regression (PCR), partial least squares regression (PLSR) and so on. In addition, appropriate sample and spectral pretreatment can effectively improve the analytical performance (i.e., limit of detection (LOD), accuracy and repeatability) of LIBS. In this chapter, we briefly summarize the progress of these calibration methods and their applications on LIBS and provide our recommendations.
