[Analysis Case] Analysis of Organic Foreign Substances on Printed Circuit Boards
Reduce the impact of foreign object surrounding information with appropriate sampling.
Raman spectroscopy is an effective method for the qualitative analysis of microscopic foreign substances. When it becomes difficult to evaluate due to the detection of background information along with the foreign substances, measurements can be performed by combining sampling. Foreign substances on electrodes with minimal background influence were identified as flux, but no information from the foreign substances could be obtained from the foreign substances on printed circuit boards (Figure 1). By performing sampling on inorganic crystals without background influence, information about the foreign substances was obtained, and the foreign substances were identified as flux (Figure 2).
