Rapid Analysis of Pb, Fe, Zn, P, etc. of QFe2.5 by Photoelectric Direct Reading Spectrometry
Using photoelectric direct reading spectrometer to analyze fast and accurate characteristics, establish an analysis program, and make a working curve, which meets the requirements of rapid analysis of elements in QFe2.5, and the results are stable and the effect is ideal.
The most important use of copper and copper alloys is to use their excellent electrical conductivity to play a pivotal role in electrical transmission. High-strength and high-conductivity copper alloy is mainly used for lead frame encapsulation materials for large-scale integrated circuits. Its good high-strength and high-conductivity performance is favored by materials science and technology workers all over the world. Since the successful development in the 1980s, copper alloy lead wires are currently available. The frame material accounts for 80-90% or more, of which QFe2.5 is the most representative alloy grade in the Cu-Fe-P system, which is mainly used in integrated circuit lead frame materials, and the market demand is large.
At present, our company QFe2.5 mainly conducts post-furnace analysis by chemical methods, and the analysis speed is slow. The photoelectric direct reading analysis method is known for its fast, flexible and multi-element simultaneous analysis. Using this method to analyze QFe2.5 can save a lot of manpower, material resources and financial resources, and save a lot of money for the company.

Sample selection
The national standard sample iron bronze series standard sample, block sample 1#-~~5# uses a lathe to drive the block sample into a smooth surface, the surface is the upper electrode, the lower electrode is a tungsten electrode with a diameter of 4mm, and the pole distance is 3.0mm. Determined by photoelectric direct reading spectrometer.
1.2.2 Experimental steps
Select the New Calibration menu in the program, create a new analysis program, then activate the standard samples in turn, then set the approximate analysis range and analysis line pair for each analysis element. Enter the sample number of the sample to be excited and the content of each element into the computer. The sample is excited to obtain the excitation intensity of each element, and the working curve of each channel of each element is drawn by software. Calibration curve, regression calculation, selection of the best working curve; setting of standardized samples, type calibration samples; proofreading.
