RoHS Testing Equipment – Element Analysis – Thickness Gauge (EDXRF)

The EDX-2 series energy scattered X-ray fluorescent spectrometer is realized by analyzing the element characteristic X-ray wavelength and strength of the element emitted by the sample. The elements contained in the sample are determined according to the different elements characteristics of the X -ray wavelength, and the content of the element in the sample can be determined by comparing the strength of the different elemental spectrum.

1. Product Instruction | What RoHS means?
RoHS is a mandatory standard established by EU legislation. Its full name is “Restriction of Hazardous Substances” (Restriction of Hazardous Substances). This standard has been formally implemented since July 1, 2006 which is mainly used to regulate the materials and process standards of electrical and electronic products. And making it more conducive to human health and environmental protection. The purpose of this standard is to eliminate six items of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers in electrical and electronic products, and stipulate that the content of lead should not exceed 0.1%. The new directive 2011/65/EU (RoHS 2.0) to replace the 2002/95/EC (RoHS) new directive will take effect on July 21, 2011. Comparing RoHS2.0 and RoHS, the main changes are as follows:
• Add Appendix I and IA of the original WEEE Directive as two appendices of RoHS.
• From 1^st,January, 2014 to 1^st, January, 2017, medical equipment and monitoring equipment will be gradually included in the scope of RoHS control.
• Manufacturers need to make an EC declaration of conformity and affix the CE mark before the product goes on sale. After the sub-electrical products on sale in market, relevant technical documents and EC declarations of conformity must be retained for at least ten years.
• If the substances listed in Appendix III (such as HBCDD, DEHP, BBP, DBP, etc.) cause the human health and the environmental unacceptable harzards, it will be evaluated in accordance with the provisions of Articles 69 to 72 of the REACH Regulation, and this substance will be further included in the restricted substances in Appendix IV.

The main test substances in RoHS requirements are as follows:

2. RoHS Test Method | How to do the RoHS Test?
“Testing Methods for Toxic and Harmful Substances in Electronic Information Products” (hereinafter referred to as “Testing Methods”, the standard number is SJ/T 11365-2006) limits the testing methods for harmful elements in the RoHS requirements. Among them, X-ray fluorescence spectroscopy (XRF) has been established as a quick screening method as the fastest and most convenient method. X-ray fluorescence spectroscopy (XRF)/RoHS Analyzer can be used to accurately test the corresponding standard samples of the five elements of lead (Pb), mercury (Hg), cadmium (Cd), chromium (Cr), and bromine (Br).
