RoHS Tester RoHS Elemental Analysis

1. RoHS background:
For the first time, it is noted that electrical and electronic equipment contains heavy metals that are harmful to human health. It was found in the cables sold in a batch of game consoles sold in the Netherlands in 2000. In fact, the ink printed by electrical electronics in production contains harmful heavy metals such as lead.

2. The official start time of RoHS:
In order to protect the environment of the earth and reduce the impact on the deterioration of the ecosystem, protect human health, and maintain the sustainable and healthy development of human society, the EU issued the “Instructions on Scrap Electronics Electric Equipment” on 13th February, 2003 (2002/96// EC, referred to as Weee for short) and “Instructions on the use of certain harmful substances in electronic and electrical equipment” (2002/95/EC, referred to as RoHS), RoHS Lead (PB), mercury (HG), hexavalent chromium (CR6+): 1000 ppm (0.1%),
Cadmium (CD): 100PPM (0.01%), and the electronic electronic electronic and electronics products that exceeded the multi -bromodyl (PBDE), polymodiabenzene (PBB): 1000 ppm (0.1%) and other flame retardants Essence

China promulgated the RoHS management measures on 28th February, 2006, and the implementation of RoHS officially began on March 1, 2007. The above RoHS detection project industry is collectively referred to as RoHS 1.0.

Considering that it takes a certain period of time to meet the requirements of new harmful substances, (EU) 2015/863 stipulates the corresponding transition period: all electronic and electrical products (except medical equipment and monitoring instruments) need to be satisfied from 22nd, July, 2019 to be satisfied New requirements, medical equipment and monitoring instruments must meet new requirements from 22nd, July, 2021. The above RoHS detection project industry is collectively referred to as RoHS2.0.

3. RoHS working principle:
The important part of the X fluorescence spectrometer used during the RoHS detection is mainly composed of detectors, multi -pulse analysis instruments, sample laboratories, X fluorescent rays, amplifiers, and data systems that process data. The working principle of this X -fluorescent spectrometer is mainly because high -energy X-ray is stimulated by the internal jump inside the atom. This X -ray has a specific wavelength, so according to this specific X -ray radiation in the radiation of the atom in this specific X -ray The relationship between the size of the radiation energy strength and its own content is laying a foundation for the quantitative analysis of the X fluorescence spectrometer in the RoHS detection.

4. Use the technical requirements of the RoHS tester:
When using the X fluorescent spectrum for RoHS detection, it is necessary to ensure that the appearance of the instrument is clean and the external structure is complete. Various signs on the instrument, such as the model of the instrument, the instructions of the instrument panel, the factory number of the instrument, and the readings of the instrument. The clear logo; the safety protection accessories and indicator lights on the panel can perform normal work; the work performance of its electrical work is maintained when the instrument is powered on; It is allowed to display the value of the calibration instrument according to and meet the various indicators and technical requirements in the instruction manual.

5. What device to use RoHS1.0 and RoHS2.0?
At this point, there are 10 kinds of projects tested in RoHS
Testing RoHS 1.0 elements, we usually use energy color scattered X fluorescent spectrometer to test lead (PB), mercury (HG), cadmium (CD) content, as for hexavalent chromium CR (6+), polyzide diodes (PBDE) (PBDE) (PBDE) , Polymodiabenzene (PBB), few customers are tested directly. First, test trouble, second, the cost of equipment is high. Therefore, using EDX-2 fluorescent spectrometer to detect the total chromium CR (including hexavalent chromium CR6+) and total bromide (including PBDE (PBDE), polymodiabenzene (PBB)), the test speed is fast. result. The  EDX-2 RoHS tester manufactured by LISUN fully meets the test requirements of RoHS 1.0.

Advantages and features of EDX-2 RoHS tester:
• High-resolution, high-definition camera for easy operation.
• All imported core technology and original parts from Europe and America.
• Camera and cabin lighting system, real-time view the test position of the sample.
• Reliable power supply over-current and short-circuit protection to ensure equipment safety.
• Automatic control test system, convenient for customers to use.
• Already include the gold plate and standard material EU calibrate certificate.

LISUN EDX-4 RoHS 2.0 test equipment meets the requirements of IEC62321-8. The four kinds of o-benzene controlled by Rohs2.0 are plasticizers and are hardly volatile materials. They need high temperature (200℃-450℃) to evaporate.

EDX-4 ROHS 2.0 Test Equipment

The current IEC standard is PY/TD-GC-MS (thermal cracking/ Thermal desorption-gas chromatography-mass spectrometry detector), where the thermal cracking temperature is high, up to 1200 degrees, many large molecular substances are cracked into small molecular substances, which will Interference and false positives to the results, so need to use MS mass spectrometers to qualify. And this equipment we use EDX-4 micro-cracking desorption technology (thermal cracking/thermal desorption-gas chromatography), we only need to quantify the corresponding o-benzenes, so our heating range is set in the range of 200°C-450°C, so that all four o-benzenes are volatilized and enter GC (gas chromatograph) for quantification without affecting the results of other macromolecular substances.

LISUN RoHS 2.0 mainly tests the following elements:

Analysis condition:
• Micro-pyrolysis program temperature rise 200 ° C -450 ° C
• Microthermal cracking time 2 min
• Injection method: split injection
• Liquid injection volume: 1 ul
• Solid injection volume: 5mg or less
• Inlet temperature: 250 °C
• FID detector temperature: 300 °C
• Temperature programmed to 50 °C (for 1 min), to 20 °C per minute to 450 °C (for 4 min)
• The method does not require pre-treatment, the consumable is 2.5cm long quartz tube, quartz cotton, pretreatment column, the solid sample is placed in the middle part of the quartz tube, the two ends are fixed with quartz cotton, and then the prepared sample tube is placed in the heating chamber Just fine.
