ISO 14001 is internationally recognized as the leading environmental management system (EMS) standard for organizations of all sizes. By supporting environmental protection, preventing pollution, reducing waste, and lowering energy and material consumption, the ISO 14001 standard provides a systematic framework for integrating environmental management practices.
ISO45001:2018
The ISO 45001 standard aims to prevent the occurrence of health diseases and work-related injuries and provide a safe and healthy workplace. As a global standard, the ISO 45001 standard is applicable to various fields and different political, economic, business and social environments.
ISO13485:2016
The ISO 13485 standard is implementable by medical device organizations and is the most widely recognized model internationally to help demonstrate an organization's compliance with the laws and regulations of the medical device industry. ISO 13485, as a QMS standard, is regarded as the basis for the EU medical device directives and regulations and the UK UKCA certification.
What are the product categories of LED drivers?
Led's drive is generally referred to as the Led's Luminous Module Controller, which controls the current. If the control current is not good, the lamp may be damaged. Sometimes the current and voltage can be very unstable, then the driver will play a role. So LED drives are very good to check for damage during use. If it is damaged, it can cause the light to dim or turn off directly, and it can also cause flashes.   Led driver is an electronic device that drives the LED light to emit light and work normally. It is equivalent to the heart of the LED lamp. When the driver is in problem, the whole LED lamp will be in problem.   Drivers can be categorized   (1) Constant current:   The output current of the constant current drive circuit is constant, but the output DC voltage varies in a certain range with the magnitude of the load resistance value. Load resistance value is small, output voltage is low, and the larger the load resistance value, the higher the output voltage is.   Constant current circuits are not afraid of short-circuit loading, but full open loading is strictly prohibited.   Constant current drive circuit for LED is ideal, but relatively expensive.   Pay attention to the maximum withstanding current and voltage value used, which limits the number of LEDs used.   (2) Voltage regulator:   When the various parameters of the voltage regulator circuit are determined, the output voltage is fixed, but the output current changes with the increase and decrease of the load.   The voltage regulator circuit is not afraid of load opening, but it is strictly forbidden to completely short-circuit the load.   Drive the LED with a regulator-driven circuit, each string needs to be added with a suitable resistor to make each LED display brightness average;   The brightness will be affected by the voltage change coming from the rectifier.

What is FPGA field programmable gate array
Field programmable gate array (FPGA) is the product of further development on the basis of programmable devices such as pal (programmable array logic) and gal (general array logic). As a semi custom circuit in the field of application specific integrated circuits (ASIC), it not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of programmable devices. The mainstream manufacturers of field programmable gate array FPGA chips include Xilinx, Altera, lattice and MICROSEMI, of which the first two have a total market share of 88%. Field programmable gate array FPGA is a semiconductor device composed of configurable logic block (CLB) matrix connected through programmable interconnection. FPGA can be reprogrammed according to the required application or functional requirements after manufacturing. This feature is the key to the difference between FPGA and ASIC. You can customize FPGA devices for specific design tasks. Although there are also one-time programmable (OTP) FPGAs on the market, most of them are based on SRAM and can be reprogrammed as the design evolves. Field programmable gate array FPGA has a very mature and wide range of applications in the aerospace, military, telecommunications fields. Taking the telecommunication field as an example, in the stage of all-in-one telecommunication equipment, FPGA is applied to network protocol parsing and interface conversion because of its programming flexibility and high performance. In the nfv scenario, FPGA based on the general server and hypervisor can achieve a 5-fold performance improvement of the network element data plane, and can be managed and arranged by the openstack cyborg hardware acceleration framework. In terms of chip design, we need to focus on rationality in algorithm design to ensure the final completion effect of the project, and put forward a solution to the problem according to the actual situation of the project, so as to improve the operation efficiency of FPGA. After the algorithm is determined, the module should be constructed reasonably to facilitate the later code design. In the code design, we can use the pre designed code to improve work efficiency and reliability. Write the test platform, carry out the code simulation test and board debugging, and complete the whole design process. Unlike ASIC, FPGA has a short development cycle. It can change the hardware structure in combination with the design requirements. When the communication protocol is immature, it can help enterprises quickly launch new products and meet the needs of non-standard interface development.

What is the low ESR and high ripple current for solid state capacitors
Capacitors are energy storage elements used in circuits for tuning, filtering, coupling, bypass, energy conversion, and delay. Capacitors are often called capacitors. According to its structure, it can be divided into three types: fixed capacitor, semi-variable capacitor and variable capacitor.   Solid aluminium electrolytic capacitor is short for conductive polymer solid aluminium electrolytic capacitor, and is one of the highest-grade products in capacitor products.   ESR (Equivalent Series Resistance) refers to the series equivalent resistance, which is an important indicator of capacitance. The lower the ESR, the faster the charge and discharge of capacitance. This performance directly affects the decoupling performance of power supply circuit of microprocessor. The advantage of low ESR of solid-state electrolytic capacitance in high frequency circuit is more obvious.   It can be said that the low ESR characteristics at high frequencies are the watershed between the performance differences of solid electrolytic capacitance and liquid capacitance. The ESR of solid-state aluminium electrolytic capacitance is very low, with very small energy dissipation. The very low ESR characteristic of the solid state capacitor under high temperature, high frequency and high power conditions can fully absorb the high amplitude voltage generated between the power cords in the circuit and prevent its interference to the system.   Currently, the power consumption of the CPU is very large, the main frequency is far beyond 1GHz, the peak current of the CPU reaches 80A or more, and the output filter capacitance is close to the critical point of operation. On the other hand, CPUs work in a variety of modes, most of the time in the process of working mode conversion. When the CPU changes from a low power state to a full load state, the large amount of energy required for instantaneous (generally less than 5ms) switching of this CPU comes from the capacitance in the CPU power supply circuit. At this time, the high-speed charging and discharging characteristics of the solid state capacitor can output the high peak current instantaneously, ensuring adequate power supply and ensuring the stable operation of the CPU.
