Surface Mount Technology SMT

SMT, called "Surface Mount Technology", is a circuit assembly technology for attaching and soldering surface mount components to a specified position on the surface of a printed circuit board. Drilling without principle. Specifically, it is to first apply solder paste on the printed circuit board, and then accurately place the surface mount components on the solder paste-coated pads, and heat the printed circuit board until the solder paste melts and cools down. After that, the interconnection between the components and the printed circuit board is realized. Acrel owns 8 SMT production lines for mass production of surface mount technology components in the electric meter manufacturing plant. The price has dropped significantly. Various equipment with good technical performance and low price has been launched. Electronic products assembled with SMT have It has the advantages of small size, good performance, complete functions, and low price

Test Center

Test Standard

In Acrel production base has a self EMC test center, also called electromagnetic compatibility (EMC), which refers to the comprehensive evaluation of the electromagnetic field interference (EMI) and anti-interference ability (EMS) of electronic products, which is the product quality One of the most important indicators, the measurement of electromagnetic compatibility is composed of test sites and test instruments.

The purpose of EMC testing is to detect the influence of electromagnetic radiation generated by electrical products on the human body, the power grid in public places, and other electrical products that work normally. In the Acrel EMC test center, the meter will conduct various tests that comply with EMC standards
