Introduction Product development and quality assurance in many sectors cannot proceed without extensive environmental testing. Manufacturers may test the performance, durability, and resistance to deterioration of their materials and products by simulating the extreme circumstances that they may meet in the real world. The use of salt spray chambers is a common technique for environmental testing....
Isolation transformer is a special type of transformer, which has its input and output winding connected in an electrically isolated fashion, mainly used in occasions with reverse phase separation, to realize electrical isolation and simultaneous voltage step-up/down. The main application of isolation transformer is to electrically isolate two related circuits, usually applied in electronic indust...
The terms electromagnetic compatibility (EMC) and electromagnetic interference are often used interchangeably when talking about the testing of commercial electronic goods and products. Because the two types of tests share so many similarities, it’s very easy to confuse one with the other. In this article, we will attempt to highlight some of the major differences between EMC and EMI testing. We...
In the production process of electronic devices, there is always a crucial step, and using a high and low temperature chamber to test product quality has become that crucial step. So, why do electronic products need to be tested? With the development of technology, electronic products gradually develop integration and structural refinement, with more processes and increasingly complex manufacturi...
I. Overview of the Development of Integrating Sphere Spectrophotometer Analysis System In spite of the advantages of simplicity, reliability and stability of the measuring system of integrating sphere with photometric probe, the inconvenience of measuring color and the impossibility of measuring non-continuous spectra make it less used nowadays. The primary method for measuring the light color of ...
