With the development of scientific technology, the electronic devices prevail in our daily life. The characteristics, function and service life of them are influenced by varying thermal and climatic conditions during transport, storage and use. It is significant to test the functional reliabilities of these electronic components, so as to safeguard and optimize the quality of the products. The environmental and climate test chambers produced by Envsin provide an integrated solution to avoid quality problems. By using these equipments, the reliabilities of electronic products can be substantially improved.
