It is necessary to know there are some faults that cannot be entirely avoided during the use of temperature and humidity test chamber, but how to deal with them in time is a problem that needs to be paid attention to.Here mainly explain the temperature and humidity test chamber compressor in the reason for the water, and how to deal with it. Reason: water comes from air, because there is always water in the air, known as humidity, which is compressed into supersaturated air and then analyzed to become liquid. The oil comes from the lubrication system of the compressor, possibly because the wear clearance of the mechanism increases, and the lubricating oil will escape into the cylinder. Solution: after the compressor is removed from the temperature and humidity test chamber, with a larger gas storage tank, the oil and water will naturally settle down to the bottom of the jar, and we need to discharge regularly to reduce the oil and water content in the compressed air. Of course, you can also use filters and other things to further reduce the content of oil and water. if you need to know more details about climatic chamber, keep an eye on our website www.climatechambers.com

Silicone contamination is known to have a negative impact on assembly processes such as soldering, adhesive bonding, coating, and wire bonding. In particular, silicone is known to cause de-wetting of materials from surfaces and can result in adhesive failures. There are many sources for silicone contamination with common sources being mold releases or lubricants on manufacturing tools, offgassing during cure of silicone paste adhesives, and residue from pressure sensitive tape. This effort addresses silicone contamination by quantifying adhesive effects under known silicone contaminations. The first step in this effort identified an FT-IR spectroscopic detection limit for surface silicone utilizing the area under the 1263 cm-1 (Si-CH3) absorbance peak as a function of concentration (µg/cm2). The next step was to pre-contaminate surfaces with known concentrations of silicone oil and assess the effects on surface wetting and adhesion. This information will be used to establish guidelines for silicone contamination in different manufacturing areas within Harris Corporation...
