Are your MSD safely stored? As humidity is found to be one of the key reasons for rejected products, many manufacturers are taking measures to control the humidity to increase their production efficiency and save the cost. In the industries of semi-conductor and electronics, the key section in which the rejected products are most probably to be made is that during the heating process of SMT, the IC(e.g.,PBGA,BGA,or TQFD) is likely to crack and thus cause non-effective welding because of the humidity. Climatest Symor® auto dry cabinet is the best solution to avoid the cracking and non#2;effective welding by dehumidifying the surface of your components. The dry unit can be used for 20 years without replacement,and controller is calibration free within 5 years.We attach dry cabinet application with different humidity range,welcome to download.
Viconics� mission is to provide value and innovation in microcomputer-based temperature and humidity controls for the commercial HVAC market. Products range are controls, from thermostats and humidistats to sophisticated heat pump controls.

Creep corrosion on printed circuit boards (PCBs) is the corrosion of copper metallization and the spreading of the copper corrosion products across the PCB surfaces to the extent that they may electrically short circuit neighboring features on the PCB. The iNEMI technical subcommittee on creep corrosion has developed a flowers-of-sulfur (FOS) based test that is sufficiently well developed for consideration as an industry standard qualification test for creep corrosion. This paper will address the important question of how relative humidity affects creep corrosion. A creep corrosion tendency that is inversely proportional to relative humidity may allow data center administrators to eliminate creep corrosion simply by controlling the relative humidity in the data center,thus, avoiding the high cost of gas-phase filtration of gaseous contamination. The creep corrosion relative humidity dependence will be studied using a modified version of the iNEMI FOS test chamber. The design modification allows the achievement of relative humidity as low as 15% in the presence of the chlorine-releasing bleach aqueous solution. The paper will report on the dependence of creep corrosion on humidity in the 15 to 80% relative humidity range by testing ENIG (gold on electroless nickel), ImAg (immersion silver) and OSP (organic surface preservative) finished PCBs, soldered with organic acid flux.
