Turbo Drying in the Vacuum Drying Oven

The Memmert VO vacuum drying oven is intended primarily to reduce process times, more specifically drying times, in environmental technology, cosmetics, as well as the food and electronics industry. For example the ‘Quality’ working group of the German Association of the Printed Circuit Board Industry (VdL e.V.) together with the German Electrical and Electronic Manufacturers’ Association (ZVEI) in February 2008 compiled a series of guidelines and recommendations concerning the ‘drying of PCBs prior to soldering’ as well as ‘storage conditions for unpopulated PCBs’. This recommendation assumes a considerable reduction in the drying time in the

vacuum, and in addition a lower drying temperature – and therefore reduced energy consumption.

This recommendation is confirmed by analyses made at Memmert customers: drying modules at approx. 60°C and 14 to 16 vacuum drying cycles (alternating between 50 and 900 mbar) in the Memmert vacuum

oven VO reduced the drying time to two hours; a considerable saving in time, but also in operating costs, compared to drying times of sixteen hours in the conventional drying oven. Apart from precision and energy efficiency, Memmert Engineering pays particular attention to quality assurance. Interfaces for logging and printouts, internal memory and convenient ramp programming via software or chip card are of course included in the VO vacuum oven.
