High drying temperatures could also distort fine-pitch apertures and screen tension due to irregular expansion and contraction. 2001 Stencil Dryer Smart Sonic has introduced the industry's first independent stencil dryer. The most common bottleneck of a stencil cleaning operation is the drying cycle. While washing and rinsing may only take 5 to 10 minutes, the drying cycle often requires an additional 10 to 15 minutes. The overall height is only 36-inches allowing for easy loading and unloading of large stencils.
Controls are adjustable to suit other applications such as drying pallets, oven radiators and PCBs.
The Smart Sonic Stencil Cleaning Process may have yet another accolade to add to its list of prestigious distinctions. President Clinton announced the Presidential Green Chemistry Challenge in 1995. The program was established to recognize and promote fundamental and innovative chemical methods that accomplish pollution prevention through source reduction and that have broad applicability in industry. Stencil cleaning has been identified as the most hazardous process with the greatest potential environmental impact associated with printed circuit board assembly. In addition, 440-R SMT Detergent is formulated to clean all types of solder paste at ambient temperature, which serves to conserve energy and maintain stencil integrity over chemistries requiring elevated cleaning temperatures.
