ENTROPY LTD LLC

Chemical Cleaning and debrazing to UHV requirements:  Ceramics, Plastics, Metals and other materials Removal of Particles, glass cleaning, removal of polymer films on fused silica, Hydrocarbons, Inorganic Salts. 

Ultra High Vacuum Specialist and UHV System Design:  vacuum processing system design, leak detection systems and gas handling. Micro contamination control. Vacuum courses, proper handling of UHV components, leak detection classes and contamination awareness education. Using Mass Spectrometers and alternative processing such as flow through for improving your vacuum process.Experience with doing lifetime studies and leak up rates and gas analysis. Outgassing studies to improving sealing surfaces to better vacuum brazing to improving system performance by provisioning with the correct material and or type of vacuum seal.

PIC MICRO CONTROLLER; Basic system control (open, close valves pump down times) controlled with either basic electronics or use of PIC micro controllers with customizable software of our design. Cost savings step reduces expenses for other system control schemes.

POLYMER SEALS: Hermetic Seal Development: Develop polymeric seals for vacuum applications. Reformulation of polymers with ceramics and nano particles provides superior mechanical properties and reduced permeation rates than standard polymers. 

Viscous flow processing:  A low temperature ~ 100 C Vacuum Process for packaged devices that require removal of internal volatile contaminants but cannot be subjected to the high temperatures  required by standard vacuum processing methods.  Depending on processing time, ppm levels can be attained with proper device preparation and bake out conditions, interface design - device bakeout does not need to exceed 100 C in many instances)  vs standard vacuum processing.Especially useful for moisture removal. The advantages are lower device bakeout temperature and is not constrained by vacuum interface conductance) Please see our new technical section for details.

Chemical and materials investigations: The appropriate surface or bulk analysis of a material can provide valuable insight into how it reacts with its operational environment.  Understanding that the surface determines the material properties in many cases. For optical materials the surface can alter the performance, longevity and reliability of a device.  Many times a better understanding of material properties will provide a framework for device failures and lifetime.

Process control and development:  Entropy LTD has proven success in solving difficult manufacturing issues in a variety of industries, semi conductor, optical, laser, x ray tube, hi intensity lamp manufacturers and bio technical.  With experience working in many fields this is brought to bear on issues from thermal optics, to fixing semi conductor chips from failing QC testing. There have been many significant challenges that have been resolved helping companies reduce warranty costs, improve yields and increase product lifetime.  Contact us for your specific requirements.

We also offer yield and performance improvement services for manufacturers.

With over 32 years of technical experience in Chemistry, Engineering, Materials Science and Ultra High Vacuum Technology- Entropy LTD LLC is uniquely qualified to help your company with cost effective and highly reliable methods to tackle Micro Contamination issues.
