Collaborative Success Stories

“We have worked together with KJLC on the design of an UHV chamber and other components to build the first prototype to produce our novel passivation process for compound semiconductors. We have used their online design tool and their 3D component libraries and product configurators to get the preliminary 3D of our system, the whole process was extremely easy and fast. Their engineering team is very skillful and friendly and it has given us excellent support during the whole project and specifically in the design of complicated components such as customized transfer systems. We have received the system on time and with premium quality from the first bolt all the way to the packing materials! We are very happy with the end result as well as with the whole relationship and how KJLC has dealt with the project. They have proven to be a top supplier and now we are willing to continue doing business together. Thank you for the great work.”
