> In-Line Monitoring

With over 60 production steps in our manufacturing process, it is imperative to have full visibility of our production line, to execute immediate corrective action when issues arise. We have standard operation procedures (SOP) in all processes of the business. This creates a paper-trail at every step in the process, so that all problems can be traced back to the source. Our technical equipment is monitored in real time, using computerized fault detection and diagnostics to signal any malfunction; this gives us great visibility and helps us pin-point the components that are responsible. The system also enables immediate correction and allows qualitative and quantitative evaluation of system reliability.

Wafer Works regularly reviews and evaluates all operational processes for improvement purposes, and asks all employees to actively search for improvement to exceed customer's expectations.
