EB Industries is a leading provider of hermetic electronic packaging services. We have sealed thousands of highly sensitive electronic packages in many different applications. Some of the most delicate and critical work we do – tiny components that must be rendered impervious – happens in our ESD safe and FOD free glove box environments.
The Best Way to Package Sensitive Components in Harsh Environments
Sealing electronic packages using laser welding is the most durable and cost effective way to protect electronic components in the harshest of environments, in the most critical of applications: satellite microwave / rf packages, battlefield command and control systems, deep sea sonar and seismic sensors, and medical implants in the human body. The process involves preparing the assembly and then sealing it into a hermetically secure metal package using a computer controlled laser. The process happens in our dedicated ESD space, using our glove box welding systems.

Application Advantages of Laser Sealed Hermetic Packages
High Reliability
Laser welding provides an exceptionally durable hermetic seal, much more so than epoxy, soldering, or mechanical seals.
Vacuum baked assemblies exhibit less than 1 ppm (parts per million) oxygen and moisture – this is a level of performance that conventional epoxy, solder, and mechanical seals cannot possibly match. The overall glovebox laser welding environment ensures that assemblies remain free of oxidizing contaminants from start to finish.
Flexibility of Container Material
Because Laser Welding can join dissimilar materials and also crack sensitive materials, engineers have a wide range of material options to use in the packaging of the inner components.
Hermetic Packaging Process using Laser Welding
Our base procedure has five stages which ensure maximum protection of the assembly and extremely low failure rates:
ESD/FOD Safe Environment – All parts and assemblies are handled in an electrostatic discharge (ESD) and foreign object damage (FOD) safe room to minimize stray electric charges damaging circuitry. Once parts are readied, they are ready to go into our glove box environment;
Vacuum Baking – Assemblies are baked in a computer controlled vacuum oven, resulting in less than 1 ppm of oxygen and moisture;
Controlled Welding Environment – After baking, assemblies are moved into a glovebox welding station, which is a controlled gas environment which consists of Argon or Nitrogen. Note that the Vacuum Baking and Welding environment are connected and sealed;
CNC Laser Welding – Assemblies are laser hermetically sealed using a CNC controlled laser. The CNC control makes it possible for us to weld complicated cover shapes with relative ease, resulting in a rugged hermetically sealed package;
Leak Checking – Finished hermetic electronics packages are inspected and checked for leaks using Pressure Bombing and Helium Mass Spectrometer testing, then carefully packed for shipment.

Personnel
All our technicians are highly trained and experienced. Additionally, they are supported by full engineering and maintenance staff, a dedicated quality control department and an in-house machine shop.
Equipment
Our hermetic electronic packaging stations, complete glovebox laser welding environments, ensure a computer monitored and controlled process. Assemblies are maintained in a controlled environmental chamber from inert gas drying and vacuum baking to final seal with oxygen and moisture monitoring as well as weld parameter reporting. EB Industries has redundant systems and operators such that our production capability is never compromised.
