Durability through bonding is crucial when it comes to part reliability. One of E-Fab’s promises is to deliver accurate metal parts to exacting specifications and tight tolerances. That promise is significant for flex, electronic, and thin metal circuits in high-technology applications. 


E-Fab utilizes Thermocompression Bonding — a combination of heat and pressure from a  hydraulic press — to compress and bond lamination layers, joining metals to different substrates. Multilayer laminations add mechanical strength, design possibilities, and flexibility.

E-Fab’s Precision Bonding Processes and Advantages

Bonding is a crucial manufacturing process when creating parts for telecommunications, technology, and defense customers. 


Bonding does not impede the flow of electricity.

Electrical Insulation

Circuit boards and electrical equipment have excellent electrical insulation.

Mechanical Strength

Thermocompression bonding delivers stronger parts that are reliable and durable.

Environmental Benefits

The result of the bonding process creates little to no waste and is environmentally friendly.

Power Distribution

Increases the power distribution area, enhancing part performance.

Superior TCE Match

Parts have a better TCE match with silicon after thermocompression bonding
