Electronic packaging - Micro Friction Stir Welding

To find out more about TWI’s technologies please visit or to read more about TWI’s training courses visit TWI has developed a technique that enables ultra-thin aluminium alloy sheet to be joined by a process that uses neither glue nor welding filler wire. This new technique, called micro-friction stir welding (µFSW), has achieved perfect and permanent lap-welded and spot-welded joints in less than material thickness and butt welds i
