Please Call: (858) 486-4068 to Order and for Lead Time / Delivery 




High Core melt Temp of 1080C Precision Standoff Height
High Density Capable Easy Substrate cleaning and encapsulation
Excellent Electrical Conductivity 5 to 10 times that of Tin Lead Alloys
Superior Thermal Conductivity Approx 1.3 times that of eutectic alloys


Copper Core EZPlate Solder Spheres are manufactured to the highest industry standards. With a protective Nickel flash plating, the copper core is protected in a gas tight barrier to prevent copper corrosion. Tin over-plating is then added to aid in the wetting of the sphere to standard tin lead solders.
