Frequently asked questions
What types of wire can the machine bond?General reference — not yet source-verified
Wire bonders of this class typically handle gold, copper, and sometimes aluminum wire. The specific wire material compatibility depends on the bond head design, capillary geometry, and the ultrasonic frequency used.
What is the typical throughput of such systems?General reference — not yet source-verified
Throughput varies by machine class and application, but these systems are designed for high-speed operation in volume manufacturing. Actual bond rates depend on factors such as bond length, size, and complexity of the bond program.
What kind of bond quality inspection is available?General reference — not yet source-verified
Many wire bonders incorporate vision systems for bond placement verification and offer integrated pull or shear testing capabilities for process control and quality assurance.
What substrate types are supported?General reference — not yet source-verified
Wire bonders can accommodate various substrate formats, including lead frames, BGA substrates, ceramic packages, and other package types, with appropriate tooling and handling options.
Is the machine capable of multi-level bonding?General reference — not yet source-verified
Yes, when configured with suitable software and bond head motion capabilities, these machines can bond to multiple levels, such as different die heights within a stacked-die package.
