The expanded in-house wire bonding and die attach suite now includes Hesse Bondjet BJ855 and BJ820 automated wire bonders, Westbond 7KE/7KEH and 7476E/747630E manual wedge, ball, and ribbon bond bonders, and a Besi Datacon 2200 Evo Bonder. They've also added a Palomar SST 5100 Vacuum Pressure Furnace for void free eutectic die attach.

With this equipment, Microsembly delivers a full spectrum of wire bonding and die attach services for the manufacturing of RF/microwave PCBAs used in complex mixed technology RF/microwave assemblies.

Wire and Ribbon Bonding and Die Attachment Capabilities

The new systems enable a comprehensive range of precision bonding capabilities:

• Gold (Au) ribbon bonds as small as .002" x .0005"
• Au wedge bonds down to .0007" on FETs, MMICs
• Au ball bonds and stitch-on-ball (SOB) bonds down to .0007"
• Quad diode package bonding with Au ribbon bonds down to .003" x .00025"
• Conductive epoxy die attach bond line thicknesses as little as .002"
• Combination bonds including ball, stitch-on-ball, and ribbon bonding
• Omega wrap (Double-C) ribbon bonds on feedthroughs
• Beam lead tacking with waffle patterning
• Cross bond stitching on ultra-small mesa diodes
• Precise MMIC-to-capacitor interconnects
• Void Free Eutectic Die Attach

"These machines not only add speed and repeatability but also allow our technicians to perform extremely precise and specialized bonds critical to high-reliability systems," said Phuong "Kent" Dang, President at Microsembly. "From ultra-fine interconnects on microwave dies to rugged ribbon bonds on high-power components, we can handle a wide range of RF and microwave assembly challenges with confidence."
