DOHONE's Solid Magazine is the "foundation" of the wire bonder

2026-08-21

Semiconductor packaging and testing wire bonders rely on ultrasonic energy to bond gold wires and aluminum wires to chip pads and lead frames. This process requires positioning accuracy at the micron level: mainstream equipment achieves a positioning accuracy of ±1.5μm, while next-generation models are continuously iterating toward the sub-micron level.

The lead frame is transported from the magazine (Solid Magazine) to the wire bonding station, and the magazine serves as the core positioning reference for the entire transport process. If the slot accuracy of the magazine is insufficient, the lead frame will experience slight deviations within the feed track. Such deviations may be only 0.05mm—barely perceptible to the naked eye—yet they directly cause the wire bonder's vision recognition system to experience alignment drift, leading to solder joint offset, cold soldering, and in severe cases, even cracked dies.

To ensure stable operation of the wire bonder and strictly control product yield, high-precision Solid Magazines are essential. With over two decades of deep experience in the manufacturing of semiconductor carriers and loaders, DOHONE offers a one-stop Solid Magazine solution package, helping enterprises enhance product quality and production efficiency.
