Precision Lead Bonding for 2026 R&D: Why the WS3100 Desktop Wedge Bonder is the New Lab Standard
Engineered for Power Electronics Prototyping
While high-speed automated bonders dominate mass production, R&D labs require granular control over the bonding physics. The WS3100 excels in the internal lead bonding of medium-to-high power transistors, IGBTs, and thyristors.
Key Technical Advantages for Laboratory Use:
-
Broad Wire Compatibility: Handles aluminum wire diameters from 75µm to 500µm (3–20 mil), allowing engineers to prototype everything from small-signal diodes to high-current power modules on a single platform.
-
Dual-Bond Programming: Features dedicated channels for separate 1st and 2nd bond pressure, time, and ultrasonic power. This is critical when bonding between dissimilar surfaces, such as a silicon carbide die and a direct bonded copper (DBC) substrate.
-
Multi-Point Bonding Modes: Supports Mode 2 Dual-Bonding (Dual 1st/Dual 2nd), a necessity for reducing bond resistance in high-current power devices and improving overall device reliability.

Advanced Features for Academic and Industrial Labs
The WS3100 is not just a manual tool; it is an intelligent desktop bridge.
-
Automatic Frequency Tracking: The generator automatically captures the transducer's resonant frequency within ≤5ms at start-up, ensuring that every bond receives the exact energy profile set by the researcher.
-
Stepper Motor Precision: The Z and Y movements are computer-controlled via precision linear guides, eliminating the mechanical "slop" found in legacy desktop bonders.
-
Environmental Versatility: With a net weight of approximately 40kg and a compact footprint (740*690*550mm), the WS3100 fits seamlessly into standard cleanroom workbenches.
FAQ for Semiconductor Researchers
Q: Can the WS3100 handle SiC and GaN prototyping?
A: Yes. Its wide pressure range (up to 1200g) and powerful 30W high-range ultrasonic output are specifically designed to overcome the harder metallization challenges associated with wide-bandgap (WBG) semiconductors.
Q: What type of wedges are compatible with the WS3100?
A: The system uses standard ø3*25.4mm wedges with a 45° wire entry angle, supporting common models from LW75 to LW500.
Q: How does the machine handle inconsistent die heights in R&D samples?
A: The WS3100 features a "Zeroing/Reference Height" detection system, allowing the bond head to automatically adjust the aim point and loop heights for non-planar samples.
