  If you're experiencing poor bonding performance with your West Bond Laboratory Equipment, several factors could be the culprit. First, the parameters might be improperly set, or the tool may be incorrect. Try fine-tuning or adjusting the power, time, force, or work heat, or consider replacing the tool. Another cause might be contaminated or poor-quality parts, materials, or wire, so clean the components or test with known good parts. Also, check for excessive drag on the wire by inspecting the filter or mechanical drag, ensuring it's set for only slight drag. Finally, too much drag on the wire spool mount can cause issues; try loosening the nut or spring.

  If your West Bond Laboratory Equipment is experiencing issues with improper tail formation, wire loss, or feeding problems, consider these potential causes and solutions. The tail might be improperly set, so try adjusting it. Insufficient wire drag could also be the problem; in this case, replace the filter or adjust it as needed. Furthermore, excessive pull stroke might cause the wire to come out of the tool; adjust the tail accordingly. Keep in mind that this could be due to operator error or technique, and the tail length will vary depending on the looping techniques used.

Why is West Bond Laboratory Equipment tailing after the last bond?
- A
  Ashley HorneAug 23, 2025
  If your West Bond Laboratory Equipment is tailing after the last bond, resulting in a length of wire sticking up, several factors could be responsible. One potential cause is excessive tool heat; try lowering the tool heat. Another factor might be excessive elongation, which can be addressed by using a harder wire. Additionally, insufficient gram force to deform the wire could be the issue, so consider adding more bond force. Finally, wire damage from clamp blades due to improper adjustment or burrs could be the cause; adjust the clamp blades to eliminate any gaps or deburr them.
