When package walls, tall components or dense wire loops crowd the bond site, standard tool geometry runs out of clearance. UPT deep-access and fine-pitch wedge tools are engineered for exactly these conditions — tapered profiles that reach into confined spaces, and tip geometries that hold bond quality at 10 µm-class pitch.

Bonding in Confined, Fine-Pitch Packages
Cavity packages, RF modules and dense wire layouts often place bond pads within a few hundred microns of a package sidewall or die edge — conditions where standard tool geometry runs out of clearance before it reaches the pad. UPT deep-access and fine-pitch wedge tools are built for exactly this: tapered profiles that reach into confined spaces without contacting the sidewall, and tip geometries that hold bond quality even as pitch tightens.
The cross-section below is from an actual RF cavity package:
- Bond pad clearance to sidewall: 194.53 µm
- Bond pad clearance to die edge: 238.26 µm
- Cavity depth: ~282.45 µm
Reaching a pad at this depth and clearance without contacting the sidewall is exactly the condition UPT deep-access geometry is designed for.
Sample shown is a decommissioned die used for internal test purposes only and is not associated with any customer program.
