JetEtch Pro

The JetEtch Pro is easy to operate cost effective solution to IC package decapsulation.

Intuitive software directs the operator step-by-step through the simple programming sequence. Once set, the software enables an entire etching program to be completed with only two keystrokes.

In addition, the JetEtch Pro delivers unsurpassed results by providing unique and precise software control of all aspects of the decapsulation process.

Innovative Features of JetEtch Pro:

  • Industry-leading safety features
  • Faster etch processing times
  • Flexible etch head designs
  • Superior pump longevity
  • The most effective software in the industry

Comprehensive capabilities for Single and mixed-acid etchants.

  • JetEtch unique software and hardware enable a user to program a wide variety of etch parameters using any combination of ratios from 1:0 to 1:6, in both nitric-to-sulfuric and sulfuric-to-nitric concentrations. Temperature is regulated to prevent any mixed-acid etchant from exceeding 100ºC, to ensure that the nitric acid will not steam or boil.
  • Front digital indicator to display real-time material removal (sample advancement), 1 µm resolution.

Faster Etch Processing Times

  • Large inner-diameter tubing increases acid flow, for faster etches.
  • New pump design offers a greater range of flow rates.

Flexible Etch Head Designs

  • Fixed Etch Head — Made of silicon carbide, our unique Etch Head assembly ensures faster etch times, greater resistance to acids, and less maintenance.
  • Removable Etch Head Configuration — We offer an optional, removable Etch Head configuration that enables the use of several different inserts, ensuring that even the most challenging packages can be opened.

Leading the Industry in Safety

  • Unique Waste Diversion System. Waste acid is disposed into separate bottles via a unique diversion system that minimizes user interaction with acids.
  • Robust Cover Arm Assembly — The automatic, pneumatically controlled cover assembly ensures that the process chamber remains hermetically sealed for the entire etch cycle. This is far superior to less sophisticated, manually operated lid covers, which can be opened at any time during the etch process, exposing the user to dangerous hot etchant.

The Most Effective Software on the Market

  • The JetEtch Pro can permanently store up to 100 etch programs for fast recall.
  • The software is also able to mix up to 13 different acid ratios, with no direct operator contact.
  • Combined with a choice of nitric or sulfuric acid post-decapsulation rinse, etch intervals in one-second increments from 1 second to 1800 seconds, and a temperature range from 20º C to 250º C — the number of decapsulation programs available is in the millions.

Superior Pump Longevity

  • Patented micrometering pump is the gold standard in acid delivery and longevity. It is backed by an extended pump warranty a five-year, no-questions-asked guarantee.

Etch Modes

Vortex Etch
Vortex Etch produces an etch cavity with extremely straight sidewalls when used with lower-temperature nitric or mixed-acid ratios. The straight sidewalls result from the bidirectional acid flow combined with the abrasive action of non-soluble encapsulant filler that is released from the plastic polymer as the encapsulation is dissolved. Vortex Etch is the preferred method for the precise opening of small cavities when using either nitric or concentrated sulfuric acid.

Pulse Etch
Pulse Etch generally uses greater acid flow rates than Vortex Etch. The result is an etch cavity with a more curved sidewall. Typically, Pulse Etch is ideal for opening large cavities. This is often the preferred method for exposing second bonds when etching ICs that do not have chip-scale configuration.

++JetEtch Pro Minimal Etchant Use
The JetEtch Pro is designed to minimize acid use. Acid volume is software selectable from 1–10 mL/minute. Our efficient design means that whether using Vortex or Pulse Etch mode, opening any package never requires etchant flow rates greater than 1–10 mL/minute.
