  • Productivity Double sided version of S3 with 8 test heads
  • Stability Granit base frame with tension shuttle
  • Flexibility Supports high-end substrate applications


S3-8 is the double-sided model of the single-sided S3 System. The S3-8 has 8 test heads and 2 high-resolution cameras, one on the top side and one on the bottom side. The shuttle of the S3-8 can clamp and tension double-sided substrate boards. For single-sided tests, the S3-8 can be equipped with a vacuum shuttle, which can be mounted in a short time.

Key benefits

  • Catering to the needs of substrate testing

The system combines accuracy and low witness marks with high throughput. It allows double sided ohmic testing e.g. for Kelvin test. But has all the flexibility to deploy also a vacuum table.
