Our philosophy is simple:  Quality cannot be inspected into a product.  It must originate with the initial design, and continue throughout all other manufacturing and supporting functions.  Our Quality requirements are fulfilled when the customer receives a highly-reliable product in full conformance with all applicable specifications and inside the requested delivery date.

Quality Assurance is the basis for our confidence in the reliability of your hybrid circuit.  Our team utilizes Dektak3 equipment to measure material thickness as small as 5,000 Angstroms.  Our staff undergoes an intensive training program that focuses on:

  • Post-delivery evaluation

  • Vendor evaluation

  • Material analysis and qualification

  • Equipment calibration

  • Process auditing

  • Product performance monitoring

Quality Control is rigorous and consistent. Our inspectors are trained to act as your representative during the manufacturing process and perform:

  • Incoming inspection

  • In-process inspection

  • Final Electrical and Mechanical

  • Certificates of Compliance

HSI is committed to a socially-responsible supply chain and committed to supporting RoHS, REACH, and Conflict Materials protection.
