Manufacturing Capabilities


Chip and Wire on Ceramic

Operating from our 180,000 square foot facility in Mansfield, Massachusetts, we have been producing Mil-certified Data Acquisition components since 1970. The hermetically sealed components are assembled in our class 100,000 clean room on thick-film substrates, and all Hi-Rel products are fully tested over their extended operating temperature range.


Chip-Wire and SMT on FR4

To provide the smallest packages at the lowest cost we have introduced a new form of Hybrid, incorporating chip-wire and SMT technology on FR4, housed in Mini SMT Quad-Pak or traditional TDIP.


Surface Mount Technology

Commercial products not requiring hermetically sealed packaging can be manufactured using SMT technology to provide the same performance but at a lower cost.

  • Auto pick and place
  • Manual pick and place
  • AOI inspection
  • Lot control verification
  • Auto pin insertion
  • High-temp solder assembly
  • Through-hole assembly
  • Flying leads
  • Encapsulation
  • ROHS or non-ROHS compliant

Thick Film

Hermetically sealed products manufactured in our Class 100,000 clean room are assembled on thick-film substrates.

  • Conductor, dielectric, glassivation, resistor pastes
  • Single- or multi-layer
  • Thick film resistors screened onto the substrate
  • RoHS and non-RoHS compliant

Test & Environmental

All products, whether using chip-wire, chip-wire and SMT, or solely SMT, are fully tested to their specified static and dynamic parameters. Hi-Rel devices are fully tested under their specified extended temperature ranges. An MES tracking system monitors each step of the manufacturing process and records all test results, providing lot control and traceability for all data acquisition products.
