Optimized Manufacturing

Component Manufacturing
II-VI Marlow originated as a thermoelectric component supplier to U.S. military and space agencies more than 35 years ago. Built into the company’s foundation is a commitment to quality and dedication to putting the customer first.

As a result, II-VI Marlow approaches the component manufacturing process with your business and technology requirements as a central priority. Although II-VI Marlow offers standard, off-the-shelf products for purchase online, customers often select an optimized-to-spec thermoelectric component to ensure the best match for their application’s requirements.

During the optimization process, engineers factor in performance, dimensions, packaging, reliability and cost to meet the specifications identified by the customer. In a production environment, the extended lifetime, reliability and performance enhancement gained through an optimized design translates to significant savings over the program’s lifetime.

Highlights

  • Component variations:
    Dimensions ranging: 2mm2—80mm2
    Solder temperatures: 138°C—305°C
    Ceramic selections: AlO, AlN, BeO
  • Accessories: lead wires, pre-tinning, exterior metallization, sealing, package mounting
  • Production from U.S. or Vietnam facilities
  • Volume production capacity to 1M+ units/month
  • Advanced quality systems

As the foundational element of our business, the development and manufacture of thermoelectric components remains a key focus, even as the business expands to provide more sub-assembly and end-product offerings.

Our Optimize-to-Spec solutions offer complete flexibility to optimize thermoelectric components and assemblies to meet your application requirements.

Working from standardized components and processes, each thermoelectric solution may be optimized for:

  • Performance
  • Dimensional constraints
  • Power consumption
  • Product lifetime
  • Durability
  • Testing/compliance

The optimization process begins with an application consultation and results in a perfectly tailored solution to fit your requirements – offering the maximum performance while delivering cost savings through production efficiency, extended product lifetime and reduced PPM.

Sub-Assembly Manufacturing
II-VI Marlow also offers extended contract manufacturing services to develop thermal sub-assemblies to meet customer requirements. Thermoelectric components are combined with heat sinks, fans, power supplies, temperature control electronics and more to ensure proper integration with your end-product design.

Maintaining an internal thermal design team or locating a contract manufacturer with thermoelectric expertise is cost-prohibitive. For II-VI Marlow, low-cost manufacturing in Vietnam offsets the cost. II-VI Marlow keeps the thermal components together and optimizes the entire system to offer the maximum benefit.

For sub-assembly builds, II-VI Marlow assigns a dedicated, local program manager to act as a liaison between you and all facets of the manufacturing process. Program managers ensure that your requirements are fulfilled at every stage while delivering consistent feedback on production status, quality audit results and inspection reports.
