T&T Quality Electronics Inc.

Contract Manufacturing & Supply Chain Management

Our History

For over 40 years, our founders have been serving local industry in Southern California, gaining intimate knowledge of the competitive pressures and unique demands U.S. companies face bringing their products to market in a global economy. T&T’s manufacturing model ensures the cost advantage and value proposition of an overseas manufacturing solution while providing the presence, support, on-time delivery, and responsiveness of a local contract manufacturer. With full service capabilities in box build, circuit board assembly, wire and cable assembly, metal fabrication, high precision machining, and supply chain management, we've developed an aggressive cost model integrating a blend strategy that utilizes both local and overseas manufacturing.

This approach allows us to establish a manufacturing solution for customers that minimizes volatility in delivery or quality, while establishing a very competitive cost basis. Customers get the benefits of local contract manufacturing –working side-by-side, local inventory, scheduling flexibility, on-time delivery, tight quality control, quick prototyping turnaround and product revisions, while benefiting from an overseas value pricing model. Our model is very effective, we have all capabilities locally and we have all capabilities overseas. Managing our projects and blending our capabilities where it makes sense for the customer is why we’re successful. No sacrifice in delivery, no sacrifice in quality, nothing lost in translation.


Integral to our success, is our ability to embrace our customers’ objectives and be a valuable contributor in their growth. We recognize that as our customers shift, evolve, and advance, we must also keep pace with their needs. A quality imperative that stays on track with our customer's needs, is an essential foundation to maintaining our agility without sacrifice to the quality standards that our customers have come to expect from us. With this in mind, we keep a close eye on emerging quality imperatives, continually focusing on process improvement, production efficiency, and industry-wide adoption of emerging quality standards & certifications.

T&T is an ISO9001 and AS9100 certified contract manufacturer as well ITAR registered. We also adhere to military standards for a variety of sub-assembly categories as well as maintain strict IPC and RoHS compliance. We closely monitor our manufacturing environment for variables such as temperature and humidity to minimize the impact of environmental factors, and also have a formal FOD prevention program. We also implement comprehensive ESD standards to protect materials and finished goods inventory from electrostatic discharge. Our certifications and standards compliances are as follows:

  • ISO9001
  • AS9100
  • ITAR Registered: M31893
  • J-STD-001
  • IPC-A-610 II, III
  • M227501, M27500, MIL-DTL-38999, IPC/WHMA-A-620 (Cable Assembly)
  • AWS B2.1 (Welding)
  • MIL-C-5541(Plating)
  • MIL-STD-595B (Painting)

Facility and Capabilities

T&T is located in the heart of Southern California in a company owned 27,000 square foot facility, housing capital equipment for metal fabrication, high precision machining, PCB assembly, cable assembly and raw material & finished goods inventory. We can also accommodate installation of subassemblies, hardware, connectors/switches, routing of cabling, wire harnesses, and fiber optics. System build (box build) programs are product centric, utilizing lean manufacturing principles to establish a cost effective assembly process while ensuring your unique manufacturing requirements for your product will not be compromised.

Whether you’re seeking assistance with a specific sub-assembly or desire a solution that encompasses a complete system build solution, we’ll work closely with your staff to ensure smooth integration with your internal manufacturing capabilities. We can support requirements from small mechanical assemblies, to over-sized rack or cabinet assemblies, to break-out boxes or backplanes, to complex circuit board assembly, or to a complete system build with an integrated supply chain and inventory solution. We also specialize in mechatronics based systems that integrate moving mechanical parts with electronic controls, precision interlocks, wiring, brackets and fitments, chassis containing PCBs, and precision machined metal parts containing sophisticated electronics.

Programs can be established around your specific needs and include all or specific aspects of:

Prototyping/NPI Prototyping and NPI support, allowing for seamless integration into an overall manufacturing solution. For customers requiring quick-turn prototype assembly, we can accommodate a 24-hour turnaround upon acquisition of all material.
