WHO WE ARE

Fulfilling Engineering Needs of
 World Class Manufacturers

Since our establishment in 2001, TSG U.S.A., Inc. has been a trustworthy partner in design innovation for major electronics manufacturers. We work closely with our clients from the conceptualization stage through the design and verification process. Our mission is to help bring our clients' innovative ideas to life by offering our expertise.

Automotive Grade

Since the establishment of our company, we have primarily served suppliers of automotive electronics. These electronics are subject to numerous challenges, such as environmental variations and vibrations that occur during prolonged warranty periods, which can last up to 10 years. Our team has developed expertise in designing products that not only withstand these harsh conditions but also reliably perform intended functions over time.

Cost-effective Design

Automakers face intense competition based on price, quality, and features. To remain competitive and profitable, they must find ways to minimize costs. Our team specializes in striking the right balance between these competing demands and effectively reducing costs to help our clients maintain their competitiveness.

Accuracy of Analysis

While our electronic equipment is designed to perform as intended when tested individually, it may not function properly when integrated with other devices in a system. That’s why our team specializes in analyzing communication between electronic devices and identifying and correcting any faults that may arise, ensuring seamless integration and optimal performance.

CASE STUDY #1

Electric Power Meter Redesign

Customer Introduction

The client was a leading manufacturer of industrial automation and test-and-measurement solutions.

Problem / Goal

The client’s industrial power meter series was designed in 1990s based on their proprietary ASIC chip. However, their organizational decision led to an end of life of the ASIC. Our mission was to redesign the meter’s electrical circuit without altering its form factors or the user interface.

Solution

Our engineers took advantage of how today’s general purpose MCUs can outperform the ASIC of the 90’s in every respect and redesigned the circuit with an ARM Cortex based MCU, as well as the software that runs on the MCU.

Result & Benefits

Since our engineers were able to redesign the circuit with only widely available electronic components, they were able to secure a lowered BOM cost. Now that all of the functions of the meter are defined by software, instead of the hard wired logic of the ASIC, the product has gained upgradability.

CASE STUDY #2

HVAC System Communication Hub Design

Customer Introduction

The client, a leading HVAC manufacturer from Japan, established a design team in Atlanta to develop products for the North American market.

Problem / Goal

They faced a shortage of engineers and were hesitant to outsource to non-Japanese speaking companies. TSG USA was engaged to design a PCB and enclosure for a communication hub prototype.

Solution

Our experienced design engineers created a functional circuit from provided snippets and designed PCB and enclosure utilizing Altium Designer and CATIA. Drawing on our extensive US engineering service experience, we selected optimal vendors for components, PCB fabrication, sheet metal fabrication, and PCB assembly.

Result & Benefits

Thoroughly inspected prototypes were delivered to the client, enabling them to proceed to the next project stage. The client praised our quick turnaround and attention to detail, expressing satisfaction with the immediate functionality of the prototypes.
