Solutions Give Emphasis on Highly Reliable, Higher Quality Parts

ontinuing the business pitch it did in 2018, Tokyo Weld Co., Ltd. has marked 2019 as another year to meet the growing need for electronic components with lower profile, to meet demands such as those for smartphone applications, and higher quality and reliability, which are being demanded on the other hand in the automotive industry. In a recent interview with AEI, Koji Takahashi, Managing Director and Chief Technology Officer at Tokyo Weld, improvements and enhancements have been introduced in the company’s growing portfolio of machines to meet the needs of the industry.

“We really intend to improve further the processing capacity of our inspection machines and taping machines in order to respond to the soaring demand from the electronic components industry,” said Takahashi.

Focuses on Core Technologies
As proliferation of devices that embrace internet of things (IoT) technologies becomes more advanced, further scaling down of electronics components has become more pronounced and intensified further in a more rapid pace. The 03015- and 0201-size packages, which are even smaller than the 0402 size, have been introduced for capacitors, including inductors and resistors.

Because of this, Tokyo Weld has moved forward since 2017 with the development of vision inspection machines, measuring/sorting machines, and measuring/taping machines that can handle such microminiaturized packages.

“Similar to what we did in 2018, we intend to step up our efforts in 2019 to improve the performance of models used for handling those microminiaturized packages and expand our product lineup. Also, there is a demand more than ever from users of electronic components in the automotive space for higher quality and higher reliability,” said Takahashi, adding these trends will become more pronounced in 2019.

Above all, visual inspection has also become almost mandatory in addition to the electrical characteristics inspections in this market. The concept of this trend is that “high-reliability and high-quality components should have appropriate visual effect first.”

To cope with this trend, Tokyo Weld has allocated a major portion of its resources to the image inspection business and has expanded this business year after year.

As a new project for this market in 2019, Tokyo Weld is going to start selling a machine integrated with an artificial intelligence (AI) for creating a vision inspection algorithm. This machine is expected to provide a method that is going to simplify the complex configurations, which were previously required for creating inspection algorithms and settings of judgement threshold values previously performed by experts. It is also expected to dramatically reduce and improve the “percentage of conforming parts among components determined as non-conforming parts,” which was the long-term issue of electronic component visual inspection.

To provide support in an industry environment that manufactures electronic components, Tokyo Weld will step up the basic strategy of the company in 2019. It will introduce new technologies and advance the company’s machines to a whole new level, such as electrode application equipment, vision inspection system, measuring/sorting machines, and taping machines.

“We intend to improve the image inspection technology, measurement technology, and packaging technology to guarantee higher quality and highly reliable miniaturized components,” said Takashi.

“To achieve this strategy, we will further develop our core technologies, which are the foundation of our business, and develop a range of products supported by our technological know-hows. This year, we will develop new business and product fields, such as non-destructive inspection machines for electronic components in addition to existing product fields,” he added.
