Is it difficult to do switching evaluation of “power semiconductors”? (Part 2)

Hello, everyone.
I’m Zhang from Engineering Department 2.

In my previous blog, I explained the importance of measurement arrangement in the switching evaluation of power semiconductors. This time, I will continue to explain other points to be considered about measurement arrangement.

Pitfalls of waterproof design

Hi everyone, I’m Uemura, Manager of the WTI Sales Department.

Recently, more and more products are becoming waterproof, especially in mobile devices.
Cell phones (smartphones) are typical waterproof products, and it seems that the majority of new products currently on the market are becoming waterproof.

We have seen a rapid increase in the number of requests for mechanical designs with waterproof feature from our customers. For example, products that are constantly placed outside, those that do not specify where to be used, such as sensors, and products supposed to be in portable use, such as mobile products and small measuring devices.

As such, waterproofing is becoming a basic feature in various products on the market, and the importance of waterproofing design is likely to increase further.

Are your packing materials suitable for transportation? Keys to evaluation of packing materials for semiconductor products

Hello, everyone. I’m Sasatani with the package design section of the Tokyo office.

Packing materials for semiconductor products need to be designed to ensure that the products can be properly protected against vibration, shock and compression pressure during transportation, and to be evaluated by performance test. In this article, we will introduce a technique to evaluate whether the packaging materials are properly designed.

What are health care/sports wearable devices? : WTI is also aggressive for these areas

This time, I will talk about wearable devices for healthcare/sports.

With the rise in health consciousness and the development of sensors, materials, and information technology, the development and commercialization of wearable devices has become more active. Wearable devices first became popular in Europe and the United States, and then quickly became popular in Japan as well.

What business fields are most frequently requesting Reverse Engineering Plus to WTI? : Automotive, Power electronics, Consumer use, Wireless, Semiconductors, etc.

Reverse engineering (teardown) is a method of dismantling and disassembling an existing product and analyzing its structure, components, and technical elements.

This method allows us to analyze, research and confirm the technology used in the product, which can be beneficial for development of new products.

WTI receives many requests for reverse engineering (teardown) on a daily basis. For your reference today, I would like to share with you what business fields we have been asked requests for reverse engineering.

Knacks for waterproof design: Cues for escape from the “Trial and Error” approach

As the demand for IoT devices such as wearable devices and outdoor sensors increases, the waterproof design of electronic devices is required more and more.

A waterproof design is much more difficult than one thinks and hard to deal with. It’s not uncommon to have a hard time identifying water leakage points, which is the most important part of a waterproof trouble-shooting. In addition, it’s not uncommon that cost-effective measures can not be found.
