Notice of discontinuation of the SW series (while supplies last)

We use high-performance and reliable products from Japanese manufacturers for not only electrolytic capacitors but also most other major electronic components.

The characteristic of Japanese electronic components is their high reliability, which is achieved through the meticulous design and manufacturing processes unique to Japanese manufacturers. As a result of adopting these components and designing them domestically, the AC adapters themselves can maintain stable quality for a long time compared to overseas-made adapters. (We have successfully kept product costs down by conducting assembly overseas.) Our website → Products → AC Adapters → High-Quality Switching AC Adapters * As of April 1, 2020, we received notice from the manufacturer that production has ended, and sales will conclude once our stock is depleted. * On May 16, 2022, the "SW-1212S" stock was exhausted. * On July 1, 2024, the "SW-0522E" stock was exhausted.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

What is a leak test system specifically for small electronic components? It is a device used for leak testing small electronic components that require airtightness, such as crystal devices, ceramic oscillators, optical devices, power semiconductors, CAN devices, laser diodes, MEMS devices, SAW filters, small relays, and capacitors. Leak testing of sealed products requires two types of inspections: gross leak testing and fine leak testing. We offer fully automatic machines that can perform the entire process in one unit, as well as dedicated machines (custom-made) and convenient tabletop types for sampling inspections.

● What is a packaging container air leak test device? It is a leak testing device that identifies the peeling, tearing, and presence of pinholes in packaging containers for pharmaceuticals and other products, conducting a Container Closure Integrity Test (CCIT). It can be applied to a wide variety of packaging containers, including flexible packaging, bottle containers, and glass containers, primarily in pharmaceutical packaging. The measurement method employs the <sealed chamber method (pressure change leak testing method 1)>. A sample is placed in the chamber, and by applying pressure or vacuum and measuring the pressure change within the chamber, quantitative inspection is performed. It can be used in various scenarios, including offline manufacturing, inline manufacturing, CMC laboratories, quality control laboratories, and stability testing. * The containers subject to inspection are referred to as "work" or "samples." Here, specific samples are referred to as "samples" to differentiate the terminology.

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.

What is a sealed product air leak test device? It is an air leak test device that inspects the airtightness, sealing performance, and waterproofness of electrical equipment and packaging containers (cosmetics, food). It tests for leaks in products such as smartphones, tablet devices, keyless switches, wristwatches, bottle containers, and cosmetic containers (eyeliner, mascara).
