Featured Content ■ Latest Trends in BGA Implementation Board Inspection Hybrid Inspection of Flying Probe Testers and JTAG Testing Andor System Support Co., Ltd. / Masazumi Taniguchi Takaya Co., Ltd. / Kohei Yanagida Overview BGA (Ball Grid Array) components have become widely used in various electronic devices, ranging from consumer products to industrial equipment, and more recently, automotive devices. However, a reliable method for inspecting boards with BGA components (hereafter referred to as BGA implementation boards) has not been established. This is because every inspection method has its advantages and disadvantages, and it is impossible to conduct a complete test using only one inspection method. Therefore, inspecting BGA implementation boards has become a challenge for many companies. In this article, we will introduce the latest technological trends in hybrid inspection that combines flying probe testers and JTAG (Joint Test Action Group) boundary scan as one solution to this issue. 1. Introduction 2. Inspection and Challenges of BGA Implementation Boards 3. Possibilities of Electrical Testing 4. In-Circuit Testing 5. JTAG Boundary Scan Testing 6. Hybrid Testing 7. Conclusion

• Measurement and Inspection

We will create new value through the mutual complementarity of ICT and BST.

In-circuit testing with flying probe testers excels at inspecting the electrical characteristics of implemented electronic components in analog circuits. However, components that cannot be probed make electrical testing difficult, and functional testing of digital circuits is challenging. On the other hand, boundary scan testing allows for quick interconnection testing between LSI pins and on-board programming for FPGAs, but it can only test digital circuits around ICs that comply with the boundary scan standard, and it also requires dedicated fixtures for connections. At Takaya Corporation, we possess technology that uses flying probes instead of fixtures that connect 4 to 5 scan-compatible pins and measuring instruments required for boundary scan testing. This allows for boundary scan testing even when the counterpart of a boundary scan-compliant IC is a non-boundary scan-compliant IC or passive components (such as connectors), by enabling the flying probe to function as a virtual boundary scan cell. With a single flying probe tester, it is possible to conduct comprehensive testing of both digital and analog circuits, thereby significantly enhancing testing efficiency compared to before.

This is a flagship model that arranges probe heads above and below, enabling simultaneous in-circuit testing of both sides of the substrate.

Four probes are arranged on the top side of the substrate and two on the bottom side. Each probe can move freely and at high speed, achieving an astonishing inspection speed that is world-class in standard. By using the upper and lower flying probes simultaneously, a combination inspection of up to six probes allows for simultaneous contact inspection at both points on the top and bottom sides of the substrate. This significantly expands the inspection range and further accelerates inspection time. It is equipped with a wealth of features and boasts world-class standards in speed and positioning accuracy. ★You can bring your substrate to our demo room at our Okayama headquarters for evaluation testing★ We can conduct a series of tests including the creation of inspection programs, inspections using actual substrates, and summarizing evaluation results.

In recent times, there has been a growing interest in infection control measures and facility hygiene management. Our company offers non-contact sensor products that are recommended for commercial facilities, food factories, and nursing and caregiving facilities. 【Sensors for Automatic Doors】 ● Light Touch Sensor HA-T401 … When you wave your hand in front of the automatic door, the sensor detects the movement and opens or closes the door. This is recommended for making doors with touch switches non-contact. ● Hand Wave Sensor PF-R5, PF-U2, DHS-1 … Opens and closes the automatic door by waving your hand in front of the sensor. ● Foot Switch PF-01S/01D/03S/05 … Opens and closes the automatic door by placing your foot in the opening. 【Access Control System】 ● Face Recognition + Unmanned Temperature Measurement DS Series … Allows for face recognition along with mask detection and body temperature measurement simultaneously. ● Automatic Disinfectant Spray Dispenser PHW-03B … Automatically sprays disinfectant when you wave your hand in front of the sensor. 【Nursing and Care Sensors】 ● Infrared Bed Exit Sensor "Just Place It Pole-kun" … This bed exit sensor is installed next to the bed and notifies via nurse call when the subject enters the detection range. ◎ For more details, please download the catalog or contact us.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, particularly at entrances facing sidewalks or roadways, there is a risk of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "sensor" + "controller" + "switching power supply (24V)" + "LED rotating light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.
