Takaya APT 9411

FIXTURELESS TESTER APT-9411 CE/CJ

The APT -9411 series is a flying probe test system for detection of manufacturing defects on printed circuit boards using 4 high speed independently moving probes, thus removing the requirement for a conventional bed-of-nails fixture. In 1987, Takaya pioneered the concept of a flying probe tester combining advanced test techniques and precision mechanical systems. Since then, Takaya, as market leader for flying probe test systems, has focused its research and development resources on getting to market fast with the new product, to meet rapidly changing technological requirements and changing user needs.

The APT -9411 series is the latest generation of tester that integrates the probe movement and positioning control technology and the measuring techniques that Takaya has accumulated over many years. In this model, we have achieved the highest positioning accuracy, the highest inspection speed and the best test coverage as well as extended AOI functions and many other features.

Takaya has an installed base of more than 1,500 flying probe test systems in major electronic manufacturing and EMS (Electric Manufacturing Service) / CM (Contract Manufacturing) plants in over 40 countries. Designed by Takaya with worldwide acclaim and confidence, the APT-9411 series will make a big contribution for your development in the EMS & CM business, as well as helping you to reduce your operating costs and improve quality levels in a wide range of your SMT products.

HOW TAKA YA FLYING PROBER ADDS VALUE TO YOUR COMPANY

  • LOWERING TESTING COSTS

Bed-of-nails are commonly used for testing PCBs using ICT/MDA techniques. Usually, it takes one or even several weeks to manufacture the bed-of-nails and the associated costs are high. Consequently, when ICT/MDA is used for low and medium volume production such as prototyping and NPI (New product introduction), unit test costs are very high and valuable time is lost waiting for the manufacture of the
bed-of-nails. This results in reduced profits for your board assembly business. Since the APT-9411 series utilizing 4 high speed independently moving probes doesn't require conventional bed-of-nails and begins to test right from the beginning of the board assembly by just creating the test program, the tester is ideally suited for high board mix prototype applications as well as low and medium volume production runs.

  • LOWERING COSTS OF ENGINEERING CHANGES

When circuit design changes result in shifting test points and/or circuit patterns, the bed-of-nails for the ICT/MDA must be remanufactured or
modified, which requires not only unnecessary costs but also introduces extra delays. However, the APT-9411 series can promptly respond to circuit board design changes by simply correcting probing positions in the test program. This is one of the important benefits of using the APT-9411 series.

  • REDUCING PERSONNEL FOR VISUAL INSPECTION

ICT/MDA is unable to inspect bypass condensers and connectors for reasons concerned with the circuitry and/or electronic capabilities. Such devices normally require visual inspection. However, automated optical inspection (AOI) added to the APT-9411 series enables you to inspect components that are difficult to measure electrically, thus enhancing test coverage and reducing visual inspection cost.

  • EASY ACCESS TO FINE-PITCH SMT DEVICES

The APT-9411 series ensures high precision probing contact and utilizes its AOI function to correct probing co-ordinates automatically based on actual positioning errors on each board. With these features, test points of less than 2Smil (O.6Smm) pitch or the contact lands of less than 20mil (O.Smm)in diameter are accessible with accuracy by the 4 moving probes. This helps reduce your OFT (Design for test) work and allows fault detection of fine-pitch SMT boards where no contact lands are available for bed-of-nails. Therefore, the APT-9411 series is best suited for the inspection of the SMT boards

  • IIQUALITY IMPROVEMENT OF PRODUCTION LINES

The APT-9411 series assumes the role of improving the quality on your entire mass-production assembly line where test time is restricted. The best practical example is a periodical sampling inspection for possible programming errors or careless mistakes in component settings on the pick & place machines.

  • PROTECTING THE GLOBAL ENVIRONMENT

Preserving and disposing the bed-of-nails costs time and money. In addition, as the bed-of-nails is mainly composed of metal and resin, it's
expensive to dispose of as industrial waste in order and not to affect the global environment. In contrast, the APT-9411 series doesn't cause these expenses and doesn't produce any industrial waste. That is, the APT-9411 series is eco-friendly and contributes to environmental protection.

  • RESPONDING TO CHANGING NEEDS

The APT-9411 series has a full range of options to extend its capability according to the needs of a great variety of users. In addition, the
APT-9411 series responds to the changing needs of inspection, as electronic components progress, because it is designed to easily integrate other measurement instruments. The APT-9411 series, with its integrated expandability, is a new-generation board tester that can serve you for many years to come

HIGHLY-ADVANCED MECHANISMS CAPABLE OF THE WORLD'S HIGHEST POSITIONING ACCURACY AND ULTRAHIGH-SPEED TEST

  • STRONG AND RIGID XY STAGE

We drew a conclusion from the long history in developing flying probe testers that the most important parts for the positioning accuracy of the moving probes is the XYstage in the mechanical section. Because, even if the various precision components including the motors, the slide rails, etc.. are excellent in terms of accuracy and/or performance, the XY stage that deforms during time inevitably leads to inaccurate probing contact. Accordingly, the tester's XY stage, crucial to stable and accurate probe contact, is made of highly polished native granite, whose surface accuracy remains unchanged even after years of prolonged use. Therefore, the APT-9411 series that remains almost unaffected by extreme environmental conditions, its age and use and the movement of installation location ensures high precision and stable probing contact in order to keep testing SMTboards for a long period

  • SUPERFINE MECHANISM

As the mechanical section in the APT-9411series is designed based on a thorough analysis of structure, vibration and material, the tester is able to balance the competing goals of probe movement speed and positioning accuracy. In addition, the tester is extremely durable and is stable in the XY positioning contact due to the use of high-precision components in the actuators, and thereforealways gives the best performance.

  • FAST PROBE MOVEMENT

All the XYZ axes combined with AC servo motor that has a superior rotating characteristic are controllable on high speed and smoothness. In addition, the APT-9411 series cuts down the stabilization time for the probe's positioning and inhibits probe vibration occurring when they come to a standstill, due to the servo drive system employing the latest digital control technology. The APT-9411 series attained fast probe movement with accuracy to test PCBs in the shortest times.

  • REDUCING TEST TIMES

The APT-9411 series realizes high-speed inspection using 4 independently moving probes and 2 fixed bottom probes. So, the
combination measurement using these 6 probes that implements double-digit numbers of test steps quickly dramatically cuts down test
time. In addition, the tester incorporates an excellent algorithm to rearrange test steps and other features to optimize the flying height
according to each component, which will result in faster probe movement.

  • HIGH PRECISION PROBE

The probes have surprisingly fine clearance of less than lO,um between the plunger and the housing to simplify test access on very little contact lands. In addition, the clamper mechanism and the lifting base for the support bars help the boards not to have a downward curvature and thus ensuring reliable probing contact. These factors also help detect faults on today's leading edge SMT products where are only small contact lands remain.

  • FUNCTIONAL DESIGN

The ergonomic design to reduce the strain on the operator ensures an excellent operational performance and deadens distracting noise during operation. In addition, the APT-9411 series requires minimal floorspace and no air supply for standard operation.

  • LAN-BASED DATA MANAGEMENT

The software allows use of versatile function such as network system and multi-taskingavailable in Windows®XP.Test results and the measurement values on each board are output to network computers and/or a repair station in real time via LAN. This facilitates your quality management and repair work
