JUKI takes over Sony EMCS and enters AOI and SPI Market

03 February 2014 - JUKI Corporation and Sony EMCS Corporation, a subsidiary of Sony Corp. Japan, united their currently individually run businesses in the range of assembly technology and related businesses under “JUKI Automation Systems Corporation”. With the integration of Sony EMCS newly developed AOI and SPI systems have been added to the JUKI portfolio. With these new systems JUKI introduces a complete process quality control for high performance lines as well as for high flex lines.

JUKI now announced the launch of the RV-1 PWB inspection machine, which significantly improves inspection accuracy and speed with both automatic optical inspection (AOI) and solder paste inspection (SPI) functions. RV-1 inspects component mounting failures and solder printing failures to prevent defective PWBs from going on the market. This machine is equipped with “Clear Vision Capturing System” to correctly detect a failure at high speeds even for high-density PWB, used in devices such as mobile terminal.

 To inspect a PWB, the machine will compare the actual PWB image data with the data programmed in advance to determine whether the PWB is correctly produced or not.  It uses “Clear Vision Capturing System” as an illumination device for shooting a PWB, and is equipped with 270 mm large-diameter high-brightness white LED 3-ring light and coaxial light. These lights allow the machine to capture extremely clear images for any kind of items, so that the machine can drastically reduce false calls (erroneous decision of a good PWB as a defective) and time loss required for recheck. Additionally, a twin linear motor, high-speed data transmission of CMOS camera and image processing library enables high-speed image shooting at 0.14 sec/frame to increase the speed of inspection significantly.

 3-D images synthesized from images shot with the “angle camera” can be displayed for a final visual check so that the operator can determine whether the PWB is correctly produced or not. “Central Operation Control” allows one operator to check inspection images from two or more production lines, in order to streamline the inspection process and prevent variability of judgments among each operator. As for programming, all you have to do is to paste a template created in advance, then the inspection data will be generated automatically; the operation will be easy even for beginners.

RV-1 is equipped not only with the AOI function, for inspecting the placement condition before and after the reflow, but also the SPI function for inspecting the PWB after solder printing. These functions are applicable to a variety of applications, and can flexibly correspond to changes of production line.  Same operation method can be adopted for both functions, so that the programming and operators’ education can be performed effectively.

Due to recent trends in high and multi-functionality of smart devices such as smartphones, automotive Engine Control Units (ECU), medical devices and digital consumer electronics devices, the size of components have been reduced further, and density increased further.
