Koh Young Announces Sale of 1000th 3D AOI System

KY-Zenith-1000SEOUL, SOUTH KOREA – Koh Young Technology announces the delivery of their 1000th 3D in-line Inspection AOI system, a Zenith model; the system was sold to Mando-Hella Electronics Corp. (MHE), located in Songdo, Incheon, South Korea. Mando-Hella is recognized as leading the trend in advanced electronic technology in the Korean automotive market.

In making the announcement, Dr. Kwangill Koh, CEO of Koh Young, said “The delivery of our 1000th in-line AOI system is a significant milestone for Koh Young Technology since we’ve started introducing 3D AOI from 2010. We are honored to have Mando-Hella Electronics deploy our Zenith systems to optimize their electronics manufacturing process. My thanks go out to the entire Koh Young family whose dedication, perseverance, and commitment to excellence and customer satisfaction have made this possible.”

In announcing their purchase, Keon Lee, Plant Manager of Mando-Hella Electronic in Korea, said, “We chose the Koh Young Zenith 3D AOI to increase product quality by using quantitative 3D measurement to overcome the shortcomings of 2D AOI technology. We are implementing Smart Factory setup configuration, helped in part by Koh Young’s KSMART Remote Monitoring System (RMS), part of our Industry 4.0 realization. We also expect ongoing process improvement through the integration of closed loop process control between our Koh Young SPI systems and our Mounters.”

MHE was the first company to introduce various state-of-the-art electronic products into the Korean market, including digital type torque and angle sensors, POWER Pack, a core control unit of electronic power steering systems (EPS), and radar, the brain of advanced driver assistance systems (DAS).

The Koh Young Zenith 3D AOI system measures the true profilometric shape of components, solder joints, patterns and even foreign material on assembled PCBs with patented 3-dimensional measurement, overcoming the shortcomings and vulnerabilities of traditional 2D AOI. Zenith uses 2D and 3D information for better visualization of the components and solder joints. This ability allows a true comparison with the IPC-A-610 standard for inspection. Thus, the acceptability of the solder joint is without question. Zenith is the first true 3D AOI system ever developed.

Agile Process Management is enabled with Koh Young Technology’s KSMART Remote Monitoring System (RMS), a portal to Industry 4.0 realization. KSMART RMS shares crucial Information such as yield data, machine condition, and defect data from different SPI and AOI systems to one location. Fewer engineers and operators are required for real-time multi-line management, which is now easier and centralized for higher productivity. Process status and analysis from individual production lines can also be managed from a remote location.

LPKF Launches Entirely New Flex Drilling & Cutting Laser

LPKF Microline 5000Electronics manufacturing equipment manufacturer and laser specialist LPKF Laser & Electronics AG is launching an entirely new laser drilling and cutting system specifically tailored to the needs of the flexible circuit industry.

The LPKF MicroLine 5000 is a UV laser based flex drilling system with a large working area of 21” x 24” and is available in two different laser power classes, depending on customer needs for various substrates and thicknesses. The system is equipped with precise process monitoring systems as well as intelligent vision systems for fiducial recognition and alignment.

Nils Heininger, Senior Vice President at LPKF explains, “We believed that the flex drilling market was underserved with the solutions currently existing in the marketplace in terms of speed, quality and cost. With LPKF being a specialist in laser based circuit processing, we felt we can do better and serve the industry with a modern laser system that is very fast and delivers superior quality drill holes at a very low cost of ownership.”

Although the system is mainly focused on high-speed drilling of both blind vias and through holes, it is equally effective for contour cutting of flexible circuits. With a small laser beam spot size of only 20 μm, it allows for precise cuts of intricate flex circuit geometries. The laser system is operating in the UV wavelength allowing it to drill and cut delicate substrate materials with a minimal heat affected zone. For added flexibility, LPKF’s MicroLine 5000 can also be configured for reel-to-reel handling of flex substrates.

Koh Young 3D SPI – Closed loop to printers

A new Koh Young brochure is available with the latest information about the “Closed Loop”  functionality for the SPI systems and major screen printers.

Closed Loop function

The Closed Loop option is a method of continually monitoring and adjusting a process to maintain a particular target value of outputs. The Closed Loop option, used between screen printers and solder paste inspection systems, uses inputs from an automated Solder Paste Inspection (SPI) system to control print parameters and actively prevent defects, instead of just identifying defects.

BONO Success for Kester products

2015-08-28-kester-news-bono1Recently, Kester submitted commercial products of NP505-HR, NF372-TB, and 985M to a third party laboratory for Bono testing. All these Kester products passed at a level that indicated no corrosion in the residues.

What is the Bono test?

SIR and ECM tests have been recognized by IPC as a way to evaluate paste or flux residue corrosiveness after reflow, the Bono test was developed and implemented in some French companies as an extra qualification criteria.
The Bono test also quantifies the corrosion, unlike current SIR or ECM tests. And in addition to characterizing solder paste residues, the Bono test can be performed for wave soldering fluxes, repair fluxes, and tacky fluxes using the same method and same board.

Please contact us for updated product information and datasheets.

Bergh Hybrid Circuits expands production capacity with a new Juki KE-2080

BHC logoAt Bergh Hybrid Circuits the management team has it’s own approach regarding their production facilities. This is clearly visible in the SMT production department, BHC strives to be an extremely reliable supplier and this results in a very high customer satisfaction.

For the SMT production BHC has selected JUKI equipment for the very high reliability and accuracy and the lowest cost of ownership.

When the production requirements were growing rapidly in 2012 BHC started to renew and expand the SMT line. The first steps were the purchase of a new JUKI KE-1070 machine together with a new JUKI GL screen printer. This line was completed later that year with a Heller 1707MKIII reflow oven and automatic loaders and unloaders from Nutek.

Overview of the SMT production department with 2 complete lines

After this high quality new line was in full production the company continued to grow. New customers and new orders required even more production capacity, so it happened that in the first half of 2013 we were discussing with the management of BHC about how to double the capacity for SMT production.
After some calculation and simulation work it was decided to expand the production with a complete second line. For this new line a JUKI KE-2070 was selected and again a Heller 1707MKIII was ordered so products could be easily moved between the lines.

After running these two lines with full production for approximately 6 months it became clear that the growth at BHC was not finished. The weak economy in Europe did not seem to border BHC at all and they just keep on growing. In the second quarter of 2015 we were having a meeting again about increasing production capacity and a wider component range.

For some of the new products larger and higher components needed to be placed, therefore BHC selected a JUKI KE-2080 as an extra module in their first line. The new KE-2080 was delivered at April 22 and is already running in full production. With this increase in capacity BHC should be ready for the next year, or…..?

We are very proud that BHC has chosen our equipment and services for their SMT production lines and we wish the BHC team lots of success with their new equipment.

“ Our latest new production line is an investment in our future. The new production line of Juki will enable BHC to serve its customers faster and more flexibly than ever. We believe the new Juki 2080 supplied by the excellent service of W&S will be a contribution to the success of BHC.“

Belgian high-end automotive supplier C-MAC relies on JUKI screen printer

As a producer of high-quality circuits in hybrid technology for automotive, medical engineering and industrial automation C-MAC relies now on screen printers from JUKI.

C-MAC has two production plants. One is located in Ronse, Belgium and the second in Sherbrooke, Quebec, Canada. Each site offer automated production lines on the highest level for specialised electronics with enormous requirements for precision and reliability even under harsh conditions.

201-01-news-C_Mac_picture_webSince their introduction in early 2012, the JUKI screen printers have proved their selves to be highly successful in the market. In a little more than one year JUKI has sold more than 100 screen printers in Europe and the US. The printers either replaced existing units in the lines or were sold as a part of a complete JUKI production line offer according to the line solution concept. A fast delivery by JUKI, easy operation and maintenance as well as high printing accuracy convince even such highly specialised customers like C-MAC. The units manufactured by C-MAC have to function faultlessly even under harsh ambient conditions. This can only be achieved by an extremely high production quality. C-MAC is already relying on JUKI pick- and place units for years. Now they integrate their first JUKI GL screen printer in the line.
