Does your inspection strategy include Reflow Process Inspection?

Do you need better defect analysis? Combine reflow data with your SPI and AOI data for true defect data analytics.
Without RPI you don’t have the complete picture!

KIC reflow process inspection

There is SPI for Screen Printing, AOI for Pick and Place, and there is RPI for the Reflow Oven.
KIC’s RPI provides production reports such as yield analysis, DPMO, Pareto Charts, Cpk and much much more.
The RPI is an automatic system that, once programmed, works in the background without any operator involvement.
Its capabilities include:

  • Provides process deficiency information to help correct defect issues quickly
  • Shares all pertinent process and production data in real-time
  • Automatically profiles each and every PCB
  • Provides instant alarm for out-of-spec situations
  • Automatic SPC charting, including Cpk
  • Process traceability down to individual PCBs
  • Prevents human error such as production of the wrong PCBs or wrong oven recipe settings (bar code required)

The KIC RPI improves quality and throughput, and is universally applicable. Inspection is independent of the oven model, personnel, PCB types and production site.

Koh Young collaborates with Mentor to further simplify inspection system programming

Seoul, Korea — Industry leader Koh Young announces it has joined forces with Mentor, a Siemens business, to deliver an enhanced programming solution, which will benefit the printed circuit board assembly market. Building on the AI-powered Koh Young Auto Programming software (KAP), Mentor integrated its Valor™ Process Preparation Software to further simplify Automated Optical Inspection (AOI) programming and reduce production costs by saving time through the implementation of Mentor’s Open Product Model.

“The synergy between our companies has resulted in an outstanding solution that is designed to help reduce time to market and improve production quality across the line,” said Mr. JD Shin, Chief Sales Office for Koh Young Technology. “We are especially excited about this particular collaboration with Mentor, because it was in direct response to the voice of the customer. The partnership highlights the benefits customers can realize when two suppliers work together towards a common goal. It was a win-win for everyone.”

The enhanced software eliminates the need for CAD and Gerber files, which saves time be eliminating the efforts by a programmer to locate, upload, and manipulate these product files. The new solution reduces programming time by blending several elements together that automatically creates the necessary AOI programming files.

One of the elements Koh Young integrated from Mentor includes the Valor Open Product Model (OPM). Introduced in 2018 by Mentor, OPM is an open data assembly format structured in XML, which focuses on the printed circuit board assembly model (PCBA) and the associated manufacturing process plan. OPM is a solution for the open exchange of process engineering information between disparate machines and processes. In the same way that ODB++ works for design data, OPM is the answer to the need for flexibility that Smart Industry 4.0 factories demand.

A second element that is now part of Koh Young software, it the extensive Valor Parts Library (VPL) database from Mentor. Comprised of over 35 million component manufacturers part numbers and package geometry definitions, Valor Process Preparation software uses this information to fully automate the creation of new parts and packages for use in inspection systems and mounters using its “Auto-Generation” rule methodology.

Combining a single assembly format file output like OPM and a standardized machine package library from VPL, the manufacturer minimizes program variations between machines like inspection systems and component mounters. This improved programming approach can eliminate human error and variation, while significantly reducing NPI programming time. Additionally, OPM is generalized so it is interoperable among various systems and easily enables moving production between lines and—more importantly—factories across the world.

 “This joint programming project was just the first step in an expanded collaboration to improve the PCBA manufacturing experience for our customer,” said Mr. Rick Esposito, Director of Valor’s Processing Engineering Product Line. “When industry leaders collaborate, remarkable solutions result. We are excited about this relationship and the future together.”

Remembering Tom Waltuch

Remembering Tom Waltuch
20-05-1944 – 19-07-2020

It is with great sadness that we share the news of the passing of Tom Waltuch, Sales Manager and Managing director of W&S Benelux BV from 1983 till 2015. 

This wonderfully charismatic man passed away peacefully in the early morning of Sunday the 19th July, surrounded by his family. Our thoughts and love are with his wife Conny and daughters Simone and Danielle and their families.

We will always remember Tom’s integrity, honesty, drive and full commitment to W&S and his  team.  He was a true salesman , he loved the contact with customers and showed genuine interest in person and product,  yet not losing sight of the commercial interest in his personal approach.

His creed in life was ‘ who does good, meets well’. With rock-solid confidence that this belief was (is)  ultimately the most important, he gained  trust from many customers. We will remember his insight, forward thinking, and his very big heart.

The world is a sadder place without him. He will be missed terribly by his family and friends and all of us at W&S Benelux BV.

Welcome back Ton Luijten

Ton Luijten

We are happy to announce that since June 1 Ton Luijten is back in the W&S team.

Ton already has a history at W&S, he previously worked at our company from 2007 – 2018. During that time he gained expert knowledge about most of our products and technologies. Ton is a well-known face for most customers.

We are happy that he is back and wish him the best of luck in his work.

Trust is good, but a “Benchmark Board” is better

EPP & Koh Young present Benchmark board webinar

May 27, 2020 / 10:00 a.m. – 11:00 a.m.

Koh Young benchmark board ver.09

Your current product, which you use for a machine demonstration or an evaluation, will not necessarily reflect the requirements of the future. The manufacturer’s demo board usually shows “state-of-the-art” technology. However, this in a manageable form. This means, it will not reflect the production reality. And now we are already with the requirements of a “real” benchmark board. It should be close to production reality; it should include current and future technologies and it should show inspection limits.

Koh Young has been developing benchmark boards for many years, which are now being used by a wide range of manufacturers and users. The webinar will give you an introduction to the topic of benchmark board and benchmark board design. Get to know ways of differentiating 3D measurement concepts and learn how to correctly classify the statements in the glossy brochures.

Koh Young delivers the 10.000th inspeciton system

A special project at KCS Elektronica

KCS Electronics assembly is located at the Kuipershaven in the historic center of Dordrecht in a characteristic harbor building (built around 1700). Behind this historic facade you will find a modern electronics manufacturing company.

Following a long range of interviews and research, KCS decided in November 2016, to significantly modernize SMD production in collaboration with W&S.

To achieve this goal, KCS decided to invest in assembly equipment, test equipment and a comprehensive software package to be able to produce the highest quality with maximum flexibility.

The following process steps were brought to the latest state of the art:

  • Pick & Place:
    • Juki Flexline KE3010 and KE3020 Pick & Place machines including matrix tray changer.
    • Juki Intelligent Shopfloor software for control of the Pick & Place machines combined with the advanced intelligent feeder system IFS-NX.
  • Reflow:
    • Heller 1707MKIII reflow oven with 7 zones on top and bottom side of the PCB.
  • Automatic Optical Inspection:
    • Koh Young Zenith 100% 3D measuring machine for AOI inspection.
  • Program Preparation / CAD Conversion:
    • Siemens – Unicam NPI software for fast and error-free conversion of CAD and BOM data as provided by the customers.

Mission Impossible?

Even though at W&S we do have quiet some experience with interesting installations of equipment in special buildings, a 17th century canal house with all the constraints was an interesting project for us.

The free space between the front of the property and the (unshielded) water of the harbour was about eight meters, this was a nice challenge for the forktruck driver. Inside the building the production floor where the new equipment was going to be placed consisted of three different levels. Also this meant a big challenge for the movers.

To get the reflow oven at the planned location, two height differences had to be bridged, and two door frames had to be temporarily removed. After these preparations we had an opening where the four meter long machine had to pass through with a clearance of less than 2 centimeters on the side.

Not much space between the building and the harbour

It fits, we measured correct 😉

AT the location where the Pick & Place machines are placed, there used to be an indoor swimming pool. Before arrival this swimming pool was completely filled with hard foam, and covered with a top layer of concrete.

After these preparations the surface was sufficiently stable for the very high precision Pick & Place machines.
(At these moments we are very happy with the exceptionally stable frame of the Juki machines).

Internal transport of the Juki machines was easy in comparison with the Heller oven.

All equipment arrived safely at the right location

After transportation and installation of the oven and the pick & place machines, placing the Koh Young AOI machine was easy to accomplish.

Mission Completed!

The result:
Thanks to the perfect collaboration between the highly professional movers, the (almost complete) KCS team and the W&S service team everything was in the right place within 2 business days and shortly after this KCS could start production with the new equipment.

The Heller oven installed and running.

The Juki Pick & Place line in full production

Meanwhile, KCS employees are already getting used very well to the new equipment and many high quality products are produced every day.

We wish KCS good luck and many years of worry-free production with the new equipment.


Through the involvement, knowledge and empathy during preparation,
W & S Benelux has managed to literally deliver a tailor made solution to KCS.

The technical support from W & S Benelux enabled us to learn the software
and equipment functionality in a short period of time.

With the new JUKI line, KCS produces most advanced electronics products
with minimal lead time.
