Invisible things and items madeby a chemical manufacturer.
The chemicals we manufacture make an invisible micron world.
They are used in invisible places, but are indispensable chemicals for fabricating
substrates and they create an invisible interface between substances.
In addition, in order to aim for the best product quality and increase reliability,
we invest about 10% of our consolidated sales in R&D, and are particular about
raw material procurement, manufacturing processes, and shipping methods thatcustomers do not see.
And we continue to expand our circle of trust around the world and contribute topeople's lives.

In growing our business, we have placed research and development at the core of ourcompanyʼs management, and feel it is our mission to provide the chemicals our customers
request when offering innovative products to society. At the same time, as atechnology-partner, we continuously work to create new chemicals that will trigger ourcustomerʼs enthusiasm when developing their roadmaps for future technologies. Thisapproach has led us to closely observe trends in the electronics industry, to try and find out
the demands of our customers and to tirelessly advance our research and development as wesow the seeds of the future.
We go way beyond simply providing chemicals, our added value is based on a transfer oftechnological knowledge thus technical support and keeping our partners informed on theu p - a n d co m i n g t e c h n o l o g i e s i s e q u a l l y i m p o r t a n t . A s s u c h , we co n t i n u e t o s e r ve a s acompany that offers unwavering customer satisfaction with strengths in providing both thestate-of-the-art tangible, our chemicals, as well as the intangible related technologies.
More recently, we have set our sights on all of the changes occurring during the upcoming
fourth industrial revolution, symbolized by the development of the “Internet of Things” and“Artificial Intelligence”. In this light, we are enhancing our corporate structure with new
business units that adopt the technologies we have acquired through the development ofchemicals for PCB fabrication in entirely new fields of application.
Just as before, these new businesses will unfailingly provide high-quality products andservices with substantial added value, thus contributing to a brighter future for our society.

acquired over the years.
Our chemicals create the hidden "surfaces" that form
the boundaries between metal and resin.
In particular, we excel at adhesion reliability, one
important aspect of interfaces during precision electronic
Circuit patterning. Our chemicals dissolve and modify metal
surfaces to provide for an enhanced adhesion between thevarious layers which compose a Printed wire board.
In this way, our technologies that create these interfaces
have played a role in evolving and advancing electronics.

From Procurement to Shipment

01 Blending

02 Final Inspection

03 Filling

04 Shipment∙ Every aspect from raw materialdelivery to receiving
inspection and use in products
is recorded and controlled∙ Barcode control is used tospecify and measure therequired weight of theingredients to be blended∙ Barcode control is used to feed
the ingredients into theblending tanks∙ Chemicals are checkedagainst MEC Groupstandards∙ Finished chemicals arechecked for performance∙ Chemicals that have passed
final inspection are filled
into containers∙ Chemicals are stored in ourwarehouses until shipment∙ Containers are washed after
use and reused∙ Barcodes are used to manage
the history of lot numbers
and shipment destinations,etc.
∙ Samples for all chemicals are
stored for a specific time

About Quality Management

13

Traceability Management

Product Management SystemTo prevent human error and strengthen
traceability and quality management, wehave adopted a "Blending Control System"and "Shipment Management System." We
have also taken steps to convert blending
operation management to an online system,
prevent material input problems, andautomate record keeping for production andoperations. In addition, we manage thehistory of each customer order from raw
material ordering and receiving inspection
to shipment.

When a chemical is prepared for shipmentfrom one of our warehouses, we manageand record the history by logging the detailsof the shipment instructions, including
shipment destination, product and numberof units.
