KCE Electronics Public Company Limited (KCE) was established on Nov. 5, 1982. The Company listed on the Stock Exchange of Thailand in August 1988, and converted its status from a limited company to a limited public company in December 1992. The Company’s core business is the production and distribution of printed circuit boards (PCBs), under the “KCE” trademark. .

Detail of the Products

PCB (Printed Circuit Board)

Printed circuit boards (PCBs) are fundamental components in a wide range of electronic products, serving as the foundation for electronic circuits. All electronic devices used in everyday life include one or more PCBs. These boards contain interconnected copper traces that provide pathways for electrical signals, enabling the mechanical support and interconnection of electronic components.

PCBs are composed of two main parts: the substrate (or base) and the electrical conductors. The substrate is a thin layer of insulating material, typically made of woven fiberglass fully coated with epoxy resin. This substrate material possesses excellent thermal, mechanical, and electrical insulation properties, making it ideal for various electronic applications. The copper conductors are either etched or plated onto the substrate, forming pathways for electrical signals between components.

KCE Electronics Public Company Limited (KCE) specializes in the following PCB products :

1. Double-sided plated-through-hole PCBs
2. Multilayer PCBs: Available with 4 to 24 layers of copper traces.
3. Semi-flex PCBs: These multilayer printed circuit boards feature areas that are thinned by depth routing, allowing them to bend easily for better fit within enclosures.
4. HDI (High-Density Interconnect) PCBs: Advanced multilayer boards with higher circuit density, characterized by fine lines and spaces, laser-drilled via holes connecting layers, and buried vias embedded within the board. HDI technology is essential for cutting-edge PCB designs.

PCBs find applications in various industries, including automotive, industrial equipment, telecommunications, consumer electronics, medical devices, mobile phones, and computer equipment.

Given that PCB production requires advanced technology and adherence to industry standards, the Company is committed to continuous improvement in quality control, production technology, and operator skill levels. The Company has expanded its production capacity and appointed sales representatives in various countries to meet the growing global demand for PCBs.

Prepreg & Laminate

Thai Laminate Manufacturer Company Limited (TLM) is a manufacturer of Prepreg and Copper Clad Laminate or Laminate. Both Prepreg and Laminate are the primary materials for manufacturing Printed Circuit Board or PCB. PCB is the main part to be used for manufacturing electronic parts in automotive, telecommunication network, industrial electronics, medical equipment, consumer products and so on.

TLM production consists of 2 parts : Prepreg Process and Lamination Process

1. Prepreg Process

   Glass fabric is treated with the varnish solution, mainly consisting of epoxy resin. The treated fabric is then heated at 170 to 200 degree Celsius around 1 minute until the solution undergoes polymerization, creating the solid glaze that coats to the fabric. It is produced in a roll form and stored in the cold room at the controlled temperature and humidity. The rolls of Prepreg are ready to be distributed and delivered to clients. A certain portion however, is cut to sheets to be used as a raw material in the manufacture of laminate.

2. Lamination Process

   Prepreg is cut to the proper sizes and stacked after designed thickness of dielectric. They are loaded to the lay-up machine in the clean room. Copper foil is attached at the top and bottom of the Prepreg sheets and each set is separated by a caul plate. The stack of sheets are pressed in the vacuum hot press at 170 - 200 degrees Celsius in the period around 2.5 to 3 hours for laminate curing. After that it is cut to size and trim before being packed for delivery to customers.

Chemical

Chemtronic Products Co.,Ltd.’s main products are Copper Sulphate and Tin Oxide which use the raw materials from the recycle PCB spent and Scrap. The Copper Sulphateare applied for feed mill, fishery and fertilizer industry with the certificate of FAMI-QS, Department of Livestock Development and Department of Fisheries. For Tin Oxide is applied as raw material for tin related products.

CTC Chemical Co.,Ltd. has PCB etching chemicals manufacturing. The main products are alkaline etching chemical and tin stripper chemical.

Manufacturing Facilities

The Company and its subsidiaries have factories and offices for manufacturing as follows:

Policy and Business Overview

KCE Electronics PCL and its subsidiaries are involved in the manufacturing and distributing of printed circuit boards (PCBs), which are the foundation component for a wide range of electronic devices. Its key customer base includes manufacturers of automotive electronic equipment, telecommunication devices, computer networks, industrial equipment, medical equipment and consumer product. Almost all of the Company's production is for exporting worldwide; Europe, United States of America and Asia.

The Group's operational policy is mainly committed to achieving the excellent in manufacturing capability, by initiating various strategies to obtain a better quality product, at a lower cost. The Company continues to seek opportunity to increase profit, by introducing new technologies in production and fully utilize current assets to its utmost benefits, which will be resulted in reaching the maximum efficiency level. Another important policy is the commitment in keeping a long term relationship with its customers by providing the most valuable service- the reputation of quality product, that gain trust from customers ever since. In addition, the company has a policy that focuses on responsibility towards stakeholders, including society and the environment as a whole.

Regarding the management of operations, the Board is responsible for the determination of strategies and key policies. CEO, who is policy responsible arranged a meeting between CEO and Managements annually, for the purpose of communicating such strategies and setting up the operational objectives (KPI) for the factory as well as for each section of operation. Management of each section then continued to arrange separate meetings to further communicate the strategies and targets down to employee level. During the year, the targets were seriously monitored by comparing actual results with the planned KPI. Managements also regularly reported the operation results to the CEO in the monthly Management meeting. CEO then summarized the operation results for the strategies and reported to the Board in each quarter.
