ABOUT

PCB Manufacturing

EMS Printed Circuit Board Manufacturing

Printed circuit board manufacturing is the process of creating the core foundation of electronic devices.
First, a circuit pattern is formed on a copper foil-covered board based on the designed circuit diagram.
This involves the process of transferring circuit patterns onto a substrate using photolithography technology.
The unwanted copper is then removed, leaving only the desired pattern.
Holes (vias) are then drilled for component mounting, and the board is chemically or mechanically treated to improve durability and signal transmission properties.
Finally, the process of mounting the components on the board (mounting process) is carried out.
This completes the electrically connected circuit. High-precision measurements and inspections are carried out during the manufacturing process to ensure strict quality control.
Printed circuit boards are essential components in a variety of electronic devices, including smartphones, computers, and home appliances.

Our Services

Design and Manufacturing
We offer printed wiring boards suited to your application, including 5G communication compatible, multi-layer, build-up boards, and high frequency, high density, high heat dissipation, and large current boards.
We are a company that specializes in the design and manufacture of printed circuit boards, which are basic components of electronics.
Although we don't see printed circuit boards in our daily lives, they are essential components in making computers and electronic devices.
The quality of the printed wiring board, which can be said to be the brain of the product, is the key to the product.
We manufacture high-quality printed wiring boards that can be used safely and without problems, and do business with companies in a wide range of business fields, including industrial equipment, communications, and medical equipment.
We will proactively pursue new technologies to understand customer needs and expectations and provide them with high-value-added products in order to build even stronger relationships of trust.

Procurement
Supports small to medium quantities, a wide variety of products, and short delivery times
We offer high-quality domestically produced printed wiring boards starting from a single piece.
We work with 10 domestic partner factories to meet customer needs, and can not only provide short-term production, but also meet requests for high-mix, low-volume production and mass production.
We are capable of manufacturing a wide variety of printed wiring boards, including multi-layer boards, build-up boards, high heat dissipation aluminum-based boards, and high-frequency boards.
Our partner factories ensure stable production and high-quality products through integrated domestic production.
EMS Printed Circuit Board
Acceptance inspection
We strive to establish an appropriate acceptance inspection system with the aim of stabilizing quality and streamlining the manufacturing process.
We mainly carry out incoming inspections and source inspections to ensure that purchased materials and electrical and electronic components meet specific standards and requirements.
We prevent defective products from entering the factory. We manage the inventory of purchased materials and collect materials for each model, and deliver them to the manufacturing site on time and input them into the mounting site.
After manufacturing, when the parts are returned, we will take an inventory and inform you of the actual number.

DETAILS

Detailed Service

type 01
Single-sided paper phenolic board
This is a printed circuit board that uses a paper-based insulating material impregnated with phenolic resin, with copper foil attached to only one side.
Because of its low cost and excellent processability, it is widely used in home appliances and simple electronic devices.
It is also popular as a general-purpose board for mass production.
type 02
High speed and high frequency
This is a printed circuit board designed to accurately transmit high-speed and high-frequency electrical signals.
It features a structure that uses low dielectric constant and low loss materials to minimize signal distortion and noise.
It is often used in communication equipment, radar, 5G equipment, etc.
type 03
Build Board
It is a type of multilayer printed circuit board, with a structure in which inner and outer layers are stacked and connected in stages.
High-density wiring is possible, and the use of fine via structures (microvias) enables smaller, higher performance boards.
It is widely used in smartphones and high-performance modules.
type 04
IVH/SVH
This is a multi-layer printed circuit board that supports high-density mounting and is characterized by the use of laser vias for interlayer connections.
IVH (Interstitial Via Hole) connects between intermediate layers, while SVH (Stacked Via Hole) connects multiple layers stacked together.
It allows for fine wiring and is widely used in smartphones and other high-performance devices.
type 05
Rigid Flex
This is a composite board that integrates a rigid board and a flexible board.
It allows for high-density mounting and three-dimensional wiring, and is excellent for space saving and weight reduction.
They are primarily used in mobile devices, medical equipment, and automotive equipment, and are suitable for applications requiring high reliability.
type 06
FPC (flexible printed circuit board)
This is a printed circuit board with wiring formed on a flexible insulating film, which allows it to be bent or folded.
Lightweight and thin, it is suitable for space-saving designs and is ideal for wiring in moving parts and narrow spaces.
It is used in a wide range of fields, including smartphones, cameras, and medical equipment.
type 07
Through-hole board (2 to 48 layers)
This is a multilayer printed circuit board that is electrically connected from the outer layer to the inner layer with via holes (through holes).
Its structure penetrates all layers, making it highly reliable and relatively inexpensive to manufacture.
It is used in a wide range of applications, including general electronic devices and industrial equipment.
type 08
High density wiring board
Printed circuit boards that can arrange fine wiring and vias (holes) at high density enable space saving and high performance.
Laser vias and build-up structures are used to support multi-layering and miniaturization.
It is widely used in smartphones, tablets, wearable devices, etc.
type 09
Any Layer
This is a high-density wiring board that can directly connect any layers with vias.
Unlike conventional build-up boards, there are no connection restrictions for each layer, allowing for greater design freedom and enabling high performance and miniaturization.
It is mainly used in high-speed, high-performance electronic devices such as smartphones and communication devices.
type 10
Large current/heat sink
The printed circuit board is specially designed to carry high currents and uses materials with excellent thermal conductivity to dissipate heat efficiently.
This reduces the temperature rise in areas where current is concentrated, improving the reliability of the board.
It is mainly used in power electronics and power supplies.
type 11
Aluminum
This printed circuit board uses aluminum as the base material, which has excellent thermal conductivity and excellent heat management.
They are particularly widely used in high-power LEDs and power electronics, where they efficiently dissipate heat, preventing overheating and extending the life of devices.
