What are printed wiring boards?
Printed wiring boards (PWBs) are an essential component in modern electronics products. Here, we explain what printed PWBs are, their role, and what products they are used in.

The birth of PWBs
Prior to the invention of PWBs,
electronic products were large
due to inefficient wiring.
In the electronics products of those days,
vacuum tubes were used in place of
semiconductors, and vacuum tube sockets
and other parts had to be soldered by hand.
For that reason, component attachment was
time-consuming, and there were many wiring mistakes,
leading to short product life.
To solve these problems,
PWBs with circuits formed directly
on them were invented.
With the invention of PWBs,
electronics product manufacturing became efficient,
quality became stable, and mass production became possible.

PWBs that connect the future of electronics
In modern times, our lives abound with myriad products like smartphones, IoT home appliances, industrial devices, IT infrastructure, and so on. Behind that progress is the PWB that made high functionality and high integration possible.
High integration means putting more components into a limited space. The PWB is the part that connects all the components in an electronic device. If semiconductors are the "brains" of electronics products, we might say that PWBs are the "bones and blood vessels".
That's why the evolution of the PWB, which connects the many semiconductors and other components, is so necessary. Currently, it is said that the number of components that can be mounted in an integrated circuit of a given size doubles every two years. That's how fast the pace of integration is.
The importance of semiconductor development is well-known, but it is because advances were also made in PWB technology that electronics products have continued to develop. PWBs are an important component in the creation of new products.

Here, there and everywhere.
Where PWBs operate -
PWBs are used in everyday things like lights, cameras, home appliances and smartphones, to industrial robots, medical devices, and rocket ships.
Satellites
Lightweight printed wiring boards that are highly reliable and heat resistant are used because they can withstand the extreme operating environment and improve fuel efficiency.
Game Consoles
Printed wiring boards in game consoles connect the components and supply power to support performance and features such as smooth motion, data management, and beautiful graphics.
Televisions
In televisions, printed wiring boards are used to connect the many components in video and audio signal processing and power supply circuits.
Smartphones
Thin, small printed wiring boards are used in large numbers in compact, feature-rich, high component-count smartphones.
Trains
Printed wiring boards are used in operation control, communications systems, information display systems and other functions necessary for train safety, comfort and efficiency.
Rockets
Lightweight printed wiring boards that are highly reliable and heat resistant are used because they can withstand the extreme operating environment and improve fuel efficiency.
LED Lighting
Printed wiring boards with excellent heat dissipation and durability are widely used to support LED performance and reliability.
Automobiles and Self-driving Automobiles
Printed wiring boards are used in many automotive applications to enhance safety and comfort. As vehicle electrification and self-driving progress, printed wiring boards are becoming more important.
Supercomputers
and Servers
Supercomputers and servers must deliver high functionality and high reliability. For that reason, high performance printed wiring boards like high-layer count printed wiring boards and printed wiring boards designed for high-speed communications are used.
Industrial Devices and Inspection Equipment
Industrial devices and inspection equipment are indispensable in factory automation, efficiency improvements, and ensuring product quality. High reliability, high precision and high environmental durability printed wiring boards are used in these applications.
Home Appliances (Microwave ovens, robot vacuum cleaners, etc.)
Printed wiring boards designed to meet the required functionality are used in the home appliances that make our everyday lives convenient. The high manufacturing volumes of home appliances make the cost efficiency provided by printed wiring boards critical.
Phones and PBX
Printed wiring boards are used to convey the signals in the phones indispensable to our everyday lives.
Personal Computers
In the personal computers indispensable to businesses and schools, printed wiring boards are used to improve performance and reliability and make them more compact.
Automatic Doors, Automatic Locks, Security Cameras, Smoke Detectors
Printed wiring boards used in electronic security devices help keep us safe.
Medical Devices
Medical devices used to protect human health and safety are manufactured under stringent regulations and quality control, and require printed wiring boards of high reliability and high environmental durability.

Lincstech PWBs answer customer needs
-
-
Through the manufacture of PWBs, Lincstech has been supporting our customers for over 60 years in bringing their high functionality products to life. Our broad lineup was created in order to address our customers' needs.
Take multi wiring boards (MWB), for example.
MWB's key characteristic is that it allows wires to cross in a 3-dimensional structure, allowing high wiring density per layer.To answer the customers' needs to pack more wires into a limited space and thickness, Lincstech created our own original MWB technology that allows wiring densities not normally achievable.
Each of Lincstech's PWB exists because our customers told us: "This is the kind of PWB we want." At Lincstech, our style is to support our customers' development without placing limitations on the form of their ideas.
Co-Creating the future of
electronics with our customersOur Purpose
PWBs have developed right along with electronics products.
The smartphones that fit in the palm of your hand have more computing power than
the early computers which were several times the size of a human.
From everyday life to aerospace, it is expected that the indispensable
PWBs will need to have even higher functionality and integration.
Through our PWBs, Lincstech will support 5G/6G communications,
the practical implementation of AI, self-driving and other global technologies of the future.
