What is book binder flex pcb?

Multilayer flex PCB bookbinding

Circuit bookbinding is one of the best practices employed by Hemeixin engineers for creating stacked PCBs.
For flex PCBs, we offered a 12 layer flex PCB board with bookbinding.

An additional small length is added to the circuit, making it move in an outward direction from the bend radius.
There are copper traces placed at right angles to the bend. This helps restrict the circuit bend in one direction.

The length to be added depends on total number of layers in the PCB,
as well as the tightness of the bend.

The advantage of circuit bookbinding is that it removes a great amount of tension from the various circuit layers during the bending process.
The method also helps prevent buckling of the circuits at the exact bend radius.

The bookbinded PCBs can easily meet the tight tolerance requirements in comparison to bonded PCBs.
This is why this 12 layer flex PCB is a perfect choice for applications where stricter tolerances are required.

Its polyamide construction delivers immense strength and flexibility. This flexi PCB can easily perform 180° bends.
Also, the construction helps prevent buckling of inner layers, which often occurs in a long term use.

This flexibility also helps reduce stress on the internal components.
This 12 layer flex PCB board has better shelf life than a 12 layer bonded circuit board.

The immersion gold plating offers low contact resistance, good wetting, as well as excellent shelf life.
We can provide the 12 layer flex PCB board with book binding in width 4/4 mil,

with minimum finish thickness 0.15 mm flex and maximum 1.6 mm.

the role of book binder flex pcb

The role of a book binder flex PCB is to provide a flexible and durable circuit board that can be integrated into the spine of a book.
The book binder flex PCB can be used to add electronic features to a book, such as LED lights, sensors, or other interactive elements.

The flexibility of the PCB allows the book to be opened and closed without damaging the circuitry,
making it an ideal solution for books that require electronic components.

In addition to book binding applications, book binder flex PCBs can also be used in other applications where flexibility and durability are important.
For example, they can be used in wearable technology, medical devices, and other electronic products where space is limited and flexibility is required.

The role of a book binder flex PCB is to provide a reliable and flexible circuit board solution that can be customized to meet the specific needs of the application.
