FPC

Overview:

With the trend of lighter, thinner and smaller product development, FPC is becoming a well-developed alternative of the PCB in some product applications.


Ideal Jacobs is specialized in design support, quality and most importantly the cost control through years of support to elite customers. We further insert FPC into the membrane switches to help our customers enhance human-machine interfaces, to simply assembly with counterparts and to further improve the whole space of products especially for main PCB. 


Flexible Printed Circuit largely improves the user experience and helps customer with more possibilities in product design by its compact size and light weight. It stretches freely in a three-dimensional space. Rigid-Flex PCB, on the other hand, can be an excellent support body of electronic components while being flexible.

Rubber keypads

Rubber keypads are manufactured from silicone rubber properties that are typically processed from either injection or compression molding. They have exceptional resistance to extreme temperatures and environmental factors, making them an ideal choice for products exposed to harsh environmental conditions, moisture, chemicals, etc
 

Ideal Jacobs offer a wide range of design possibilities due to the many sizes, shapes, and colors that it can be molded into. Our rubber switches be easily integrated into both flex circuitry and PCB-based membrane switch assemblies allowing for both reduction in cost and assembly time.

1)     Single Layer of FPC

It has a layer of chemically etched conductive pattern, and the conductive pattern layer on the surface of the flexible insulating substrate is a rolled copper foil.


2)     Double-sided FPC

The double-sided FPC has a conductive pattern made by etching on both sides of the insulating base film, which increases the wiring density per unit area.


3)     Multilayer FPC

Multi-layer FPC is to laminate 3 or more layers of single-sided or double-sided flexible circuits together, and form metallized holes by drilling and electroplating to form conductive paths between different layers.


4)    Rigid-Flex  PCB

it includes two or more conductive layers that comprise either flexible or rigid insulation material between each one. Both rigid and flexible areas that make them ideally suited for a wide range of applications.
