Multilayer PCB

The Multilayer PCB can be used on electric services, such as cell phone transmission, cell phone repeaters, computer motherboard, data storage and GPS technology. In order to reduce signal loss, use a multi-layer shield signal, such as the base station, the communication class. Besides, it also can be used on medical equipment: X-ray equipment, heart monitors and so on.

Please refer to the below details and specifications:

Aluminum PCB(MC PCB, AL substrate)

Elecrow is devoted to provide Aluminum substrate, if you are looking for an Aluminum substrate, our engineer can meet your requirement. Aluminum substrate is a kind of copper-clad circuit board based on metal substrate, with good thermal conductivity. A thin layer of thermally conductive but electrically insulating dielectric is laminated between a metal base and a copper foil. The copper foil is etched into the desired circuit pattern and the metal base draws heat away from this circuit through the thin dielectric.

It can be used on the following areas:

1. Audio equipment: input, output amplifier, balanced amplifier, audio amplifier, preamplifier, power amplifier, etc.
2. Power equipment, switching regulator, DC/AC converter, SW regulator, etc.
3. Communication electronic equipment: high frequency increaser, filtering appliances, transmitting circuit.
4. Office automation equipment, motor drives, etc.
5. Automobile electronic regulator, ignition, power controller, etc.
6. Computer: CPU, a diskette drive, power supply units, etc.

Power module, inverter, solid relay, rectifier bridge, etc.

We have two Circuit Configurations

1. Single-Sided

The single-sided aluminum pcb can be used with surface mount and chip & wire components.

2. Double-Sided
This structure need more technology and experience on laminating of two layers together with metal core.

Here are the general benefits of our Flex PCB service

1. Excellent Flexibility: Stable and repeating flexibility is helpful for 3-D electronic  products assembly.

2. Lower Toughness: Lower toughness is benefit for standing more thermal stress and reducing  the joint cracking risk.

3. Thin dielectric: Thin dielectric could have better flexibility and better heat transfer,  those will be benefit for structure design and thermal management.

4. Great high temperature performance: PI material could be operated under high temperature  environment then can fit for high temperature applications.

5. Good manufacturability: Some flexible material can use laser or chemical etch create pads  or window then could be used in double access applications.

6. Multi-plane connection and size shrinking: Flexible boards could be bended and binding  with rigid-flex technology then can reduce connector and terminator using that can reduce weight.

7. High space utilization: Flexible boards can replace many connecting parts and join multi  plane boards then by these strength can saving space and make design easier.

Here are the basic structure of Flex PCB

Single Side Double Access	Double Side	Single side plus Single Side	Multi-layers

Here are some regular FPC in the application

FPC for Antenna	FPC for Notebook Camera	FPC for Winding Displacement
FPC for Button	FPC for Monitor	FPC for LED Module
