1. What is the mean by “Premium”?

The PCB Service can meet >95% customer’s requirements, but for some customers, especially makers who have experience in hardware developing and projects that need many special requirements. They need more reliable& advanced PCB service, such as multiple layers more than 4, FPC,  Immersion silver(AG) finished,  Flash gold/gold finger,  Epoxy Via Plug,  BGA or pad less than 0.3mm,  width of wire less than 4 mils,  drill holes less than 0.3mm,  insulated Metal Substrate,  HDI,  High frequency ROGERs, Castellation Plating, etc.. That’s why we Elecrow provides this “Premium PCB Service”.


2. What’s the main upgrading compared to the common PCB services?

This “Premium PCB” service is based on “One-by-One Quotation”, so we would be able to meet your personal requirements. Compared to the common PCB service, the main upgrading is as following.

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.

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.
Please refer to the below details and specifications:
Flex/ Rigid-Flex/ Multilayer Flex PCB
Elecrow is devoted to provide affordable flex PCB. If you are looking for a flexible PCB or Rigid-flex PCB supplier, our engineers are here to help you solve your technician questions and meet your requirement. We can assist you to prototype sample or small batch soft circuit boards.  Our Flex PCB group is able to provide you with flexible PCB as well as Rigid-flex PCB with a variety of technologies, from single-sided flex PCB to complex multilayer flexible PCB and Rigid- flex PCB with Impedance Control PCB.

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.
