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.
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:
We have two Circuit Configurations
1. Single-SidedHere 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.
