Before your engineers design the PCB, you can communicate with us knowing that we are going to understand what it is you need, and that we can offer the best way to get them there. The follows basic three steps to design your circuit board .

Step 1 - Gather the necessary informations:

Request these guides before starting your design process:

• Learn PCB General Design Tips, dimensional tolerances, conductor design data, and artwork layout, etc.
• Get a brief glance at our production capability to get the design assistance and specifications for flex circuits.
• Learn the information about material of PCB, Ceramic PCB substrate, and choose a suitable types. For example, if you want to have designed impendance control, you need to know material Dielectric constant of material (for FR4, the popular value is 3.8~4.8) . You can see our excel formal to calculate impedance, or use professional tool such as Polar Si6000b, Si8000m.

Step 2 - Choose a suitalbe PCB types and follow up standard design flow

If you'd like to use high density, need dozens of layers, then use multi-layer FR4 PCB; if want good heat elimination, then metal core PCB will be a good idea; if you need RF board, then consider using Rogers or Telfon; if you are going to solder ceramic Cap, ICs, Resistors on PCB and need a high precision on dimension, low expansion coefficient, high thermal conductivity and high-temperature resistance, excellent erosion and wear resistance, then Ceramic PCB will be best choice.

you want to design Metal Core PCB, you should know T-Guard for performance by Best PCB, they have excellent design guide for MCPCB, from single layer to double layers, through Multi-layers MCPCB. You can also download it here:

• T-guide for Performance
• T-guide for Manufacturability
• Single Layer IMpcb Fabrication Guideline
• Multi Layer IMpcb Fabrication Guideline

For Ceramic PCB design, please see following design guide.

• DCB Ceramic PCB Design Guide
• Thick Film Ceramic PCB Design Guide

Step 3 - Send us your request for quote:

Our policy is to identify and correct potential problems with flexible circuitry at the quoting stage, not after we accept your order. We can use any information you have and create a fully functional board for you. We can accept various file formats with our state-of-the-art CAM software. Using our experience and knowledge of flex printed circuits, We can go through your supplied files and spot any potential design problems before they get to photo production. We can edit your files to make sure they are per DFM (Design for Manufacturability). Best FPC can also use a supplied schematic and design you a custom FPC from that!

To evaluate your circuit board and quote a firm price we need:

• A circuit drawing with outline dimensions, cutouts, and dimensional tolerances.
• A Drill Chart of hole locations, sizes, and access hole diameters with tolerances.
• A material cross section (circuit stackup) specifying thickness of each layer.
• A photocopy of artwork or CAD data (if available) showing conductor layout and widths, with all applicable tolerances.
• All testing, inspection, and packaging requirements.
• A "Readme" file in txt or PDF.
