Designing your PCB
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 printed 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, 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 Laird Technolgies, they have excellent design guide for MCPCB, from single layer to double layers, through Multi-layers MCPCB. You can also download it here:
Step 3 - Send us your request for quote:
Best FPC's 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 flexible circuit and quote a firm price we need:
- A circuit drawing with outline dimensions, cutouts, and dimensional tolerances.
- A chart of hole locations, sizes, and access hole diameters with tolerances.
- A material cross section (circuit stackup) specifying insulation thickness, adhesive, conductor thickness, and stiffener type and thickness.
- A photocopy of artwork or CAD data (if available) showing conductor layout and widths, with all applicable tolerances.
- All testing, inspection, and packaging requirements.
