How to distinguish FR4 circuit board from ordinary board or high frequency board
Ordinary board fiber paper
High frequency plate alkali free glass cloth
High frequency plate is usually pressed with FR4 glass fiberboard, and the whole sheet of epoxy resin glass cloth is pressed, the color of the whole plate is more uniform, bright.Density than the low-frequency plate is larger, is the weight of the focus.
Low-frequency board a lot of pressure in the lower part of the material, such as: paper base board, composite substrate, epoxy board (also called 3240 epoxy board, phenolic board), FR - 4 glass fiber board (ingredient) production, the paper substrate and composite substrate, the overall density is lower, the same color on the back, but careful watching there is basically no easy to see substrate glass fiber cloth grain.The difference between epoxy board and FR4 glass fiber composite board is that the back substrate has different shades of color. When the epoxy board is at the broken part, it is easy to see white powder and the color is beige when you scrape it with your hand or other tools.The FR4 panel is easier to see because it is pressed with the FR4 fiberglass fabric scrap, and the whole panel is covered with large stripes on the back.

Q: No PCB file/Gbr file, only have the PCB sample,can you produce it for me?
A: Yes, we could help you to clone the PCB. Just send the sample PCB to us, we could clone the PCB design and work out it.
Q: What is Chuante lead time?
1-2 Layers: 5 to 7working days
4-8 Layers: 12 working days
1-2 Layers:7 to 15 working days
4-8 Layers:10 to 18 working days
The leadtime is depends on your final confirmed quantity.
