Custom Electronic Circuit Board FR4 94v0 ROHS PCB Supplier
It is a PCB base material that comes as a fiberglass laminate sheet reinforced with epoxy resin. It is a common laminate substrate in printed circuit boards because of its sturdy nature and flame-retardant properties. As such, it is vital to provide circuit boards with the required insulation. FR4 boards have largely replaced the G-10 boards as much as the G-10 boards still find applications where thermal destruction proves key.
An FR4 material complies with the UL94V-0 standards when it comes to plastic in-flammability. The standards ensure that it cannot propagate fire and extinguishes it immediately after the material starts to burn.
Fr4 materials use bromine. The halogen chemical element is resistant to fire and thus valuable in providing the fire-retardant properties to FR-4.
It also cannot absorb water, maintains the high mechanical strength, besides the incredible insulating capacity, especially in humid or dry environments.
FR4 material also has a high glass transition temperature of between 115 and 200 degrees Celsius. However, this depends on the methods of manufacturing and the resin types used. In most instances, the FR4 PCB will contain an FR4 sandwiched between two copper layer laminates.
The FR4 material can come as the standard FR4, the high TG FR-4, the high CTI FR-4, and FR4 without any laminated copper. A standard FR4 has a heat resistance of 140-a50 degrees Celsius, while a high TG FR4 possesses a glass transition value of 180 degrees Celsius. On the other hand, the high CTI FR4’s index exceeds 600V, and the FR4 devoid of laminated copper proves ideal for board support and insulating plates.
The thickness of the FR4 material plays a crucial role in diverse PCB applications. Therefore, picking the correct thickness should take into account the following.
| Item | Capability |
| Base Material | FR-4 / High TG FR-4 |
| Layers | 1-22 |
| Finised inner/outer copper thickness | 1-6OZ |
| Finished board thickness | 0.2-7.0mm |

| Controlled Impedance | +/-5% |
| Plugging vias capability | 0.2-0.8mm |
| Outline profile | Rout/ V-cut/ Bridge/ Stamp hole |
| Surface treatment | HASL, HASL lead free, Immersion Gold, Immersion Tin, HOSP… |
The most basic printed circuit boards are the ones that contain copper tracks or interconnects just on one of its surfaces. These sorts of boards are known as 1-layer printed circuit boards or 1-layer PCBs. A single-layer printed circuit board has an inner layer and an outer layer.
In the below illustration, you can see the stack-up of a single-layered printed circuit board.
PCB substrate can be FR4, metal, or ceramic. FR4 is mostly used and is a reinforced epoxy laminate material. It is the base substrate of the printed circuit boards. It is an extremely durable material and there are different thickness types. Some PCBs, especially the cheaper ones, are made from other materials and they lack FR4 durability.
The copper layer is a thin foil of copper. It is laminated to the board with adhesive and heat. It is commonly applied on both sides on a double-sided printed circuit board. A two-layered or double-sided board means that there are two copper layers in the structure. You can find PCBs with only one or more than 16 copper layers!
Have you ever wondered why the PCB boards are green? Because of the solder mask layer. This is the top layer above the copper foil and it gives the printed boards their green color. The main purpose of this layer is to insulate the copper traces from accidentally contacting any solder or metal. The common color is green, but have in mind that the solder mask could be manufactured in nearly all possible colors.
On top of the solder mask, a white silkscreen layer is applied. It is used to insert any numbers, symbols, or letters as instruction like a guideline for people to better understand the board. Again, any color can be used and there are PCBs with yellow, red, or even black silkscreen.
