FR4 Green Oil Solder Masked PCB Board Through Hole Design OEM Service
FR4 solder-masked 6-layer board PCB
A 6-layer FR4 solder mask PCB is a multilayer printed circuit board (PCB) based on an FR4 substrate and including its solder mask layer. Designed for complex electronic designs, this PCB consists of six layers, typically consisting of an outer copper foil layer, an inner signal layer, an inner copper foil layer, and a substrate layer. FR4 acts as an insulating core material, providing mechanical strength and electrical performance. A solder mask (usually green) covers the copper layer to prevent short circuits and oxidation, leaving only the solder pads for soldering.
Advantages of Multilayer PCB:
| Feature | Description |
| Structure | Typically consists of 6 layers: outer copper layers, inner signal/power layers, and FR4 dielectric layers, with a solder mask on top and bottom. |
| Solder Mask | The solder mask (usually green) covers the copper traces, protecting against oxidation, short circuits, and environmental damage. |
| High Density | Supports complex circuitry and dense component layouts due to multiple layers. |
| Signal Integrity | Offers good signal integrity and reduced electromagnetic interference (EMI) thanks to inner layer shielding and controlled impedance design. |
| Mechanical Strength | FR4 material provides high mechanical strength and dimensional stability. |
| Application | Commonly used in complex electronic devices such as computers, industrial controls, and communication equipment. |
| Cost & Complexity | Higher manufacturing cost and design complexity compared to simpler boards. |

FAQ:
1.Q:What kind of circuit board is this product?
A:A multilayer PCB is an integrated board made of stacked copper circuit layers separated by insulating materials and connected via vias for compact, complex circuits.
2.Q:How many layers can your circuit boards provide?
A:We typically provide 1-30 layer boards.Commonly available custom layer counts are 2, 4, 6, 8, and 10 layers.and in special cases, we can stack more layers.
3. Q:Do your circuit boards support customization?
A:Yes, we support customized designs. You can send us your Gerber files and BOM list, and we will provide you with an accurate quote based on the information and market conditions.
4. Q:What do Gerber files typically contain?
A:Normally Gerber files Include:PCB Types,Product thickness, Ink color, Surface treatment process and If SMT processing is required, component BOM and tag drawing are also required.
5. Q:What is your minimum order quantity for PCB boards?
A:Our minimum order quantity is 1 piece(5 square meters),the larger the quantity, the bigger the discount.
6. Q:Do you have relevant certification certificates to support this?
A:We hold numerous important certifications, including ISO, UL, CE, and RoHS. All products undergo rigorous quality testing.
7. Q:What payment method do you usually use?
A:For small orders, samples, or urgent payments, we accept Western Union. For large orders, we recommend T/T, which ensures the safety of both parties.
