Double-sided sunken gold process
Double-sided sunken gold process, also known as double-sided printed circuit board, is a printed circuit board (PCB) with two-sided circuit
connections. In this kind of PCB, the electronic components and
circuit layout can be arranged on both sides of the PCB
respectively, and the electrical connection of the circuits on both
sides is achieved through vias (Vias). This structure greatly
increases the functional density of the circuit board, allowing it
to implement more circuit connections in a relatively small area.
Advantages of Double-sided PCB:
- Increase the wiring space
- Improve the circuit functional density
- The cost is relatively low
- Good electrical performance
- Adapt to high integration requirements
Manufacturing process:
- Design and layout:Firstly, the PCB design is carried out through circuit design
software, with wiring and component placement on both sides, and
the position type of vias are planned at the same time.
- Drilling and electroplating: Drilling is carried out according to the design requirements, and
electroplating is performed after drilling to form a via the
circuits on both sides.
- Etching: Remove the excess copper foil to form the desired circuit pattern.
- Assembly and welding: After the components are installed, welding treatment is carried
out, which can be done using surface-mount technology (SMT) or
through technology (THT).
FAQ Related to Double-sided BT PCBs
1.Q:What kind of circuit board is this product?
A:The name of this product is BT PCB.BT PCB refers to printed
circuit boards fabricated with BT resin (Bismaleimide-Triazine
resin) as the core substrate material
2.Q:How many layers can your circuit boards provide?
A:We typically provide 2-30 layer boards, 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.
