Double Sided Sunken Gold Process BT PCB Printed Circuit Board For Electronics Device

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.
