PCB Fabrication Services FAQ
What is PCB fabrication?
PCB (Printed Circuit Board) fabrication is the process of creating printed circuit boards, which are used to mechanically support and electrically connect electronic components. The process involves several stages including design, material selection, drilling, plating, and final assembly.
What materials are commonly used in PCB fabrication?
The most commonly used materials in PCB fabrication include:
FR-4: A glass-reinforced epoxy laminate that is the industry standard for most PCB applications.
CEM-1 and CEM-3: Composite materials used for simpler electronics.
Polyimide: Used for flexible PCBs due to its excellent thermal stability.
Metal Core: Used for high-power applications that require better heat dissipation.
How long does it take to fabricate a PCB?
The time required for PCB fabrication can vary based on complexity and volume. Typically, standard PCBs can be fabricated within 5-7 business days. Expedited services are available for faster turnaround times, sometimes as quick as 24 hours.
What is the difference between single-sided, double-sided, and multilayer PCBs?
Single-sided PCBs have components on one side and are simpler and cheaper to produce.
Double-sided PCBs have components on both sides, allowing for more complex circuits.
Multilayer PCBs consist of multiple layers of substrate material, offering high density and complexity for advanced applications.
Can you assist with PCB design as well?
Yes, we offer comprehensive PCB design services. Our team of experienced engineers can help you with schematic capture, layout design, and optimization for manufacturability to ensure your PCB meets all specifications and performs reliably.
What file formats do you accept for PCB fabrication?
We accept a variety of file formats including Gerber files, ODB++, and IPC-2581. It’s important to ensure your files are complete and correctly formatted to avoid any delays in the fabrication process.
What quality control measures are in place for PCB fabrication?
We adhere to stringent quality control measures throughout the fabrication process, including:
Automated Optical Inspection (AOI) to check for defects.
Electrical Testing to ensure circuit continuity.
Material Inspection to verify the quality of raw materials.
Final Inspection to ensure the finished product meets our high standards and your specifications.
Do you offer prototyping services?
Yes, we offer PCB prototyping services to help you test and refine your designs before full-scale production. This allows you to identify and correct any issues early in the development process.
What is the minimum order quantity (MOQ) for PCB fabrication?
We have flexible minimum order quantities to accommodate both small and large production runs. For specific details regarding MOQ, please contact our sales team.
How do I place an order for PCB fabrication?
To place an order, you can contact our sales team directly through our website or email. You will need to provide your design files, specifications, and any special requirements. Our team will guide you through the process and provide a detailed quote.
