PCB manufacturing (Printed Circuit Board Manufacturing) refers to the process of designing and producing printed circuit boards, which are one of the basic components of electronic devices. PCB manufacturing includes multiple steps, from raw material selection to final testing, and each step requires a high degree of precision and quality control.
When selecting a PCB manufacturing supplier, you should focus on key attributes such as quality and certification, manufacturing capabilities, cost-effectiveness, customer service, experience and reputation, customization capabilities, environmental and social responsibility, and geographical location.
The types of surface finishes in PCB manufacturing include Hot Air Solder Leveling (HASL), which covers with tin-lead alloy or lead-free alloy, commonly used for general applications; Electroless Nickel Immersion Gold (ENIG), which plates a layer of nickel and gold, providing a smooth and solderable surface, suitable for high-end applications; Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG), which has multiple layers (nickel, palladium, gold) offering excellent soldering and electrical performance; Immersion Tin, which covers a layer of tin ensuring good solderability and electrical connections; Immersion Silver, which covers a layer of silver providing excellent solderability and conductivity; and Organic Solderability Preservative (OSP), which uses organic compounds to protect copper, suitable for short-term storage and low-cost applications.
To obtain PCB manufacturing services, you need to prepare the following detailed files and information:
Gerber Files: These contain PCB layer information such as copper layers, solder mask layers, and silk screen layers, used for manufacturing and inspecting the specific layout and design of the PCB.
NC Drill File: Includes information on all hole positions and sizes required to be drilled on the PCB, ensuring accurate placement of component mounting holes and vias.
BOM (Bill of Materials): This lists all components used on the PCB, including details like component names, part numbers, quantities, and specifications, aiding manufacturers in preparing and procuring necessary parts and materials.
PCB Layout File: These files display the specific layout and positions of all components on the PCB, including pin locations and connection details, crucial for manufacturing.
Mechanical Drawing: Provides detailed descriptions of the PCB's dimensions, board thickness, hole positions, and edge cuts, ensuring the PCB shape and size align with design requirements.
Assembly Drawing: These drawings indicate the placement, orientation, and correct assembly method for each component on the PCB, ensuring accurate assembly processes.
Special Requirement Specifications: If there are specific manufacturing requirements or needs, such as particular surface finish requirements (e.g., ENIG or HASL), special material requirements, or testing requirements, detailed specifications are necessary to ensure manufacturers can comply with your requests.
Test Specifications: Clearly outlines various testing requirements and standards, including electrical tests, functional tests, or reliability tests, ensuring the final PCB meets expected performance and quality standards.
Preparing comprehensive files and information helps manufacturers accurately understand and execute your PCB manufacturing requirements, ensuring the production of high-quality PCB products as expected.
If the PCB product does not meet your requirements, you can take the following steps:
- Inspect and Confirm the Issue:
- Internal Inspection: Carefully examine the received PCB and document all areas that do not meet the requirements, such as appearance defects, electrical issues, or functional failures.
- Review Documentation: Recheck the design files and specifications you provided to the manufacturer to confirm whether the issue originated from the design or manufacturing process.
- Contact the Manufacturer:
- Detailed Problem Description: Provide the manufacturer with a detailed description, including photos, videos, and test data, clearly explaining the non-conforming aspects.
- Provide Feedback and Evidence: Attach relevant documents and evidence, such as inspection reports and design files, to help the manufacturer understand the specific issue.
- Rework or Replacement:
- Rework or Repair: If the issue can be fixed, agree with the manufacturer on rework or repair, and confirm the time and cost involved.
- Remanufacture: If the issue is severe and cannot be fixed, request the manufacturer to remanufacture new products that meet the requirements.
- Quality Improvement:
- Root Cause Analysis: Work with the manufacturer to analyze the root cause of the issue to prevent similar problems in the future.
- Process Improvement: Improve the design and manufacturing processes to ensure future products meet the requirements.
These steps can help you effectively address non-conforming PCB products, ensuring your project proceeds smoothly and meets the expected quality standards.

- Bed of Nails Test: Used for high-volume production, where fixed probes test the circuit's connectivity and electrical performance.
X-Ray Inspection:
- 2D X-Ray Inspection: Used to inspect the internal structure of the PCB, especially for multilayer boards or complex packages like BGAs (Ball Grid Arrays).
- 3D X-Ray Inspection: Provides a detailed three-dimensional view for further analysis of solder joints and internal structures.
Functional Testing:
- Simulates real working conditions to test the PCB's functionality and performance, ensuring its reliability in actual applications.
Solder Quality Inspection:
- Visual Inspection: Manual inspection of solder joints and component placement quality.
- Infrared Inspection: Uses thermal imaging to detect heat generated during soldering, evaluating solder quality.
Environmental Testing:
- Thermal Cycling Test: Exposes the PCB to extreme temperature cycles to test its reliability under high and low-temperature conditions.
- Humidity Test: Tests the PCB's performance in high humidity environments.
Impedance Testing:
- Ensures that specific signal lines have controlled impedance within the design range, especially important in high-frequency applications.
