PCB Sampling

Why Need Sampling:

PCB Sampling refers to the process of making a small number of circuit board samples in order to verify and test the circuit board design before mass production. This process is crucial for ensuring that the circuit board design meets the expected functional and performance standards. Sampling can help identify design issues for modification before mass production, saving costs and time, and improving the quality of the final product. We provide PCB sampling service to all customers before mass production and orders.

PCB Sampling Process:

  • PCB design: This is the starting point of the sampling process, which requires the use of professional circuit design software to complete the circuit diagram and layout design.

  • Submit design documents: Submit the designed PCB files (such as Gerber files) to us. These files shall contain all the necessary information for manufacturing circuit boards, including the layout of each layer, drilling, screen printing, and solder pads.

  • Manufacturing prototype: We will manufacture circuit boards based on the submitted design documents. This process includes multiple steps, such as material cutting, acid washing, electroplating, copper coating, drilling, imaging, etching, pad gold plating, screen printing, surface treatment, etc.

  • Testing and Verification: After receiving the prototype, the designer needs to test it to verify whether the functionality and performance of the circuit board meet the design requirements. Testing can include electrical testing, functional testing, and environmental testing.

  • Modification and optimization: Based on the results of sample testing, it may be necessary to make some modifications and optimizations to the circuit board design to improve performance or solve the discovered problems. Then, it may be necessary to make another sample to verify these modifications.
