The production process of aluminum substrate mainly includes the following key steps:

Material preparation:

Choose high-quality aluminum substrate materials to ensure they meet production requirements.
Due to the high cost of aluminum substrate materials, special attention should be paid to material protection and rational utilization to avoid waste.

Cutting and cutting:

According to the product design requirements, accurately cut the aluminum substrate to the required size.
Handle with care during operation to avoid scratches on the surface of the board and aluminum substrate.

Drilling and milling:

Drill the required through holes, blind holes, etc. on the aluminum substrate to meet the requirements of circuit layout and component installation.
Perform edge milling to ensure that the edges of the aluminum substrate are flat and smooth.

Line production:

By using photolithography, electroplating and other processes, the required circuit patterns are fabricated on an aluminum substrate.
During this process, operators should avoid direct contact with the effective area of the aluminum substrate by hand to prevent contamination or damage.

Solder mask and characters:

Apply solder mask ink on the circuit pattern to protect the circuit from external environmental influences.
Print character markings for subsequent assembly and maintenance.

Surface treatment:

According to the needs, aluminum substrates are subjected to surface treatments such as tin spraying and OSP to improve their welding performance and reliability.
During tin spraying and subsequent processes, only hold the edge of the board when holding it, and it is strictly prohibited to touch the inside of the board directly with fingers.

Testing and Inspection:

Conduct comprehensive electrical performance testing and quality inspection on aluminum substrates to ensure they meet design requirements.
Each district and process should attach great importance to quality control to ensure the smooth production of aluminum substrates in each process.

Packaging and Shipping:
Package qualified aluminum substrates to prevent damage during transportation and storage.
Prepare relevant documents and materials according to customer requirements for shipment.
Throughout the entire production process, special attention should be paid to the standardization of operations to ensure the quality and performance of aluminum substrates.
