Given the precision required for high-frequency PCB design, we have found that all stages of manufacturing high-frequency PCBs must be carried out with unparalleled caution and precision, as they are naturally used as circuit boards for many devices and applications with sensitive and hazardous tasks, such as medical and military equipment. Therefore, the error rate in the manufacturing process of high-frequency PCB boards must be zero. When starting the manufacturing process of high-frequency PCB boards, please consider the following points.
1. PCB design
The high-frequency PCB manufacturing process begins to ensure the integrity and reliability of the design scheme of the high-frequency PCB board you previously designed. You should conduct all tests on the design to ensure its suitability for manufacturing.
2. Circuit positioning and etching
The design drawings are printed using a dedicated PCB printer. It is printed on the inner copper layer, which is connected to the substrate representing the PCB structure of the board. After completing the printing and engraving process on copper, the inner and outer layers will align perfectly and ensure that they are arranged correctly.
3. Electroplating
Install the inner and outer copper layers separately after plating, and collect the inner and outer layers.
4. Drilling
After the layering process is completed, the drilling process begins, using drilling equipment such as X-ray machines to identify holes and then proceed with drilling.
5. Circuit board cleaning
After the etching process is completed, clean the circuit board and remove excess copper. Afterwards, the circuit board can be coated with chemicals specifically designed for PCB painting, which help to merge and bond the layers together.
6. Solder mask
Ensure again that the circuit board is completely clean before placing the solder mask layer on it. In order to protect the solder mask layer, copper, and all layers of the high-frequency PCB, screen screening and precision machining are required
7. Testing and Inspection
The high-frequency PCB board is now ready for testing to ensure the performance of the circuit board, such as insulation testing, electrical performance of the circuit board, and other tests required to ensure smooth operation of the circuit board.
However, if a company cannot guarantee that all these considerations are met with high capability and efficiency, accurately and reliably executing all these stages, the likelihood of errors occurring during the manufacturing process will be high. Therefore, you must have confidence in who you are dealing with from the beginning to ensure the production of high-quality high-frequency PCB boards.
