1.The materials used in the audio circuit pc board are different

　　Taking ordinary double-sided boards as an example, the plates generally have FR-4, CEM-3, etc., the plate thickness varies from 0.6mm to 3.0mm, and the copper thickness varies from 1Oz to 3Oz, resulting in huge differences in plate prices; in terms of solder mask ink, There is also a certain price difference between ordinary thermosetting oil and photosensitive green oil, so different materials lead to the diversity of prices.

　　2.The audio circuit pc board adopts different production processes

　　Different production processes result in different costs. For example, gold-plated plates, tin-sprayed plates, gong (milling) plates, beer (punching) plates, screen printing lines, and dry film lines form different costs, resulting in price diversity.

　　3. The difficulty of the audio circuit pc board itself is different

　　Even if the material and process are the same, the pc board itself will cause different costs.

　　4.Customer requirements are different

　　The level required by the customer will directly affect the yield of the audio circuit pc board factory.

　　5. Audio circuit pc board manufacturers are different

　　Even the same product will form different costs due to the process equipment of different audio circuit pc board manufacturers.

　　6. Different regions

　　At present, from the geographical point of view, from south to north, the price is on the rise, and there are certain differences in the price of audio circuit pc boards in different regions, so different regions also lead to price diversity.
