The price of PCB is a lot of buyers have been very confused things, many people place orders online will also question how these prices are calculated, let's talk about the components of PCB price.
1. the different materials used in PCB cause the diversity of prices
For example, the board generally has FR4 (Sheng Yi, Jiantao, Guoji, three prices from top to bottom), the board thickness ranges from 0.2mm to 3.0mm, the copper thickness varies from 0.5oz to 3oz, all of which cause a huge price difference in the board; In terms of solder resistance inks, there is also a certain price difference between ordinary thermosetting oil and photosensitive green oil.
2. different surface treatment processes cause the diversity of prices
Common are: OSP (antioxidant), lead spray tin, lead-free spray tin (environmental protection), gold plating, gold sinking and some combination processes, etc., the more expensive the price of the above process.
3. the price diversity caused by the different difficulty of PCB itself
There are 1000 holes on both types of circuit boards, and the hole diameter of one board is greater than 0.2mm and that of another board is less than 0.2mm will form different drilling costs; If the other two kinds of circuit boards are the same, but the line width and line distance are different, one is greater than 4mil, and one is less than 4mil, it will also cause different production costs; Secondly, there are some designs that do not follow the ordinary plate process, such as half holes, buried blind holes, disc holes, and carbon oil printing by the keyplate.
4. the different thickness of copper foil causes the price diversity
Common copper platinum thickness: 18um (1/2OZ), 35um (1OZ), 70um (2OZ), 105um (3OZ), 140um (4OZ), etc., the more expensive the copper foil thickness is.
5. the customer's quality acceptance standards
Commonly used are: IPC2, IPC3, enterprise standards, military standards, etc., the higher the standard, the higher the price will be.
6. Mold fee and test rack
6.1. mold costs, templates and small batches of the general board factory is the use of drilling and milling shape, there will be no additional milling costs, in large quantities, it is required to open the mold and punch the plate, so that there is a set of mold costs, the board factory is generally quoted at 1000 yuan.
6.2. Test fee: The sample is generally used for flying needle test, and the board factory generally charges test fees ranging from 100-400 yuan; Batch is to open the test rack to test, the general price of the test rack plate factory is between 1000-1500 yuan.
7. Price differences caused by different payment methods
Payment methods that take less time to arrive, such as cash, will have lower prices.
8. Order quantity/delivery time
8.1. the less the number, the more expensive the price is, because even if you do 1PCS, the board factory has to do engineering information, film, which process is indispensable
8.2. Delivery date: the data delivered to the PCB factory should be complete (GERBER data, the number of layers of the board, the board, the board thickness, the surface treatment, the ink color, the character color and some special requirements should be written clearly)
Through the above discussion, it is not difficult to see that the diversity of PCB processing prices has its inherent inevitable factors, this article can only provide a rough price range for reference, the specific price of course, or direct contact with the manufacturer.
