What are the components of the board price

1, the material used in the PCB board is different, resulting in price diversity
For ordinary double-panel, for example, the sheet material generally has FR4 (shengyi, Jianye, Guoji, three prices from top to bottom), the thickness ranges from 0.2mm to 3.0mm, and the thickness of copper varies from 0.5oz to 3oz. All of these have caused huge price differences in the sheet material; in the case of solder resist inks, there is also a certain price difference between ordinary thermosetting oil and photosensitive green oil.

2, the surface treatment process is different, resulting in price diversity
Common ones are: OSP (anti-oxidation), lead-spray tin, lead-free spray tin (environmental protection), gold plating, immersion gold and some combination processes, etc., the more expensive the above process price.

3, the price diversity caused by the difficulty of the PCB board itself
There are 1000 holes on the two types of boards. If one board has a hole diameter greater than 0.2mm and the other board has a hole diameter of less than 0.2mm, different drilling costs will be formed. If the two boards are the same, but the line width is different, one The species are more than 4 mils, one is less than 4 mils, which will also cause different production costs. Secondly, some designs that do not take the ordinary board process are also added, such as half holes, buried holes, holes in the plate, buttons The board is printed with carbon oil.

4, the thickness of copper foil is different, resulting in price diversity
Common copper and platinum thicknesses are: 18um (1/2OZ), 35um (1OZ), 70um (2OZ), 105um (3OZ), 140um (4OZ), etc. The thickness of the above copper foil is more expensive.

5, customer quality acceptance criteria
Commonly used are: IPC2, IPC3, enterprise standard, military standard, etc. The higher the standard, the higher the price.

6, mold fee and test stand
(1) Mold cost, sample and small batches. If the general board factory adopts the drilling and milling shape, it will not add additional milling edge fees. When doing large quantities, it is required to open the mold punching plate, so there is a set of mold costs. The board factory generally quotes at RMB 1,000.
(2) Test fee: The sample board generally adopts the flying needle test. The board factory generally charges the test fee of 100-1000 yuan; the batch is to open the test rack to measure, and the test rack general board factory price is between 500-2000 yuan.

7. Price difference caused by different payment methods
The shorter the payment time, such as cash payment, the lower the price.

8, order volume / delivery
(1) The smaller the quantity, the more expensive the price is, because even if it is 1PCS, the board factory has to do engineering materials, and the film is out of the film.
(2) Delivery: The data delivered to the pcb factory should be complete (GERBER data, board number, board, board thickness, surface treatment, ink color, character color and some special requirements should be clearly written)
