At AiPCBA, if you want to get PCB quotation, you only need to input the number of boards / thickness / layers of boards / size of boards, and get the quotation through online pricing system. Transparent price, supply regular materials, help customers achieve zero inventory. SMT patch is free of engineering cost and startup cost.

When you enter PCB Manufacturing Online Quote on AiPCBA website, firstly uploading Gerber file. Update the project name and make it easier to be identified and managed. States the exact quantity of pieces. Select layers, dimension and PCB thickness (mm). Choose the side Direction, Tech Border and Board Types. Min Track/Spacing (mil), Min Hole Size(mm) , the color of Solder Mask, Silkscreen, the types of Surface Finish, Via Process, Outer Copper, Test Points, test methods, Impedance, Half Hole status, PCB Lead Time and PCB Remark should also be inputed exactly in order to preview a perfect Gerber 3D view.

How to calculate PCB quotation?

1. Plate cost (different plate cost is different)

2. Drilling cost (the number and size of holes affect the drilling cost)

3. Process cost (different process requirements of the board lead to different process difficulties and even different prices)

4. Artificial water and electricity plus management cost (this cost depends on the cost control of each factory, and Taiwan funded factories are relatively low in many countries)

PCB price is composed of the following factors

1) Different materials used in PCB cause price diversity

Take the common double-sided board for example, the board materials generally include FR-4, CEM-3, etc., the board thickness varies from 0.6 mm to 3.0 mm, and the copper thickness varies from frac12; oz to 3 oz, all of which cause a huge price difference in the board material; in the solder resist ink, the common thermosetting oil and photosensitive green oil also have a certain price difference, so the different materials cause the price diversity

2) The difference of PCB production technology results in the diversity of price

Different production processes will cause different costs. For example, gold plating plate and tin spray plate, Gong (milling) plate and beer (punching) plate, silk screen printing line and dry film line will form different costs, resulting in a variety of prices.

3) Price diversity caused by different difficulty of PCB itself

Even if the materials are the same and the process is the same, the different difficulty of PCB itself will lead to different costs. For example, if there are 1000 holes on two kinds of circuit boards, the hole diameter of one board is greater than 0.6 mm and the hole diameter of the other board is less than 0.6 mm, different drilling costs will be formed; if the other two kinds of circuit boards are the same, but the line width and line distance are different, one is greater than 0.2 mm, the other is less than 0.2 mm, which will also cause different production costs, because the board with great difficulty has a high scrap rate, the inevitable cost will be increased, and then the production cost will be increased The diversity of price.

4) Different customer requirements will also result in different prices

The level of customer's requirements will directly affect the yield of the board factory. For example, according to ipc-a-600e, class 1 requires a 98% pass rate, but according to class 3, only 90% pass rate is possible, resulting in different costs of the board factory, and finally the product price changes.

5) Price diversity caused by different PCB manufacturers

Even if the same product is produced by different manufacturers with different process equipment and technical level, there will be different costs. Nowadays, many manufacturers like to produce gold-plated plates, because the process is simple and the cost is low. However, some manufacturers also produce gold-plated plates, which will rise when they are scrapped, resulting in higher costs. Therefore, they prefer to produce tin-plated plates, so their quotation for tin-plated plates is higher than that for gold plate.

6) Price differences due to different payment methods. At present, PCB manufacturers generally adjust PCB prices according to different payment methods, ranging from 5% to 10%, which also causes price differences.

7) Regional differences lead to price diversity

At present, in terms of geographical location, prices are increasing from south to North in China, and there are certain differences in prices in different regions, so different regions also cause price diversity
