How to charge for PCB circuit board proofing

With the continuous development of The Times, the current type of electronic products is more and more, so PCB circuit boarddesign engineers in the early design, in order to determine the feasibility of the program, will keep on the circuit board proofing test, then circuit board proofing is how to charge, the following Xiaobian to say in detail.

Circuit board proofing how to charge

Circuit board proofing, is generally in accordance with the engineering fee + board fee + test fee + film fee, specific is based on the customer provided information and process requirements to charge. For example: the number of boards, process requirements, ink color, board thickness, board way, degree of difficulty, delivery time and so on, a comprehensive assessment of the price, here is a special price board and non-special price board how to charge.

1, special price board charges

The board layer is single and double panel, the material is FR4, the size of length and width is less than 10*10cm, the board thickness is required to be between 0.8 and 1.6mm, the process is required to be ordinary tin spray, the ink color is green oil and white characters, the quantity is less than 10PCS, the minimum line width and line distance is 0.15mm/0.15mm, the minimum aperture is 0.3mm.

As long as meet the above special price of standard PCB board proofing prices are 50 yuan, no free shipping.

2, non-special price board charges

The board layer is single and double layer, the material is FR4, the size of the length or width has exceeded 10cm on one side, the board thickness is required to be between 0.8-1.6mm, the process is required to be ordinary tin spray, the ink color is green oil and white characters, the quantity is less than 10PCS, the minimum line width and line distance is 0.15mm/0.15mm, and the minimum aperture is 0.3mm.

As long as the length or width of any side is more than 10cm, the pcb board proofing fee should be executed according to the following. Engineering fee 50 yuan + board fee, such as size according to 20*20cm to calculate, the unit price is 0.05 yuan/square centimeter, so that is 20(length)*20(width)*0.05(unit price)=20 yuan, and then 20 yuan (single price)*10PCS(quantity)=200 yuan, engineering fee 50 yuan + board fee 200 yuan =250 yuan, Then the pcb proofing cost of this type beyond the special price range is 250 yuan.

Specific or need to see the data in order to quote the price, because it also involves some small holes and other uncertain factors.

PCB circuit board proofing offer

In the current physical processing industry is more and more difficult, the price of the product has become most business owners and procurement are more concerned about the issue, the electronic industry circuit board proofing is the same, but some business owners do not understand the circuit board proofing quote, the following Xiaobian to say in detail.

PCB proofing quotation

1. Different plates cause different quotations

To plate FR4 as an example, general life benefit, Jian Tao, Guo Ji three, the price is not the same; Plate thicknesses range from 0.2mm to 3.0mm, and copper thicknesses from 0.5oz to 3oz, all of which create huge price differences; In terms of solder resistance ink, ordinary thermosetting oil and photosensitive green oil also have a price difference.

2. Different surface treatment processes lead to different quotations

Common are: OSP(antioxidant), lead spray tin, lead-free spray tin (environmental protection), gold plating, gold sinking, etc., the price of these processes is more expensive.

3, the difficulty of the circuit board itself caused by different prices

For example, there are 1000 holes on both circuit boards. If the aperture of one board is greater than 0.2mm, and the aperture of the other board is less than 0.2mm, different drilling costs will be generated. If the others are the same, but the line width and line distance are different, one is greater than 4mil and the other is less than 4mil, it will also cause different production costs. In addition, there are some special processes are also charged money, such as half hole, buried blind hole, plate hole, etc.

4. Different copper foil thickness causes different prices

Common copper platinum thickness: 18um(1/2OZ), 35um(1OZ), 70um(2OZ), 105um(3OZ), 140um(4OZ), etc.; The thicker the copper foil, the more expensive it is.

5. Customer's quality acceptance standard

Commonly used are: IPC2, IPC3, enterprise standard, military standard and so on, the higher the standard, the higher the price will be.

6. Mold fee and test rack

1. Mold cost: The template is required to open the mold and punch the plate when doing a large quantity, so that there is a set of mold cost.

2, test fee: the sample is generally used to fly needle test, batch to open the test rack to test, need to charge the corresponding test fee;

7. Quantity and delivery time will also affect the price

The smaller the quantity, the more expensive the price; The shorter the delivery time, beyond the normal production schedule, need to pay extra urgent fee.

The following examples of two common types of circuit board prices

1. Special price board

The board layer is single and double panel, the material is FR4, the size of length and width is less than 10*10cm, the board thickness is required to be between 0.8 and 1.6mm, the process is required to be ordinary tin spray, the ink color is green oil and white characters, the quantity is less than 10PCS, the minimum line width and line distance is 0.15mm/0.15mm, the minimum aperture is 0.3mm.

As long as the above special price board standard circuit board proofing prices are 50 yuan, no free mail.

2, non-special price board

The board layer is single and double layer, the material is FR4, the size of the length or width has exceeded 10cm on one side, the board thickness is required to be between 0.8-1.6mm, the process is required to be ordinary tin spray, the ink color is green oil and white characters, the quantity is less than 10PCS, the minimum line width and line distance is 0.15mm/0.15mm, and the minimum aperture is 0.3mm.

As long as the length or width of any side is more than 10cm, the pcb board proofing fee should be executed according to the following. Engineering fee 50 yuan + board fee, such as the size of 15*16m to calculate, the unit price is 0.05 yuan/square centimeter, then 15)*16)*0.05(unit price)=12, and then 12 single piece price)*10PCS(quantity)=120 yuan, engineering fee 50 yuan + board fee 120=170 yuan, Then this is beyond the special range of circuit board proofing price cost of 170 yuan.
