The prICe of PCB can be estimated. How to estimate the price?

PCB manufacturers, PCB designers and PCBA manufacturers explain that PCB prices can be estimated, and how to estimate prices

The price of PCB is always a puzzle for many buyers. Many people also question how these prices are calculated when placing orders online. Let's talk about the composition factors of PCB price.

The price of PCB can be estimated

1、 Different copper foil thickness leads to diversified PCB prices

Common copper platinum thickness: 18um (1/2OZ), 35um (1OZ), 70um (2OZ), 105um (3OZ), 140um (4OZ), etc. The copper foil thickness above will become more expensive in the future.

2、 The price of circuit board is different due to mold cost and test rack

(1) Mold cost, if the sample is SIMilar to the SMAll batch, the general plate factory will adopt the drilling and milling shape, and will not charge additional milling fees. When doing large batch, it is required to open the mold to punch the plate, so there is a set of mold cost, and the plate factory generally quotes 1000 yuan upwards.

(2) Test fee: generally, the sample is tested by flying needle, and the board factory generally charges a test fee ranging from 100 to 400 yuan; Test racks will be opened for batch testing. Generally, the quotation for test racks is 1000-1500 yuan.

3、 The diversity of PCB price due to different surface treatment processes

Common processes include: OSP (oxidation resistance), lead tin spraying, lead-free tin spraying (environmental protection), gold plating, gold deposition and some combination processes. The more the above processes cost, the more expensive the PCB becomes.

4、 The diversity of PCB prices due to different materials used in PCB

For example, for ordinary double-sided panels, the panel materials generally include FR4 (Shengyi, Jiantao and Guoji, with three prices from top to bottom), the panel thickness varies from 0.2mm to 3.0mm, and the copper thickness varies from 0.5oz to 3oz, all of which cause huge price differences in the panel materials; In terms of solder resist ink, there is a certain price difference between common thermosetting oil and photosensitive green oil.

5、 Order quantity/delivery date

(1) The smaller the quantity, the more expensive the price is, because even if it is to make 1 PCS, the board factory has to make engineering data and produce film, which process is indispensable.

(2) Delivery date: the data delivered to PCB factory shall be complete (GERBER data, number of layers of board, board, board thickness, what to do with surface treatment, ink color, character color and some special requirements shall be clearly written).

6、 Price difference of PCB caused by different payment methods

The shorter the time of arrival, such as cash payment, the lower the price.

7、 Customer's quality acceptance standards

Commonly used: IPC2, IPC3, enterprise standard, military standard, etc. The higher the standard, the higher the price.

8、 PCB price diversity caused by different PCB difficulties

There are 1000 holes on both kinds of circuit boards. If the hole diameter of one board is larger than 0.2mm and the hole diameter of the other board is smaller than 0.2mm, the drilling cost will be different; If the other two types of circuit boards are the same, but the line width and line spacing are different, one is greater than 4mil, and the other 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, holes in the plate, and carbon oil printing on the key plate.

It is not difficult to see from the above discussion that the diversity of PCB prices has its inherent inevitable factors. This article can only provide a general price range for reference, and the specific price is of course directly related to the manufacturer.
