How much is the circuit board copy board?

The price of PCB copy board varies according to different boards and requirements. How to calculate the cost of copy board can refer to the following aspects.

1. Circuit board size

The size of the PCB board area, if it is an irregular shape circuit board, refers to the largest shape range. The size of the board has a tolerance range, and the size of the general shape tolerance is about +/-0.2 on one side.

2. The number of circuit board layers

Shenzhen Honglijie Electronics can provide copy boards of different layers such as 1-38 layers. Here refers to the 1 layer is a single panel, the 2 layer is a double panel, the 4 layer is a four-layer board, and the 6 layer is a 6-layer board! Generally speaking, the more layers of the PCB board of the same area, the higher the cost of copying the board.

3. Device density

The density of devices (resistance, capacitance, inductance, etc.) is directly related to the workload and difficulty of copying the board (the board with high device density must pay more attention when disassembling the components, recording the position number, and grinding the board), so the circuit board The cost of copying the board is also linked to the density of the board components. The higher the density, the higher the price of copying the board.

4. Difficulty of operation

The operation difficulty of the circuit board copying board is mainly related to the number of circuit board layers and device density at the two points above, as well as other aspects, such as the integrity of the board, the maximum board thickness, the minimum line width, the minimum line gap, and the minimum mechanical Through holes, smallest laser holes, smallest laser blind holes, types of blind holes, types of buried holes, copper thickness measurement and spacing measurement between multilayer boards, etc.

What are the factors that affect the cost of copying the board?

Different PCB copy board companies will have some differences in how much they charge for copying boards, but the cost of copying boards is mainly related to the size of the PCB board, the number of solder joints and the number of layers, and what items need to be done.

1. PCB board size

The size mainly affects the workload of copying the board. An indispensable part of the PCB copying process: polishing the PCB. The larger the board, the more time it takes to polish in Vietnam, and the greater the probability of damage to the original board, the larger the size., The cost of copying the board will be higher.

2. PCB layers

The number of board layers mainly affects the difficulty of copying the board. The more the number of board layers, plus the existence of various buried and blind holes, not only affects the speed of copying the board, but also increases the difficulty of copying the board. Therefore, the board layer The higher the number, the higher the cost of copying the board. (Multilayer board copy board)

3. PCB solder joints

The number of solder joints is related to the density of the device, and has an impact on the workload and difficulty of dismantling, template, and copying circuits. The more solder joints, the higher the cost of copying the board.

4. Copy board project

There are generally three kinds of files for copy board: PCB file, bom list, PCB schematic diagram (for details, please refer to: What are the copy board files?). Customers do not necessarily need these three documents every time they copy the board. Correspondingly, the fewer the document requirements, the lower the copy board cost. If there is a chip that needs a decryption program on the PCB, a certain chip decryption fee is generally required.

How to quote the PCB copy board?

Generally speaking, many companies not only provide circuit board copying, but also provide material purchasing and circuit board copying processing services. For customers, after the circuit board copying is completed, follow-up development, batch processing and other follow-ups are also required. For work, if you can choose the same copy board company to develop the entire process, you will also enjoy a certain discount, reduce the copy board price, or even copy the board for free.

Through the introduction of the above four different reference aspects, you can know how much the circuit board copy board is to be confirmed according to different PCB boards. The above is a narrow sense of PCB copy board quotation reference, sometimes not only need to clone the circuit board, but also need to make a BOM list, decrypt the chip, make a prototype or even mass production. Therefore, how much the circuit board copy board is not generalized.
