[Data] How to charge for PCB copy board?

Printed circuit boards {Printed circuit boards}, also known as printed circuit boards, are providers of electrical connections for electronic components.

There are three processes for PCB copy board: 1, PCB drawing board; 2, reverse push schematic diagram; 3, BOM (bill of materials) production. After completing the board copy process, there will be three corresponding files: PCB, SCH, and BOM. PCB copy board does not take too long. General dismantling: 0.5-3 hours, polishing 0.5-2 hours, drawing board: more than 1 hour.

Regarding the question of how the PCB copy board is generally charged. Some companies are calculated based on points (single and double panels: 0.5-0.7 yuan per point; four-layer boards: 0.8-1.0 yuan per point, 6-layer boards 1.0-1.2 yuan per point, 8-layer boards 1.2-1.5 yuan per point ), most companies estimate the price based on experience. No matter what method is used for quotation: points are only for reference. Generally, the above PCB copy board workload is used to calculate the price of PCB copy board.

PCB copy board valuation method:

1. Demolition price: According to the type, quantity and difficulty of the board components, the price of demolition is between 50-150 yuan.

2. Polishing board price (for multi-layer boards): Calculated according to the size of the board, the larger the board, the larger the area to be ground and the longer the time period. The price of the grinding plate is 50-100 per layer.

3. The price per point, regardless of the number of layers. The price is roughly 0.5-0.6 yuan per point. Because the number of layers may affect the number of points (generally, there are more points with more layers), but the number of layers does not affect the price of points.

4. The price of the middle layer: because the multi-layer board also needs to draw the middle layer, because there is no need to place components and other reasons, the middle layer drawing time is generally 0.5-2 hours, and the price of each layer is about 50-100 .

The scope of application of PCB copy board quotation: covers 90% of the industry. For boards that are too simple or too complex, or have workloads that are not included in the above: if there is no silk screen, you need to re-screen the screen (if the silk-screen is not clear, you must re-screen the screen for the accuracy of the document), and the board is covered with black Special circumstances such as glue (the work required to process vinyl is also relatively large), etc., must be increased or decreased according to the actual situation.

The price of the schematic and BOM is generally determined according to the schematic and the number of layers. The price calculation of the schematic diagram is relatively simple, according to the board with different layers of 1-1.2 yuan per point. The price of BOM is between 100-500 according to the quantity and difficulty of the material (BOM some IC codes and some models cannot be known, and the cost of checking the code is required to find a professional code-checking company. Customers can also go through their own channels. solve)
