Teach you how to accurately calculate the price per square meter of the printed circuit board!

Oneseine, a one-stop PCBA smart manufacturing manufacturer, will tell you today what are the calculation methods for the unit price of the circuit board? The calculation method of the unit price of the circuit board. In the electronics manufacturing industry, the circuit board (printed circuit board, referred to as PCB) is the basic component of electronic equipment, and its price calculation involves multiple factors. For the purchasing personnel of electronic equipment manufacturers, understanding the calculation method of the unit price of the circuit board and the market price range is crucial for cost control and procurement decisions. This article will explore the calculation method of the unit price of the circuit board in depth and give a general price range for reference.

Calculation method of the unit price of the circuit board

1. Factors for calculating the unit price of the circuit board

The unit price of the circuit board is not fixed, but is affected by many factors, mainly including the following points:

1. Material cost

The main materials of the circuit board include substrates (such as FR4, CEM-1, aluminum substrates, etc.), copper foil, and solder mask ink. The cost and performance differences of different materials will cause fluctuations in the price of the circuit board.

2. Process complexity

The manufacturing process of the circuit board includes cutting, drilling, copper plating, circuit making, solder mask, text and solder mask, electroplating, tin spraying and other steps. The complexity of the process will directly affect the manufacturing cost, and then affect the unit price.

3. Number of layers and thickness of the board

Multilayer circuit boards are more complex than single-layer or double-layer circuit boards, so the cost is also higher. At the same time, the thickness of the board will also affect the price. Thick boards usually require more materials and more complex processes.

4. Size and shape

Large-sized or special-shaped circuit boards require more raw materials, and may also increase the difficulty of production, thereby affecting the price.

5. Production batch

Large-scale production can usually reduce unit costs, while small-scale or customized production may lead to higher unit prices.

6. Design complexity

The more complex the circuit design, such as high-density wiring, fine pitch, etc., the higher the manufacturing cost.

7. Surface treatment technology

Different surface treatment technologies such as hot air leveling (HASL), chemical nickel gold (ENIG), and electroplated nickel gold (Hard Gold) have different costs and effects.

8. Other special requirements

Special requirements such as impedance control and blind buried holes will also increase the production cost of circuit boards.

2. General range of circuit board prices

Due to the influence of the above factors, there are great differences in the prices of circuit boards. The following are the approximate price ranges of some common types of circuit boards (for reference only):

1. Single-layer circuit boards

Usually used for simple electronic devices, the price is relatively low. Generally speaking, the price of a single-layer circuit board may range from tens to hundreds of yuan per square meter.

2. Double-layer and multi-layer circuit boards

As the number of layers increases, the price will also rise accordingly. The price of a double-layer circuit board may be 1.5 to 2 times that of a single-layer board, while the price of a multi-layer board (4 layers, 6 layers or more) will be higher.

3. Special materials and processes

If high-performance materials or special processes (such as metal-based circuit boards, high-frequency boards, buried blind holes, etc.) are used, the price will be significantly higher than that of ordinary circuit boards.

4. Customized circuit boards

For circuit boards that require customized design, small batch production or special requirements, the price is usually higher because it involves more R&D costs, mold costs and manufacturing costs.

III. How to get a more accurate quote

In order to get a more accurate quote for circuit boards, procurement personnel can take the following measures:

1. Clarify the needs

Before asking for a quote, clarify the specifications, materials, number of layers, size, process and other requirements of the required circuit boards.

2. Compare prices from multiple suppliers

Ask multiple circuit board suppliers for prices and services.

3. Provide detailed information

Provide suppliers with detailed circuit board design drawings, technical requirements and production quantities so that suppliers can give more accurate quotes.

4. Understand the market situation

Pay attention to market trends and understand the impact of factors such as raw material prices and exchange rates on circuit board prices.

5. Establish long-term cooperative relationships

Establishing long-term and stable cooperative relationships with suppliers will help you get more favorable prices and better services.

As an indispensable part of electronic equipment, the price of circuit boards is affected by many factors. It is crucial for purchasers to understand these factors and learn how to get accurate quotes. By clarifying needs, comparing prices with multiple suppliers, providing detailed information, understanding market conditions, and establishing long-term cooperative relationships, you can effectively control costs and make wise purchasing decisions.
