When many customers are looking for PCB manufacturers to make samples through the Internet, they are always worried about accidentally finding expensive manufacturers. So, what are the factors that affect the price of PCB circuit board proofing? Let me explain to you in detail below:
—, board factors:
1. Different board materials have different prices.
2. The thickness of the plate, the common ones are: 0.4, 0.6, 0.8, 1.0, 1.2, 1.5, 1.6, 2.0, different thicknesses, different prices.
3. The thickness of copper and platinum will affect the price. The thickness of copper and platinum is generally divided into: 18um (2/1oz), 35um (1oz), 55um (1.5oz), 70um (2oz), etc.
4. The suppliers of raw materials are different, and the commonly used ones are: Shengyi/Jiantao/International, etc.
二. Process cost:
1. The smaller the line width and line spacing of the circuit on the PCB, the more expensive the price.
2. If the board has BGA, the cost will increase accordingly.
3. The surface treatment process is different, and the price will be different. The common ones are: spraying lead-tin (hot air leveling), OSP (environmental protection board), spraying pure tin, tin, silver, gold, etc.
4. The higher the process standard, the higher the price. Commonly used is: IPC2 level, but some customers have higher requirements, such as: IPC2, IPC3, enterprise standard, military standard, etc.
5. For some products such as blind buried hole board, immersion gold board, chemical gold board, etc., due to the particularity of the process or material, special calculation methods must be used.
6. Others: expedited fee, imposition fee, flying probe test fee, etc.
In short, the price calculation of PCB circuit board proofing is the most special and complicated in all industries, and the standard rate of the process will be different for different types of products. In addition, when choosing a pcb board manufacturer, you should not choose only from the price point of view, but compare the strength of the manufacturer, approximate product quotations, and service items.
