Most purchasers in electronics factories often find themselves puzzled by the fluctuating prices of PCB boards. Even those with years of purchasing experience may struggle to fully grasp the reasons behind these changes. In reality, the pricing of PCB boards is influenced by several key factors:

1. The varying materials used in PCB construction contribute to price diversity. For instance, consider a standard double-sided board. The base materials typically include FR-4, CEM-3, and others, with sheet thicknesses ranging from 0.6mm to 3.0mm and copper thicknesses from ½Oz to 3Oz. These specifications significantly impact costs. Additionally, there are notable price differences in solder mask inks, such as between conventional thermosetting oil and photosensitive green oil, highlighting how material differences lead to varied pricing.

2. The diversity of production processes also affects PCB pricing. Different manufacturing methods incur distinct costs. For example, gold-plated versus tin-sprayed boards, the production of milled versus punched boards, and the choice between silk-printed and dry film lines all contribute to cost variations, resulting in a wide range of prices.

Here’s a refined version of your article while keeping the structure and meaning intact:



Third, the price diversity arising from the complexity of the PCB itself

Even with identical materials and processes, the varying complexities of PCBs can lead to different costs. For instance, if two types of PCBs have 1000 holes, one with a diameter greater than 0.6mm and the other with a diameter less than 0.6mm, the drilling costs will differ. Similarly, if two circuit boards are identical but have different line widths and spacings—one exceeding 0.2mm and the other falling below—it will also result in varying production costs. The more complex board typically has a higher scrap rate, inevitably driving up costs and creating price variability.

Fourth, differing customer requirements can lead to price variations

The expectations of customers directly influence the production efficiency of PCB manufacturers. For example, a board adhering to IPC-A-600E, class 1, may require a 98% pass rate, while class 3 could allow for only a 90% pass rate. This discrepancy translates into varying costs for the manufacturer, ultimately resulting in fluctuating product prices.

Fifth, price diversity due to different PCB manufacturers

Even for the same product, different manufacturers can incur varying costs due to their unique process capabilities and technical expertise. Many manufacturers favor gold-plated boards because of their simpler production processes and lower costs. However, some manufacturers may experience higher scrap rates when producing gold-plated boards. Consequently, they may opt to produce tin-sprayed panels instead, leading to lower quotations for those compared to gold-plated options.

Sixth, price differences linked to payment methods

Currently, PCB manufacturers often adjust the sustainable pricing of PCBs based on payment methods, with variations ranging from 5% to 10%. This adjustment contributes to the overall price differences observed in the market.

Seventh, regional disparities in pricing

In China, there is a noticeable price gradient from the south to the north, with distinct variations across different regions. This geographic factor also plays a significant role in price diversification.

From the above discussion, it becomes clear that the variability in PCB prices is influenced by inherent and unavoidable factors. This overview aims to provide a general price range for reference. However, specific pricing should still be discussed directly with PCB manufacturers.
