Double-Sided HASL PCB Price Hike
| Raw Material Category | Consumption Composition/Configuration Standard | Actual Consumption per 1㎡ | Remarks |
|---|---|---|---|
| Copper | 1. Substrate copper foil (18μm thick on both sides)
2. Electroplated copper balls (conductive path supplement) |
0.3214kg (substrate) + 0.33kg (electroplating) = 0.6514kg/m² | Includes 25% etching loss and plating bath loss; mainstream industry configuration |
| Tin | 1. Circuit tin plating (etching resist layer)
2. HASL tin spraying (surface finish, 9x loss factor) |
0.05kg (circuit tin plating) + 0.066843kg (HASL) = 0.116843kg/m² | HASL calculated at 10% tin-plated area and 200μin thickness; standard mass production loss factor |
| PP (Prepreg/Glass Cloth) | Routine configuration for 1.6mm double-sided PCBs | 7 sheets/m² | 1 sheet of PP can produce 1㎡ finished board; industry-universal ratio |

| Raw Material Category | Pre-Sept 2025 Price (CNY) | Post-Sept 2025 Price (User-Specified, CNY) | Price Increase (CNY) | Price Increase (USD) | Increase Rate |
|---|---|---|---|---|---|
| Copper | 78,000 元 /ton (78 元 /kg) | 102,000 元 /ton (102 元 /kg) | 24 元 /kg | 3.31 USD/kg | 30.77% |
| Tin | 270,000 元 /ton (270 元 /kg) | 460,000 元 /ton (460 元 /kg) | 190 元 /kg | 26.22 USD/kg | 70.37% |
| PP (Prepreg) | 13 元 /sheet | 15 元 /sheet | 2 元 /sheet | 0.28 USD/sheet | 15.38% |
Price Calibration: Copper and tin prices are converted from “CNY/ton” to “CNY/kg” and “USD/kg” to avoid calculation errors; PP prices are calculated based on the user-specified standard of “1 sheet = 1㎡ finished board,” aligning with procurement practices.
Price Hike Drivers: Copper and tin price surges stem from Indonesian tin ore export restrictions and booming demand from AI/ne 新能源 sectors; PP price increases are due to tight supply of glass fiber raw materials—all widespread industry phenomena post-September.
| Raw Material Category | Consumption per 1㎡ | Unit Price Increase (CNY) | Unit Price Increase (USD) | Price Hike per 1㎡ (CNY) | Price Hike per 1㎡ (USD) | Calculation Process (CNY) |
|---|---|---|---|---|---|---|
| Copper | 0.6514kg | 24 元 /kg | 3.31 USD/kg | 15.63 | 2.16 | 0.6514 × 24 = 15.6336 ≈ 15.63 |
| Tin | 0.116843kg | 190 元 /kg | 26.22 USD/kg | 22.20 | 3.06 | 0.116843 × 190 = 22.19997 ≈ 22.20 |
| PP (Prepreg) | 7 sheets | 2 元 /sheet | 0.28 USD/sheet | 14.00 | 1.96 | 7 × 2 = 14.00 |
| Calculation Dimension | Price Hike per 1㎡ (CNY) | Price Hike per 1㎡ (USD) | Contribution Ratio | Key Impact Description |
|---|---|---|---|---|
| Copper Contribution | 15.63 | 2.16 | 30.1% | Large consumption but moderate unit price increase; stable contribution |
| Tin Contribution | 22.20 | 3.06 | 42.8% | Over 70% unit price increase, amplified by HASL loss; highest contribution |
| PP Contribution | 14.00 | 1.96 | 27.1% | Moderate single-sheet increase, but significant when multiplied by 7 sheets |
| Total Raw Material Hike | 51.83 (≈52 CNY/m²) | 7.18 (≈7.2 USD/m²) | 100% | Copper, tin, and PP only; no processing fees included |
Consumption Adaptability: Copper and tin consumption in this article is based on 1/2oz (18μm) copper thickness and partial HASL (10% area). For 2oz copper thickness or full-board HASL, consumption and price hikes double proportionally. PP consumption follows routine 1.6mm board thickness configuration; adjust sheet quantity for different thicknesses (e.g., 1.2mm/2.0mm).
Price Volatility Risk: Current tin (460,000 CNY/ton) and copper (102,000 CNY/ton) prices are at highs, with PP prices expected to rise further. PCB enterprises are advised to lock in costs via “long-term price agreements + bulk purchasing,” especially as tin prices remain volatile due to Indonesian policy changes.
Cost Boundary Clarification: This article only calculates price hikes for copper, tin, and PP. It excludes other auxiliary materials such as FR-4 core substrate and solder mask ink. The full raw material price hike for double-sided PCBs would increase by an additional 5-8 CNY/m² (≈0.7-1.1 USD/m²) to account for these excluded items.
