PCBs are a core component in the electronics manufacturing industry, and cost control directly affects competitiveness. How can the custom PCB board cost reduced while maintaining quality?
This article systematically analyses drivers of PCB board price, covering core dimensions such as material cost ratio, design standards, manufacturing process, etc., and provides cost reduction strategies in phases (before, during, and after manufacturing). Whether you’re engineers, procurement decision makers, or business managers, follow ELE PCB to achieve double optimisation of efficiency and cost!
PCB Cost Drivers
First of all, let’s get a comprehensive understanding of the composition of PCB price. The proportion of direct material cost in the cost composition of PCB usually reaches about 60%, while the proportion of direct labour cost usually reaches about 15%. Manufacturing costs usually account for about 25%.
Due to the complicated PCB manufacturing procedures involved, it’s not easy to obtain a cheap PCB. Next, ELE PCB will analyse the costs incurred at each stage of the manufacturing process in detail and provide corresponding cost reduction strategies.
Pre-manufacturing: Design and Material Selection
Select Suitable Materials to Reduce Cost
Substrate
FR-4 is the most common substrate, but the high-frequency board (Rogers 4350B) is more expensive. The cost of double-sided boards is more than fifty per cent of total PCB costs. The main circuit board cost factors are:
- TG value: The TG170 will be more expensive than the TG130 by 8-10%, and the TG150 will be more expensive than the TG130 by 3-5%.
- Board thickness: 1.6 mm is conventional thickness. Every change of 0.4 mm will lead to cost fluctuations for each square metre.
- Utilisation: Generally speaking, the utilisation rate of regular double-sided boards should be ≥80%, and that of multilayer boards ≥75%. Below these rates, the cost will rise.
- Parameter performance: Special materials, especially high frequency and high speed (e.g. Rogers, Isola, Teflon).
In order to reduce PCB manufacturing price, the following substrate materials are recommended:
| Frequency | Recommend Material |
| ≤1 GHz | FR4 |
| 1~5 GHz | I-speed |
| RF Signals | Special RF Materials |
Copper Foil Thickness
The common thickness involves 18um (1/2 oz), 35um (1 oz), 70um (2 oz), etc. You’d better choose 1 oz copper foil, while 2 oz copper foil is $10~15/sqm more expensive than 1 oz foil.
Optimize Design to Reduce Compelxity
- Layer control: The more layers the PCB has, the more expensive it is. Four-layer boards are prioritised as they cost 40% less than six-layer boards. If you want to spend less money on manufacturing, try to reduce the layers of your PCB. At the same time, an odd number of layers should be avoided, as although the cost of raw materials for odd-layer PCBs is lower than for even-layer PCBs, the processing cost is 15% higher. Odd-layer PCBs are also prone to warping problems, resulting in extra PCB repair costs.
- Panelization: The PCB cost per square inch is calculated in different ways, depending on the processes and requirements involved. To save board material, the shape and gaps of circuit boards should be maximised, which is called panelization. The custom PCB cost can be reduced significantly by board panelization, which can reduce waste and manufacturing costs. Additionally, the panelization gaps are limited to 1.6mm for its V-cut lowest cost spacing.
While-manufacturing: Technology and Equipment Control
Controlling Process Accuracy to Reduce Processing Costs
- Wire width/space:The conventional process is 0.1 mm+, while accurate circuits of 0.05 mm require high-end manufacturing equipment (LDI equipment), which increases the cost.
- The number and diameter of vias: The price increases when the holes are less than 0.3 mm. The price also increases with the number of holes, as well as with special holes such as half-holes and PTH holes(6.0 mm+).
Using Economical Solder Resist Ink
Green ink is the cheapest, but white or black ink costs more. Matte ink is more expensive than glossy ink. Special colours, such as purple, orange, and transparent, are less often used and more expensive. Additionally, the brand of ink will also affect the price(e.g. Japan’s Sun, Britain’s Gosh, the U.S.’s Flint).
Choosing Cost-Effective Finishes
The commonly used surface treatment are OSP, Tin Spray, and Immersion Gold. These three processes are listed in order of cost, from lowest to highest. If it is not a high-frequency circuit board and there are no small-pitch components on the board, avoid the use of the immersion gold process and give preference to the least expensive and flattest OSP process.
Post-manufacturing
Right-Sizing Quality Control
The quality inspections to be carried out and their costs vary depending on the acceptance criteria. Common acceptable quality standards are:
- Unified international IPC standards: IPC-6012 Class 3 standards are 10–20% more expensive than regular Class 2 standards (testing ratio increased by 100%)
- Automotive standards (TS16949 certified)
- Military standards (military certification required)
- Aerospace standards (AS9001 certified)
You’d better choose standard according to your products and aviod excessive quality control.
Order Volume & Lead Time Optimization
The amount of the order, the lead time, the mode of payment, and other factors will all affect the cost in addition. Manufacturers provide stepped pricing according to order quantity, with higher volume PCB production resulting in cheaper unit prices.
Build Stable Supply Chain to Reduce Procurement Costs
Apart from controlling costs in the PCB design and manufacturing process, how else can you save money? Building a mature and stable supply chain is the right choice. Choose a core supplier that offers reliable quality at an affordable price for long-term cooperation, and take advantage of discounts through centralised purchasing. For example, Chinese suppliers are much lower-cost than American suppliers.
China vs. US PCB Suppliers: Cost Comparison
| Category | Chinese Suppliers | U.S. Suppliers |
| Cost Competitiveness | ✅ Lower labor costs, economies of scale reduce unit price ✅ Government subsidies (tax breaks, export rebates) | ❌ High labor costs (3-5× China) |
| Supply Chain Integrity | ✅ Localized supply chain (materials, equipment, chemicals) ✅ Industrial clusters | ❌ Key materials (e.g., high-end CCL) depend on imports ❌ Fragmented supply chain, lower efficiency |
| Production Scale | ✅ Global capacity share >50% ✅ Top players: >1M sqm/month | ❌ Focused on niche/high-end markets, limited small-batch capacity |
Sharing demand forecasts with manufacturers is another effective method to reduce inventory costs using the JIT (just-in-time) model. Introducing the ERP system to monitor the whole process of procurement, production and logistics, identifying cost wastage points and optimising them.

Conclusion
PCB cost optimisation is a systematic project that must be managed throughout the entire production chain, from design to production. We suggests combining material standardisation with the benefits of mass production to further cut costs.
Optimizing PCB costs requires a holistic approach across design, manufacturing, and supply chain. Implement these 3 proven strategies to slash expenses while maintaining reliability:
Design Smart – Minimize layers (4L preferred), optimize panelization, standardize materials (FR4 first)
Process Control – Choose economical finishes (OSP), avoid ultra-fine features (<0.05mm)
Supply Chain Synergy – Leverage volume discounts via long-term partnerships, adopt JIT inventory

FAQs
A1:
Consider choosing cheaper materials, simplifying the design and negotiating discounts with the manufacturer. Typically, high-volume orders will get a more favourable unit price.
A2:
The most common PCB thickness is 1.6mm, which is also the cheapest. If you need very thick or very thin board, the cost will increase substantially.
