How Engineers Save Costs Through BOM Consolidation in PCB Design
How Engineers Save Money Before Manufacturing Even Begins
Designing a schematic is only the first step in bringing a product to life. Once the circuit is ready and footprints are assigned, there’s an additional optimization process engineers can take to significantly reduce costs: BOM consolidation.
During this stage, engineers review the Bill of Materials to identify common components — resistors, capacitors, and other passives — and group them strategically to avoid unnecessary variety. The fewer unique parts you use, the more efficient your procurement and assembly become.
A Practical Example: Consolidating Resistor Values
Imagine a design with an IC using I²C communication and 2.2kΩ pull-up resistors. The same board might also include a 2kΩ current-limiting resistor for an LED. By reviewing the BOM, the engineer might realize that using a single 2.2kΩ resistor for both purposes would still meet the circuit’s requirements while eliminating one unique component from the list.
These small adjustments may seem insignificant individually, but they add up quickly across larger assemblies — saving both component sourcing time and manufacturing cost.
Why BOM Consolidation Matters
BOM consolidation works because of two key principles:
1. Economies of Scale:
When you purchase higher quantities of a single component, you often receive better pricing — even for relatively small orders through suppliers like Digi-Key or Mouser.
2. Manufacturing Efficiency:
Each unique component requires its own reel to be loaded onto the pick-and-place machine. Fewer component types mean fewer reel changes, less setup time, and reduced waste during automated placement.
“Every component you eliminate is one less reel, one less changeover, and one less opportunity for waste.”
The Design Decision Factor
Of course, BOM consolidation must always balance design intent and performance. Not every resistor or capacitor can be substituted — it’s about making informed decisions where the change won’t compromise circuit functionality. This process requires both engineering judgment and experience with production workflows.
