Typically, the largest and most volatile portion of the overall PCBA costs is the Bill of Materials (BOM).
BOM Line Items
It’s not just the total number of components that impacts the assembly cost, but the number of unique parts listed in the BOM. Every BOM line-item (or “part number”) incurs fees and subsequent overhead (sourcing/handling) that is attached to the handling and shipping of each unique part number.
Therefore, a design with 100 components and only 10 unique parts may cost significantly less to assemble than another with the same 100 components but 50 unique part numbers.
PCB Component Cost and Availability
A handful of unique, expensive components (e.g., high-end FPGAs, specialized sensors, powerful microprocessors) can easily dominate the total PCB assembly cost.
PCB component availability also matters: Can’t get that part, or it is “hard to find” – then it could increase procurement costs and introduce significant lead time delays.
The Advantage of Turnkey Component Sourcing
This is where working with a turnkey provider like XPtronics offers a substantial economic advantage. Leveraging XPtronic´s purchasing power and its large inventory of components in stock, customers benefit from reliable sourcing, lower part costs, and minimized project delays.
When designing your board, selecting components from XPtronics verified in-stock parts library ensures smoother procurement, faster PCB assembly, and more predictable overall PCBA costs.
