Consigned Kits against Turnkey Purchasing on the Same Board
Split procurement saves component markup fees on high-cost ICs but demands strict kit audits, overage management, and clear contract defect attribution rules.
Setup Hour Pricing
Production Overhead
Non-recurring charges cover the time required to configure machinery and initialize software workflows before the manufacturing of a specific printed circuit board assembly begins. Setup hour pricing aggregates these front-end expenses into a discrete hourly rate applied to each distinct production run. Vendors calculate this amount by combining operator wages, machine idle time, and the depreciation of specialized tooling fixtures required to load the components into the feeders.
The figure ends where the automated pick and place equipment starts the high-speed placement cycle.
Machine Calibration
Calibration tasks involve manual adjustments to the solder paste stencil alignment and the programming of optical inspection sensors to recognize individual board geometries. This phase demands technical personnel to verify that feeder coordinates match the master data file to prevent mounting errors. Failure to achieve precise alignment results in skewed components or shorts during the reflow stage, necessitating a full re-initialization of the line.
Precise verification of the placement accuracy serves to validate the investment made during these initial operational hours.
Contract Allocation
Procurement departments manage these expenses by amortizing the total cost over the entire volume of a purchase order to minimize the impact on the unit cost of small batches. High volume production lowers the per-unit burden as the cost of the initial preparation remains constant regardless of whether the line produces ten or ten thousand units. Low volume fabrication requires frequent changes to the line, which causes the cumulative cost of repeated cycles to rise proportionally.
Buyers often negotiate a fixed fee for these activities rather than an open hourly rate to ensure predictable manufacturing budgets.
