Solder Paste Usage at 94% paste usage efficiency: a worked example
This scenario runs the solder paste usage calculation on the strong side: 94% paste usage efficiency, with every other input held at its documented default. a process engineer or buyer needs enough paste for an SMT build without over-ordering
The inputs for this scenario
- Boards or panels to print: 1,800 boards or panels (unchanged)
- Solder paste per board or panel: 0.42 g / item (unchanged)
- Paste usage efficiency: 94 % (raised for this scenario; the documented default is 82)
Working through the calculation
- Applying the documented formula (Theoretical paste deposited = boards or panels to print × solder paste per board or panel) to the inputs above produces each figure below.
- At this operating point the engine returns 804 g for required solder paste, the number this scenario is built around.
- At this operating point the engine returns 756 g for theoretical paste deposited.
- At this operating point the engine returns 48.26 g for paste waste allowance.
- At this operating point the engine returns 94 % for paste usage efficiency.
How this compares with the baseline
- Against the tool's baseline example, where paste usage efficiency sits at 82% and the headline result is 922 g, this scenario comes in 12.77% below the baseline at 804 g.
- Use it when ordering paste for a known build quantity, sizing a kanban bin at the printer, or comparing paste consumption across product lines. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
