Solder Paste Cost Per Board Calculator
Paste cost per board is small on many assemblies but can matter on large boards, fine-pitch designs, and expensive alloy systems. This calculator normalizes paste cost by board count for quote rollups and material variance checks.
What this calculator does
- Convert solder paste spend into cost per assembled board.
- an estimator needs solder paste cost per board for a PCB assembly quote
- Returns the solder paste material cost per good board.
Formula used
- Unadjusted paste cost per board = total solder paste cost ÷ good boards covered
- Solder paste cost per board = unadjusted paste cost per board × allocation or currency factor
Inputs explained
- Total solder paste cost: Use purchase or issued paste cost for the build, including alloy premium if applicable.
- Good boards covered: Use good assemblies produced or expected from the paste quantity.
- Allocation or currency factor: Use 1 unless only part of the paste cost applies or currency conversion is required.
How to use the result
- Use it in assembly quotes, material variance reviews, and stencil or alloy comparisons.
- It excludes stencil cost, printer labor, wipe solvents, inspection, rework, and scrap unless those costs are included in total paste cost.
Common questions
- What does the solder paste cost per board calculator tell me? It reports paste dollars per good PCB assembly.
- Which numbers should I enter? Use total paste spend, good board count, and an allocation factor of 1 unless the cost is shared or converted.
- How should I use the result? Use the result in cost rollups and to decide whether paste waste reduction is worth process engineering effort.
- When is this only an estimate? Treat it as a planning estimate when product mix, setup time, operator assist time, feeder readiness, inspection disposition, test escapes, scrap, or supplier yield differs from the data used for the inputs.
