BGA Reball/Reflow Labor Cost at 92% boards requiring reball and reflow: a worked example

Push boards requiring reball and reflow up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when bga reball/reflow labor cost in electronics repair, refurbishment and depot operations is being put through a electronics repair, refurbishment and depot operations weighted-cost review.

The inputs for this scenario

  • Boards routed to reball/reflow: 100 boards (unchanged)
  • Labor cost per reball/reflow board: 45 $ / board (unchanged)
  • Boards requiring reball/reflow: 92 % (raised for this scenario; the documented default is 80)
  • Fixed fixture, stencil, or X-ray cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable reball/reflow labor cost = boards routed to reball/reflow × labor cost per reball/reflow board × boards requiring reball/reflow) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total bga reball/reflow labor cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for reball/reflow labor cost per board.
  • At this operating point the engine returns 4,140 $ for variable reball/reflow labor cost.
  • At this operating point the engine returns 250 $ for fixed fixture, stencil, or x-ray cost.

How this compares with the baseline

  • Against the tool's baseline example, where boards requiring reball and reflow sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • It computes total reball/reflow labor cost for a batch and the average cost per board, combining per-board rework labor scaled by the share of boards needing reball plus fixed fixture, stencil, and X-ray cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
