Epoxy Cure Batch Calculator

Epoxy cure capacity depends on fixture loading, oven profiles, adhesive pot life, cure cycles, and post-cure rejects. This calculator estimates good cured assemblies per shift or lot after uptime and yield losses.

What this calculator does

  • Estimate good epoxy-cure batch output from connector capacity per cure cycle, available cycles, oven uptime, and post-cure yield.
  • Use it when planning connector epoxy cure, ferrule bonding, pigtail attach, strain relief bonding, or photonic assembly adhesive cure capacity.
  • Estimates good output from an epoxy or adhesive cure batch process.

Formula used

  • Gross epoxy cure capacity = assemblies per cure cycle × available cure cycles
  • Good epoxy cure output = gross capacity × cure station uptime × post-cure accepted yield

Inputs explained

  • Assemblies loaded per cure cycle: Use the number of connectors, ferrules, pigtails, or modules loaded per oven or cure fixture cycle.
  • Available epoxy cure cycles: Enter planned cycles based on cure profile, loading time, shift length, and adhesive pot-life limits.
  • Cure oven or station uptime: Account for warm-up, fixture availability, cleaning, maintenance, and recipe changeover.
  • Post-cure accepted yield: Use the share expected to pass after cure, pull check, geometry, visual inspection, and optical test.

How to use the result

  • Use it to size cure ovens, fixtures, batch release timing, WIP buffers, and capacity for connector or photonic assembly bonding.
  • It does not determine cure profile, adhesive mix ratio, or pot life; follow the adhesive, process, and customer specifications.

Common questions

  • What counts as one cure cycle? One complete load, cure, cool, and unload sequence for the oven, hot block, UV cure station, or fixture being evaluated.
  • What should post-cure yield include? Include rejects from pull checks, voids, epoxy contamination, fiber movement, endface issues, geometry, and optical test failures after cure.
  • Why include uptime for a batch process? Warm-up, fixture cleaning, recipe changeover, maintenance, and waiting for material can reduce practical cure capacity.
  • What decision does this support? Use good output to schedule batches, justify fixtures or ovens, and confirm whether cure capacity supports the assembly plan.
