Effect of Moon Phase on Tombstoning

  • Many factors play a role in the overall outcome of PCB assembly, especially when very small components are involved. Broadly speaking, tombstoning is a problem with very small 2-pin components (0201 caps and such) and we've filtered out the following challenges:
  • - proper paste application
  • - component placement
  • - designing for "good" thermal properties of the PCB with regard to tombstoning
  • - moon phase

Stretching Stainless Stencils? Oddity Today

  • Interesting manufacturing defect surfacing
  • Stencil “stretches” ever couple panels or so
  • Anyone ever seen or experienced this before?
  • Solutions? Next Steps?
