For “Internal voids in substrate microvia copper fill”, add details that may change the assessment order and check the basis and limits of each candidate.
Engineering conditions
First localize voids / seams in the microvia copper body before assembly, then compare pretreatment and electroplating histories by via geometry and location distribution. Unknowns remain unconfirmed. “Ready for assessment” means only that the method inputs are complete; it does not establish diagnosis or qualification.
Live assessment
First obtain pre-assembly intravia locations and batch maps.
Unconfirmed: Have pre-assembly voids / seams been localized to the copper-fill body in organic-substrate microvias?; Can via geometry, panel location, batch, and normal / abnormal sampling be correlated?First obtain via geometry, metallization evidence, and waiting / treatment traces.
Unconfirmed: Have pre-assembly voids / seams been localized to the copper-fill body in organic-substrate microvias?; Can via geometry, panel location, batch, and normal / abnormal sampling be correlated?; Are drilling, desmear, wetting / electroless copper, and waiting histories before copper filling traceable?First obtain shared via geometry and electroplating / solution-flow traces.
Unconfirmed: Have pre-assembly voids / seams been localized to the copper-fill body in organic-substrate microvias?; Can via geometry, panel location, batch, and normal / abnormal sampling be correlated?; Are current, additives / CVS, solution flow, and bath / equipment conditions comparable for the same via geometry?candidate solutions
The order changes only with conditions you confirm. Public information cannot establish suitability for your actual samples.
After one round of comparisons, choose the next step based on actual observations.
Results only change the order of the next investigation; they do not modify condition answers, prove a root cause, or qualify a solution.
Based on reported conditions and public sources. Ready to assess does not establish sample applicability or root cause. Order does not identify the best solution.
First obtain pre-assembly intravia locations and batch maps.
First obtain via geometry, metallization evidence, and waiting / treatment traces.
No result provided. Clarify key conditions before arranging an assessment.
ASE · Failure Analysis Lab ↗The service list does not guarantee detection rates at every RDL or microvia scale; sampling, structures, and destructive risks require confirmation.
MKS / Atotech · InPro SAP3 ↗Product capabilities apply to the specified system. They do not establish the cause of this batch's voids; do not directly adopt current density, via dimensions, or dimple values.
