Great Insights from the Market

Particle contamination leaves traces everywhere except in the instrument that is usually deployed to detect it. A particle counter positioned at the ISO 14644-1 sampling location measures concentration in the air at that point. It does not measure what settles on the product, what transfers from a fixture, or what happens during the six seconds a bond pad is exposed. The cases below describe what happened when organizations replaced the question “how clean is the air?” with the question that actually determines product outcome: “how many particles are reaching the surface, and when?”

At the request of the organizations involved, all cases have been anonymized. While identifying details have been removed, the measurements, findings and outcomes are presented accurately.

Each case follows the same structure. Recognition: the situation that existed before measurement began. Explanation: what the APMON data revealed that conventional monitoring had missed. Action: the specific changes made on the basis of that data, and the result. In every case, the investment in measurement was recovered through yield improvement, cost reduction, or contamination elimination — often within weeks of deployment.
