Passive Plus Inc. (PPI) has added an industry leading 100% automated CSAM (C Mode Scanning Acoustic Microscopy) internal inspection to all of its high power 2225, 3838, 6040 and 7676 capacitor series RF capacitors.

Internal defects in MLCC’s such as voids, cracks, de-laminations and electrode discontinuities can lead to short term or latent catastrophic failures. Typical MLCC electrical tests may not reveal these internal defects.

Cost effective high speed automation eliminates operator error, ensuring extremely high detection accuracy and repeatability.

The primary benefit of 100% CSAM internal inspection is increased reliability, by screening out electrically undetectable internal defects such as voids, cracks, de-laminations or electrode dis-continuities.
