CID Quality Control & Process Improvement 3

Question 1

IPC-6012 Class 3/A designation is specifically required for which type of interconnect application?

Accepted Answer

Space and military life-support

Answer

Class 3/A (formerly Class 3S) applies to space and military hardware where continued performance is critical and field repair is impossible.

Question 2

Which process improvement methodology uses PDCA cycles as its core iterative framework?

Accepted Answer

Kaizen / ISO Kaizen

Answer

Kaizen (continuous improvement) is built on the Plan-Do-Check-Act cycle for iterative, incremental process enhancement.

Question 3

What is the primary purpose of an Automated Optical Inspection (AOI) system in PCB fabrication quality control?

Accepted Answer

Detecting surface defects and dimensional deviations

Answer

AOI systems use cameras and image processing algorithms to detect surface-level defects such as opens, shorts, missing features, and dimensional deviations.

Question 4

In a control chart analysis, eight consecutive points on the same side of the center line indicate:

Accepted Answer

A process shift requiring investigation

Answer

Eight or more consecutive points on one side of the centerline is a run rule violation signaling a non-random process shift that requires investigation.

Question 5

Which IPC standard governs the design and performance requirements for rigid-flex PCBs?

Accepted Answer

IPC-6013

Answer

IPC-6013 specifies performance and qualification requirements for flexible and rigid-flex printed boards.
