The task at hand:

Verification of pin alignment in production of electronics

The client manufactures electronic assemblies and complete systems for communication equipment. In the course of the process, boards and pins are mutually connected. It is essential that the pins of the connectors are not misaligned, deformed or warped. A corresponding pin alignment inspection before shipment could only be performed manually.

Pin alignment inspection in production of electronics

The challenge

Inspection by video cameras is extremely difficult, as the 3D measurement is disturbed by reflections. The pins are often located at hidden positions with difficult access even for the light of laser line triangulators. The only possibility consists in a laser sensor with low form factor, able to check pin alignment with the narrow space available.

The QuellTech Solution

The Q4-5 Line triangulator is mounted on a linear axis, which itself is fixed to a robot arm. The robot arm positions the linear axis over the pins to be measured. After positioning, the linear axis translates the scanner on a path located at a certain distance above the pins. In the course of the travel, the position of the pins within the corresponding swash circumference is inspected and correct pin alignment is registered. The result (pass/fail) is determined and documented by the software.

Result for the Client

The testing system on the basis of the Q4-5 line triangulator has clearly proven its superiority with respect to the manual inspection carried out beforehand. Error rates could considerably be lowered. Furthermore, the system includes the documentation for quality control of the lot, contributing to an increased customer satisfaction as well.
