Overview

Xray inspections, IR Rework, and Visual Inspections

Lead Free Rework

Successful rework and assembly methods have been developed with lead-free solders for all types of components. During the transition period to lead-free manufacturing rework practices have to be developed that deal with the issues related to handling, reworking, tracking and inspecting lead free PCB assemblies.

XRAY Inspection

A strong supplemental tool to XRAY, a boroscopic inspection tool, allows hidden solder joint or joints that are in close proximity to other nearby parts to be inspected and characterized. BEST has the capability to inspect and troubleshoot process defects through the use of this tool.

XRAY Inspection

Visual Inspection

XRAY imaging is a widely utilized analytical tool for the SMT PCB manufacturing process. In PCB assembly area array packages such as CGA, BGAs and CSPs with their concealed solder joints, have become the main field of application for X-ray inspection.

Visual Inspection 

AOI-inspection

As the complexity of electronic assemblies has increased and the corresponding miniaturization of components populating those assemblies have shrunk.
