A customer contacted ACI Technologies regarding a high failure rate of their assemblies. They provided assemblies to be X-rayed and inspected for the purpose of identifying any process related issues such as (but not limited to) solder and assembly workmanship and evidence of damage due to moisture related problems during reflow (a.k.a. "popcorning"). Moisture damage usually appears as physical damage to the component. The first indication of moisture damage would be externally observable changes to the package in the form of bulging or fractures to the outer surface of the component, an example of which is shown in Figure 1. Internally observable indicators of moisture damage typically include fractures to the die inside the package and lifted or fractured wire bonds. These conditions would be apparent during transmissive X-ray inspection. Another symptom of moisture related damage would be inconsistent solder joint sizes that result from package deformation during the liquidus phase of the reflow process. None of these indicators of moisture related damage were present on the customer samples.

With hundreds of opportunities for problems to surface during the electronics manufacturing process, it is a credit to the manufacturing and engineering talent of the industry that planes fly, pacemakers keep hearts beating and phones are at the ready to provide Facebook updates or even make a call. To keep these dedicated professionals up-to-date on the latest causes and cures for assembly and solder defects, IPC and the U.K. National Physical Laboratory (NPL) have teamed up to sponsor a free webinar at 12:00 pm (noon) U.S. Central time on January 27, 2011 — a precursor to the hands-on, three-day Process Defects Clinic that will be held at IPC APEX EXPO in April.
