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.

In order to keep up with industry demand, IPC has released amendments for J-STD-001F, Requirements for Soldered Electrical and Electronic Assemblies, and IPC-A-610F, Acceptability of Electronic Assemblies. For each standard, IPC-A-610F Amendment 1 and IPC J-STD-001F Amendment 1 represents a critical shift to deliver necessary updates to these already robust standards.
