Weak Microvia Interface Open Forum at IPC APEX EXPO


Reading time ( words)

The IPC V-TSL-MVIA Weak Interface Microvia Failures Technology Solutions Subcommittee formed in 2018 to identify the need to identify the risks, causes, and mitigation of failures due to a weak interface between the plated copper at the bottom of a microvia and the underlying copper surface.

The subcommittee will hold an open forum during IPC APEX EXPO for industry to discuss this important topic and how industry can come together to address it. Attendees will be invited to share their own issues regarding the weak microvia interface and will learn how to participate on the subcommittee.

IPC Weak Microvia Interface Open Forum
Wednesday, January 30
10:15 AM to 12:00 PM
San Diego Convention Center
Room 11A

Preliminary Agenda

1. Background: History of the effort, scope of work, status and organization

2. Presentation: Current Understanding of the Problem/Mitigation Measures

3. Weak Microvia Interface Project Subteam Reports

• Data Collation and Mining on the Issue

• FMEA “Fishbone”

• Engineering Simulation

4. Next Steps and Goals

• Near term: Breakout teams

• Middle term:

o Knowns/Unknowns: Can any intermediate conclusions or improved mitigation techniques be communicated?

o Identify Testing Needed: Gaps and confirmation

• Long term: Prevention: Can it be accomplished through design, process enhancements, etc.?

5. Q&A Session and How to Get Involved

The IPC V-TSL-MVIA Weak Interface Microvia Failures Technology Solutions Subcommittee formed as a result of work done on IPC-WP-023. Order IPC-WP-023, IPC Technology Solutions White Paper on Performance-Based Printed Board OEM Acceptance Via Chain Continuity Reflow Test: The Hidden Reliability Threat – Weak Microvia Interface from the IPC bookstore.

Surface Treatment Enabling Low-Temperature Soldering to Aluminum

07/15/2019 | Divyakant Kadiwala, Averatek Corporation
An increasingly popular method to meet the need for lower cost circuitry is the use of aluminum on polyester (Al-PET) substrates. This material is gaining popularity and has found wide use in RFID tags, low-cost LED lighting, and other single-layer circuits. However, both aluminum and PET have their own constraints and require special processing to make finished circuits.

Failures and Reliability in Soldering

07/09/2019 | Michael Gouldsmith and Zen Lee, Thermaltronics
The definition of failure is "the lack of success in doing or achieving something, especially in relation to a particular activity." If the activity is concerning a soldering process, such a failure can have a downstream impact far beyond the actual solder joint. In this regard, it is first necessary to understand what constitutes a good solder joint because appearance is too often deemed a success.

Low-Temperature SMT Solder Evaluation

07/05/2019 | H. Osgood, D. Geiger, R. Pennings, C. Biederman, J. Jiang, and J. Bernal, Flex Inc.
Until recently, the use of Sn/Bi-based SMT solder materials has been investigated with negative consequences for high strain rate (drop-shock) applications; thus, these alloys have been avoided. Recent advances in alloy 'doping' have opened the door to revisit Sn/Bi alloys as a possible alternative to SAC-305 for many applications.
