Rework of New High-Speed Press-Fit Connectors
New high-speed press-fit connectors have several hundreds of thin, short and weak pins that are prone to damage. Small variations in via hole dimensions or hole plating thickness affect the connections: if the holes are too small, the pins may be bent or permanently deformed; if the holes are too large, they will not form gas-tight connections. This study, recently named Best Technical Paper at IPC Apex Expo 2017, details how rework of these new connectors affects connection strengths, hole wall deformations and plating cracks.
