Dan, We, do alot of double reflow. Your right we typically see alot of the standards components, SOT's, SOIC's, Chip stuff. The largest we do with out adding epoxy is some 32pin PLCC's. We have several assemblies were were doing PLCC44's, Sockets

Reflow Soldering Processes and Troubleshooting: SMT, BGA, CSP and Flip Chip Technologies

Technical Library | 2021-01-03 19:24:52.0

Reflow soldering is the primary method for interconnecting surface mount technology (SMT) applications. Successful implementation of this process depends on whether a low defect rate can be achieved. In general, defects often can be attributed to causes rooted in all three aspects, including materials, processes, and designs. Troubleshooting of reflow soldering requires identification and elimination of root causes. Where correcting these causes may be beyond the reach of manufacturers, further optimizing the other relevant factors becomes the next best option in order to minimize the defect rate.

Investigation and Development of Tin-Lead and Lead-Free Solder Pastes to Reduce the Head-In-Pillow Component Soldering Defect.

Technical Library | 2014-03-06 19:04:07.0

Over the last few years, there has been an increase in the rate of Head-in-Pillow component soldering defects which interrupts the merger of the BGA/CSP component solder spheres with the molten solder paste during reflow. The issue has occurred across a broad segment of industries including consumer, telecom and military. There are many reasons for this issue such as warpage issues of the component or board, ball co-planarity issues for BGA/CSP components and non-wetting of the component based on contamination or excessive oxidation of the component coating. The issue has been found to occur not only on lead-free soldered assemblies where the increased soldering temperatures may give rise to increase component/board warpage but also on tin-lead soldered assemblies.
