WebEpoxy is mostly used in flip chip assemblies to provide physical support for the chip and solder bonds. Solder bonds are susceptible to failure for a number of reasons. Physical shock, of particular concern in frequently dropped handheld devices, can easily cause damage to delicate solder connections. Another major concern is thermal expansion ... WebMar 25, 2024 · The investigated LED module consists of four blue flip-chip LEDs, electrically connected in series by SnAgCu (SAC305) solder joints on the copper electrodes of a printed circuit board (PCB). Here, the LED module has no underfill. The PCB was mounted on a liquid-cooled heat-sink via thermal interface material (TIM).
