5K has three BGA(Ball Grid Array) IC parts; QCC5124, and two ES9128p.
To enhance the PCB reliability and durability, we did the epoxy underfills on those sensitive BGA parts, although having additional cost increase. Those parts are bonded twice with soldering and epoxy underfills.

Following up on Joao’s question above. All the PCB photos show ES9218… was there a change in design since the photos were taken?
ES9128p??? Could you decide what chip it has? In one page it´s the 8218p, in other 9219c and now 9128p!
