@tsys ,
I opened up my PBP today to take a closer look at the audio amp chips U19 and U20 (xa9108). Because I don't have a depth guage I wanted to look at the chip datasheet. I could not find the datasheet for these chips online, but I found one similar (ant8108) and confirmed their physical sizes are approximately the same. The datasheet of the similar component shows a max height of 1.75 mm.
I haven't ordered from JLC but their standard PCB thickness is 1.6 mm according to their website. So a potential issue is that the adapter board may not provide enough clearance to get the daughter board cleanly (parallel) over the audio amp chips.
