There is a huge inductor on the PCB so it looks like
there is a DC/DC converter on board. Can you read
the chip number of the chips that are directly under
this inductor on the other side of the PCB?
I'll tear it down again soon and add a few more detailed pictures

If anyone wants anymore details, let me know here! I'll update the OP with some additional details later.
How many years of warranty does Halong provide for these units?
6 months from the point of shipment - more information on the terms of sale page
hereYoshi did confirm it was Samsung and 10nm! More details this
tweetHalong is also the only miner manufacturer I've seen take this many payments options. In addition to the standard Wires/BTC options, they take BCH, LTC, ETH, XMR, DCR, USDT! Great to see a manufacturer accept the currency they sell miners on. A good thing!
