Shenzhen – Phone recycling -4-

with 5 comments

Although the components that are sold here don’t have the best reputation, there are a number of quality control methods used to make sure everything is still in working order. One of them is an optical check for any obvious damage.


More interesting are test setups that use rewired versions of the devices that the chips original came from.


These boxes are made-to-order for specific phones and specific parts. The shop that sells them is one of several tool suppliers in the building. There are others selling soldering irons, heat guns and books with circuit board schematics.

Finally the most valuable chips get reprogrammed or flashed and packaged into trays and tape reels (I’ve seen them do it!) that can be fed into the pick-and-place robots used to build new devices.




The next post will be dedicated to the other activities in this building, such as the (partial) fabrication of Shanzai phones.

  3. To be very honest, i’m buying regularly such recycled parts. It started some time ago as i had to buy some NAND memories. My supplier was not able to deliver more than one tray (11 NANDs from a single tray with bad sectors …) so i asked chinese supplier. He told me “i can supply requested amount in time but they are recycled parts and 100% ok”. No risk, no fun – due project pressuere i did it. It was really funny, from 8 full trays only 2 !!! NANDs with bad sectors. In principle such bad sector is nothing really bad (for most projects), but it was amazing to see that recycled parts were better that new parts from known big supplier.

    Thanks for this article, now i know how hard is for them to get these parts!
