Here's pics of all the damaged boards. It's pretty obvious the box was thrown around and even though it was intact you could tell the box wasn't nice and rigid. I'm pretty sure even though the boards were taped together and packaged in bubble wrap the adjacent boards heatsink would hit the capacitor/other components and did all the damage. I think one way around this is to either have all the boards in tiny individual boxes which would cost more to ship and up the cost. Another idea is to have the end consumer install the heatsinks themselves and tape all the boards together and put them in one box and all the heatsinks in another box. Then combine these 2 boxes in 1 bigger box to ship it. I'm sure on small orders the boards will arrive in much better condition because of the package being lighter.

Burnin I'm pretty sure I can fix most of these boards. I'm sure Mouser electronics would carry the parts and I get parts from them quickly as I've ordered parts in the past from them. I just need a bit of help finding the parts if you don't mind.

Most boards have broken part 1(choke coil?). Its a through hole so I can solder that no problem

One board has cracked part 2 (haven't powered it on yet, I may later today on a separate smaller psu).

Four boards have damaged capacitor part 3

One board has damaged part 4





Here are the damaged boards








You can see the capacitor pulled up part of the copper trace, but it may still function.
