content: If you are considering using a really low end Chinese manufacturing services, please don't:The worst thing is, the loud high pitched guy seems really happy about those solder joints...I know not all Chinese hand-manufacturing services are not this bad, but BE AWARE.But for you cheap people out there, here's how hand soldering is done! Take some notes ladies and gentlemen:All credit goes to the content uploader, including the Chinese guy.

content: Soldering iron is a bit worn but should still be usable...Hmm... well, I don't normally use that much solder to tack the corners, but.........Wait, what's she doing? Is she tipping the solder off?...Yes, she is tipping the solder off.

The man looks like he might be Chinese by ethnicity but the woman doesn't look Chinese at all. They must be from one of the south eastern Asian countries, either the Philippines, Thailand, Malaysia, Indonesia, or Singapore. Not saying workers in China aren't using the same "technique" though...LOL!

content: Yes the new flood and dump technique.She wasted enough solder to drag solder all the devices on the bench.Btw its a Hakko 936 or copy. Handle looks just like a 907 and holder exactly like my 936.

content: I think she did pretty good all things considered. Interesting technique, what you waste in solder you make up for by using no solder wick.

content: It's definitely not Chinese. I once visited an assembly house in the Phillipines who told us that "Oh. We use solder tipping. Reduces amount of wick" when I asked about their process. Granted, they died a few months afterwards.

content: Quote from: rdl on February 12, 2014, 01:27:51 amPretty good except that she probably overheated the chip, lifted the pads a little, oxidized everything, didn't clean the board, produced a poor joint from the vibration, wasted solder and was proud of it all. You don't need wick or expensive equipment if you do it properly. Also over three minutes? I can do it faster and much better.

content: Go to 0:40 in the second video in the first post and see how fast he solders that chip that's similar in size to that xilinx.imho the first video is just... I don't know, it's like they try to win a contest at how cheap and time consuming they could solder something.They could have also dipped the board in flux, put some solder on iron, drag over pads, put chip on top, move already heated hot air gun over the pads. Half the time, close to perfect solder.

content: Quote from: mojo-chan on February 12, 2014, 01:20:59 pmWell I don't know much about other manufacturing but I've worked in a company where a great deal of hand soldering is done, on runs under about 5 boards they typically hand soldered as the time to set up the PnP is longer than the hand soldering time. Except if there's a BGA or high density QFN, prototypes and low quantity runs all hand done.I have some boards here and you couldn't tell the difference between the hand soldered and machine soldered ones. (And that doesn't mean the reflow is bad!)

Plus, this gives you a bunch of samples before the initial run is started.
