[Blabber] Lots of soldering, tips and tricks?

Four suggestions:

1) Work faster ;-)

2) Send it to China. There are shops that will do it for not that much money.

3) Based on that picture, you might be able to build a jig easily. I'm picturing a block of wood or metal that:

- has a channel or something to fit the LED strip, maybe with an easy to use clamp; maybe just a wood surface, and two pieces of dowel nailed and glued down where the LED strip would slide into.

- some kind of clamp for the LED strip, possibly just a heavy block

- has channels or a set of pins or nails to hold down the cable. As a simple solution, I would clamp the wire a few centimeters to the left in that photo, and 5 pins so each wire slides into a specific position.

4) Buy a box of donuts, come into Hack Manhattan on an open night, and recruit people to form an assembly line for you.

What is your exact soldering process? I would probably do this:

1. Apply a decent amount of solder to each of the 4 contacts on the strip. Maybe do this first for a big batch of strips, it'll be faster that way.

2. Twist each of the 4 wires, apply flux, apply a little bit of solder, then a little extra flux. Perhaps one of those cans of flux that you can dip the wire end into.

3. Heat up the previously applied solder blobs and move each fluxed wire into the heated blob.
