    The best method to remove the TO-220 package parts from the board is to first take your solder wick and set it aside until the part is out and use for cleanup. Next get a pair of hemostats. Clamp that to to tab and turn the board upside down hanging the hemostat over the table. Apply solder and heat. Eventually the weight of the hemostat will pull the TRIAC out once the solder becomes liquid and leave the runners and through holes in tack. Now use the solder wick to clean up the holes. Learned that trick over 30yrs ago and have never damaged a board since. It works for most leaded components. If you are industrious you can even place a narrow strip of thin metal under dip packages and clamp the ends with the hemostats and pull out 16 and 20 pin dips also.

    All other SMD work I prefer a hotplate. Works like a champ. Though you have only about two minutes or so to get the part on or off the board , then off the hot plate before you start to cook the board. I have very good success with 80 and 100 pin 1mm pitch BGA parts using a hot plate. Even fine pitch BGA parts can be done with a hot plate.

    Hi guys, newbie here. Just getting ready to try soldering my first boards. I've never done this type of soldering before but I have soldered pipes, I guess it's kind of the same principal. Lol

    Here's my question...I went down to radio shack to pick up some solder. I saw at the beginning of this thread you were using 63/37. They don't carry that, I picked up a spool of 60/40 rosin-core solder. Is this okay?

    Should be fine. You don't want Lead-Free, it's much harder to work with.

    Also, if you haven't soldered before, go to Radio Shack and buy a Perf Board and a thing of cheap parts. Use this to practice soldering. It's a great way to practice

    Yes, 60/40 is just fine.... 63/37 is just better.

    Thanks for the input gentlemen. I figured I would start with the SSRez's before attempting the 64xc. I did order extra of everything from Mouser so I would have spares due to rookie status.

    For a beginner, I certainly recommend soldering one whole board first. So complete a single SSR and review. Not a whole lot to mess up, but make sure you have sockets, LED and triacs oriented correctly.

    Unfortunately I didn't come across the thread discussing the new triacs before I ordered my parts. Mouser didn't have them (the "old" ones) so I ordered them from a company called digi-key. I did see from your posts you haven't had any issues. Hopefully mine will work fine too. Now to figure out how to connect these to my computer.

    I've done a fair share of soldering and desoldering on PCB boards. I find a solder sucker tool is a must have. I don't know if that is the correct term for it, but thats exactly what it does to hot solder. Sucks it right off the joint. And no mess like when using a braid. My Opinion.

    How well does this "no clean" solder work?

    http://www.circuitspecialists.com/4865-227g.html

    Is there any difference between no-clean and traditional rosin-core solder? It says none corrosive, so how does it clean the impurities and oxidation off he parts being soldered?

    IMHO, I actually like this better than my Kester44. I use the MG for fine work and Kester for larger fills. I think the MG flux splatters less and leaves less flux on the board.
