    I suppose if someone's reading this thread it's because they want to learn how it may be done. That said, holding your soldering iron against the piezo for a full minute will probably destroy it, unless you have a really low-powered iron... I'd take that advice with a grain of salt - though I do agree with scratching the surface with something sharp, that does help a lot.

    However, I've posted this elsewhere but I guess there's no harm in linking to it again, as it's a method I've been using for years with great results: the "no solder" approach. No soldering skills (or any skills at all for that matter) involved and your piezos will last much longer than if you solder the leads on.

    I love to build things myself but for the average DIY edrummer, aren't they better off buying something like goedrums prewired piezos? I'm very interested in learning any counterpoint to that notion.

    All I had to was this:

    1. Tin a nice amount of solder onto your wire (in my case the black wire)
    2. W/ flat head screwdriver or something like that scratch the brass off enough for a contact surface for the wire
    3. Hold your soldering iron on the scratched surface for a while to heat it up, like at least a minute
    4. Now quickly and carefully since its hot hold the wire with the solder on the scratched hot surface and press the iron down until it melts

    That's it! It seems that unless the brass surface is hot the solder can't bond with it and the sound quality is just fine, good luck!

    I know this is an old thread about soldering to piezo elements. But the information in it is bad and will most likely destroy your element. For soldering brass piezos it is simple and try and use as little heat as possible. The videos on youtube for this are adequate. For stainless steel piezos this is a different story.

    I purchased these stainless steel piezos here: piezos at ebay auction, good deal.

    If you read the instructions you need to pay attention to getting the chemical that will etch the stainless. The chemical used to etch stainless is PHOSPHORIC ACID which can be bought at a local hardware store. It is used to remove the oxide layer of the stainless. Without it you will overheat the element and most likely destroy it. I did not have this chemical on hand so I tried various things. Finally I realized I had PCB etchant solution on hand which is FERRIC CHLORIDE based. Once the chemical was applied for a short time in a very small amount I cleaned it off. The surface was very much a different color/finish after this. Then I soldered and it soldered as easily as it shows to solder the brass piezos on youtube videos.

    Soldering to the piezo material (white circle) is easy and does not take the chemical to prepare the surface. The piezo surface is easy to solder on either type, but do NOT apply heat for long or it will melt away the piezo material.

    Do NOT do as others have recommended and hold heat on the stainless portion for 3 seconds or more. This will not solder well, and it will damage the piezo element. The temperature used to make these is not that high and soldering iron heat can destroy them even if on the metal surface itself.

    Anyway, I don't do much with music. I am wiring some piezos up to fix some dance pads for my kids.

    omg now i figure out my roland td7 isnt stereo ....i make a diferent connection

    in acoustic pad... dual works in this way ......

    tip snare is tip/ sleeve .......

    ring is connection between ring and tip without sleeve ....

    i ve play with theese and im hope soo im right because the diferent sound is hear .

    but i dont understand THE BEATNIK ROLAND WIRING CONNECTION what roland module has he meaned

    any help will be gratefull or some other information about td 7 because i cannot find informations about this problem with this module

    I'll Quote Bruce for the answer to this one:

    Also I would say Use the Search Engine ..... But there is a better search engine..... If you use this search engine you can get some great results:

    For those that have never used that search engine, Bookmark it, Use it, Works Great! J

    OK, so I talked to the guy at the store and found a good method for soldering these babies.
    I am of course talking about the type of piezos shown in the pictures in the opening post.

    I can safely say that the metal on these these is NOT the same as on the ones mikejl46 solders in his video. That method would never work on these piezos.

    The problem is that the solder just doesn't stick to the metal like it normally would, and if you touch the soldering iron to the tin at any point, you can be absolutely sure that the tin will stick to the iron, and not the piezo. So part of the trick is to never ever touch the tin with the soldering iron directly, at all.

    Of course, this only applies to the metal rim - the silver on top of the ceramic is easy peasy.

    OK, so here is my guide:

    -Scratch up the point that you want to solder with a sanding block or something similar. This may help the tin stick a little better.

    -Solder the tip of the wire.

    -Fasten the piezo in some kind of metal clap - it will get very hot!

    -Press the hot iron on the bottom of the point where you want to solder, and hold the tin on the solder point.

    -When it starts to melt, make a bead the size you want.

    -Keep heating it for a little while, and then - very slowly - sink the tinned wire into the molten tin. If you go too fast at this stage, or don't heat the tin enough, you will just be rolling the tin bead around like quick silver. Very annoying.

    -Remove the iron and blow. Remember that the piezo is probably quite hot at this point, so unless you have always wanted a piezo imprint on your fingers, or just love all kinds of memorable experiences, give it a little time before you handle it.


    Violá and good luck/patience!

    I will definitely be looking for different piezos next time, as these are just too much hassle!

    Thanks jman, it might be the rosin thing, since I have no data on the solder... It was given to me in loose weight. It's great for soldering circuit boards, though.

    I called the electronics store today, but the guy didn't seem to know anything, and told me to call back tomorrow and speak with someone else. Why does he work there?

    So I tried soldering to the "bowling pin" and "the other ceramic part", and that actually works, so maybe one of those areas are actually connecting to the brass?
    It doesn't seem to give as much signal as I would like, though...

    Any thoughts?

    I have a pretty decent soldering station that will go up to 420C (790F), so that should be enough, no?
    Should be enough heat, but once you apply the solder leave your iron on it for several more seconds. It will eventually get hot enough and start to flow. It is very important that you either apply rosin first or get rosin core solder or it will never work!

    I use this soldering paste, it makes this kind of soldering a breeze.

    actually i dont know,
    i just use a cheap basic iron that i bought from radiashack

    The easiest and fastest way I have found is this. http://www.wireglue.us/

    It works just as well as solder without having to worry about ruining the piezo.
