Where do you get Kapton tape? I'd like to use some to hold components on the bottom of PCBs while reflowing the tops, just in case, but it's really pricey at Digikey & Mouser.

Try the makerbot suppliers.

They have this up to 12" wide and will often supply cut lengths.

Kapton has never been that cheap but i found makerbot much cheaper than RS.

Amazon is good enough, and free shipping with Amazon Prime account. I'm only after 1/2" and 1" to make sure SMD parts don't fall off boards that in that range of width.

Worse part is, I have twice bought small rolls at my "local" supplier (45 minute drive away) and we can't find it. Will likely show up as soon as Buy is pressed at the Amazon site ...

I did not look at larry's links, the amazon prices are probably the best i have ever seen.

Oh yes done exactly the same.

I use kapton for coils occasionally, new roll every time.

Have you ever tried SMT glue ?
I find it useful to prevent 'soldiering' with small resistors also takes away the double sided problem.
I have found that unlike solder it can have a shelf life of 5 years despite the stated 6 months.
Downside is the extra stencil.

Trying to get away from that since the '4050 needs soldering too. Apply past to the board, plunk down three parts, stick it in the oven. Done. Way faster than 56 solder joints by hand.
Dude, knife tip. I've done two posts about it in this thread, the more recent one should only be a couple pages back. It is seriously amazing, way better than a chisel tip.

Flux up your pins, feed a blob of solder onto the side of the knife, then just drag it down the line, keeping the blob fed as you go. You could probably do the 40 pin socket for a Bobduino in under a minute.

Soldiering? I am guessing you mean what I've always heard called Tombstoning?

Just had to bump my favorite thread back to the top.

So I might have to convert a little bit to the Bent Tip cult religion team...look, it just works well, OK?



I bought a soldering kit for my little sister to assemble, and she had a much easier time using the bent tip than either a chisel or knife tip. I still haven't used it myself (haven't had to solder anything recently), but there's at least some good newbie potential in it.

What kit? A theremin, and I didn't tell her what it was.  :D  I really wish I had thought to record her reaction when she reached out to touch it for the first time after I plugged in the battery.

Hi Larry,

I started THIS on http://ArduinoInfo.Info

May I add yours??

Anyone else??


Terry - I have seen a wiki site you have started and read an excellent article on there about controlling AC power with power FET's.  Would you mind if I dropped you an email?

I recently upgraded an iPad app that I use everyday (~$10.00 for the upgrade).
I use 'PDF Expert' for all my PDF reference materials: data sheets, books, articles, equipment manuals  etc.
PDFs, like the 650 page Amtel328 data sheet, can be: searched, bookmarked, annotated, edited and sent to other apps or printers.
The new upgrade allows you to:
- edit existing text - font/color/content/size/position
- add/move/resize images
- redact text
- link text to other page or WEB references.  
Of course, you can still annotate: draw/highlight/add comments/add text/add signatures/add and delete sheets/add stamps.
I always sync my PDF documents to offsite storage for a backup.

I got rid of 300 pounds of data books from my shelves.

Can't live without it!

I just received some 1284 Logger and MegaDIP boards from Crossroads.

If you ever need more I/O and more hardware serial ports these boards are for you.
Here is a MegaDIP mounted on a second story breadboard assembly.
Thanks Bob.

Looks like the beginnings of a serious project. What are you building with it?
