RoboGuts™ S.T.E.A.M. Education Program

Hi, 

Yes, I ordered a bunch of soldering tips for the new 40W soldering pen (I was using a 30W pen, but it choked on soldering connector pins in the large ground plane on the RoboGuts™ circuit boards.  

I should be able to keep up with sales with this first batch of boards ... and hope I can get the next batch soldered in a wave solder machine.  

Hi,  In the process of using the new lead free solder so that the RoboGuts™ circuit boards are 100% RoHS compliant I found out that the soldering pen tips wear out about 100x faster than when using lead.  

I've gone though trying several different soldering pens and after a little research online I find that it's the reactions during the soldering that cause the iron on the tips to move into the soldering joint.
