Sheldon, Tip life is directly related to temperature, IRON plating thickness on the tip, Alloy composition used and operator technique. High tin contents in lead free alloys attach the tips. Poor wetting and higher melting temperatures cause us

I am curious if everyone else is seeing the same dramatically reduced tip life with lead-free that I am? We have purchased new irones with controlled temperatures up to 800F. We are doing more hand soldering on our lead-free at the present while wait

You are exactly right, tip life is greatly reduced with the pbfree alloys. Some mafgrs are using an extra thick plating to reduce this. Next directive will be to determine what to do with all the tips now.

I also heard that fluxes are more agressive in lead free alloys. Try maybe to clean your tip more often ?!?!?

Sheldon, Try using SN100C wire solder. It seems to extend the life of the tips plus solder joints look much better. We use both, clean and No-clean. We had the same problem while using SAC305... Thanks, George

Hello to everybody in this forum, I would like to know any information that you kindly may have about the following subject: We very often do manual soldering assembly of immersion tin finished PCBs. Since thiourea is used in the formulation of the

Just come back from Nepcon (electronics show on an obscure little island on the other side of the pond) and had a good chance to look & play with a whole bunch of solder wire. Koki do one that is aprox. 99/0.7/0.3 with 0.03 Cobolt in. They claim th

Hi Steve, Although your opinion is valid, calling something from a respected Japanese manufacturer crap is a little harsh. I have seen many people solder very well with all sorts of leadfree alloys - not producing crap. I've already had a play wit

Since when is Hakko putting more plating on their tips? I was told that there was no change to their tips, it was the same tip for Pb or Pbfree. Prior to first use, all Hakko tips are Pbfree. We have been seeing those tips degrade quicker with Pbf

Hi,my master How to iron out such soldering bridge with below conditions: 1.The component(Harness)lead pitch is 2.0mm,the lead length is 3.2mm. 2.PCB width is 1.6mm.Pad size is 1.65mm.Its a single copper PCB 3.using spraying fluxer and no-clean fl
