My soak at 150C - 180C for approx. 85sec to 100sec. I believe this is sufficient. I can't change my paste because customer wants to use SnPb paste with SAC solder balls. They claimed that they have sucessful result with other CM. I need to know if

The classic dilemma, cost vs. performance. In typical applications, Sn whisker growth is not an issue. It only seems to occur under extreme use (high stress, low temperature)conditions. Until this issue is fully addressed, Pd seems to be the favor

Good morning all. We are able to offer some insight into the problem and offer a recommended reflow profile to solve this issue, but it really depends on the solder paste that you use, as different manufacturers use different boiling point solvents.

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

Is anyone reworking BGA parts with an rf shield on top of the package? Any problems getting it off the board? I am running into an issue in that the shield comes off but the part remains on the board - not because solder has not reached melting but

The thermal recipe you use is dependant primarily on the solder paste that you choose.

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

Hi to all, I'm facing a soldering problem with one of my series of Product, since we were using a two different kind of PCB 1.GE(Glass Epoxy)2.PP(paper phenoline) in later PCB if i will use the same profile of the GE then it will get backed more & i

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.

Hello, this is my first post in this forum, but sometimes I visit it to get some news. Now we have an issue and I need your advice. Few months ago we were awarded with a project that use PTH components. We solder these components on Wave soldering
