Trying to understand the impact of iron contamination above IPC recommendations (0.02%) on selective solder joints. Brittleness and discolouration are known but are there other factors that should be accounted for?

I am partial to Weller for the small rework irons. I use both the WSL with WMP (current model) and some older EC1302 irons with their power supply (I forget the model, but the one with analog setting knob and digital temp readout). I actually prefe

I have looked at the JBC irons several months ago, and we will be getting a few of them for the people that do rework all day long, but for the general user around here all they are doing is touch-up and 500 bucks for an Iron for 50 people is a littl

How do you know that "approx 450�C" is "too high"? As a side, the temperature on the temperature sensor is: * Inaccurate. * Not the temperature at the solder. Listen, operators are smart people. They have figured-out that they can solder faster wi

I agree with everything stated thus far. However, what soldering iron are you using. You may be able to solder the pin with an iron that delivers continuous heat and if there is room utilize a large tip as a heat reservoir. What happens is that the i

The methods Terry mentioned are good, but our operators are too impatient. Here's how they do site prep, after removing the BGA: * Use a soldering iron to melt the solder at the base of the ball. * Flick the ball[s] from the pad[s] with the solderin

You didn't explain exactly how you are reworking the BGA and at what point the pad comes off. Assuming it's from an iron... The biggest cause of lifted pads is too much heat. Whether it be the iron temp or the amount of time the iron is on the pad

At a previous job we had a kit to splice the belts. It was a clamping and squeeze device and a soldering iron with a flat blade. You would cut the ends for a suare edge, put the belt in the clamp unit with a small gap. Use the iron to melt both en

The temp your iron is set at is somewhat irrelevant, it is the temp at the tip right? We use metcals and have 700 deg tips for leadfree. As you may know Metcal temp is at the tip and not a heating element seperate from the tip like many irons are.

We use JBC here. I like the response time of the iron tip. When soldering, the tip temperature does not drop as much as the Weller's we used to use. I like the ease of changing tip sizes. I dislike the cost of replacement elements. The tip and
