Yano, at lot this discussion is kinda school boy theory. Other issues are: * Soldering time * Corrosion [did we say that already?] * Safety [ie, personnel, plant, environment] * Cost of ownership

Hi Everyone, I am just curious, is there a guidline that people follow for choosing their lead-free solder paste? In other words, how do people know whether they should use Indium alloy, or Castin (Sn/Ag/Cu), or whatever else? Thanks

what is the best solder paste type(RA,RMA,R,WS,...) for removing oxidation from the pins of our parts.

One of our quality engineers established a procedure to use Tarn-X to clean terminals prior to soldering.

Wire wheel works too. Pre tin the part. Hand solder after reflow. Or order good parts. I prefer the last one. Hows that for an answer?

The temp is not an issue with selective soldering as the SN100C can be used at the same temp we used for tin lead. 260C. Some are using a higher temp, we did not notice any difference in the results with a higher temp. Most people run thier waves a

On average there are about 3 parts per board that get hand placed (x24 is 72 parts per panel). One of these parts is a big 1W resistor that cannot fit on our axial machine. We also have a Zener Diode that needs to be hand placed because its leads are

From what I see, you have a couple of options... 1. Hand solder the secondary side LED's. This is only a good option if you're going to be at low-ish volumes. Higher volumes tend to necessitate more automation to reduce production costs. However

Hey guys, My company is currently looking into developing a SMT line. I have an interesting perspective on this due to the fact that I worked a SMT line for quite a few years as an equipment operator. Now I am an engineer and at a different company

We have two selective wave machines that run all day every day. We're pretty high mix. Almost all products don't require preheat but it is nice to have in case you need it on something dense. Good reliable flux sprayer is important. Software that
