Hi Pavel, Real Chunks, Thanks for your valuable inputs..Selecting the correct location for board profiling is critical in determining the solder joint quality. Am I right to say TC wire attachment locations priority should be as below: (1) Thermal

I don't think thay offer that specific alloy, but if you check with Kester, Alpha, and Indium; they might be able to suggest a supplier or an alternate product thaat is quite similar.

We got a similar alloy Sn05Pb93.5Ag1.5, of Alpha Vaculoy bars. It is not the eutectic alloy you were looking for but it is close. This alloy and similar high temperature alloys are used in downhole electronics and so a supplier in the Houston area

Quick production (no "pasty" phase) > High joint surface quality > Good flux action > No discolored, corrosive, or substantive residue of any kind > Lead-free is not a concern ;o) Any input/ideas are appreciated. Thanks!

Hi, We are currently having issues with hand soldering High melting point solder wire. Can anyone give a few tips. We are Preheating boards to 120 deg C and using soldering irons @ 410 deg C. The quality is ok but the ts taking 20-30 seconds to c

No, the thicker plating and need for very high quality drilling and plating is DUE to the higher copper dissolution rate and higher contact time. As to the Sn100C material, their claims seem to confirm a "lower" copper dissolution rate, but so does A

One of our PCB for high reliability application is having 2 BGAs(11X11, ADV 204), The pitch is 1 mm. We decided to wire the BGAs first using re-flow soldering and the rest of the components by hand soldering. Since the PCBs are for high reliability a

Robot soldering has never really worked well and if you are looking for any volume or repeatability, you may be disappointed! Even though you are using a robot, you are still soldering with an iron and wire solder. This process cant guaranty the be

Thank you- my point exactly and it starts in SMT- operators pulling the wrong paste from the fridge, touch up using the wrong solder wire, etc. My solution- GET THE LEAD OUT!!!!! I'm a CM- high mix, low to medium volumes. No steady all day every day
