Hi, The bath is titanium coated, and the machine is only 2 years old, and was designed for lead free, so we know we don't need to change anything. The reason the supplier gave for suggesting the bath change is "other companies are doing it" and it'

we've received an inquiry if lead free solder for solder dips or surface mounting (cream solder) is available on a technical scale

Hi, We are running lead free at wave solder now and the spray flux system is down. If we are going to able the flux manually, what problem will we be facing with the excess flux able. Appreciate for the advise.

With the added temperature peak associated to Lead free reflow is anyone seeing or concerned about the increased vapor pressure that may result from moisture entrapment in moisture sensitive components?

Anyone know any international standard (e.g. IPC, JIS) for the SAC lead free solder strength ? If no, any industrial / company standard for it ? Besides, any mathematical model which can help to calculate it.... express in "Force / area "

It's possible your supplier has not thought through the results of their conversion to lead-free throughly. We'd expect something like: Reflow Parameters||Pb Assy||Pb Free Peak Temp.||235�C �5�C||255�C �5�C Time Within 5�C Peak Temp.||20 to 40 sec.|

The solder paste formulation is different 63/37 is a tin lead alloy so t here is one difference from a lead free. Yes you can get no clean lead free products but if you compare the amount of visible residues they will be normally higher. So far most

IPC-A-610D Section 5, shows a variety of photographs of: * Good lead-free solder connections * Lead-free soldering anomalies Hot Tear / Shrink Hole is one such anomaly. This shrinkage effect appears primarily on wave-soldered joints, but can also

What volume of boards are you putting through. 1Kg per hour does sound very high but then again it does depend on volume Using an antioxidant is a must with Lead Free some alloys have additions in them to start with but those drop out with use so th

Hi all, What are some of the must do, cannot go without changes to our process and equipment before we adopt a lead free process? Would we have to completely change out our ovens? I thought I read that using old ovens was a no-no. I just began
