Mat, Are you sure you should be using SnPb HASL boards if you are doing prep for lead free? If you aren't actually going to comply with RoHS then fire away. Nearly all of our assemblies are now ENIG and as any re-design comes up on a HASL board it is

Hello all, Can you tell me what standart is used for communication between machines in production line. I don't mean SMEMA. There is a standart for machine communication, they can communicate one with another. That is the way for example AOI says th

If there's no shear strength standard for solder joint, how will I define my pad width and length then. I have a 8.5 mils width and my component lead width is 8.66 mils based on manufacturer's minimum width specification. How will I identify that it

Can anyone guide me to what test do I need to be able to identify the strength of my fine pitch component solder joint? What value is available that I can use as a reference? Say 1.5 kg, 2.0 kg, 2.5 kg etc. I would like to have my fine pitch compone

I have been following this thread with a great interest. However, the rules or legislations that control RoHS standards is maybe questionable, but I can't see why people/companys have so hard to think about the "next generation"? The fact is: RoHS is

It's hard to say something is "better" than something else. How is the Essemtec a better machine? Is it faster & more accurate for less money? Is it easier to maintain yourself? Does it have a greater install base and more service personnel per

OK, granted, this is not exactly your hi-tech SMD production but pertains to lead-free so I'll post this anyway: Can anybody share their experiences on lead-free dip soldering of transformer terminals? I have not done any testing myself but have see
