You're correct. There is no criteria for no-lead, but there none for SnPb, either. Solder joint strength in pull/shear will vary with lead geometry, solder volume, lead metal/metallization, the way the test is done.

Hallo I am going to prepare our SMT and THT production to meet ESD protection. Could you please point some information theoretical and practical about ESD. Any web site, documentations which is important (standards-IPC), really worth books will

Recommend to check http://leadfree.ipc.org I agreed the lead free is a must for environmental and human health. Not sure how soon they can found out another harmful material

Jedec J-STD-033A for components. For the Fab and assy, you can check IPC-PE-740, Para. 1.5.4

IPC-FA-251 recommends 121*C for 30-60 minutes for 1 and 2 flex layer circuits. A rigid flex can take easily an hour per layer depending on the construction.

Is there IPC Standards that I could use with the following evaluation: a) Solder Paste Printing Performance b) Solder Paste Wetability What standards do you use or criteria when you evaluate solder paste with the above performance? thanks and r
IPC is the trade association for the printed wiring board and electronics assembly industries.
