No, there are no issues with mixed lead / no-lead post-reflow cleaning. No-lead is a little harder to clean so be sure you use the appropriate parameters and cleaning chemical. The only potential issue is if you mix up the boards after cleaning,

I have a customer that is wanting to use a low-temp solder paste such as SnBi for a lead free circuit, however they are specifying PET for the flex circuit. I have always used polyimide for SMT reflow due to the temperature limitations of polyester.

Pad cratering has become more prevalent with the switch to lead free solders and lead free compatible laminates. This mainly is due to the use of higher reflow temperature, stiffer Pb-free solder alloys, and the more brittle Pb-free compatible laminates. However, pad cratering is difficult to detect by monitoring electric resistance since pad cratering initiates before an electrical failure occurs. Several methods have been developed to evaluate laminate materials' resistance to pad cratering. Pad-solder level tests include ball shear, ball pull and pin pull. The detailed methods for ball shear, ball pull, and pin pull testing are documented in an industry standard IPC-9708. Bansal, et al. proposed to use acoustic emission (AE) sensors to detect pad cratering during four-point bend test. Currently there is an industry-working group working on test guidelines for acoustic emission measurement during mechanical testing.

Manganese can be an optimal alloying addition in lead-free SAC (SnAgCu) solder alloys because of its low price and harmless nature. In this research, the mechanical properties of the novel SAC0307 (Sn/Ag0.3/Cu0.7) alloyed with 0.7 wt.% Mn (designated as SAC0307-Mn07) and those of the traditionally used SAC305 (Sn96.5/Ag3/Cu0.5) solder alloys were investigated by analyzing the shear force and Vickers hardness of reflowed solder balls. During the preparation of the reflowed solder balls, different cooling rates were used in the range from 2.7 K/s to 14.7 K/s.

. Nitrogen also may reduce discoloration caused by the higher temperatures and longer reflow times for lead-free pastes. Additionally, because lead-free joints tend to be duller than tin/lead joints, nitrogen can improve their appearance
