The incorporation of low- standoff devices and the ability to completely remove water soluble organic residues is driving more assem- blers to consider a no-clean process. The risk assessment of water soluble versus no clean in these applications consistently favors no clean. The cost savings in decommissioning the wash process and equipment is another major reason for migrating to no-clean chemistries. Finally, as conformal coating continues to be the only accepted practice for tin whisker mitigation, along with the looming expiration of the RoHS exemption, we predict no-clean chemistries and the subsequent coating of the resulting residues will become increasingly prevalent over time.
