Hello,
We intend to obtain CE compliance for our products which means we must be compliant with RoHS. RoHS requires lead-free soldering. I googled about lead-free soldering but I still have some questions for experienced in this field people:
1. Should we change somehow footprints on existing PCBs for lead-free soldering or changes relate with stencil's apertures only?
2. Does anyone know about decreasing of reliability in the long term related with using of lead-free technology? I mean, if device successfuly passed all manufacturing tests, can it go out of order more likely in relation with using lead-free soldering because of aging of solder or something like that? Are there any ways to decrease such consequences?
3. Can we use lead-free PCBs with non-RoHS components?
4. Are there any non-RoHs componets that can't deal with thermal profiles for lead-free soldering? Should I check every component for compliance with lead-free soldering thermal profile?
5. Are there any other unexpected problems (so "called troubles in paradise" or "hidden rocks") connected with transition on RoHS technology? How avoid them?
