| | Has anyone out there tried to parylene coat plastic parts prior to soldering them to a pcb? I'm looking at several potential applications where fewer than 5% of my components on a pcb are plastic, yet from a reliability aspect (environmental cond

| We are currently using a 65/35 solder for our wave process but are considering switching to a 63/37 for a substantial cost savings. No one here seems to know why we everused a 65/35 formulation in the first place. | I understand 63/37 to be pretty
