Post Baked missed

January 16, 2013

Q. We have parts that our plater did not post bake properly (instead of 190 °C they did 190 °FF for 12 hours).
Do we have to scrap the parts or can we start the plating process over and bake properly or will the parts still contain the risk of hydrogen embrittlement?

A. Hi. They sound like history to me. But honestly, how can an experienced plater make such a silly mistake as to "bake" parts at lower than even boiling point?
