While trying to sell me a low temperature baking system for SMDs the salesman mentioned that the 125C for 24hr bake had been known to cause co-planarity defects. I thought I'd ask some experts. Any help guys?

The answer is yes, it is possibly a moisture-related problem. You can confirm this by baking your parts at 125C for 48 hours (ref. J-STD-033A, table 4-1). For more technical background on this issue I recommend you read the following paper : Impac

DaveF, Our customer requirement is to comply with IPC-STD-001 but the J std doesn't specify the bake out temperature for populated boards and the moisture absortion rate. Right now we are baking the populated PWAs after aqueous wash at 80C at 18-48

Q1. Can I do this myself on site? A1. Sure. Most companies demoisturate their components in-house. Q2. Can we use our Vitronics Soltec XPM820 Reflow Oven? A2. You can. Most of us would be using an oven like that in our product processing. If you look

There are no requirements acceptance criteria for baking of board assemblies. What are your customer requirements? The common reasons people choose to bake PCB are to prevent: * Delamination of multilayer boards * Measles, particularly on double si

I guess the first thing to look at is the temperature. We had to heat more for QFP256 on sample boards and we saw discoloration on some small parts. Just try to sense around when profiling to see what's there.
