When baking parts at 90C that require 15 hours bake time with parts that require 25 hours bake time, is it acceptable to open the oven and remove the former (15 hours) parts and then continue the 25 hours cycle for the remainder of the parts in the o

Thank you for the response, yes, the oven is vented. I guess I am concerned for parts with a thinner package body, so I wasn't wanting to leave them in for too long past the recommended bake times.

It won’t hurt’em if under 96 hrs.

Very good. Thanks.

Briefly opening the door probably won’t affect anything significantly. If in doubt, add an extra hour to the bake time. A better approach might be to keep both parts in the oven for 25 hours. You have up to 96 hours before oxidation becomes an issue.

Does anybody have any reliable alternatives to device bake out for plastic bodied components. We do not use a whole package at time and therefore have to oven bake the balance before we can use them. I have come accross dry nitrogen storage chambers

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

Dave highlighted all the elements that must be considered to determine the optimal temperature and duration for a pre-rework PCBA bake process. As far as the component is concerned, it really depends if you care about not damaging the package for r
