Does anyone know if the IPC 610 standard call for baking bare boards (PWB) prior assembly? Note: I am talking about bare boars only and NOT plastic packages components, Regards. Eyal Green

What is a typical time/temp baking cycle for an assembly prior to BGA rework? This bake is intended to prohibit PCB or nearby component damage as well as protect the component being removed for reball. A 24 hr bake at 125C would be great, but often

Praveen, Once you find out the MS level of your components, you will need to track the exposure time from when the parts are initially removed from their dry bags, through test, programming, taping, and during subsequent dry storage and use of thes

Some additional comments from a paper may be of interest. Baking Printed Circuit Boards - Why and How Baking printed boards prior to conventional and surface mount assembly should not be necessary. Often boards are baked for historical reasons; in

Randy, are you baking initially for surface mount? These boards I'm talking about are just thru hole, so there would not be any bake between baking for part marking and wave solder.

We have always baked our assembled boards prior to wave solder, but have recently learned that there are some companies out there who don't. I checked with one of my supervisors, and he said that baking is recommended but not required. I'm wonderin

Greetings all you knowledgable SMT persons! 1. Typically, for multi-layer (6-8 layers), FR4, SMT boards stored in an air conditioned environment at about 50+/- 10% RH, how many months (or years) would you allow to pass before you would recommend bak

No parts or boards are baked unless they are moisture sensitive and were left out too long and that is for reflow only. In your case there should be no reason to bake becouse the boards should be vacuum packed as they come in as well as any moisture

Baking boards in a nonvalue added activity. Quit doing it!!! As a routine production activity, it is either: * Totally unnecessary ... OR * Band-aid to cover for problems in fabrication, purchasing, or storage methods. Search the fine SMTnet Archi

We do not bake any of our boards prior to wave solder. If we did we would have one heck of a large oven. I would assume you are concerned about moisture sensitive components. In most cases your top side parts should only get to 80 degrees centigarde
