Using a vapor degreaser with a solvent such as Vertrel, Novec, Techspray 1655, Solstice, etc. may work for you but solvents can attack certain plastics. Should be fine for SMT though. This is assuming you are using a no-clean (RMA) type flux, not wat

The recommended bake temperature for components in Tape and Reel is 40C. If you use a bake temperature higher than that, the cover tape and other elements of the packaging will degrade to the point that it becomes impossible to reliably use an automa

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?

At this point, I do not plan to back-fill with nitrogen. I have confirmed that vacuum baking, with the temperature set to 40°C, will result in the chamber %RH being less than 5%.

IPC-1601 covers PWB bake-out, methods for determining optimum bake time and temperature, caveats for certain PWB plating finishes, etc. IPC-1601 is to bare boards as J-STD-033 is to components

Does anyone know about low pressure/low temperature ovens used for baking of moisture senstive components? Thanks

Hi Steven, The 24 hrs bake is an overkill according with various J-STDs. Assuming a bake temperature over the 100 Celsius degrees. There are several factors to be considered before deciding the best methodology to wash misprinted board. However,

Daniel: In response to your questions: * Moisture level (wt%) that may cause delamination in PCB�s. - Certainly, it depends, but 100% moisture will not cause delamination of a PCB. [Now, heating that water is another question, isn�t it? ;-)] *

Hi, "Baker with controlled humidity 5%" is actually dry cabinet. Using of dry cabinets i.e. ambient temperature baking is preferred. Vacuum will always be better. If you are going to use vacuum chamber, that will be the best method in my opinion.
