Thermal characteristics

1/ Performed as either characterization or as part of qualification.
2/ The manufacturer shall define a "preconditioning" procedure that simulates board assembly of plastic surface mount
devices. This procedure should include moisture intake and reflow simulation. Exposure to soldering fluxes (possible
source of corrosiveness) and to board cleaning agents is also recommended for preconditioning the devices.
3/ Five hundred hours of highly accelerated stress testing (HAST) is preferred but the qualifying activity shall consider the
manufacturers overall processing and testing to evaluate this requirement. The actual HAST hours or alternate testing
shall be included in the QM plan.
4/ ESD classification level is as defined within test method 3015.
