230°C max x 180 sec max x 1 time
Typical Operation Data
20 to 100 sec up to 215°C, 50 sec at 215°C,
(Vapor phase reflow)
then down to room temperature per 1 to 5°C / sec
Environmental Characteristics
Temperature Cycle
The specimen shall meet electrical characteristics after
tested 5 cycles of -55°C / 30 minutes and +125°C / 30 minutes
Hermetical
No bubbles appear in Flourinert (FC-43) at 125°C ±5°C for 5 minutes
Solvent Resistance
Marking will withstand immersion in
Isopropyl Alcohol or Trichloroethylene
Mechanical Characteristics
Free Drop
The specimen shall meet electrical characteristics after tested 3 times,
Free Drop testing on the hard wooden board from a height of 75 cm.
Vibration
The specimen shall meet electrical characteristics after tested
by the following conditions: 10-55Hz 1.5mm Amplitude,
55-2000 Hz 20 G's, 2 hours for each plane
Thermal Shock
After applied Thermal Shock of
245°C max x 10 sec max x 2 times, or 215°C max x 180 sec max,
the specimen shall meet electrical characteristics
Solderability
(EIAJ-RCX-0102/101 Condition 1a)
