Package and Handling Information
Because of its sensitivity to moisture absorption, this device
package is baked and vacuum-packed prior to shipment.
Instructions on the shipping container label must be followed
regarding exposure to moisture after the container seal is broken,
otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SKY77171 is capable of withstanding an MSL3/250 °C solder
reflow. Care must be taken when attaching this product, whether
it is done manually or in a production solder reflow environment. If
the part is attached in a reflow oven, the temperature ramp rate
should not exceed 3 °C per second; maximum temperature should
not exceed 250 °C. If the part is manually attached, precaution
should be taken to insure that the part is not subjected to
temperatures exceeding 250 °C for more than 10 seconds. For
Electrostatic Discharge Sensitivity
The SKY77171 is a Class 2 device. Figure 8 lists the Electrostatic
Discharge (ESD) immunity level for each non-ground pad of the
SKY77171 product. The numbers in Figure 8 specify the ESD
threshold level for each pad where the I-V curve between the pad
and ground starts to show degradation.
The ESD testing was performed in compliance with MIL-STD-883E
Method 3015.7 using the Human Body Model. If ESD damage
threshold magnitude is found to consistently exceed 2000 volts on
a given pad, this so is indicated. If ESD damage threshold below
2000 volts is measured for either polarity, numbers are indicated
that represent worst case values observed in product
characterization.
Various failure criteria can be utilized when performing ESD
testing. Many vendors employ relaxed ESD failure standards,
which fail devices only after “the pad fails the electrical
specification limits” or “the pad becomes completely
non-functional”. Skyworks employs most stringent criteria and
fails devices as soon as the pad begins to show any degradation
on a curve tracer.
To avoid ESD damage, both latent and visible, it is very important
that the product assembly and test areas follow the Class-1 ESD
handling precautions listed in Table 5.
