RELIABILITY

Microchip qualification will include aging at various extreme temperatures, shock and vibration, temperature cycling, and

IR reflow simulation. The VC-714 family is capable of meeting the following qualification tests.

5.0

IR REFLOW

Devices are built using lead-free epoxy and can be subjected to standard lead-free IR reflow conditions shown in

Table 5-1. Contact pads are gold over nickel and lower maximum temperatures can also be used, such as 220°C.
