Suggested IR profile
The VC-710 is qualified to meet the JEDEC standard for Pb-Free assembly. The temperatures and time
intervals listed are based on the Pb-Free small body requirements and parameters are listed in the table below.
The contact pads are gold over nickel so lower IR reflow temperatures such as 220°C can be used (device is
backwards compatible with a lead solder assembly).
The VC-710 is hermetically sealed so an aqueous wash is not an issue.
