• Maximum recommended board warp – 7 mils/inch*.
• Preferred maximum board warp - 5 mils/inch*.
Note: The recommended board warp is also based on the assembly process stencil thickness

(Sufficient for surface finishes that have less than
.001” thickness variation such as OSP, ENIG,
Immersion Tin and Silver.)
(May be required if using a HASL surface finish)
