REFLOW MOUNTING CONDITIONS (RECOMMENDED)
Perform mounting using the temperature profile shown below. To prevent thermal stress to the VCO, ensure
gentle temperature gradients and use preheating whenever possible. (Recommended preheating: 140
°
C to
160
°
C for 60 s
±
20 s)
Always consult FUJITSU MEDIA DEVICE beforehand if mounting more than once.
Never remove a VCO that has already been mounted and attempt to reuse.
For mounting, use a general-purpose flux suitable for mounting electronic components.
