Assembly Guidelines:
1. Follow solder paste manufacturers recommended profile
2. The profile illustrated in JESD-020 and below is for reference only.
3. Profiles must be dialed in to the specific assembly type.
4. ENIG finishes are more susceptible to voids and air entrapment.
5. Recommended finishes for LGA/BGA inclusive assemblies include HASL, OSP, Tin,
