Technetters,
Please let us not throw the baby out with the bath water. I would hate for
VIP technology to get a bad name when in essence your valid concerns are
associated with larger vias than used in HDI technology. A similar panic was created
against dry film soldermasks because the commonly used dry film mask
thicknesses were around 0.006 in. When mask manufacturers introduced high conformance
thin masks (0.001 - 0.002 in) to address the needs of SMT , everyone shunned
them because they were "dry film", when in reality their gripes were with the
thicker cousins.
Regards,
Gary
