I read the request months ago with great interest. However, a request is hardly an exemption. Here's my issue with the language: "23. Lead in finishes of fine pitch components other than connectors with a pitch of 0.65 mm or less with NiFe lead fra

Sure the bake need to be done after BGA replacement? Normally the board need to be backed before BGA replacement (not only)in order to avoid PCB delamination due to moisture entrapped during his life staing on field. Oven Temperature from 90 to 125

In this work the reliability of an embedded planar capacitor laminate under temperature and voltage stress is investigated. The capacitor laminate consisted of an epoxy-BaTiO3 composite sandwiched between two layers of copper. The test vehicle with the embedded capacitors was subjected to a temperature of 125oC and a voltage bias of 200 V for 1000 hours. Capacitance, dissipation factor, and insulation resistance were monitored in-situ. Failed capacitors exhibited a sharp drop in insulation resistance, indicating avalanche breakdown. The decrease in the capacitance after 1000 hours was no more than 8% for any of the devices monitored. The decrease in the capacitance was attributed to delamination in the embedded capacitor laminate and an increase in the spacing between the copper layers.
