/ Electrical reject devices from the same inspection lot may be used for all subgroups when end-point measurements are
not required provided that the rejects are processed identically to the inspection lot through pre burn-in electrical and
provided the rejects are exposed to the full temperature/ time exposure of burn-in.

/ Subgroups 1, 4, 6, 7, and 8 have been deleted from this table. For convenience, the remaining subgroups will not be
renumbered.
3
/ Resistance to solvents testing required only on devices using inks or paints as the marking or contrast
medium.
4
/ All devices submitted for solderability test shall be in the lead finish that will be on the shipped product and which has
been through the temperature/time exposure of burn-in except for devices which have been hot solder dipped or
undergone tin-lead fusing after burn-in. The sample size number for solderability test applies to the number of leads
inspected except in no case shall less than 3 devices be used to provide the number of leads required.
5
/ Test samples for bond strength may, at the manufacturer's option, unless otherwise specified, be randomly selected
prior to or following internal visual (PRESEAL) inspection specified in method 5004, prior to sealing provided all other
specifications requirements are satisfied (e.g., bond strength requirements shall apply to each inspection lot, bond
strength samples shall be counted even if the bond would have failed internal visual exam). Unless otherwise specified,
the sample size number for condition C or D is the number of bond pulls selected from a minimum number of 4 devices,
and for condition F or H is the number of dice (not bonds) (see method 2011).

/ In-line monitor data may be substituted for subgroups D1, D2, D6, D7, and D8 upon approval by the qualifying
activity. The monitors shall be performed by package type and to the specified subgroup test method(s). The
monitor sample shall be taken at a point where no further parameter change occurs, using a sample size and
frequency of equal or greater severity than specified in the particular subgroup. This in-line monitor data shall be
traceable to the specific inspection lot(s) represented (accepted or rejected) by the data.

/ Electrical reject devices from that same inspection lot may be used for samples.
