We have been using IPC-SM-782 specs for years and have no problems. We
request that are customers use the IPC-SM-782 specs when designing there
PCBS. Some questions have come up in regards to the IPC-7351 specs, which
some of our customers are using for there designs. We typically review the
chip components on all of the boards we manufacture, in doing so I came
across an issue where the chip components specs have changed between the
IPC-782 and IPC-7351. My questions are:
1). Have the IPC-7351 specs replaced the IPC-SM-782 specs?
2). Which spec should we be designing to?
3). Why have the specs changed?
4). Are the IPC-7351 Specs incorrect?
