[sci.electronics] PLCC SOCKETS

johng@phred.UUCP (Screw Man) (01/06/87)

Has anyone had any experience with PLCC socket reliability?  We have been using
PGA sockets here with good results, but have heard that PLCC sockets have
had a poor reliability record.  Any information on good or bad brands of PLCC
sockets would be helpful.  If you know of any reliability studies conducted 
on PLCC sockets that would also be helpful.

We have had very good results using Burndy PLCC sockets.  They are very
reliable, have scope probe holes, and cost less than most of the other
brands.

One brand to stay away from is, well, so I don't get sued, A*P.
Maybe you can guess what the Middle initial Might be.
Their brown molded PLCC sockets are the pits, and cost us a great
deal of extra debugging time due to crappy connections.

Good luck entering into the exciting world of PLCC's!

As a component engineer I personally tested out some 68 pin PLCC sockets for
use in a new product we're developing. As far as I could tell, the overall
best PLCC sockets are from Burndy, Methode, and Yamaichi. All of these are
based on high pressure tin contact design, are relatively cost-effective and
reliable, and use the same extraction tool (namely the Burndy QILEXT-1 extrac-
tion tool). If anyone is interested in further information please send me
some e-mail to the effect.

				   Yours truly,  BIG DAVE.
