Hi Carson,
From an SI-prospective Press-Fit and Through hole perform worst compared to
SMT. Only Mechanical or Production related reasons would be arguments to not
use SMT. Some Military electronics require press-fit or through hole
connectors, SMT is prohibited, and I think that’s the main reason why you can
buy those.

Subject: [SI-LIST] Pros and Cons of Through-hole / SMT DIMM Sockets
Hi experts,
I've always wondered about the availability of through-hole / press-fit and SMT
versions of DDR3 and DDR4 DIMM sockets
<http://www.molex.com/molex/products/family?key=ddr4_dimm_sockets&channel=products&chanName=family&pageTitle=Introduction&utm_source=dpb&utm_medium=lit&utm_campaign=general&WT.mc_id=A03253>
.
Are there any signal integrity tradeoffs here (I don't see any relevance here
at DDR4 signal rates and edges)? Why would someone consider through-hole over
SMT? Are there reflow or mechanical issues?
Regards,
Carson
