Unnamed section

The Lw given for DIP packages here is of no value. What's useful is the diameter of the hole needed in the PCB to accommodate the lead, so the dimension should be the width of the leg where it is narrower, not at the top where it's wider. 58.164.71.197 (talk) 06:31, 30 July 2009 (UTC)[reply]

Package vs Pitch relationship is incorrect

Perhaps contrary to some expectations, a particular package is not necessarily associated with a unique lead pitch (P in the table). Instead, the package name may refer to a particular package body size, with larger number of pins accommodated with finer pitch. Example: MSOP-8 with 0.65mm pitch, MSOP-10 with 0.5mm pitch.

Package vs Pitch vs Lw relationship

Lw is important for denoting pin spacing in conjunction with the pitch P. The indicated dimension for P when added to the dimension of Lw, however, results in a dimension greater than that given for the overall body length L. The dimensions given would mean a maximum of three pins are possible on either side of the body. I have examined datasheets for SN5400 chips available from vendors and find a similar problem seems to originate from that source and I believe that information comes from the manufacturer but I could not locate a datasheet with the manufacturer as a source. It may be that the information in question is considered too "ancient" in light of the present state of technology.Ted8LB (talk) 00:56, 24 June 2014 (UTC)[reply]

Scope lags title

The title says "electronics package" but the current list is exclusive to integrated circuit. The "Related" section does link to other types of component packages; much of information for those can indeed be derived from linked articles. However, this contrast makes this page even more like a "List of IC package dimensions". (And incomplete in this.) This article could be more useful with a narrower scope, as well as easier for others to improve. If no objection, I will change the title in a couple weeks.

Hello! Agreed, "List of IC package dimensions" sounds good to me. — Dsimic (talk | contribs) 08:13, 9 September 2014 (UTC)[reply]

Maybe should merge with List of integrated circuit packaging types? • Sbmeirow • Talk • 08:29, 10 September 2014 (UTC)

Done[reply]

Don't forget the exhaustive list at Surface-mount technology. And I'm sure there are other lists of trivial dimensions masquerading as encyclopedia articles all over this project. We haven't even touched transistor packages and vacuum tube packages and wire gauges and motor frame sizes (both ASNI and IEC) and the huge List of battery sizes and Fluorescent lamp formats. I haven't yet found the List of finishing nail dimensions, which I'm sure someone is working up to be a featured list. Catalog pages look just like articles to the Wikipedian.

Or we could blow away all the dimensional trivia and leave that to the manufacturer's part catalog...not one word do we expend on "why" there are different sizes, which would be slightly more encyclopediacally relevant. --Wtshymanski (talk) 14:26, 10 September 2014 (UTC)[reply]

Well, almost anything would be better than what we currently have with this article. :) — Dsimic (talk | contribs) 20:10, 10 September 2014 (UTC)[reply]

Package Length?

How many pins does L refer to? Eur — Preceding undated comment added 00:06, 18 December 2014 (UTC)[reply]

DFN Package

The Dual Flat No-Leads Package is missing. --80.157.185.206 (talk) 13:45, 22 March 2016 (UTC)[reply]
