Here are the 15 Standard Surface Mount Terminal Lead Forms represented in the IPC-7351 and IPC-7352. 

The first bend in the lead is referred to as the Knee. The second bend is the Heel and the end of the lead is the Toe. 

For Grid Array and BTC leads, the solder joint goal is a Periphery.

The anatomy of the human leg is used to determine the Surface Mount Toe and Heel of the solder joint definition.

Topografske Karte Jna -

Here’s a structured write-up for (Yugoslav People’s Army topographic maps), suitable for a blog, forum post, or collection catalog. Write-up: Topografske karte JNA – The Hidden Cartographic Legacy Introduction For collectors, historians, and outdoor enthusiasts in the Western Balkans, few documents offer as detailed a view of the region’s terrain as the topographic maps produced by the Yugoslav People’s Army (JNA) . Created during the Cold War era under strict military protocols, these maps represent a unique fusion of military precision, socialist-era state secrets, and lasting practical utility. Historical Background The JNA began systematic mapping of Yugoslav territory in the 1950s, following Soviet cartographic standards but quickly developing their own distinctive style. The effort was massive: by the 1980s, the Military Geographical Institute (VGI) in Belgrade had produced complete coverage of the SFR Yugoslavia at scales from 1:25,000 to 1:500,000.
