Hub Module THD Components ----------------------------- Rev. 10-Feb-2017 The purpose of this note is to describe all of the Through Hole Device (THD) components that the assembly vendor needs to mount onto the Hub Module circuit board. The Hub Module uses 6 types of THD components. The following tables lists all of the THD components and shows how many of each type are used and whether they are soldered into the PCB holes or press-fit into the PCB holes.

This support of the back side of the PCB can not interfere with any of the SMD components that are mounted there. - It is very important that the ATCA Zone 1 and Zone 2 connectors are evenly and fully pressed in, that they are not overly pressed in and thus crushed, and that all 6 of them line up in a straight row. - The ATCA Zone 2 connectors have 160 rather small and easy to bend pins for a press-in component. - Failure to properly install the press-in Zone 1 and Zone 2 backplane connectors would be a big problem for us. - The 2 power modules have some heavy high current pins that solder to multiple layers within the PCB. These pins will be difficult to solder high thermal mass connections. Some pins on the 12 Volt DCDC converter carry up to 25 Amps and must be fully and properly soldered. More information, including installation instructions, for these THD components can be obtained from their manufacturer's web sites. Many of their data sheets and application notes have been copied to the MSU Hub Module web site.
