Application Note

1. Panel Mounted Shrouds
   
   In low profile, blind mate applications, flange mounted shrouds are used with "bullet" adapters to provide axial and radial "float" for a proper fit. The bullet adapters mate to glass-to-metal sealing pins that are welded to the panel. In these applications, one shroud is typically a "limited hold-down" type and the other a "smooth bore" type. This pairing minimizes mating and unmating forces and retains the bullet adapter in the "limited hold-down" shroud when the panels are separated. The space between panels when mated can be varied by using bullet adapters of varying lengths.
2. Mounting Support Bar Spacing
   
   For units with 0.223" wide flanges, the shields can be mounted as close to 0.230" centerline spacing. Narrower flanges are available to allow spacing as close as 0.170" (4.3mm).
3. Seal fixing tool

Sealing means

• Drill the panel as shown.
• The front of the seal should be as flush as possible with the front of the panel; if the front of the seal is lower than the panel surface, an air gap will result, adversely affecting electrical performance.
• The front face of the seal should be flush with the front face of the panel but may protrude 0.005 inches without affecting performance.

Welding ring

• Create a solder ring of a size that will completely fill the panel top hole when melted.
• Place the pre-welded ring into the top hole of the tool.

1. 

• Secure the tool to the panel with screws.
• Apply heat to completely melt the solder.
• The tool may only be removed after the solder joint has cooled.

1. 

• Secure the SMP cover flange to the panel with screws.

What assembly is this

How many degrees Celsius does it take to heat the solder completely?

It depends on the material used and the application environment.

Thanks for the technical sharing provided by the host. I will collect and study it first and then express my personal opinion.
