What's Up with Surface Mount Terminal Blocks

I think id be happier with a through hole type, or at least bolted/riveted to the board.

You can get plug in type terminal blocks wich are basicaly like a normal plug and socket, but where the plug is effectivly the terminal block.

Lack of stress?

use a real block with pins

They actually work fine in low vibration environments. Adding several small vias to the trace (or copper flood if the part is large enough) helps to anchor the connection to the board and prevents the copper from delaminating or otherwise pulling free.

The worst part is actually controlling the oven well enough to prevent the plastic from scorching while still getting a good reflow. Not all terminal blocks can be put through an oven. I use alot of Phoenix Contact parts, and none of the parts with green plastic can handle the oven.

Sufrace mount terminal blocks?? This sounds like a really bad idea.....

Next thing you know, we'll have surface-mount definite purpose contactors....

Yeah..I know.. But I'm going for a full SMD design.. I'm using terminal blocks to allow for connection of any cut length of wire. There's a very good chance I'll just bend the leads of a normal terminal block and surface mount it... I'll also epoxy it to the PCB. D from BC

I use those 0.1" headers and just solder them horizontally to the side of the pcb, or use the right angle types, but I'd stop short of doing that with terminal block types.

it would be easier to do a few solder joints by hand than to glue it anyway.

We already have those. The surface is a subpanel.
