Direct Press Diode

[sablehilt]

Hey LPF,

I ordered Yobresal's Blue ICE JAD kit, and it comes with a "direct press heatsink" does this mean that I just put my bare m140 diode into it using a rag covered vice? or do I need to be very careful and do it some other way?
I'm looking very forward to assembling this kit.

Yes a direct press heatsink is one that does not use a module, you will need to press the diode directly into the heatsink. Assuming you've pressed diodes properly before using a rag covered vice, this method would be no different except you're pressing into a heatsink instead of a module

I have never pressed a diode into a module or Heatsink. This is my first DIY laser. Any tips for pressing the diode into the Heatsink? Does it need to be flush?

I would suggest getting a diode press because it's simple to use & you can be sure you press the diode completely straight. I'm sure someone else will chime in on a few other ways to do this but I'm sorry I can't suggest any.

You also want to press your diode slightly past flush like this

Will that diode press work on direct press heatsinks?

If the opening in the heatsink is larger than 10.5mm in diameter then a diode press should work because it would be thin enough to slide in there and mount the diode. You could use a vice or pliers (I use a clamp) to press it. Otherwise no because it's made for pressing diodes into modules
