The problem here is that the chips are not at a uniform height. They vary due to the reflow process. In order to assure you have no air gaps, you may have to go a bit thicker to assure they all have contact. So add a dot, squish down then lift up and check the spread. If it’s good, then screw down. Every driver is different.
I like the idea of the dot being somewhat tall. The extra height should guarantee contact as opposed to spreading a thin layer over all the chips.
I see no issue if it spreads slightly past the edge of the chip.
Just received my piece today. Very nice! Took 5-10 minutes to install. Fixed! Llght head warms up within 30s and continues to warm but no early step-down. The included stickers are a nice touch. I used Arctic MX-4 compound. This is a very high quality mod that works. Thanks very much man of light.
Out of curiosity, would it be too late for the supplier to increase the batch size of the second batch instead of doing a third batch? Would possibly be better piece price being a larger run.
I was already thinking about it, unfortunately it’s not that easy. The 2nd batch is already manufactured and will be delivered to me mid of this week. I have to think carefully about every order, as it is a certain risk for me and costs arise. That’s why I can’t just order large quantities.
But anyway, I will contact the supplier and ask him whether he got some more material left and is able to deliver a few pcs more. Cause the interest is high and I try to speed up the availability.
Edit: Btw, I wonder if it would possibly be a good idea to just ask banggood or any other retailer selling this light if they would be interested in buying a set number of these heatsinks, just so you would know how many you could order yourself for a 3rd batch ;)
Thank you very much man of light!
