How to remove heat sinks on Antminers and mount Water Blocks - Video

[alex1560]

Hey guys,

I recorded a video of my process of installing the waterblocks on the Antminer S9 board.

Check it out and let me know your opinion, if you have questions post them on this thread.

Good work gave you 3 merits.

to sand chips fast  buy this

cut it with your cnc machine so it is a grid

lay it on the pcb only the dirt chips  are exposed

sand with this

only the part to be sanded is exposed

you have built a holder for the board  build a template for sanding   bro  you will like it.

Thank you for the merits!

Thanks also for the suggestion on the youtube video. What I was thinking is to make such a template on my cnc machine to hold the board perfectly straight then program the CNC to go over each IC and make it perfectly
smooth. This will require a few days to get it right, but will allow saving a lot of time and make perfect job in the end. Maybe will do in the future and make a video of the process as well.

I linked  a blank plate and better sanding products.

Where are you located I have a good friend in the brooklyn navy yard  he has a wood working shop  he reminds me of you.

I understand what you are saying, trouble is that the template needs to be very fine to do that as the chips have only 1mm thickness.. and you won't be getting them through the template to sand. But I got your point.

I am from Romania, a bit East from Brooklyn .

My friend is also from eastern europe. He came here 10 years ago.

I knew chips were thin I thought they were a bit taller but if that thin  I think setting it up with your cnc to do a pass may work better.

Yes, it's tricky business, but it can be done.

this will be risky as hell, i assume you talking about cnc router and not laser since you want to use it for cleaning the IC's ! . setting a perfect Z point on your cnc with 0% room for error is nearly "impossible".  you will need a 100% flat ground " maybe take an MDF sheet and perform an area clearnce with your end mill to get that flat surface" , but then again i doubt the accuracy of your cnc will be safe to try and risk the IC's.  philipma1957's idea of making a format for cleaning would make more sense, but you will need a laser cnc to do that. it will take sometime to set up perfectly, but will make your job much easier when sanding those ICs.

should you decide to go for one , i can help . i have a tremendously good experience working with cnc machines.
