LITEON DG-16D4S - SLIM Best size PCB drill for Kamikaze?

[360Player90]

Now before i start i know this is a TX support site for TX products, and i have bought myself many replacement PCB's So still have many original (none unlocked) PCB's left over.

So what would be the best PCB drill size to get it just right?
(the old drill got blunt/broke)

These are the drills i am working with:

Sizes are:

0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2mm

Thanks.

I would try find one a bit smaller than the smallest you have there (0.3MM).

You can use from 0.8mm to 1.0mm should be fine

I like to use 0.5mm

 

[360Player90]

A 0.1MM drill bit is fine.

WOW really, this 0.3mm looks as small as a hair strand.

I only said that because the two bond wires you need to cut are almost invisible to the naked eye.

I use a very fine screwdriver to manually make the hole in the chip.

i prefer to use the 1mm bit to mark the spot with the template,then step down to .8mm to do the actual hack,rarely fails.

I've seen kamikaze board's with 1.5 mm holes and they seemed to work fine.
It's the accuracy of your marking and depth you drill to thats more important.

This is exactly what i do

I suppose if i could mark it to the exact MM then the 0.1mm would be fine.

But marking the actual chip will be a problem to get it to the EXACT 0.MM (no?)
I normally score the chip with a razor

This sounds like a good idea, Thanks for the tip

only part that sucks is u need to order quite few .8mm bits,as thier only good for a chip and a half avg before u need a new one.

I use my hakko fx-951 and alot of others use an iron as well. I have not failed one yet using it.

Have been using a x-acto knife from the beginning. You can easily do 5 boards with a blade before you need to replace it. Never had a fail, but like others said, it's very important to choose the exact spot.

A nice tip I've read from Martin was to (if you have one) use a micro USB, take a close up pic ofthe chip and use paint to line out the spot. You'll then know exactly where you can drill

Yeah well actually not a hint, more of a statement. I found it resourceful

But now I understand I gave the wrong person the credit. Lol

Recommend this method many done this way, no fail yet

I use the same method and I've not failed one yet.

geremia's original hack was with a 0.8mm engraving bit.
1mm is too large it should only be used for marking out with a template.
its a compromise of not too large to hit other wires and not too small as to miss the one you are trying to hit,
0.8mm is the correct size.

I use the .8mm engraving bit, afrer a few drills it get a bit worn and drills slower wich makes almost no risk of drilling to far.
