Index The index to this thread is found in post number 903 Go to INDEX. [IMG_3826] How about sharing some tips you use? Here is one I use often when I need my third hand to give a constant pull. [2017-01-04_0-01-26.jpg] .

TKall: Are those 4 flute? Yes but two or three would work too. .

Make sure you take the radius of the bit into consideration/quote] Is this handled in the machine software with end mill selection and offset? I don't have to draw the part differently, do I?

I do everything with AutoCAD so I have to take cutting bit diameters into consideration in my head/drawing. :frowning: .

LarryD: :o 0201s :o Don't sneeze! Nothing wrong with a tooth pick if it works. I used a dental pick for a while. I assume you have a Microscope. [image] 008004 That's just not right :slightly_smiling_face: ...... Very proud of myself lately, soldered 008004 to the board, was not easy but not as hard as I thought it would be :slight_smile: I would take a picture of it sitting on a fingertip but it is so tiny it is just invisible :slight_smile: You can probably fit bunch of those into 0201 by volume :slight_smile: [008004_2.jpg]

Good work. .

tinman13kup: Impressive, but how many did you lose??? I only had two because they cost $.53 each so I was very careful and did not lose any of them but I tell you this, you do need microscope to just get them out of the package and keep an eye on those things at all time they are so tiny that once you look away you may no longer find them on your desk :), and as I was taking them out of the tape I can clearly feel that one wrong move and springiness of the tape can send them flying so you gotta be very careful and perhaps use two tweezers to take them out. Soldering will require different technique because dispensing such tiny amount of solder paste manually is very hard and even using needle to dab little blob of solder paste is impossible because pads are so small and even at slowest air speed they just getting blown off pads so you have to tip the pads first and only heat board in a way so that air does not blow those thins off. To me it was like quantum mechanics of surface mounting, at sizes this small laws of physics stop working :slight_smile: But in general its very doable task I want to do it more in future to keep concentration in good shape.

I had to do some rework replacing 0603 resistors at work a few weeks ago. I affectionately referred to them as "dust". They're freaking boulders compared to those 008004s!

alexmg2: But in general its very doable task I want to do it more in future to keep concentration in good shape. [008004_1.jpg] Looks like you need to get a jig to hold them down on the board too. It looks like the 0603 is good, but the 0402 is a little canted, and the microscopic one is tipped pretty good. Seems to be the break point where I was running into problems keeping them straight and tight too, but I'm only planning on going 0201 as the smallest. I just don't have the dexterity in my fingers anymore. The microscope is in the works, just haven't gotten around to it yet,...work comes first.

You can make awkward to mount components breadboard friendly using: DuPont connectors, some plastic sheeting and some glue.

Sourcing more reliable breadboard buttons?

Potentiometers for breadboards [solved]

How do I wire a three-connection snap-action switch/limit switch on a breadboard?
