• SMT Pick-and-Place Pro...
Here is a look at the pick and place process for surface mount technology (SMT) printed circuit board assembly at Z-AXIS. The newest Mycronic/MYDATA SMT lines are narrowing the gap between "high mix" and "high speed" SMT manufacturing.

I loved this job,when i was in the Sony factori🙂
Thank you for posting this. Very educational. Most companies are afraid to show their factory like this.
no ESD overalls worn by staff ?
Here's an explanation of ESD protection and audit measures in the facility: czcams.com/video/RTOZ9OzSSHs/video.html
I'm pretty sure you don't need an esd jacket to play with the stencil printer.
They use ESD heel straps.
No Gloves when handling PCBs to avoid Contamination of pads, gold and silver fingers?
Gloves are only clean until you touch some other surface with them. It's more effective to teach and practice good handling techniques: Boards are handled only by the edges, to avoid contamination.
no SPI to check the Solder paste?
This isn't a big concern a long as you make sure your stencils are working well, which is done automatically by the paste printer. We are considering adding a paste height measurement system but it's not really an issue in a temperature- and humidity-controlled environment, if you have set up the machine properly and regularly clean and maintain your stencils.
my data is the best pick and place machine ever
We like their performance and flexibility!
ESD? Long hair and no smocks? I miss that old job......
Hope you're doing well! We talk about ESD control in the related video: czcams.com/video/RTOZ9OzSSHs/video.html. A lot of factories seem more concerned about the "look" of things and set up practices that don't add to their effectiveness but just make employees unhappy. People like to express themselves with clothes, hair and jewelry and when they have the freedom to do that at work, it makes a happier workplace. Happy employees do better work.
Agreed. Let's focus on the essential part - reliable product.
01:32 thats not good. its better when the pcb dont move!
It depends on your SMT equipment. Some pick and place machines move the placement head in all three directions (X, Y, Z) over a stationery board. Others move the head in two directions (X, Z) and move the board in the third direction (Y). Both techniques are fine. This modern Mycronic MY200DX machine has a 4 sigma placement accuracy of 35 um -- well capable of placing our 0201's (508 um long and 254 um wide) to much better than the IPC Class 3 standard.
you can set the Y-acceleration for each package the software uses the lowest that's already placed on the board for the Y movement. The bigger components like electrolites have a lower setting they are placed by the second machine with the larger single head, since the head has to go back and forth for each one the Y fasteness doesn't matter there. I've disabled the fastest setting on the second machine anyway for 'safety'. Sometimes you have to 'repair' a board or place a component that came in late so you have to feed the board in the machine for a second time with all components mounted the machine will load the board at the fastest setting in that case because it thinks no component is mounted yet. That will wreak havoc with heavy coils running wild and destroying everything in it's path like an elephant.
no esd strap when inspecting your boards? smh
Good eyes, Eileen! Everyone in manufacturing wears two heel straps, which is acceptable ESD protection per the JEDEC standard JESD625B. The heel straps are tested twice per shift. These grounding straps are only the last line of defense against ESD, which goes much deeper at Z-AXIS. For more details see our related video czcams.com/video/RTOZ9OzSSHs/video.html .
Heel straps are visible in video at 3:31.
There is an "l" in "solder". Why do yanks miss it out when speaking the word?
¯\_(ツ)_/¯
The table moving will is not good the part will fly off the pads bad look like mydata machine is good for small build like capacitor or resistor
The moving table works great. The machines handle a wide range of SMT components at excellent placement speeds and no parts fly anywhere.
