What&#;s the SMT feeder?

In the Surface Mount Technology (SMT) pick and place machines, a "feeder" refers to the component feeder, and it is responsible for supplying electronic components, such as resistors, capacitors, and integrated circuits, to the pick and place head of the SMT machine. The pick and place head then accurately picks up these components and places them onto the circuit board according to the programmed design.

SMT Feeder types

There are two main types feeders, electric feeder and pneumatic feeder. Both feeders have own advantages, and play a crucial role in the automated assembly process. In the post, we will compare the main differences between electric and pneumatic feeders to help you make your right decision for your SMT pick and place machine.

Pneumatic feeder can provide a higher speed, but electric feeder provide the most precise control since air and fluid pressure are more difficult to control than electricity. The choice between electric and pneumatic feeders for SMT pick and place machines depends on factors such as the required precision, speed, maintenance considerations, and the specific requirements of the assembly process. Some SMT machines may use a combination of both types of feeders to optimize performance for different components and assembly stages.

Just to be clear my machine is not SMT440 neither SMT460. My machine is sold by the YX manufacturer called JIM and the machine that I bought was a SMT460 but he sent me other machine.

He sent me the HW-T4-42F and is made by SMTHW.com They have 2 versions of software and firmware. The older version and the new version. The version seems to be made in better english as well as the manual for it. The older one was made very poorly or with google translate. The old software however was more complex and you had more buttons and parameters to adjust in the PC software itself.

On the new software it looks more easy but it for the moment I didn't find how to test the feeders or align the nozzles , pick up height from the feeders, height on the pcb etc .. With older software this was much easier to see and to configure. This is not the problem. 

The problem is I had a working software the old version and everything worked perfect. Jim told me to instal the new software and the new software was not ready as it should have.

Before I installed the new software I did a backup of the parameters on the old software. Few days ago I got the firmware for the old software back and the old PC software. I installed it and finally I could go back to the old software version. The problem is that some things are messed up. Everything except the x,y and z is messed up. The nozzle works , the vacuum of the nozzle works, the X and Y limits seems to be ok. But the feeders and camera's are mixed. The feeder number on the machine do not correspond with the number on the software. Worse .. some numbers on the pc software does not do nothing at all.

For example number 42 on the PC software is number 4 on the machine. Number 28 on the PC software does nothing at all .. and many other numbers are mixed. This is related to the parameter file if I'm not mistaken. The other problem is the LEDS of the FAST cameras and the HIRES camera does not work. Also the MARK cam goes on when you choose FAST cam on the PC software. So it is mixed up again.

The strange thing is that I even tried again with LOADING my previous parameters I have saved. I had that old backup so I uploaded and still the same. I also have noticed something and was just curious. The firmware files are not so big. There are 2 mcu's on the machine end. Main mcu and slave mcu. Main mcu have a 24kb .DFU file and the Slave mcu firmware file is about 6kb. After I upgrade the mcu's and try to upload the files to the PC I get kb for the main and kb for the slave. I know this is the size of the mcu but why does it uploads the whole memory ?
