Andres, I think if you were to understand the process a little better you would realise the many many problems you would encounter building even very simple things using your method. Even 30 minutes watching Youtube videos of current machines might h

If the thermal mass of the products is small, a tent-shaped profile is recommended, with peak temperature around 240C. The hottest spot on board should be less than 250C. However, if the thermal mass of the product is large, such as a large server PC

I have a Siemens S-27 and I'm having occasional issues with 0201 components in particular. I'm using the 12 segment head and 902 nozzles with them. I'm making sure the magnet is clean of debris and the feeder is sitting flat. Most of the time they

Sorry for delay - been flat out. Sr - I understand what you are saying. My concern is that combined with the head offsets and variations in pick points (i.e. having to teach feeder positions for very slight amounts like 0.05mm)then you cycle times wi

1 - Too messy, parts already come in nice easy to use machine compatible packaging, tapes, reels, tubes and trays. All you are doing is adding an extra step and complication. A key production aim is to reduce the number of steps. 2 - BGA - a chip wi

Assembleon AX201 is one of the most accurate odd-form placer. It can place anything, including leaded transformers, press-fit connectors, and of course odd form SMT components. You can even use a gripper nozzle for components without a flat surface t

I dug through my big box of office crap and found the disk with my technical papers. I posted the one on process control in the SMTNet library. It covers a lot of ground on what causes defects in the wave (too much or too little of something), and
