Hello! You may want to be more specific whereas each of those companies produce different machines. You have basic introductory machines, and high-end machines. Some provide faster speeds, some provide a wider range of component handling.

Hi all, I have never had to run a product with BGAs on the bottomside of a double sided board. I was just wondering if this is a done thing ? or should I stay well clear. any replies appreciated. aj...

It can be done. But as Rob states, use edge rail oven. We have a product 18 inches long by 9 inches wide with BGAs on both sides.

Yes, PROMATION has customer's using laser to solder PCBs. This is too broad of a forum to discuss openly so please feel free to write me at: Gary_Goldberg@pro-mation-inc.com Perhaps I can assist Gary

My advice is the technology is not there unless your boards have been designed for laser soldering. Even then there are too many limitations to go into it. We tried a unit for almost a year and were never able to get consistent, not even going to m

I agree with James. Granted there are a variety of lasers to try, we too could not get a consistent power setting. Plus when paste turns liquid, you get some reflection. Also the mask around the pad has to be pulled back or burning may occur.

If the goal is selective soldering (not to raise the substrate temperature too high), consider the use of microwaves. Our company has been working on this technology for selectively bonding substrates. For example, we use the process to bond ROHS met

Hi Krebbe, Why not trying DEK 248 with vision. It's a semiautomatic printer with fully fine pitch capability, works just fine!

I would agree with the above. Epoxy is the way to go. You can have it formulated in different thicknesses and cure times, but you need to watch out for the exothermic heat from the curing.
