I just saw an ad for a Yamaha IPULSE M20 SMT placement machine. Is there any other manufacturer doing this?

I like removing unnecessary steps from my production line.

A stencil prints thousands of apertures in one squeegee stroke. Stencils can be bought for less than 200.00

Even in a prototyping application I cannot see where a machine like that could be cost effective.

Mycronic is making jet printers forever. Great for prototyping and small runs.

How do you justify a 200K machine for doing small runs and prototypes ?

With saving time and space. With having the possibility to change any aperture at any time. With having the chance to apply different deposits on the same assembly or the same part. A stencil printer is not for free as well and it needs consumables too.

MY500 on a NPI/Proto line makes a lot of sense and can really cut down on costs and downtime due to stencil revisions/issues. Especially once you have a 250 line BOM loaded on the line and you find out the stencil has a couple of critical apertures incorrect, change the MY500 program and keep running, or reorder the stencil and either tear down the entire job, or hold up an entire line for at least a day.

If you need to make changes to a stencil that many times someone is not doing their job properly. In the past 16 years I have had 3 line stoppages due to stencil issues. 2 of those were because the board house made the panel differently than the files they were sent. New board house solved that issue. I agree with Sr. Tech It's not possible to justify the additional cost.

Hard to say without knowing how someone's business/shop runs and the profits they make off what's produced.

That's the crux of it. We have volume and prototype lines & use a lot of stencils, so would be better for us just to get a stencil cutting machine for a similar price. However if we just did low volume /prototypes then we could make a case for it.

However the OP is talking about a machine that replaces a placement nozzle with a dispense head. This is a $20k upgrade that runs at a fraction of the speed an inline stencil printer or Mycronic dedicated dispensing machine. Essemtec offer a similar option (actually I think their options might be better). However replacing a printer is not their primary market, instead these machines are aimed at PoP, 3D assembly, glue dispensing, PiP or cases where additional paste might need to be dispensed after stencil printing. Certainly you could replace a printer for low volumes, but that won't help if the board is complex, it will still be slow.

Which model Essemtec? I am looking for something like this.
