In-house Pick and Place for $60,000

(1/2) > >>

Piotrek:
Hi,
we are looking for a pick and place machine that we can put in the house, so it has to meet two requirements: firstly it must weigh no more than 400 kg, and secondly it must fit through a doorway. With a budget of $60,000 (including feeders) the obvious choice seems to be a used "professional" machine like a Yamaha, but we lack the space for such a machine.

Chinese machines like neoden are already insufficient for us. They lack precision (even up to 0603 and 0.5 mm pitch housings) and require correcting the components after finishing the board with tweezers. Not to mention annoying feeders.

The closest to meet these requirements is Fritsch machine, but a new one exceeds our budget and there is no used one on the market. Do you have any ideas how to solve this problem (apart from buying a bigger place for the big machine)?

SMTech:
Probably the most compact and common pick and place in Europe is the TWS Quadra, definitely get those in your budget.

 Essemtec FLX/Pantera https://www.machinio.com/?location=&page=2&search=essemtec#quickview/56748039 should be possible too, but I'm not sure on the size of your doorways. However easily get several older ones of these in your budget.

Autotronik https://www.autotronik-smt.de/en/products/smd-bestueckungsautomat/bestueckungsautomat-bs281s this is the smallest one they do but there are several others comparable to a Fritsch. I get the vague impression the 281 model may have issues/compromises as I've seen a couple of instances online of people who have got hold of second hand machines with no PC and can't get support for it. https://tools.adoptsmt.com/equipment/?language=en&id=41600 but here is a 2nd user one possibly

http://www.mechatronika.com.pl/ - These are almost certainly crap, but you can see some user video on Youtube and they are local to you which might make support better.

I think you should find the Chinese machines that start around the $20k do 0603 & 0.5mm pitch just fine, so the more expensive Neodens, & Kayos that don't claim to work on a benchtop.

If you haven't already maybe try Miro @ https://smtbroker.pl/

I want to point out that the lighter the machine is then the slower it will operate. Machines need to be heavy so that they don't jump around when the gantry arm is moving at high speeds.

"Fit through a doorway" is also a bit vague - what size is the doorway in question?

Piotrek:
@SMTech

Thanks for your PnP suggestions.

We considered the TWS Quadra, but the accuracy placement is at 100μm, which is not the best result.

I have sent enquiries about used Essemtec FLX but always used equipment carries a risk and in the end something may be wrong. To avoid unpleasant surprises you need to have experience and check the machine well before buying it, which unfortunately is not always possible.

Autotronik looks ok, I am waiting for an offer from the distributor.

My (and not only my) opinion about Mechatronika is negative, I am not going to buy a machine from them because of their approach to the customer.

@Mangozac

We realise that a large machine is more stable and therefore has a number of advantages, but unfortunately we are not in a position to put something this large in our production facility.

The doorway is 90 cm wide, so we should be able to fit several of the machines mentioned above. We have learned that it is often possible to split the machine into two or more pieces, which makes it much easier to move.

Not entirely correct. Yes, higher masses will generally provide more vibration dampening. But that's just the brute-force solution. Doesn't mean it can't be done more weight-efficiently.
