I was wondering what type of machine would be the best for high production rate of small pcb boards. A rate of somewhere near 800,000 units a month on a board that is approx 1"x2" 4layer with 20 components.

If.........

1) Assuming you are panelizing them (you would have to actually).... 2) You don't have any fine pitch parts on the board then I would suggest a chipshooter like a Fuji CP-6 or a Panasonic MV2F.

Get (2) of these used for around $100K each and you can handle this job with each machine running (2) shifts.

Fastek will get it done with 2 machine and 2 shifts. 2 shifts would need to place 50,000cph. One CP643 with both device tables set could get it done. Having it panelized in 50's, you would need to print 50 panels a hour so get a auto cleaner on the printer. There are board loaders which would give the operator more than enough time to have some feeders always ready and push the boards in the oven. Getting this panilized in say 100's would need to put a panel out every 2 minutes. This is assuming only small components. If you have 20 different components needing to use even 3 different nozzles requiring the table or turret to go below 90% look at two machines. I don't know the speed on the cp8 but I think the Cp7 was up to 80,00cph. With the CP643 and later you save the valuable few seconds for board change.

Take a look at Assembleon. The AX-5, similar to the older FCM, is ideal for running smaller PCB's and has one, if not the fastest IPC board speeds in the market. Something else to think about is to purchase a line. If this is an option, many equipment manufacturers will be able to fit your needs... more manufacturers trying to sell you something, the less you have to pay for it.

I assumed a conservative 25,000 cph for each of the chipshooters...whether it's an MV2F, CP-6, CP-642 etc.

You're not going to get 50,000 cph out of (1) CP-643. You might for short periods but not in the long run. It would be suicide to rely on one machine like a CP-643 to be able to accomplish this output. That's why I say get (2) chipshooters....have some extra capacity to spare...for around the same money as a CP-643 and comfortably be able to handle the job without all of the stress of trying to do it all with one machine. That CP-643 goes down at all and you are dead in the water. At least with (2) machines you can still produce if one goes down.

Hey Peter,

Did some simple math...

800.000PCB's x 20cmp = 1.6million placements 8hrs/day * 22 days/month = 176 hrs

You're looking at over 90kCph fulltime!

I'd say go with an AX-5 as JAX suggested. Given the product you described you could reach speeds up to 140kCph on a single machine, so you will have some spare time to do cope with variations in demand. By the way: your board is very small (1"x2") so you may have to get the special board-transport for very small boards. I believe they sell those too.

I wouldn't go with the AX-5 - it's overkill. To make a board in high volume that sounds that simple is a job for a second user chipshooter (Fuji or Pana)as the first reply mentioned. Stay away from FCM1's.

I'm sure the AX-5 is a great machine, but it has many wonderful things that you will be paying for & won't need (super fast changer overs etc)when making the same board day in day out.

If you do buy new last time I checked the latest Fuji Chipshooter was $350K
