Yes I would, most of our old Yamaha machines (before 2005) will do 30-35 microns @ 3 sigma with the fine camera option. Our Jukis with His res camera's will hit it too. You should be OK with most things after 1997 with the right camera choice (whic

Hi everyone, First post here. I am completely new to smt as well. We are a small startup and would like improve our in-house smt assembly capability from manual assembly. We are looking at small production runs, initially about a total of 200 board

There is a new toy I received today: a NeoDen TM-240A automatic desktop pick and place machine! I’ve kept my eyes on this baby for a quite a while, and finally decided to make a purchase last week. The shipping was very fast: DHL from China, a total

Have you looked into Sipad? They will pre-paste your BGA and other component areas with solderpaste that has an adhesive on it. You can then hand place your components and run through a reflow. Here's their site: http://www.sipad.com/

I would expect any half decent machine to place 0603 parts slap bang on target to the typical defined accuracy for such parts on most machines of perhaps ~60 microns or better. Self correction during reflow is IMHO much less pronounced with lead-free

Assuming you want to run 8 hours a day and 5 days a week, you need a sustained throughput of 2.5k components per hour. With fine pitch, futzing around, setup, etc you should really look for machines rated in the 4k to 5k per hour range. That's not sc

apples to apples. 20 boards 80 parts top and 10 parts bottom. these boards are done on a semi regular basis (you know the boards are coming to you from an OEM at least three times a month, just no exact schedule). All that is required is pasting..mo

Sorry 10 days passed before I replied. This happened and that happened and I completely forgot about this forum. But here's my explanation: 1. How to get parts on the board? This is a very good point, and I totally understand why you believe I hav

If you study how the process is done now, it isn't that different from what you describe. Instead of glue, we use solder paste, and instead of spraying it we screen print it. But not that different. For feeding boards we use conveyors instead of rubb

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
