I purchased a used QUAD 4C -136 and after a few months got the machine running 8 hr shifts. One issue I have come across is feeder drift. I kept re-aligning the feeder pickup positions but they would always change. Finally I got the time to measure

Quad 4c's would be a great machine for what you are looking for. They are easy to learn for an smt machine and very reliable. Just realize that when you buy a machine that is no longer being improved...you can run into limitations. Those machines are

I use a Philips topaz, Have been running them for 6 1/2 years and have had great luck with them and assembleon is about as good as it gets when it comes to tech support. I am not a vendor just a machine operator. I am familiar with the quad 4c and th

Tim, 1. You dont need the vacuum verify if the quadalign is working properly. If you have the part quad-aligned and dont have alignment type at 0 it will never 'not' place a part. More or less...the vac verify was needed for the chucking machine (3c)

Does anyone have an idea of what a good placement rate (pph) is for a low volume, high mix smt line? We do small lots (10-300pcs), with a feeder count that ranges from 28 to 130 per setup. We have low volume machines (an old (real old) Siemens HS-180

Hi again Bob, I checked the theta motor coupling and the set screws are definately tight. I noticed that the theta motor drives an snti-backlash gear (nice design) so there is no play there. It appears that the gear drives a slotted shaft which is d

Bobpan, thank you for your speedy response. As to the items you noted: 1. I did a test of Funct 30 for the first 5 nozzles, 2 times each as follows: noz1 Ht=215 & 219, center=1005 (all nozzles all tests), run out 2.2 & 2.7. Noz2 Ht=228 &228, runout=

Hi again Bob, I'll go by your item numbers: 1. OK, I'll not worry about it. 2. Somehow, it seems to me that it must be doing something or in Run Step Placements there wouldn't be different behavior for Alignment type 0 vs. other settings. I know I'
