We have developed a Cost of Ownership model that incorporates a number of factors when considering SMT equipment. There are the obvious ones like maintenance costs, labor costs and shift patterns. We also considere utilities, quality, set-up time a

80??? Whatever leads to you to that assumption? I'd love to see a study stating that. Based on experimental results at our facility, overvolume due to the screener parameters have rarely caused a solder short. so, in conclusion, does one need a solde

I agree with Dave. The only reliable way is to perform a time study using a watch with decimal minutes. Setup the study using an average rated operator and time 10 component insertions (from pick up to hands off), time 10 component soldering operati

Does the machine come with manuals, training? - do you get a feeder setup jig with the sale, is there any spares to go with it, do you have any contacts for spares, what sort of maintenance is required - how often etc. did the previous owner do the m

Hello, Can someone help me, I want to setup a high speed SMT line. i have only 3 different products, and i have to change only once a week. I want to place 0402 and maybe later 0201. I think that a FCM 2 or a QP-132E are good machines for that? c

I'd tend to agree with what the others have said. Check the basics, board supports, setup, wiper paper working correctly. If it's a humidity issue, try taking some paste, place it on a chem wipe, and roll it around a bit, which removes some of the mo

After bar-coding or manual data entry the data is in the Mydata database. The data is not stored in the feeder but in the database. The database links the component data to a serialized feeder and to a PCB s/n or production batch code. The machine so

This is just a simplistic suggestion but why don't you invest in additional feeders so that you can do a 'complete' feeder setup offline? How much money is 1 hour of downtime costing your operation? If you can reduce the pit stop from 60 minutes to

At each of the machines we have a log book.One of the sections that the operators fill out in the log is called machine downtime, and next to it is a comment section.Any time the machine is not placing parts they make a quick note of why they are dow

My take on it, is that you can't exactly match labour to machine requirements. So the question is, which are you going to focus on? Keeping the machine busy or keeping the people busy. One or the other will have "waiting" periods. To me because the
