I've been having some problems with my Quad 4C, it rejects some components after having pikced them up. I want to adjust the tolerances and test the pick up. I want to know if there is some way of testing the pick up without having to run my whole

I have been using my topaz X for about 4 years now and I feel that I am fairly knowledgeable about it, at least the functions of it that I use... I am trying to use the LCS to place some qfp chips on a new product and I have set the whole thing up t

Ahh, yes. Just about the same time you replied someone else I asked said the same thing! I didn't realize that you had to put the part on by hand for the vision test. In the book it says to leave the feeder position set to the default setting. Fu

Not sure what you mean. 0201's and 0402's are both on 8mm feeders. Juki's will do simultaneous picks an all 8mm feeders no matter the component size. Your feeders need to be maintenanced and calibrated to reliably pick 0402's and 0201's. I hav

Thanks Sr. If you have zero tolerance for simul pick up in your component files then you will not have simul pick up due to variances in your head offsets. So you are saying that on your Juki you run a tolerance for 0201? All other head positions at

Dear Forumites, It's been a while, but I have a question. I was recently asked to provide a scenario on capacity if we retired two older lines and replaced with a new line. My capacity figures were based on real time production over a period of six

Darby, I'm not completely sure I understand. Juki machines have what is referred to as a multi-head. The offsets between the heads are the same as the spacing between 8mm feeders. So the (6) heads all come down at once and "gang pick" from 6 8mm fee

We have Samsung and havehad no problems with simultaneous pick ups with 201s 0r 402s. the feeders are durable and do not need much repair especially the sm feeders. The SME feeders have not been out as long so we will see so far so good. As with all

Sorry for delay - been flat out. Sr - I understand what you are saying. My concern is that combined with the head offsets and variations in pick points (i.e. having to teach feeder positions for very slight amounts like 0.05mm)then you cycle times wi
