Hi Basem, We are seeing a lot of our customers buying M2's & M4E's, and they are very happy with them. These are intellegent, profitable & well informed CEMs in the main, and for the money there is nothing else new that competes. Depending on wh

Hi Basem, The people I know are placing BGAs & down to 0201 with no problems. However the best thing for you to do is get them to demostrate placing your component range, and if you go ahead, draw up a machine acceptance document to form part of th

Thanks Rob. Our concern is placing tiny components side by side at a minimum pitch, along with fairly large BGAs and TSOP2, which are themselves, having small to fine pitch leads. yes, accuracy in placement in our application is crucial, yet, what i

Hi Basem, Juki have been around a long time - at least 15 years (formally branded Zevatech in Europe) & have a very large instal base. Their machines are good quality, but a little pricey. I have seen a number of them working with no problems in T

We've got a problem with our AP25.. I just finished repairing and calibrating this printer. We needed to replace the camera. After the cal. was done, the print accuracy was superb. However, it seems now, the consistency will not maintain itself. T

Dax, Just an FYI....we have had AP25's for years. I have never had to calibrate them. Also, I am not a MPM service guy but I would have to say that if your standard deviation numbers are coming up less than .001" you are doing ok there. Sounds to m

Hey Guys, I checked the histogram...it doesn't look good. I'm assuming the graph for the black bars has to be in the green on the left and the graph for the white card needs to be in the green on the right?? Anyways, I can't find a "GS4 pot" I looke

ARGGH! I've verified proper airflow, made sure everything is tight and secure, cleaned and lubricated the bearings and nothing seems to help. first few boards are nice...then the next few are really bad..then they kinda get good again. I have no ide

We are currently experiencing some MCSB's on 0603 components. I am looking into experimenting with the stencil thickness from 6 mil to 5 mil and also using Radiused inverted homeplate ( 20%60%20)to eliminate or reduced this problem. We are using lea
