Yukim, Just another thought (way off the solder paste trail that you've been on so far)....Are the parts similar in thickness? The 4796 and 4797 HSP's have a closed loop function that compensates for variations in component thickness based on fe

I have seen this problem on Mydata machines before. I am very sure that your missing paste is being caused by the placement machine. Check these things : 1. There is a small white check valve on the pressure side of the vacuum pump. Make sure it is

Hopefully it is just the part data a little bit off. But if that doesn't help, make sure the thickness sensor is calibrated bang on. And do the nozzle height adjustment. What are your nozzles and filters like, as far as being clean goes? I've put dow

Dear Team, We are facing open solder issue in a sensor component. Rejection rate is 2 out of 50 components placed. The issue is very random. We have tried increasing the solder paste height from 5 mil to 7 mil. The issue persist still. Differen

Please clarify, Z axis gears (Blades)? The MPM head I believe is what your are asking is driven up and down via a lead screw. The machine gets the zero point from the "HAT" tactile sensor in the table nest. When squegees are installed the blades are

Start with a load cell (force sensor), you will need one that can handle the force range you will be placing. Someone please correct me on this if I'm wrong but I seem to recall that placement force runs in the range of a couple hundred grams. Chec

| Here is a good one for ya. Our IP3's MTU will not pick QFP240's out of cavities, 10, 12, 13, 15. This is a 3X8 tray. The listed cavities are also the closed cavities that are used for tray eject. There is plenty of vaccum, the nozzle comes down

Hello everybody Lately our machine has been working pretty well, but it can’t last too long. Now, during this week’s production cycle, it began to increase the component’s reject rate to alarming levels (obviously the operators reported me when the m

Well...here is what I can tell you: I have over $40K worth of bent A12,A13,A14 tools.Yes you heard me right $40K worth. (Since 1995) Mydata used to make a repair kit to fix them but decided to quit. They tell me the reason they quit making the kit i

About the automated printing machines: They are all a little different, but the alignment part of the process is basically the same. I don't know if you have ever seen an automatic printer, so I'll do my best to explain it. The PCB rides into the
