I have modules that come with a 4 x 2 pin header. The problem is the pins must be oxidized as they do not take solder (no wetting occurring). This occurs whether solder in our wave soldering machine or soldered by hand. I tried cleaning the module i

I ran those KE750 & KE760 machines more than 5 years ago. As I recall, it can do some sort of gang pick, just not fully simultaneously. It picks with one head first then, it picks up with the 2nd head with minor delay after the 1st pick.

Hello Bobpan, Thanks for the suggestions. Sorry I didn't reply yesterday as I'd gone home - I'm in the UK, so I'm guessing there's a time difference. Okay, I found the control to turn off the vacuum verify - it's SHIFT - SWITCH/VERIFY. Makes no di

We have both DRS24 and DRS25 here. I think you will be much happier with the DRS25 as the underboard heating is superior, of course after a year of using the 25, it has its caveats as well, though minimal. I was a little surprised that you are havin

Try these things: 1. Do a function 30....your nozzle height should consistently be around 200 +/-20....but whatever number it does find it shouldn't change. (with nozzle on) 2. Most times its the z-bellows....an old z bellows that has a worn out spri

Hello Bobpan, Thanks for the response. 1. Function 30 gives me a consistent 182-185, even after nozzle changes. I can vary this by changing mod code 15 and I have been advised to aim for 90-110, but it doesn't seem to make any difference so I've go

It sounds more as though you have a profiling problem primarily, however, if your placement is not square to the board, then you should get your machine setup correct first. After that you can get to the profiling. If the BGA is brought up to tempe

Hi Guys, I have Juki PnP machine with 2 heads, and for some reason, whatever I do, I can not make the machine to use 2independent feeders for parallel picking up single component reference by both heads from 2 feeders. Example , imagine you have a

Hi Thomas, Seems your machines do what I am looking for. Slight time delay between 2picks is OK,( because the software is not made in multithread way), that is OK.....I just want to have 1x definition of the component in placement data and Component

Hello All, I've just bought a Quad 4c pick & place machine. It's so close to actually building boards, but just doesn't quite get there. I was wondering if there's somebody out there with experience of these machines that might be able to help...?
