We had the misfortune of ending up with a batch of Kester EM907 that would start to "set up" well before it's shelf life was over. Since the lead time for a new batch was excessive, a Kester technical guru came to our facility to help us deal with t

Thanks for your information. What model year is your Heller 1700?. It seems that you can find same model (1700EXL) from 1999 to 2008 but there should be some differences between them which I don't know. Just want to make sure you are not running a ne

We are using a Heller 1707EXL for both lead and lead-free assemblies with no problems. The zones can reach the temperatures needed for lead free. The belt speed can be adjusted so I'm not sure about your "run slow" comment. Maybe the 1707 is diffe

I think you are close to the problem when you expect the pcb having a problem. When I look at your different pics I saw that your via holes looks like this pcb has a hasl finish... and when i look at Q 14 this picture tells me that the pcb is not an

I worked for a company that did fast change overs with Panasonic machines. We also had dedicated feeders that never came off the machine. But even with over 100 different dedicated parts most set-ups still had 30 or more parts to load. All feeders w

Hi, Does anyone know what kind of cable the thinline profiler uses? I recently acquired one of these profilers, but it came with no cables. I went out and bought a female to female serial cable, but it did not work. It will not communicate with my P

This runs up a big caution flag in my mind! Counterfiet parts are often produced by removing the original markings and remarking the ICs with different part and lot numbers. I am not accusing you of this BUT we have recently been bit by counterfei

As Mark stated in a different reply, we also send our Pb-free BGA's out to be re-balled with SnPb paste so that we don't have to elevate the reflow temperatures. You have to be careful regarding the individual components on your boards as although m

Sr. Tech I thought that was you, and have been wondering how you was doing. Any one that has been around this pcb business, if there is a business any more, knows that we all get involved in dealings that we could have done different. I do have a f

We are also having some issues with certain small parts. In our case this is tantalum caps and 0402 caps. We had a vendor admit after much discussion that the plating used from a particular orgin was different on the tantalums. The tehory is thatthsi
