I am not using a solder pallet, I don't think the problem is contamination related, because these parts are on some of our other assemblies, and they're being waved with no problems. The problem seems to be mainly on our panelized boards for some rea

Hello Just wondering if anyone has done trials on how long you can leave paste (tin-lead or pb free) on a board after you have printed it before it starts going 'off'? Thanks Chrissie FYI - have searched and found the 'pasting ahead' thread - jus

Hi J, Yes, we do too. Funny thing is I was just looking at this last Friday. We call it sharing the bottom of the barrel. Typically it's just Process Engineers stuck down here, but from time to time, Maintenance gets stuck down here too. When in

Robot soldering has never really worked well and if you are looking for any volume or repeatability, you may be disappointed! Even though you are using a robot, you are still soldering with an iron and wire solder. This process cant guaranty the be

I do this ALL the time, and it is pretty much transparent to the process. We have done shake, burn in, and functional tests with our products and we didn't have any issues what so ever. We have had a RoHS complient process for well over 18 months n

Personally I wouldn't count anything but minutes. You need to know how long it takes to perform each task in order to balance your line. What I'm gathering is that you've got one printer feeding 4 machines, all running different jobs or maybe a pai

The two machines in the middle are really really old m/c's so we try as much as possible to not to use them (apart from as very expensive conveyor belts). They run a fixed set up as although we have a bunch of different products they all tend to use

Pete, Top-side temp might be an issue. What's the easiest way to check it? I seem to recall some thermal decals that we used to use a couple of jobs ago. I spoke with the flex manufacturer, and they recommended 4 hours at 250 degrees pre-process

How wide are your pads? What paste are you using? What is your board finish? Could you please post a link to the datasheet for the component? We place a lot of MLFs, both in a Pb and Pb-free process. Our standard stencil design for MLF compon
