Can you run the board on the other side of the oven??? Can you turn on the oven and set the heat real low and feel the air blowing down over the heaters???? You may be able to tell something is going on that way. Also make sure vibration isnt causing

Chris (if thats your real name), For 0201 I only use Asahi from Singapore. If it is 0402 Asahi is by far the best. Kester is mainly used for 0603 and Indium is a good choice for BGA's only (and some QFP's). Just my frank opinion. Hope the infor

Most Lead Free Solder suppliers are saying that stencil aperatures should go to 1:1 or have no change from previous stencils design. Only one solder supplier seems to be complicating the process....is their solder very different?? Can anyone share st

OK...here's another one. The HiE designation began with UP-2000's I believe. And if I'm not mistaken the difference between a HiE and a non HiE was speed improvements as it related to axis movement times. If you could figure out a way to accomplish t

All, I might be going over old ground here but I would like to get some idea as to when people are planning to switch over to a Leadfree Process. I know they say July 2006 but surely we should be switching over a couple of months before this? any

Hi Danny, Buying those machines would not have been low cost - the support, programming etc. is very expensive, and they are not easy machines to learn or repair. The machines wouldn't even be suitable for the future as they won't go below 0603 (1.

i find it hard to believe that you cant get another shaft and replace it. I am sure they will always say not to do it...like every other company....but if you know the machine and if you know how to calibrate it.....I cant see a reason to not give it

I would attack the simplest possibility first. Make SURE you have enough solder paste going on the pads. If you don't, not only will you not have enough solder to make a good fillet, but you might not have enough flux available to allow what little s

We've never heard of this [but all of our gold is electroless, not electrolytic]. If the delamination is caused by the electroylic gold finishing and the via plug process during fabrication, something is wrong. Either your supplier: * Is goofy ...

I am engaged with SMT production and we are going to have a brand new SMT line and I am studing about the screen printing and I have seen most commonly used stencil thickness is 6mil and I need to know what is the best solder paste height we can achi
