Make sure your reflow profiles are the best you can make them. You will probably want to, at the very least, get some sample BGA's and boards to sacrifice to profiling. Drill a small hole through the board into a middle ball of the BGA. Also put a t

Do you have an automated line with pick and place equipment that can handle your BGA's? Inspecting the board is a must after profile development. You may send the 1st board to a CEM for X-ray inspection. If you have a consistent process (printin

Goll dang Guru, I didn't win any money off of you yet but keep up the good work! I didn't know you were pushing a process that converts coal into carbon monoxide and hydrogen! Amazing! Keep up with your seven dollar words. You are a funny guy! By t

All data loggers will be warmer at the higher lead free temps. Only two ways around this... better thermal barriers or fans after the profile to cool it down. Some places do not allow fans on the production floor due to static electricity, in that

I used 1' of McMaster part # 8821K6 (0.110" thick). It is rated to 600F. I believe I put four layers over my profiler but I'd recommend starting with two. If you need more you can add it. Make the sock good and tight because the fabric seems to h

I know it's friday afternoon, and it's actually hot for once in this country, so my brain may not be working properly here, but isn't 30 micro inches of gold about 0.75 Microns? So that's dead in the middle for gold plating thickness (like gold finge

My company also uses the TM8C (all feeders) with the same problem as Paul. The 0402's do exactly the same as he desribes.The SMT operators are correcting the placement data all the time when using 0402 but to no avail. Chris What do you mean by the

So Ev, why did you just respond to a question that you admitted not knowing about? is this not the same? ie... nozzle set error, you know this could be a software conflict error as well? You answered as if it was an inspection error, when I did no

Hi all, We are running with SACX in our Wave. To be honest it was like a drop in replacemnt and we have seen some boards improve believe it or not. we find that running it at an elevated temp. i.e 280 on our selective pallets improves wetting and
