AR Sounds like dirty chains... couple ways to check... Pull off the drive chain for the conveyor. Place a wrench on the (unload end) drive shaft and spin, if it is a bit tough.. dirty rails. Also look at load end of chains. The chain goes low and w

Thanks for the replies.With which ever machine we decide on the feeders with the most commonly used parts will stay on the machine. Also parts used on other jobs but not needed for the current one will be able to stay as well. The problem well run in

I am working on a Substrate attach process. The package is gold plated, the preform is AuSn and the backing on the substrate is PdAg. I am using a Sikama reflow furnace. The profile has a 50 sec dwell time. I am over 280 degees C for a little over 1

There is no standard, nor should there be [because the IPC standards should be aimed at describing results, not the path used to reach the results]. So, your printer equipment supplier recommendations are a good starting point. Your "35-46 lbs-in"

Grant has a good idea, we started that way also. We made a tank out of stainless steel with copper tube coils about 18" off the bottom. Circulate cold water through the tubes to condense the vapor to keep the loss down. We used electric burners under

It all depends on process, design and environment in which the contacts are used. Both have excellent conductivity characteristics Both don't oxidize over time On the other hand gold is much softer then carbon, and after hitting that contact a gazil

I assume you talk about wave soldering. No-clean fluxes are widely used since 1987 or earlier and after all these years they have proven to be reliable. If you clean the board or not the dust bunnies etc. will still reach the board surface. If you us

In all fairness no one has the answer for you, non of the lead-free alloys has been long enough in use or have supporting long-term reliability data. No matter what alloy you will use, your company will be at risk, that�s why so many exemptions are a
