Hi all, If you are profiling a pcb that has a wide variety of comonpenents with varying temperature sensitivity requirements what do you do? e.g. 1136 ball BGA with min reflow temp 245 with tsop48 with max reflow temp 235 etc. rgd's aj

Well, I did manage to solve this problem. I lowered the max boards temp from 245 to 235. Then I decreased my TAL. This seemed to work perfectly. Thanks everyone for your suggestions! They got me in the right direction.

For anyone looking this up in the future, I ended up settling on part number "A-2-3.5", an aluminum, smooth finish coupon, 0.025" thick x 2" x 3.5".

I have two industry leading customers that have specific requirements for components to survive 30 seconds above 230C. In one case I have a custom ASIC that is heat sinked on the die (to the PCB). The sink pulls heat out of the lead frame very effi

It all depends on what type of board you need to solder. If your boards are small in size and low thermal mass and your conveyor speed requirments are normal, then I'd say the OmniFlo 7 will do the job. It has a max zone temp setting of 280C. The cur

Yes, I am currently using Viromet 347 at the moment for my SMT lines. 100-150, 35 sec 150-207, 40 sec 207-above, 80 sec peak temp: 225 deg C. It is compatible to SAC paste in term of solderability and wettability. But in term of mechanical property (

As was stated before, you need to have oven temperatures (profile) set such that you get good solder joints with the paste you are using. And definately run a profiler through yor oven to verify it is working properly. As for components, most data
