The large copper pours in the vacinity of this part make it essential that you get your thermal recipe correct. You may need to slow down your conveyor [decrease the ramp rates] in order to minimize the effect of the board has on the different heati

I'd thought that the solder on test pad can benefit our ICT,but in fact,the residue issue arised.I'd like to know how do you test your OSP board? Thanks Bryan

pete, you forgot the board flipper and the same line duplicated again for two sided boards! and how about an Xray machine after each oven in case the flying probe cannot test all lines?

I've been trying to find the metal composition of various lead frames. I keep reading about Cu-EFTEC 64T but can't find any info on it. Does anyone know what material this is?

it can adjusted per the machine and your boards, Not a fix for every board, also if you are talking about the LF wave soldering process, it should be moved to largr angle compared to the tranditional sn/pb soldering

I need some advice on how to run a test with some large boards through the re-flow oven. The boards are 17"x17", 3/16" thick. Withought destroying one of the boards, how would I go about getting a good temperature profile?

Doug, If you are worried about cooking the board. Take a know profile and either reduce the heat in each zone or increase the belt speed.This should keep you from cooking the board. then adjust the profilr to the board from there. MrMaint

Let's not be hasty about the BTU, the Pyramax consums even more N2 than the Paragon that it replaced by something like another 40%! and the Electrovert aint that much better although it's been a while since I looked at them.
