I'd have to disagree with the Electrovert applications guy. I'd recommend SLOWING down the conveyor between .5 to 1 FPM - effectively, you're REDUCING contact length (because contact length = dwell time * conveyor speed), hence getting better peel-o

| We have a Vitronics SMR400N oven and many times need to use N2 inerting. My problem is that it takes close to an hour of operation to purge the system to achieve the desired O2 levels (~40PPM). This is not only time consuming but results in an inor

@Alexei Shkolnik Ah, I hope this doesn't become a problem. But if it does perhaps we can redesign the whole system? Push the components with a pusher that's connected from above rather than pulled by a magnet below. Perhaps the pusher can still clim

Hi It is very interest topic on building a AOI internal.(10000) I am very aggree on Machine designer point of view. I had gone throught the state of develop a post reflow AOI which complete it begining of this year. Just share part of it. Few poi

Hi All: Can you tell me specifically if you converted an exiting product made with Clean process using WS609 or compatible to 'No-Clean' process. We have to convert assemblies from current clean process at a CEM to No-Clean process in our own factor

| | Hello: | | We are using a Heller 1500S reflow oven to solder surface mount parts. Just within the last two weeks, the larger I.C.'s are moving while going through the oven. The parts are checked for placement before putting into the oven.

I am not a DEK user but have some knowledge of the ELA to share. The ELA has some structural differences with the Horizon and Infinity models. It is DEK's low-end automatic printer (a cost-reduced version of the Horizon model)and is manufactured in C

Dave, To tell you the truth, I couldn't tell you. I came into this company with the system installed. When the resistivity is depleted, I call Culligan. It may only be an in-line cartridge filter that they change. We've noted a change in water q

| Does anyone have angles on how to reduce N2 consumption at reflow process (i.e. process control equipment, etc.)? | | Any help would be appreciated | There are a number of ways to reduce consumption: 1)One way to look at consumption is to view i

At work we use a system in which every customer uses a part with a phantom ( top level ) part and then under that we have more part numbers that are valid. So something like a surface mount resistor would be stored as something like. PPPPPPPPPPPP
