Thanks for the input! We are doing a few protos this week and we will see how they go!

I apologize for being so vague. It is a standard leaded process using ALPHA OM-5100 for the SMT. So would a reduction in wash temp result in less white residue?

We use the OM-5100 and wash it with relatively good results. Just dont let it sit longer than a few days before wash. We've used Zestron AC200 and A-250 in a batch cleaner set to 140 wash temp for 8-10 min @ the recommended concentrations. We have h

Have been playing with VOC free water based fluxes, so far they appear to come clean in an aqueous cleaner, I went to perform Ionagraph testing but our machine was down so I will let you know if they pass ionics.

Our latest designs are flip chip on flex based and we have issues with delamination/blistering. We know it is related to our vapor solvent (n-Propyl Bromide based) attacking an inner layer adhesive. Has anyone else ever heard of something like this?

All things are possible Grasshopper. You have two choices: 1 Some no-cleans are cleanable. Talk to your sales rep. 2 Rosin based fluxes are cleaned in hi-rel aps, but not cleaned in many less than hi-rel aps. Be aware that in both instances, you

Your flux residues may be acceptable for your drain, but the solder balls won't be. You'll need to filter and dispose of the filters per your local city, county, and state regs. Either that or just boil the water off and dispose of the dry remains wi

It depends on the flux type. If it's water soluble, it should be cleaned soon after reflow because OA flux remains active after reflow. If it's rosin or no-clean (low-residue), then the only concern is the longer wait time, the more difficult it will

Water will not remove no clean flux residues because they are not water soluble. Solder paste with no clean flux should only be used when the assemblies do not need to be cleaned. That said, you can buy special cleaning solvents specifically for re
