On the printer alcohol always worked way better than water. If you talk about after job is done, most stencil cleaners work with some solution/saponifier and DI water.

| Very shortly I will be evaluating OA flux and aqueous cleaning to replace our RMA and solvent cleaning process. I am primarily interested in batch aqueous cleaners for reasons of budget, floor space, etc. I am concerned about the ability of H2O t

| You may want to rethink using an inline for both OA and No-Clean applications. Since the majority of your applications are OA, it would not make a lot of economic sense to run saponifier in your inline for a minority application. My suggestion is

Yes, it is quite common. Does it [refraction] provide adequate resolution? => Depends on: * What you mean by �adequate�. * When during the process [cleaning solution life] you make the measurement. Is the [refraction] measurement affected signifi

Naw, alcohol and solvents won't do dip. Hold-off on: * Destructive testing. [Athough this will convince you to move on to other things.] * Rework of the solder connections. [Although this will correct the problem.] Consider investigating your aque

CAL, Thanks for the input. When I said chemistry I was refering to soldering chemistry and not cleaning. I believe this machine has the capability to incorporate a saponifier but would prefer not to run in this manner. Running a closed loop DI re

You can buy a titrator (Hach [ http://www.hach.com ] digital titrator), hydrochloric acid, phenolphthalein indicator powder pillows, turkey baster, and a couple small measuring cups. Titration measures quantity of TOTAL alkalinity. So, it measures

HASL Fluids are generally not RA based fluxes. They are generally fluxes based on hydrochloric acid or hydrobromic acid or a mixture of the two, plus some very strong wetting agents that are very hygroscopic. Doesn't the residue of hydrochloric go wh

I'm currently working for a OEM that has 700+ stencils in house and we received 30 to 40 stencil a month. We recently switched to a no clean process which is causing the stencil part numbers to disappear from the stencil frames due to the saponifier
