The ISL12020 real time clock comes in a 20 lead DFN, and includes a 32kHz crystal in the package. The terminals of the crystal and oscillator come out to external pads and are highly susceptible to leakage to the neighboring power supply pins. With

We use no-clean sac305 pastes that are not water soluble. Will a DI water based washer work for cleaning these stencils or is alcohol required?

Hello. I would like to know the difference (if any) between water soluble flux and test socket cleaners (e.g. for Burn-In Board test sockets). As far as I know, they both remove oxides (tin & copper) with an activator, solvent and surfactants. Tha

I'm not familiar with any "test socket cleaners", but I will tell you that water soluble flux is designed for a soldering application so it requires heat to activate. Not sure how effective it would be at removing oxides at room temperature. Second

Thanks for the tip!

Thank you caurbach. I'm actually not sure if they are cleaners specifically for test sockets or they are just generic PCB cleaners.

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.

What flux are you using? We use a low-solids No-Clean water-based flux. Maybe some of what you are seeing is not residue from the flux but is from reaction with the solder mask.

What kind of flux you looking for water based, alcohol based, or solvent based
