As with noclean flux, OSP will fill your probes with crunchy [maybe gummy] stuff. Consider: * Increasing frequency of probe maintenance * Talking to your probe supplier about alternate probes that self-clean better

I am processing PCB's that have an n-tech osp coating and am finding huge inconsistencies in wetting. Some boards process clean with good wetting and the next has terrible wetting. The boards are stored and handled properly. Has anyone had this

Does anyone have wave solder experience using OSP and VOC free no clean flux?

Is it your normal process to wash all your bare boards or is this in response to something abnormal? Seems like something your suppliers should be taking care of, especially with a non-washable treatment. In answer to your question, I have no idea!

You weren't specific about the OSP that you use. We use Entek Plus CU-106A. Yes, just about everything removes Entek, especially if there's heat involved. Ethone states: * Alcohol strips 70% of the coating * Water removes 15% * Kyzen Lonox only t

We have begun using a PCB with Organic Surface Protectant. We normally run boards with non orgainic protectant. We can wash these boards with our ultrasonic cleaner using Zestron SC202 and a separate Hot/cold rinse system with an air knife. This r

We are using OSP coated boards and no-clean solder paste. In a few instances, we are seeing increased distortion in an audio circuit. Has anybody seen or heard of surface insulation resistance (SIR) decreasing after reflow on OSP boards? Is it possib

For 1,27 mm Column Pitch, we set our process like this: - Stencil 0,20 mm If allowed also for other SMDs otherways some time 0,150 with step up stencil used only for CCGA area. - paste height min 0,175 mm - aperture 0,75 to 0,8 mm - paste volum
