We have tried solderability testing using an agressive flux and have had good results. However, our Mfg process uses laser soldering equipment which is a validated process and we are limited on the type and amount of flux we can use due to ionic cont

The smallest particle sixe for type 3 paste in 25 microns. This is far to big to remain airborne.Therefore I would suggest to continue to use air to clean stencils as it does clean the apertures effectively.What solvent is used to clean the stencils?

I am trying to decide what type of no clean flux I should use in our selective solder machine. We run both leaded and lead free and would like to use the same flux for both. What is everyone else using? Or do you have any recommendations?

Can you use trichloroethylene to clean boards? Yes Should you use trichloroethylene to clean boards? NO!!! Don't use trike. It is an environmental and a personnel health hazard. What are you looking to clean from your boards?

DeanM, if I understood correct, you use fiducial with dimension 0.1 mm and increased it to 0.15 mm. Why use use small fiducials? You don't have free space on your PCBs?

We used to use Butyl-glycol then I ran out and someone said it was no longer available. or maybe it was cheaper without it. After you use that you clean off the Butyl-glycol with IPA (Isopropyl alcohol)

We using nitrogen only for Selective Solder machine, you don't need it for reflow oven, to improve solderability we use Vapor Fase oven.

What we have found after using the machine for a while is that its difficult to set up most odd / uneven parts. The best way we have found is use the trimmer package and then use the rough check feature, that seems to work well with most things.
