What you have is blowholes. Baking your boards prior to soldering will help. Root cause is either barrel plating too thin or barrel cracks allowing laminate moisture to escape. Patrick

I am wondering why the PnP manufacturers are not adding more modern part packages to their databases? Let me know what types of packages you are looking for and if I have them I will send you the data, from our database.

What software are people using to compute route and retain tabs on panels? I produce some complicated (150 board, 80+ different design) panels, and I haven't found a good way to programmatically compute where to place the tabs. Thanks.

Yes, we use solder paste,solder bar and solder wire from different manufactureres for 1PCB assembly. And, what JAX said, we never mixed solder paste from different manufactures and used.

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?

What about trying to clean these stencils with a proper stencil cleaner? This way you wouldn't have to worry about sending anything airborne.

I have experienced the same issue with the repair plus software not saving or displaying images properly when the defects are being reviewed. Have you asked Mirtec about it? What did they tell you? Curious to know.

An independant analysis might also be warrented. And what I've seen is that you can't save money on PCB's. If you go with cheap providers you end up with boards that cost big time in other ways.

Hi Danny, What is your max PCB. How many board would you like to reflow per day? Best Regards, Vee
