spacing is very tight but you should be able to get it right... If possible try and run it at 45 degrees over the wave and see how you get on... we had a similar problem and this improved things dramatically ( but we had a selective pallet that wa

Yes, 45 degree will kill the shadowing effect. YOu can also consider the teardrop on its land. No need to tilt to 45 degree.

Try a simple solder mask. I use Chemtronics. A bottle is only arond $20 and is as easy to apply as it is to remove. A cheap, quick fix.

Grid-lok or Quick-Tool work extremely well. There's no putting stuff together. You drop them in and go. Problem with templates is that you need to update them with rev changes. If you run hundreds of jobs this can become a nightmare.

I too would go with something like the Grid-lock. We use Red-E-sets from production solutions. They are similar to the grid-locks but don't use air.

There were some issues with the older grid-lok systems that have been resolved in the newer designs. We run them in all of our printers and Fuji chip shooters. The only issue we see is that the air pressure may need adjusted on thin boards.

Very good practical solution from Darby, I was going to say sample board or picture. in the old days we would have a board with location marks Bob Willis

Are there any established acceptance criteria for contaminants based on Ion Chromatography testing? I've found some references to certain levels for some contaminants but there doesn't seem to be any industry consensus. Any feedback or reference to l

J-STD-001E, 8.3.6.2 states 1.56um/cm2 NaCl value.

edmaya33, you're correct about what J-STD-001E says, but recognize that the measure that you refer us to in not IC [Ion Chromatography]. It is modified ROSE [Resistivity of Solvent Extract] ... or whatever they call modified ROSE now-a-days
