For everything you wanted to know about waterjeting, look here: http://www.waterjets.org Goto page 9 of the 'picture pages' for some chopped-up circuit boards. There is at least 70 equipment suppliers out there. So, having someone that has cut th

Immersion tin, if it is being correctly identified, is not a final surface finish for a bare board. White tin is typically the way a finish is refered to. Either way tin has gotten a very bad reputation via a couple satellite failures because of tin

Get them both to prove their placement rates & accuracy on 0201's, and also guarantee that the machines will achieve this in production. Also get them both to give you a guarenteed placement rate on your most common & difficult boards, then you ca

Currently I am using a water soluble solder paste and no clean wire solder. For awhile now I have been pushing to switch to no clean across the board. Can anyone give me an idea of how this will effect production? Switching to no clean will allow m

Thank you PWH, All good points. I use a semi-automatic printing process not a screen printer so if more solder balls and beads are created then I would be creating more re-work and that is exactly what I do not want to do. I guess the best thing to

Take some of your boards along & run them. Try the same with the other alloys and see which suits your products best (make sure you make a note of the fluxes being used, and if the machines have similar preheats, nitrogen etc than yours).

Hi smtspecialist (man I gotta get me a name soon), NO! Your oven cannot contaminate your process. Unless you have flux residues dripping on your board, there is nothing to worry about. Now having your operators switch from leaded to lead-free smo

The temperatures were measured on the board, ~1/2" away from the components in question. Admittedly the profile is on the bottom end of the Alpha recommendations. The profile was set up this way intentionally to avoid heat damage to other components
