SN100C is designed not to corrode your pot, and can be used on standard solderpots (after a proper clean out), whereas SACX is still corrosive and if the coating is compromised then could cause problems. Get it in writing from the supplier that the

Hello all, The situation: We recently had 2 brand new solder wave installed, one after the other. On the first one, the "protective coating" on the solder pot started to flake off 1 day after start-up. The tech who did the installation witnessed it a

Last april,I have seen same behavior on a pot using SACX. Phenomena happened just few days after start up of a brand new solder wave. I know they have got the pot replaced but I do not know what about the new pot if had same problem. I know they mad

Hi Simon, The main reason that it would probably be removed would be do to lack of clearance for a soldermask dam from pad to pad. typically if the clearance from pad to pad is under .008 the solder mask dam would be removed. Min recomended dam siz

The lead Wade is speaking about is not (technically) in solution. It is in suspension (or someting like that). The lead is solder balls, flakes, and the like that is offal from his soldering process. He needs to filter this material from the waste

I am having a problem with the green solder mask flaking off exposing bare copper. The mask was defective from the board manufacturer. My problem is the boards are already assembled and we are just finding the problem. Is there a standard that cover

We wouldn't advocate extending the soldermask beyond the component body but yes to ganging for fine pitch. To ensure we don't run into issues with flaking our preference is not to add solder mask when the space between pins is less than 6 mil.

We have recently started using lead free solder on our wave. The dross accumulates rather quickly. The dross flakes (tin oxide?) are light enough to sometimes fall or float into the main wave. What kind of quality concerns are there if the dross is m

Regarding nano coatings : Nano coatings are susceptible to wear during the printing process and cleaning processes. As they wear they flake off and can potentially contaminate your solder. There is not a lot of independent data available on this so k

This is a question regarding soldermask between pins of fine pitch devices. The majority of our production designs end up with at least 2-3 mils of copper thickness on the external layers due to blind vias, wrap plating requirements, etc. Our curre
