Hi All, I enjoyed this discussion and applaud the quote from Stephen �following the followers�. I�m President/Technical Advisor in a flux and solder Mfg. Company and have so far resisted marketing lead-free and VOC free products, because at this poi

Rick, As I understand your comments, you do not need to clean off the flux residues? Then hot water and a little cleaning chemistry should do. However, there may be some reaction by the residual flux if not enough cleaning chemistry is used. There a

There are many factors that can lead to solder balls. Since you have just recently seen this start to occur, it is obvious something has changed in the product or your process. Since we don't have a lot of details about your process, I would sugges

Frank, We are currently running lead free for approximately 1 yr. now but no where near the volumes you have mentioned. We are about 5k units per month. I personally am in agreement with you as far as OSP. I also do not like white tin finish since

We are experiencing fracture problems with 0805 X7R capacitors. The capacitors seem to fail in tension; during hot-air rework they come apart in two pieces with the fracture near the metallization end. Only X7R SMT components are affected, C0G and Y

We are having the exact same problem! We do about 6 or so ROHS SMT builds. 5 are fine now but we had problems with most initially and 1 is trouble still. All boards are same material, same PCB manufacturer. Initially, when the delam. problem occu

Hi, if you do only contract services I`d advice own part numbering. All I can say is just try to create each cathegories which will contain other cathegories and so on. Applying this system will make some order in your stock. For instance : RETR020

Hello federico, This is Reese. Yes, you can pick up tombstoned parts reliably with the M1. You cannot pick up lifted leads very well however. I have not tried other algorithms yet, just histogram analysis which is the standard method for inspecti

Hi, We have been struggling with an issue of non wetting on a QFP (Renesas - 256, Sn90Pb10) but the issue "desapears" sometimes for a while and then back again suddenly. This is the scenario: Component: QFP 256 / Renesas / Sn90Pb10 / 0.5 mm pitch S
