Hi Danny, Which part of Malaysia are you located. My company, Uniwes has an entry-level X-Ray machine which has a price which will not burn a hole in your company's pocket. Please advise me . Rgds, Marshal

It is great for single sided boards, but you will have to use a glue/wave process or something else for second side assemblies. Russ

What happens to the flux and pads on the second side of a double sided board during the first reflow? It seems to me like the solder would dome and the flux would be used up and migrated to other areas. Russ

Hello! My problem are solder balls in normal (with Pb) wave soldering proces. Balls appears between connector pads. I tried to change fluxes and preheating in machine (and combinations of both). What else can I do? I have no wide experience in solder

In my normal Pb process,we 've a station names "Remove the solder balls and clean the board",I think we'll also have such a station in our Pb-free process. Bryan

If you like to absorb the cost of removing solder balls with SnPb, you will like it an even greater amount with Pb-free

what type of flux are you using and what type of solder resist is on the PCB solder resist (Gloss or Matte), also what is the orientation of the connector to the wave flow and what is the pitch of the leads? Russ

Regarding Lead Free component finishes, vendors are zeroing in on matte tin plating as the finish of choice. What test are performed, to determine if a finish is "matte" type (vs. non-matte)?
