I am having reflow issues with small 6 pin SOT's. The joints on these components still look like solder paste after the reflow oven. I have tried adjusting the profile on forced air oven. Any recommendations as what to change in the profile or proces

We have encountered what appears to be mask discoloration after wave soldering. The areas of concern coincide with the areas that were exposed selectively by fixtures during wave soldering, dominated by one date code of PCB with a slightly different

All of your response were similar to our investigation. Paste was sufficient, pcb's and parts came from several different lots run in at least 2 seperate ovens. Joints look good but the solder is soft?

That is what I was looking for. The profiles did not make much sense to me. We are getting alot of cold solder joints or bumpy solder joints.

Has anyone heard of IET (ietechnologies.net) and the wave solder machine they are offering? It's an Asian made, leadfree ready machine that looks fairly robust and I understand that the cost is close to 1/2 of what you would pay for one of the big 3

Hi Slaine, Actually, HMP Leaded solder is not complient, it is exempt only when the specific application requires this temp. Sorry for the intrusion but I am working on something very similar currently. Thanks Chris

Is there a standard that we should aim for in respect to the strenght of the solder on SMT leads? We have a customer who are testing our product by pulling leads off of pads then returning them.

We had a customer who came in to discuss a solder adheasion problem on some sub-assemblies we were building for them. When they arrived, they put a sub assembly in a vise and hit it with a hammer. I was speechless to say the least...... C

I will try with temperature 255 C degrees. The wetting force vs. solder temperature for SAC305 is more than 265 C degrees (the temperature of trials). Thanks for the advise. Regards
