HMP can mean a lot of things, although it is normally used as the generic name for one of the following alloys: Pb93.5 Ag1.5 Sn5 (296°C-301°C) Pb95 Sn5 (308°C-312°C) Pb97.5 Ag1.5 Sn1 (309°C) If you are talking abou

Hello, I am not familiar with Inertec but have some expirience with selective soldering process, My oppinion is that the wave and slective soldering are not the same game. In Selctive soldering process is very important the layout design. If use th

We theorize a secondary [bottom] side BGA can be wave soldered with planning. Issues are: * Keepout between the BGA and one side of the board that is clear of PTH parts requiring wave soldering, so to support the fixture. * Keepout around the BGA. *

I have tried to solder sockets by reflow machine. but, failed because sockets were deformed after reflow.Has anyone had some advise for me?

This socket supplier never expected you to do what you're doing to his/her part. Some materials bear-up under the thermal strain of reflow solder than others. Try different socket materials.

Thanks Davf that socket we couldn't change since the customers supply these sockets.we can contro only our process.

i agree, with the other fellow, check the data sheet for the part and see what it can handle otherwise hand assemble.

Yes. Reflow soldering PTH components goes under different names. * SMTnet's friend Bob Willis popularized the "intrusive reflow soldering" term. * Jim Blankenhorn, another of our friends, and others popularized "pin and paste". * Still others use

If the copper on your PTH is not one thou, you will get blowholes. With the cost of copper going through the ceiling, you will get less than one thou of copper plating from substandard suppliers. Consider baking your boards prior to wave soldering

I'm not a Wave soldering guy and my friend have asked me a question on what is the best preheat time and temperature for Wave soldering.They experiences only 10% flow up thru the PTH barrel. I've asked them to increase the temperatue to 120 Deg C. Cu
