what type of solder paste are you using? Why the concern over wetting spread to the edge of pads? Are the solderjoints formed correctly at the component? Russ

don`t we have any article about the manufacturing of high frequency board . and precautions that we should use ?

Smt paste= SAC305 Wave Solder= SN100C no real problems with either of these. good luck

I agree with James. Granted there are a variety of lasers to try, we too could not get a consistent power setting. Plus when paste turns liquid, you get some reflection. Also the mask around the pad has to be pulled back or burning may occur.

Shy You should try SMT-5. First solder PTH comps, then apply paste with your pick and place and apply glue with ur screen printer and come back to place smd with pick and place and then reflow. You will get great results. Good luck

I've done a couple fiducial transplants from populated boards to non-populated boards in the past. I've also used a soldering iron on irregular shaped HASL fids to round them out. And that is a vintage rant.

this is a two row connector that I'm talking about. We were going to select solder it or wave it but we are just trying to make the process faster and if I can get this to work, it will definitely save time for us.

With two rows, you can overprint to the outside to make up the solder volume. It's when you have rows in the middle that things get tough. A good stencil house should already have overprint libraries for this.

Looking for a thru hole part that you can solder a wire or leaded part to. I remember using them in the past - but the name escapes me. It had a forked end that the lead would fit into. Any help appreciated.

It really depends on several things. Is solder paste inspection driven from the customer? Do you have a lot of time and bodies to do solder paste inspection? Does it add value to your process? If you answered �Yes� to any of the above, then you a
