Hi, just my comment, theoretically No Clean means no Ion Contaminants from Flux, but it some some case ion contamination (Cl-Br-F) could come out from raw PCBs, from Components, from fingerprints, etc. To incorporate a ROSE step in the pro

As I know, the encapsulation effect occurs only with rosin based fluxes. So if you have a PBA soldered using RA Flux, you should either wash it well, or leave it alone and it will be safe. For NC process the story is different because there�s no re

I have to disagree with you, BillyD. If Craig searches the forum, he will see that the concept of a Pbfree BGA with SnPb paste has been debated many times. You say it is fine. I say it is NOT. There have been several studies done that clearly sho

All, I have a problem on a new device that we have on a new product. It is a LLP (Leadless Leadframe Package) if you search in google "sda16a" you can see one. I am finding it next to impossible to consistently achieve a good visible solder fillet

If the OSP boards have gone through double reflow I assume that you use an aggressive (halide) flux for wave soldering. SAC 305 is known (search the archives) to dissolve copper faster than other lead-free alloys. This together with an aggressive flu

Check placement pressure. I agree with the "smushing" theory. If you can place the component with less pressure, I'd do that first. A switch to Type three paste is also a good idea, as long as your minimum aperture dimension remains at 0.009" as you

Just as an update P. Kay would not sell it until it was formally introduced at APEX. The sales rep issue in North America is still being finalized with the first rep due to be anounced this week.In the meantime they are taking orders and providing in

Hi Dougs I worked a bit a few years ago with a diode type soldering laser. I found laser soldering very application specific so make sure you send samples off to differnt companies to see actual results. You can get good results with a laser system

Hi, I off center idea we used when we started. Get a pasta cooker, and put in vapor phase fluid, and then use that. Place the product in the bottom of the inner pot, and then heat on a small hot plate. When the vapor cloud gets high enough and the
