Mornin! We just had vendor in here pitching a "low-temperature rework system" which was intriguing, but too expensive. He did get me to thinking though, beyond heating ceramic caps before hand-soldering them, it seems like it would be advantag

It sounds like you will need to pre-heat the aluminum beofre using even a laser to solder this type of application. While lasers are great for many applications, especially those that have challenging keep out areas, thermal mass issues (with approp

Besides changing fluxes, do you have good knowledge of actual flux volumes? Do you have a micrograms per square value? Pre-heats can affect flux by burning off too soon and also not enough - therefore moisture hits the wave- how's your humidity cont

Depending on your application, you may need to pre-heat before Soft Beam (unless they make one for it now). Plus, very small connections seem to push it's limits. The beam can only get so narrow. Lasers are good but reflectivity can come into play

Our products are a mixed technology; with both surface mount components solder side and through-hole top side, in addition to massive heat sink assemblies. We have been using your SN100C solder in our wave solder process with Multicore MFR301 Flux si

How to calculate the delta T ? What's the allowable range for delta T value? we r not calculating this in our process, instead we r maintaining the pre-heat temp which we measure from topside of the bd. Thanks in advance

Are you sure that you are getting adequate nitrogen flow up through the cap? If your pump isn't seated properly, you may have nitrogen escaping. Also, I have two different height nitrogen bases. The shorter one does not allow as much gas to escape

Hi, We are currently soldering only connectors, so there is not that much to do. For the wave we currently use palettes as we solder PCI cards but don't want to wash. So the palette keeps the flux off the board. My reasons for looking at changing o

we worked out that the wave soldering cassettes Duratstone material takes alomst 35 degree away from the surface of the pcb, and the speed is already too slow it should be over 1.0 - 1.8 meters a minute but its now already 82 cm a minute, in order to
