Hi Kelvin, Regarding to the surface finish of the leads, Sn or Pd may be the direction that the industry takes. First of all, the answer must be "Pb-Free", limiting our choices. Sn has good solderability, and it won't have too great of an impact o

| | exactly how do you access posted library articles? | | Are you refering to the newest posting by Chrys Shea on wave soldering? Looks like she did not successfully post the article. We have emailed her on this, so hopefully you will be able to

Interesting study. It shows no-Pb alloys having a greater negative environmental impact. I wonder if the Euros are re-thinking their no-Pb regulations? I also wonder if popular opinion and politics is at the route of our EPA's no-Pb regulations and n

Have you taken a look at our SolderStar range of profilers. We offer 4,6 and 12 channel versions. Our 12 channel system can also be connected to our Wave Shuttle product for wave solder machine analysis. Our datalogger are the smallest reflow profile

Straw pole time folks, how many have or are doing wave soldering of Lead free products and are you using N2 in the process, what level of solids are you using and are you cleaning? I've heard a story that soem people in Japan are running a high sol

Hi, We've got a 6622, been running since Jan & does a good job. You may want to consider the smart wave option as this will (allegedly)force solder up the holes to give you better joints for lead free. Spray fluxer works very well, limiting the am

With twenty five machines working with the LFB227/S on our little island it does seem to work well. Wetting is good compared to Tin/Copper and flow is comparable to 63/37. Biggest problem sticking 3 - 4 % Ag in a solder ignoring the patents and royal

Try a rosin flux this has solved it for me on numerous occasions, no need to use heavy rosin only around 4% total solids so rosin around 1.5% is sufficient. It is down to the plasticizers which are tacky coming out of the resist. The rosin is an imme

Most component fabricators don't properly understand the impact of soldering with pure tin solderability protection on components. Here's one that does: "The Effects of Board Attachment Processing on Sn Whisker Formation on Electroplated Matte-Sn on

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
