Hi, We have the Soltec Delta C. It works well, and is very stable. I think the software is a bit simplistic, but it keeps the wave stable, so that's the main thing. It's the timer on the software that I find annoying. It has a warm up time, and yo

I have had some field failures returned recently, the boards had flux contamination under the components in a sensitive area, Nothing really visible until the component was removed, and the board had no evidence of rework of any type. Is it possib

Been there - done that. Makes a mess on that 2nd reflow process- doesn't it!?!?!? This is caused by design. If the open via is located in the land area, it will flow thru the via and cause pumps on the opposite side. You can have your vias filled

Hello, Understand you have problem of cleaning adhesives from Dek Pump Print stencil. Well, we have a cleaning machine which able to clean solder paste and adhesives. And also, we are not using any chemical but use water-base detergent. We had few c

Hi, Thanks for the info! In the software can you add solder paste specs and heat sensitive components and see where the profile sits against these fast? Measurement is the easiest part I think, but what I thinks harder is good software to analyze th

On contaminated assemblies: While you isolated part of your dendritic growth to contaminated boards, could it be that you have a similar problem with other components, rather than your flux? Is this flux new? Have you had similar problems with thi

If the white residue is from a no-clean flux or no- clean solder flux core you can leave it on the board. (Consult with the flux or cored solder manufacturer) Because after being encapsulated with conformal coating the residue is sealed from humidity

120 degrees F (49 degrees C.), check the fine-pitch apertures for shape distortion (stainless steel has a very poor memory, once it expands, it doesn�t always contract back to the same position). Check for dings and dents. A good stencil cleaning pr

Our past experience with Frost and Sullivan is that they derive most of their data from interviews with the subject companies and press releases. That puts them a half a notch above asking the sales reps for info (except with F&S, the total won't be

Hi there Gary, Your solder ball problem is very similar the problem I experienced, but I was using a water soluble paste at the time. It started by inspectors telling me that they were seeing cold solder on some SIMM's that we had built regularly. W
