If the pendulum is motor driven, it's more likely that a capacitor change will accomplish what you want than a resistor change. You've got a 47uF in there...try a factor of 10, and put a 4.7uF in there and see what happens. If the pendulum period i

Hello, I have a problem with the solder paste process, I need a solder paste with no Start-up Time because We do not work 24 hours in the manufacturing process, we works only 8 hours a day and at the finish we need to store the paste in the refr

I built one using an old Asymtek Automove. When all was said and done, it cost less than $400, including what was paid for the machine itself. It's a very basic setup, (air over syringe), but for our needs it does everything and more. With air to syr

Hello. Several companies offer what you seek, with different options (like reel traceability, msl levels etc.) depending what you need and of course how much are you willing to pay. I worked with 2 systems - Itac (which we bought) and one custom made

When I made my previous reply, I don't think I was very clear in what I said, so like any politician I will rephrase my response to the question. My intent was that the board didn't have enough soak time leading up to final reflow. So what was happen

After looking at your profile, some general thoughts.... Your profile looks like what is commonly called a ramp-spike profile and not a ramp-soak-spike profile. Going off of Sarason's comment, you may not have a good soak period before the spike in

Also, for anyone who's taken an interest in this thread: We just received samples of Henkel/Loctite's room temperature stable(yes, you read that right), halide-free, lead-free pastes, both the GC 10 and the GC 3W (which is a water soluble/wash paste

We have had some test results come back after we were getting poor wetting in our joints, we requested an EDS on our joints from our PCB supplier. They have provided the results and said that it was their fault and will replace. What I want to know

Are your PCB's stretched or is it that the films that were used to make your PCB's distorted.Thus vias and TH's don't align. These things will probably be picked up in bare board testing , but depending on the amount of offset may get through, to yo

Hi all, My company recently purchased a preowned EBSO SPA 400-F, and I am trying to get it up and running. Still need to get a few other parts like a nozzle and nitrogen generator, but in the meantime I was looking to clean out the residues and oxid
