I just discovered my reflow oven exhaust had no suction and I'm fixing it now. What I want to know is what happened to my process. FYI. The exhaust from my other oven was getting kicked back into the faulty oven because of this loss of suction. The

I have been using an Advantek machine for years. It is a manual load and really works good. Rarely do we have problems. When we do its because we got parts from an egineer that dumped a tube of parts out on their desk to get one part and then put the

Tony SMT, Have you looked into alternative services? I haven't performed a cost analysis lately, but with the equipment costs, tape & reel costs, cover tape handling issues, manual steps involved from someone who doesn't perform the task on a regula

Well, as usual, you can't trust ANY documentation to get it right! I have a CSM84, model PA1306/20, the last model with DC brush motors. I have the service manual for the machine, it has schematics of much of the machine, but skips the servo amps a

Does anyone use or have any simple wave/reflow oven exhaust monitors with a visual check (LED). I was going to design something crude resembling a fan with an electric winding (electric motor of sorts)and a load (resistor maybe with a transistor if

I would probably try to get my boss to spring for a digital anemometer (air velocity meter) and figure out what my velocity needed to be to get the specified airflow. Then just check it daily before production starts and when it starts to slow down,

We don't have one of those cool air compressed syringes to dispense adhesive. We have to do it by hand. My question is does anyone have any suggestions on syringe size, needle size etc... for successful deposition of SMT adhesive? I know you can go s

As long as it doesn't have a thermal pad soldered under the package, it shouldn't be a big problem. Small, pointed iron, stereo zoom microscope if you can find one, or a head-mounted magnifier. Lots of light. Rest the heel of your hand on the boar

I must ask the silly question- are you sure you deposited the correct amount of paste? Depending on aperature design-the voiding could come from a stencil that has its holes partially built up with old paste. If paste volume is guaranteed, then what

That is bizarre. I would have to say that you need to do a test on the PCB to test solderability with an iron like mentioned before. If you don't find that the pads are contaminated or masked over lightly and the pads do take solder effortlessly, you
