Like most things in electronic assembly, this is not astrophysics. People have pasted boards, placed components, turned the board up-side down, run the board through a reflow oven, and generalized about which components: * Fall off the board. * Don

Hi all, Having a major problem with an IC being placed upside down. We pick up the fault at AOI. We have check several reels and the component is not placed upside down by the supplier. Where should I start looking; 1. Are we using an incorrect fee

If you are using vib. feeders than the component may be flipped length wise by the following components. Components should be landing with the leads on the right side but upside down. If you are using tape feeders the component may be flipped sideway

With desktop/workstation computers I am of the opinion that they should be left to run 24/7 to avoid thermal cycling daily in order to prolong their life. I have dozens of computers between my home and business and I have had good success with this f

Steve, We use stencils for applying adhesives to PCB's, with our DEK Proflow system. Works well for us. Once in a while, we have to manually add adhesive to a specific location depending on the component height. Vary rare though. You shouldn't have

Steve: I agree. Let�s break it down. * I�d rather print paste than glue any day of the week * But I know yera �Dispenser Boy�. In that case, I�d rather dispense glue than paste. * PTH / primary and SMT / secondary is a tough process either way you

we are using convection ovens and we face the issue when changing from Pb to RoHS but also even when change top side to bottom side if the diference on the profiles needs to go from a high temp to low, we are opening the hood but we would like not to

Yes it will electrically but on the appearance side it is no good. Does it have something to do with the feeder or the nozzle?

Your target ppm in on the Juki machine a take it. So it's rejecting these parts due to the inversion? Any way to disable this. A right-side down resistor is not ideal, but it will certainly work electrically. Reese
