Did you try changing spring on the feeder? Maybe you need board supports?

If there is damage of the glass coating or exposure of the resistive element it is a defect.

I think between us we've not missed too many points...

What type of machine? Usually the service manual will have calibration intervals recommended.

Missing and misplaced components could be down to board supports set too high or too low. Check the ZO and make sure the deflection is set ok at various points across the board. Check the other usuals such as sticking nozzles, correct size nozzle for

This may be a little too late, but ever heard of a missing "silver". Had one one time (missing ground plane)and wow look at those TANT caps explode...might need some safety glasses! If they are all open look towards the design a little closer just

Hi Folk, i am wondering why they are Missing ELCap and ELCap being totally shifted out of the PCB Copper Pad during the SMT Reflow. Recently we have encountered some boards with the above mentioned symptoms. Appreciate if anyone could advise me. Th

Interesting, thanks for the info. All that I know right now is that running the jaws through an "el-cheapo" demagnetizer was one of the actions taken that resulted in a reduction of missing components. It is possible that this is not a dominant fac

If the component "fell off" sounds like double sided reflow - which is most likely a profile issue. If the parts just don't solder, could be many variables. I've had supervisors accuse ovens for bad profiles cuase they had missing parts. Too bad

I want to check this becuase we are exporting the PCB & there is problem of components missing at customer end in some PCB while we are doing 100% AOI & then ICT testing. These components are checked by both. there is no possiblities that the compone
