Hi Dave, Thank you for your information. How about the glue print on PCB and not mount component, what is the idae to inspection this glue is suitable for mounting component. For example insufficient glue excessive glue. Because we found the problem

Rick, Do you check both side of the board after wave? Can you check the orientation of components, missing of components and also the solder joint defects? We are also very interested in this type of machine. Thanks for the information. Carol

We do what here is call a master, this board has a bunch of misalign components, missing components, bad solder joints, crack components, and other defects that we want the AOI to look for, now we compare what the AOI finds with a list of the defects

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

Q1:What is the relation between component standoff and drop missing? A1:component standoff will identify either solder paste at SMT side can form the fillet at component terminal or not. Drop/missing component is totally out of the topics since i jus

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

We want to check for missing and misaligned component. The problem we have right now is concerning modifications. When ICT detect a problem ( missing component or a bad resistor value ) we have to remove soler, do the change and resolder. It's too

Has anyone had the experience of losing components after they have been placed by the HSP 4796 because of table movement. I've worked on the 4760s, 4780s, and 4785. I don't know if this is a problem or not. We are trying to determine if this a possib
