I would go with AOI. Reasons are: --AOIs are faster --They have more coverage. Given, you cannot test the value of components, but the AOI will ensure that all resistors are correct, orientation of ICs are proper and components are present on the

Michelle, It's been years since I worked on these machines and mine were CS400E's. The next time this error comes up instead of powering down Unplug the RS232 cable that links between the PC and the processor board in the machine, I cant remember if

Hi everybody, I am here seeking your experience and asking your help, I want to update our SMT production line as I already hace FUJI CP6 and QP242 machines beside GL2 and oven our new product including 60 components 0402 (1mm*0.5mm ) and 2 BGAs w

First, I would inspect for lack of solder bridges from the center slug to the outside leads. I would then look for evidence that the solder paste has reflowed beneath the component, without leaving too much void percentage. Typically we allow up

It is pretty hard to wave solder fine pitch parts bad enought with 0.5mm let alone 0.4mm It can be done but need N2 inert wave soldering & need layout design to accommodate this... Iy it is a QFP need to run part 45 deg into wave and if possible in

Hello, I am having a problem with HASL PCB's after it comes back from the stuffer. To me it looks like oxidation and it causes poor wetting. This leads to a bunch of problems all of which have different symptoms but the cause is this oxidation proble

The only thing I see that might be a fuse is the green vertical axial leaded component next to the third from the bottom white 4-pin header. It's labeled ?718 or 710. I don't know if this is a resistor or a pico fuse. You can try to ohm it out. An

assuming Sn05Pb93.5Ag1.5 Without knowing what you are trying to solder, PTH or SMT, the time might not be that far off. Does that time include stripping, cleaning, plating the leads prior to soldering onto the board?... pre-tinning the board as well
