Probably every shop on the planet uses QC-types differently. They inspect boards for us, based on a sampling plan and work instructions for that board. When they find a problem, they put a little adhesive arrow on the board that points to the probl

Not necessarily on inspection but in reliability. Do you want to ship product that will last only a few years or product that can last more than five years? X-Ray process will let you know if you have exposed your BGA's to an aggressive profile or a

Yes of course we are doing placement of BGA's with an IPII. However there is no front lighting so you can not inspect the balls. If the silhouette is square enough there is no problem with alignment. Just use the largest nozzle that will fit on the p

I cant wait to hear the replies. We are an Ersascope dealer. Have sold over 25 systems. Have looked at all the competitors and Fortunately in our minds, Ersa still offers the best system. Not the least expensive, but the best. I found that ease of

Consider: * Reducing the size of the pads * Reducing the amount of solder paste * Inspecting the print. A print with irregular form (eg, print finishes with a tail, the print is inclined or something like that) * Too long in the reflow zone * Bad ali

and one more thought about your original question, if the flux does look really strange and out of place, then inspect the reflow oven. A great amount of flux condensation in the reflow oven's cooling zone can cause crystalized flux to become airbor

We had the same problems a few years back. We complained and they came back with the excuse that the supplier of the parts had made a bad batch. They sent us a new part in exchange of the broken one. When faced with premature breakage of parts that a

We have this machine and I would be surprised if it really took all two hours for training. The machine is very easy to operate. I don't believe that Glenbrook provides "inspection" training if that is what you were thinking. We love it and it do

We are currently in the process of purchasing couples of X-Ray Machines for our BGA's. I would like to know who will be the main process owner of this process, QA or Process Engineering? What are their resposibilities or coverage in this process? Any

We found a simple solution to this dilema. We told the QC department that we (manufacturing engineering) would be happy to give them control and that we would make no changes to an x-ray algorithm or pass/fail limits without them being on site and g
