OK, you may be using this forum for your political rants - but if not, I will appease you one more time: Issue one at hand: Blame a political leader for my mistakes. I wish it were that easy. I'd blame Oprah for my top side wetting issues. Issue

So what happens in this hypothetical model when the customer provides you all the data you asked for and then your programmer finds out that it is the wrong revision data or the BOM is truncated or the centroids are missing refs, etc... Then new data

We have evaluated vapour phase in the past and was very impressed on how simple and easy it was to use and control. Gods send when being pushed in an audit because so little can be changed and will work within the chemistry within the unit. I so want

Wave set-up DOE * Immersion depth [1/3 to 2/3 of board thickness] has the least impact of any variable in wave soldering. * Contact length the greatest impact. * Control flux density, time through preheaters, top side temperature as the board reaches

Hello federico, This is Reese. Yes, you can pick up tombstoned parts reliably with the M1. You cannot pick up lifted leads very well however. I have not tried other algorithms yet, just histogram analysis which is the standard method for inspecti

When looking at surface mount equipment you also have to remember your line pull process. Wil you issue reel of parts or just strips? Most of the bigger machine cannot take strips of parts. What about your set-up? Will you have a dedicated top an

You are on the right track Ismir. Essentially however, as the programmer of the machine, I am the one that creates the PCB with the errors to benchmark the settings for the machine. No secret lab though! :-) Easy enough for most any AOI machine to

Q1: You say that 0.008" of "slop" is un-doable; hence, the reasons for our failures. Any basis for that statement? A1: We're not even considering the accuracy of your placement machine. We base our comments on the gap between the hole and the connec

Hi All, I am using COB on my DOUBLE SIDED PCB. lastly we used Eletrolytic Ni / Flash Gold Plating. Our Boards vias Failed the UL corrosion Test. we did some cross-section analysis and found 10.75 �m of Nickel and 0.022 um of Gold and as the Process
