Stencil thickness = 175 microns? If my math is correct, 175u=0.175mil, and if that is english units then it is inches. I'm not understanding this correctly, please clarify for my sake please, are you saying the stencil thickness is 0.000175 inches th

Not much activity here in the past few days. Just wondering if you all have been egg nogging it too much in preparation for jolly ol' St. Nick. Or could it be that some have taken to smoking the mistletoe? I hope DaveF. has recovered OK from his re

I concur with Dave.....I have done this often with little fall out. After rework reflow we would x-ray just to ensure an acceptable joint structure. Just for curiosity sakes....are you removing a defective BGA and replacing with a good one? Site pre

Todd, for the sake of the forum could you please spell out a few key line items about why you state the Juki machines is Junki. Clearly you are unhappy with their machine. The best purpose of this forum is to identify problems with machines, proces

Dave, are you telling me that yer tryin' to pawn that off as a superscript "degree" symbol??? Wass' wrong with 183C, fer criminy's sake? (fighting urge for more defensive ranting) I'd swear a couple of old posts changed the way they displayed after
