The PCB's are supplied by the customer. No options. The BOSS say's get it done, make it work, I don't want to hear it. My BOSS is a psychotic idiot. The printer is a DEK with no options for manual fiducial over-ride. I think my idiot BOSS wrote the

Well, it mostly does. The explanation and how-to-fix fields of the error chart do contain some howlingly bad translations. But, the how to fix field said the management info needed to be cleared. Once I understood they meant the MIS statistical dat

Hi Mefunak, I'd say that the vacuum holding circuit is at fault. If the component is picked OK from the feeder ('vacuum check after pickup' is switched on) then the component is being dropped from the head as the gantry moves to the placement positi

I made my own wave measuring device using KIC2000 system. KIC2000 has automatic wave detection, so now I have a profiler for both reflow ovens and wave solder. The delmat carrier only cost $500. A guy, Samir, from this forum gave me the idea, actu

As someone with a LOT of experience with the "low cost" alternative alloys, primarily SACX, I have one simple question....Are these shorts a new phenomena? WAS your process in control, and all of a sudden it's not? If the answer is YES, take a look a

Hi, I was just wondering what the most common process is for silkscreen/legend removal and/or rework? Scenario: Fab house had a registration issue on some SOT-323 packages where the silkscreen encroached or was actually printed on the surface pads

Hello, I am Philip Kazmierowicz and I work with KIC, a Thermal Profiling company. We have done many lifetime experiments on Printed Circuit Boards over the years. The key thing to understand is that if the primary material of the board in FR4 fiber

RC, I agree. I have tried to educate management as to the real benifits of height measurement. Our President attended a CEO meeting of some sort and was told that solder paste height measurement will solve all of the worlds problems. She then inquir

SORRY I did not offer a solution so here goes - The best way to get rid of this issue if you cant change flux is to reduce your flux consumption to a minimal with a spray flux and keep the heat REALLY high to boil off the alcohol before it can be abs
