Thanks for that info... I found out that MPM has UP2000 HiE VP with price lower than DEK Horizon but just a bit higher or let's say relatively the same as DEK ELA...I find it hard to decide which among the 2 based on our budget capability. My budget

Dear Ing, Have you analyzed why some RF device aren't operational after washing? An assumption is that failures are related to the ultrasonic energy applied. Other possibilities are for poor rinsing, poor drying, inadequate washing on those failed

some things to consider, Is there flux on the board. are there finger prints on the tops of parts. Is the board warped at the V score from reflow Is the board shifting in the machine during inspection. These are the issues we have had with our mir

1. Is the high RH environment consistently at 72% RH and 21.4 degrees Celsius? No, over the past 2 weeks I have recorded the highest at the moment: 67% RH at 22.6 degrees C and lowest (it is Spring not summer yet): 31.9% RH at 19.0 degrees C. Or d

Hi All, I have been looking in to some failures of PCB's in Assembly. After SMT the boards are stored for different periods of time in high humity environment (72% RH and 21.4 degrees Celsius) before being sent to Assembly to be handsoldered/put thr

Off hand, I can't recall a "formula" for how long boards could sit in a specific RH environment. I've done a couple of quick Google searches, and can find a bunch of information on the dispersion rate of moisture in various PCB materials, but, nothi
