Hello everyone, Is it possible to quantify what you consider "Low Level" vs. High Level x-ray exposure? Is anyone aware of what level of exposure the airlines typically use in security applications? Thanks, Sean

That has also been the standard here. We have a urethane line which pulls a vacuum on the mixture before transfering to the can. I plan on testing this out before receipt of the 73 thinner. I've also received some feedback with indication that the mi

Hi Ken Given the small mass of the dot I'm guessing that the adhesive is being flash cured by the heat of the board and the resulting semi-solid is unable to release from the nozzle like a liquid thereby causing your strings. Placing components on c

I am experiencing a problem with a surface mount coax connector that over time pulls loose from the PWB. The connector has 4 small gold plated leads and we are soldering it to a flash gold board. A cable plugs into the connector and puts some const

Chemical gold is a poorly defined [very sloppy] term that means various thing to different people [as you've demonstrated]. Commonly it is either: * ENIG: 5�m Ni, 0.1�m Au * Immersion gold "Autocatalytic chemical gold plating" - Refers to "electrol

Todd, All liquid coatings are Newtonian - they follow gravity so they do indeed run away from sharp leads and edges. Silicones are generally worse because they have very low surface energy - although this is an asset when trying to get under compone

I'm working on bringing up a new conformal coat process/workcenter and have a few questions I'm hoping someone might have experience with. Right now we're manually spraying both coating materials (1B31 and 1A33 from Humiseal) using HVLP guns. I run
