We do not know how your KIC2000 calculates slope. Here's an approach to calculating slope: * Subtract the lower temperature from the upper temperature. [Temp|upper-Temp|lower] = Temp|change * Subtract the time when the lower temperature was measured

Hi, It really depends on what your measuring. If it's water, then that has a specific gravity of 1, so with the metric system 1 Kilogram of water is equal to 1 liter of water. That's nice the way they did that. The conversion from 1 US Gallon to 1

M, The paste height is what you establish it as. You're probably using a laser measurement system, and these depend on where your reference datum is. Some will measure from a silkscreen, a trace, or solder mask. These add height, not to mention H

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

Here is a useful website that defines Cpk: http://www.itl.nist.gov/div898/handbook/pmc/section1/pmc16.htm For placement equipment, the manufacturers typically give you a glass plate, where the intent is to measure how far off the centroid you are

�Another direct measurement to determine resistivity values (i.e. of remaining no-clean residues) can be performed through impedance spectroscopy. The surface resistance underneath chip resistors and capacitors can be determined to show the improveme

Now knowing that its a Quad, I'm assuming it has QuadAlign which spins the part it just picked in a beam of light and a sensor measures the length, width and height of each part. If it falls outside of a defined range, it will throw it in the dump bi

The only way you will be able to measure it is to count the reel before you put it on the machine, count them when they come off and deduct the amount expected to be placed. you will then have the result of attrition on the machine. or.. Pick the p

Start with targets based on the stencil thickness (for height) and stencil thickness times the aperture size (for volume). * Set reasonable upper and lower control limits (+ 25% and –25 % of the targets, for example). * Next, check the printer set-u

So, I haven't used my Quad 4C for a while and when I started everything back up to run a new board it appears that the Quad align is in need of calibration. When I pick up a component and do an LAE measurement on it it shows the part center location
