marking standard for .1% resistors?

Electronics Forum | Mon Sep 18 14:15:59 EDT 2006 | slthomas

Thanks Jerry. It's entirely possible that the parts that were originally kitted were Yageo so we at least have some chance of things being "as they should" on the bulk of them. Those also test out at 10.00 so we're not too concerned about them. The o

Sorry, Jerry, I was just too lazy to include the k, as in 10.00k ohms. I don't have a meter that will read out to 3 places, so something like 10.014 would read at the upper limit of 10.01. Same problem exists at the lower end, obviously.

I would get yourself a better meeter. All resistors are sorted as far as I know so if you had a good meter you could just grab a reel of 5% parts and sort them your self. I have seen the markings both ways so I would not immediatly assume the parts w

Darby, these are "point one percenters", and are all/both white on black. I think it's a manufacturer's prerogative as to how they're marked (not really a standard, but a convention) so who knows. As far as getting a better meter, I'm still waiting

Quad C Series Linear Bearing Lubrication

Electronics Forum | Tue Sep 19 11:27:29 EDT 2006 | lheiss

We just purchased a Converted 4c and I've noticed that the linear bearings have what appear to be grease fittings on them. There is also a significant amount of what appears to be automotive type grease on the slides. The X axis got stuck and I cle

Gold Plating Bath Make Up

Electronics Forum | Tue Sep 19 14:39:55 EDT 2006 | ppcbs

I have some Engelhard E-74 Potassium Gold Cyanide and related chemicals I use to make a small high concentrate plating bath for swab plating. I lost my bath mixture instructions and find that Engelhard no longer supports this product. Does anyone h

Quad 3c/4c Laser Align Settings

Electronics Forum | Tue Sep 19 18:06:05 EDT 2006 | lheiss

Does anyone know of a source for better documentation for the laser align settings? I managed to get a 1206 ceramic capacitor to measure and was working on a 1206 resistor and couldn't get it to succeed. I retried the cap and it failed again and ag

Quad 3c/4c Laser Align Settings

Hi Larry, me again. Painting the tip should do diddly because you are using laser. Your cap is probably passing because it's thicker and is just inside the range of the system set-up. Check and calibrate your nozzle alignment height settings. Input t

Spray fluxing VOC free, as operation HOURS before wave solder

Electronics Forum | Fri Sep 22 04:48:14 EDT 2006 | greg york

Apply the bare minumum amount of VOC free typically 50% less than alcohol fluxes. By doing this you can keep the same top board temperature as alcohol, its only when people over flux do you need to boost up the preheater to volatise of the water. NEV
