We bought a conformal coating removal machine AKA a sand blaster at an auction. It is a CCR2000 especially made to be ESD safe. Does anyone have any experience with sandblasting conformal coating? We mostly use humiseal 1A33 and UV40. When we use the

Hello, I want to make a simple conformal coating machine, I think in a Cartesian robot with MACH3 software. My questions are about the G-Code for the program (the software to design: % open/close nozzle, the paths (trajectory), import the pcb fi

Re: item 3 - there are ultrasonic thickness machines (Panametrics makes one) that can measure coating dry with a small transducer head. A little pricey for ones that measure reliably in the .003" +/- .002" range.

Hi first DS65 version is a specific dilution for dispensing machine, in this case the typical process is following: application of the conformal coating extraction of solvent (low extraction power is better)2minutes and drying the drying can be done

Hi all, I need some pro help me with issue bubbles after coating. some information for some pro: Machine: Asymtek Chemical: Achime AVR80 Oven: IA 4 zoon4 ( setting 100 100 90 80 conveyor speed: 0.6 m/min). I had happened before and after the oven. W

we are using acrylic conformal coating on the PCB. Under the same program, same parameters (not changing anything on the machine), and we always found one or two boards have some spots which are not coated (shown as picture). The location of the spot

this is one of my project. I have tried to remove coating only on those areas with alcohol and thinner, then program the machine to coat the removed area again. But the result obviously shows that two different tones of coating on the board. I also

What's this 'metalic coating on both sides'? Is that like a 'two-sided board'? I expect that your 200�F is the primary side temperature just prior to entering the wave. If not, you need more juice [depending on your flux and all that]. [Some mode

Robert: Several points: 1 Dross is a mixture of various things with no "fixed" composition: � The obvious things are metal oxides mixed with metal and this can vary in color with temperature and composition - remember some intermetallic oxides form

Thanks for the input, but ken that would cost a small fortune. But wouldn't it be nice if a machine had powder coating on all surfaces?
