Hi guys HELP!!!!!!!!!! I have been tasked with working out a chart to show calibration acCuracy and that my machines are in control I say to myself I know they are cause I have no misplacement of fine pitch but this is not good enough for my co

Justin, you will find measuring equipment at http://www.omega.com All sensor signals are in uV or mV and require a signal amplifier. If you get an amplifier with display, you can program a conversion factor for mV to board stretch and it will show a

Excuse me, but if I remember my physics lessons well, volume is what the water displacement measures, not mass. therefore, if you take the volume of water displaced by your populated PCB, divide it by the thickness of the PCB (which is easy to measur

Did you use the frame grabber software that is available for the LSM? I used one in the past and we also failed the GR&R we then installed this software and it became very consistant unfortubately I cannot remember who sells this software. Anyway,

I'd like to ask for feedback on monitoring the reflow oven using a copper plate.Are there any articles relating to the above, in the sense of what size the copper plate should be, how many thermocouples should be attached, the frequency of measure me

Hi all, I plan to measure the placement repeatability and accuracy. Is there any work done to simulate the paste effects on test board without using paste (My measurement equipment is a back lighting equipment). I saw someone placing components on

I was wondering if anyone knows of a tool, like a depth gauge, that is designed to measure the component count of partial SMT component reels. Most reels have a built in indicator gauge, but several do not. A tool would be handy for our physical in

Most conveyors are sold by the inch. I allow for no more than one inch gap between the end of the conveyor and the next piece of equipment. If you trust your measurements, 1/2 inch is best. This will allow for the smoothest transfer possible of small

Hello Mike, The IPC has recently released a specification (IPC-9850) that characterizes the performance of placement machines. The process is very similar to the process you describe (placing parts on a glass plate and measuring the results). The I

Hi, I can give you a few steps. 1. The solder paste. Take the profile that manifacturer gives for the paste. 2. Use termocouple to measure the tempereture. Put PCB and measure the temperature in equal terms. 3. Compare your profile to manifacturers
