Programming Mydata

Electronics Forum | Fri Nov 06 16:20:59 EST 2009 | 11562knott

I've speced in CircuitCAM at 3 different company's since 1996 and wouldn't use anything else. When we program our Mydata using CAD data within 5 minutes we have a program + a couple more minutes to verify the color visual aids by station. When we rec

Can anyone help me get this MPM AP27 going?

As mentioned previous, check all fuses & breakers. In the AC chassis (should be under black cover beind front, right door), remove cover and check main circuit breaker. Also should be two fuse housings next to breaker - if they are lit up amber, th

Large Footprint Flex PCBs

We do continuous reel-to-reel flex circuit PCB's with a typical "panel" width being 12". (The PCB pattern repeats every 12".) We have done some product that was 24" by doing one half of the board then the other through the screen printer. We have

Pb soldering to Pb free finishes

Electronics Forum | Thu Oct 01 16:56:40 EDT 2009 | gplume

Does anyone out there have experience soldering with Pb solder (Sn 63 or Sn 62) to SAC 305 coated PCB lands (about 50um) or Sn-Cu plated lands (about 10um). I know soldering Pb free (Sac based soler) to Pb/Sn coated lands is a no-no, but was waonderi

Thanks for the input. These are 80 pin fine pitch connectors on arrayed flex circuits. We have found from experimenting there is really no good alternative but to use local fids. I found what I'm doing wrong - I needed to move fid finds and correc

Hi, We already export in plain ASCII format with the PCB dimensions, coordinates of all 4 corners with respect to the origin, circuit repeat offsets, and Centroid data with RefDes, X, Y, R, Part No. and Package information. However many customers ha

H1N1 Hand Sanitizers and PCB contamination

Electronics Forum | Fri Nov 06 11:39:17 EST 2009 | 14367

As you know, the H1N1 virus is on the move, and we are trying to take precautions. We wish to use a 60% alcohol based lotion for disinfecting our hands. It has been questioned if the added substances could be detrimental to electronic assembly board

Circuit cam?

Electronics Forum | Thu Dec 24 09:30:56 EST 2009 | fishingfool

Looking for an answer about file structure on CC. It has been 10 years since I have done anything with CC so bear with me. After you have created a job file that has all the components on it and the polarity parts have a pin 1 indicator, I need to

Pulse Driven Variable Power

Electronics Forum | Sat May 29 02:26:14 EDT 2010 | vinitverma

If you want to vary the voltage to control the motor speed, then this is not the correct way. Though you can use LM317 for reducing the votage (using a 5K potentiometer) which will sure reduce the speed but it'll reduce the torque tremendously. For D
