Yo Dilbert, you don't say where in the real world you are located, but Ul, CE, and such pretain to electrical, and fire safety codes. The min required code is up to the local authority having juristiction over your facility. It is not a SMT industr

Does anyone know there a standard matrix of clearances part to part for Class 2 and Class 3 board design. IPC does issue a preferred matrix but they are so liberal they not so useful in the real world. Any suggestions would really be appreciated.

Nice attitude Newbie, real mature of You. This guy had a problem, and thank God someone helped him. If all of us knew everything, as You do, there would be no use for this web site. Please pull your head out once and a while.

Hi, Thanks for the info, and this really helps a lot. So the change over time is really just loading the different feeders? That does not seem like too much trouble. How does the X and Y correction on the HSP effect real world placement accuracy? D

This is what I use: http://www.omega.com/Temperature/pdf/5TC.pdf or http://www.omega.com/Temperature/pdf/5LSC_5SRTC.pdf The 36 and 40 AWG sizes are ideal (TT insulation.) $430 for 9 thermocouples seems real high.

Agreed. You will find different part manufacturers have different coplanarity specs. In fact I have on supplier that calls out 7 mil max coplanarity. Then factor in board bow and twist and it becomes a real joy.

I have seen the solder shoot out at least 4"-6" from both the leading and trailing edge when this happens. If the open pockets are real deep you may want to use a turbulent/chip wave for soldering, sometimes this leaves bridges however.

Hi Friends, I had a PCB with polymide material with nickle tin plating on it. I had real hard time to do hand solder. I am asking help if any one have any experience with polymide material.

I would like to find out what is one of the most common cleaning solvents used in screen printers. By this, I mean which solvent is used in the solvent tanks to clean under stencil in DEK & MPM's etc. Please, no sales guys, only real users. Cheers,
