Hi to everybody. I have some questions. I have a component whit the next description: res. fmf .100 3010 1 S physically, the component have wrote: 22R1. My questions are: what it means? is it a presition resistance? what is the value? Thanks a lo

Buy an electronic counter and simply spool your partial reels to an empty reel. It takes my staff a couple of hours to count every component on partial reels (~50 different values) and I have an exact number rather than an estimate.

I am working with a BGA package. The laminate layer is being modeled as BT-Cu smear. The thermal conductivity of BT is 0.19 W/mK. Does anyone know what the density and specific heat values are for BT?

Are the markings on resistors the actual value? Do AOI machines look for these markings or do they just look to see if a component is present and placed well? Can anyone attest to the solderability of upside down resistors? Can anyone argue that u

Dang!!!! ;P Hey, wait a minute!!! The BIG DOGS believe "it's a service, not a problem". Are you saying that they think that you're fortunate to get parts falling off of the boards? So there cracks are part of the value added? Whee!!

Hey, I would suggest using lead-free solder and lead-free components. This would give your kit the "green label". I dont want the sample if you this suggestion doesnt value add to your project good luck

For rigid boards, look here: http://www.standardpc.com/ipc4101.htm Google ...ipc 4101... to fill-up your table.

Hi I don't understand your question. I do understand dielectrics and flex. What is "dielectric resistance". I might know it by a different name. YiEngr, MA/NY DDave

Hi http://webvision.ipc.org/scripts/mgrqispi.dll?APPNAME=IPCWEB&PRGNAME=TOCFRAME&ARGUMENTS=-N,-N,-A,-A,-N50 And then look at 4202 and some of the others. YiEngr, MA/NY DDave
