Dave, you are right you would expect the soldermask to be higher than all SMT pads on the pcb if it is higher on the fine pitch components, but the other areas of the board do not concern me as much as the fine pitch areas. The pads on all the other

| Are the terms "uBGA" and "Fine Pitch BGA" synonomous, different all-together, or is Fine Pitch BGA a subset of uBGA? Thanks. | | Steve | Steve: �BGA�: Micro BGA�. A brand name for a fine pitch BGA from Tessera. Fine Pitch (1) In SMD: Surfa

Square apertures can have a larger area within the same space than a round aperture. You can buy IPC 7525 from IPC. The theory you are missing has to do with: * Aspect ratio * Area ratio Search the fine SMTnet Archives for background on these rati

What has been your experance with fine pitch parts taped and reeled? Will I have lead problems?

Check the fine SMTnet Archives. Some people have a difficult time using the fine Archives, if so, email me and I'll try to help further.

I am interested to know what people prefer for fine pitch packaging. Tape/Reel or Waffle tray for .031", .025", .020", .015" pitch components? What is the most robust packaging (i.e. fewer bent leads, etc.) Chuck

What do you all do to fix coplanarity on fine pitch QFPs? I know that the best thing would be to send them back to the vender, but what about the when you gotta use them? Straightening by hand seems to be so time comsuming. Any better ways? Larry

Is there a chart available to use in identifying the pitch of fine pitch components - one with which a components leads could be matched ( similar to that of the component's "footprint" on the pcb ) ?

Hi I found it's hard to attach thermocouple on profile board at fine pitch component by high temp solder. Does any one know the good way to do it? Thanks in advance. Dave

Hold it!!! Call Bob over at Tri-Metal Fabricators and ask him to make you one for about 10% of the price a fine OEM would charge. Might not a a fancy anodized finish, but at the end of the day, it'll hold yer trays just fine.
