Does anybody have information on the minimum spacing required between BGAs (i/o counts close to 696)to avoid damage during rework? Also, on the keep out requirements between CSPs (o.5 mm pitch); between CSPs and BGAs. thanks in advance for your hel

Yes, I realize that COB isn't really SMT (it is on the surface), but where can I get some free (IPC has some stuff for sale), fast info. about IC pad spacing for COB? Thanks

We have to mount our SMD devices 0.1 to 0.4 mm off the pcb PCb substrate to compensate for thermal stressing in a Space enviroment. Has any one any ideas or contacts for dissolvable pads. this only applies to leadless components

The tightest spacing between neighboring 0201 components assembled was 8-mils. Please refer to the response for the query entitled �Minimizing Tombstoning Defects� posted by martys, as the response provided there is also relevant to address this que

sometime hand solder can cause also. no necessary have to be paste n reflow.:) now i'm facing bridging on 0402 components pads. any suggestions on spacing distance as we're going to re-design the pcb.

Is anyone has experience on problems with press-fit on Ni/Au board finish. Connectors pins are SnPb finished. I am particulary interested by experiences or documentation in very agressive environmental conditions (avionics or space buisness) Thanks r

How can I read a MIDI (.mid) File and play sound to a speaker, my space is restricted circuit must be as smal as posible. (do i need a microcontroller with a rom to store the sounds or can i program it all onto a single IC?)
