Graceyt, I know you are being shot a lot of info. Have you gotten any resolution to this problem? I've seen similar problems in our thermal chamber with Demodulation units. The IC, in the module, inside the radio inside the chamber at the top of ou

The minimum via hole size used will have a significant effect on the cost of the board as it limits the number of PCBs that can be drilled as a stack. Not withstanding the radio performance implications of small diameter via holes, typical minimum si

That's a pretty vague question, especially if you count "ID" in the time. In a world where you have AOI or in circuit testing telling you which part has to go, limited thermal mass to contend with and decent equipment, I'd say thirty seconds. On my

Hi All, I would like to ask some help from you. It would be very important for me to identify a bad IC. It is located in a 2,4GHz radio frequency receiver, maybe the IC is some kind of low noise amplifier, but I'm not sure about it. It has 5-pin, see

Hi, I have a SMD radio module that has castellated Pads along one edge of the module. The pick and place machine appears to place them very well but when the boards come out of the reflow oven then up to 20% of them have either rotated a few degrees

Necessity is the mother of invention... The other day I loaned my last bit of high-temp solder to a co-op and never saw it again. Then I had to run a profile and I was in a pickle with no solder. So I ran out to the local Radio Shack to see if the

Hi Chuck We make precision analog and hybrib audio processing equipment for the radio and TV broadcast industry. We have not experienced any problems relating to no-clean reflow since the introduction of the process several years ago. It is known t

Several places I've worked did not allow radios/players of any kind, with or without headphones. The one place that did had a policy that I thought was pretty good - Operators had to be there at least 6 months before they could wear one (that way th
