RF surface mount assembly

RF surface mount assembly | 20 September, 2000

RF pcb is all gold with no typical land patterns and multiple surface mount components sharing the same pad. IPC-610-B doesn't speak to inspection criteria. The problems I'm seeing are, insufficient solder, skewed components. Some of the pads have holes in or attached to them. Absolutely no solder mask at all on these pcb's. Could you give me some direction here. Thanks in advance, Rich

Some RF components are made in copper in weird spiral and parallel strip-line shapes.

I'd either: * Send the boards back to where ever you got them and tell that bird brain to use SM-782 pads and practices. ... OR * Get the bird brain that sent you the boards to sign a waiver stating that the excecution of the design is as expected and that you need not concern yourself with apparent workmanship issues.

Guess which I prefer? Good luck.

On the money as usual!

(Your subtle approach is something to behold. Much like my approach, which has gotten me into more grief over the years than I should be allowed to have.)

Beyond keeping one in hot water, I found that this subtile approachs virually assures that you don't get promoted to the point that you get an opportunity to ruffle the feathers of the pimadonnas.

Musta breathed too much flux fumes!!! Don't want him talkin' to Mr. Highmuckymuck!!!
