RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

We now have a source for those much-sought-after plastic SMA finger wrenches! Bracke Manufacturing manager Lawrence Pasternack (not to be confused with that other company's name) sent me an email today saying that Bracke Mfg will be glad to mail anyone who requests them a sample of up to five (5) of the SMA finger wrenches - what a guy! I'm guessing he saw the plea posted here on RF Cafe and on various forums for people looking desperately for the things. The SMA finger (thumb) wrench, known also by its Latin binomial nomenclature of 'digitus divellit,' is a rare breed of tool for the RF / microwave engineer, and appears to be indigenous to industry trade shows like International Microwave Symposium (MTT-S) and European Microwave Conference. SMA finger wrenches are known to be found in jars sitting on display booth counters and in the pockets of engineers and technicians who procure them while in a primal hunter-gather mode. They tend to cling like cockleburs to passers-by and then reappear a short while later in the show-goer's natural habitat of a development laboratory or test station. One might assume due to a proven difficulty in acquiring SMA finger wrenches outside of the trade shows that they are a protected species and cannot be sold on the open market - like ivory and black coral. An attempt to locate 'digitus divellit' on anyone's endangered species list proved futile, though. So, three cheers for Bracke Manufacturing for stepping up and delivering a treasured resource for our brethren. While you're requesting your free SMA finger wrenches, please be sure to manifest your appreciation by checking out their huge selection of RF and microwave components.
Maybe the word is really getting out.
