Hi all, after some discussion on Yahoo group list I was asked by some hams for more details about the ESD mats and ESD tools for safe Elecraft kits assembling.
I do not understand all of the huge discussion on some forums and threats about something which cost $25-$30 (compare to invoice for K3S kit...) and which solving the ESD task forever...;) so I hope it helps: 1. The top layer must be dissipative 2. The bottom layer must be conductive 3. Its nice when its oil, grease and solvent resistant, high temp resistant, acid proof and knife cut proof material. 4. Mat must be connected to ground thru 1.5M resistor, NOT ditectly in order to thru body current limitation if an accident! 5. Wristband is connected to mat in normal cases also thru 1.5M resistor. Just few basic hints for all who would not like to just faith to be "lucky user" when working with boards like K3S kit etc. More info you can find here in my article: www.eham.net/ehamforum/smf/index.php/topic,84533.msg616867.html#msg616867 There is complete set with high resistant profi grade mat http://www.eham.net/reviews/detail/10661 We still have them in radioclub´s stock available as we bought from supplier big package in order to get good price. So don ´t hesitate to drop me an email if you want them. 73 - Petr, OK1RP STMicroelectronics Laboratory test equipment, Design and application, Prague, CR www.st.com ----- http://ok1rp.blogspot.com -- View this message in context: http://elecraft.365791.n2.nabble.com/Elecraft-kits-assembly-using-ESD-protected-bench-tp7606375.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
