On the boards, often when they were hit with EOS (electrical over stress) it was pretty obvious from burned/blackened board. He would just open the boards up, lay down a new trace, recover with FR4 (board material). Schematics/Gerbers were often not available... didn't slow him down a bit.
Datasheet Cabtite – The modular cable entry system for pre-assembled cables and cables with and without plugs The cable entry system Cabtite offers maximum flexibility in the cable management of control cabinets, enclosures and machines while saving time, as well as a secure sealing and strain relief of pre-assembled and unassembled cables.
The signal from this would then go directly onto a small antenna, keeping the microwave stuff confined to a very small area of the PCB. Now, onto the iffy bit - would it be OK to use an FR4 PCB? 4+ layer, 0.1mm between top and internal. The ADF5356 datasheet specifies: flexible circuit materials Technical Data Sheet Description DuPont™ Pyralux® AP flexible circuit material is a double-sided, copper-clad laminate and an all- polyimide composite of polyimide film bonded to copper foil. This material system is ideal for multilayer flex and rigid flex applications which require advanced FR4 (FR = Flame Retardent)is a glass fiber epoxy laminate. It is the most commonly used PCB material. 1.60 mm (0.062inch). FR4 uses 8 layers glass fiber material. The maximum ambient temperature is between 120 o and 130 o C, depending on thickness. In China FR4 is the most widely used PCB base material, next is FR1 then FR2. Oct 14, 2013 · Meanwhile, PCB materials with stable Df values on the order of 0.003 up to at least 10 GHz are necessary to meet channel loss budgets in such current high-speed digital applications as network line cards for 40-Gbit/s and faster data rates.
