Sand is not a great conductor, compared to copper. Never heard of using the stuff on RF boards. Our board fabricator uses Dupont CP100, now CP101, [or something like that cuse who's going to check?] when plugging via on cheap boards. Your board fa

Have the PCB fabricator use a conductive paste to fill the vias and then finish by plateing over the via. Make sure it's coplanar to the side they're on, usually secondary side for discretes. PT

Dear Sumote, I would suggest DESCO ESD safe heat gloves, we are using them at our facility, these gloves have a polyester exterior fabric with conductive fibers to ensure static protection. Inner lining constructed of material for use in heat of 200�

PCB designers specify the application of solder mask [eg, varnish, solder stop mask, solder resist, etc] to fabricators to reduce the potential of bridging between two conductive traces during assembly soldering processes [eg, wave, reflow and hand s

In describing a bare board, you need to talk about base, laminate, and conductive materials. Common laminate materials are: * Glass fabric * Cotton fabric * Paper Common NEMA grades of technical laminates are: * Glass Fabric Grades: G3, G7, G10,

A common way to add traces to a fabricated board is to print polymer thick film [PTF] conductive ink. PTF suppliers are: * Du Pont de Nemours, E. I. & Co. - Research Triangle Park, NC * Ercon, Inc. - Wareham, MA * Dow Corning� * Asahi Chemical Res

This might be a trival mundane suggestion but try to use non conductive plate to hold components. Probably even made of the pallet material. I am sure your pallet fabricator will have tons of scrap and he can help you find one. T

You seem to pretty far from shore to begin thinking about boats and floatation devices. Most laser trimmers are used by: * Semiconductor fabricators * Resistive component fabricators * Hybrid circuit assemblers Component fabricators and hybrid [

Hi Steve ... There are arguments between fabricators and thermal relievers about adding non-connected copper tabs to barrels in hopes of providing thermal relief, but that's not what you're talking about, I believe. I don't foresee an issue moving t
