Can anyone recommend a material which can be used an a bare board: 1. Dispensed via a syringe 2. Mimmic the electrical characteristics of a trace 3. Be processed such that they do not reflow with the solder interconnect 4. Be processed such that the

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

If you are already getting an Advantis flex placer the AC-30 is a no brainer. It will also be a lot easier to balance the line than with another brand chipshooter. We have a video of ours running at http://www.adltech.com. We have had our first Advan

J-STD-001C just requires that the area not be so dirty as to contaminate your product, tools, workspace, etc. If you start counting particles, you're into cleanroom territory. Do a search on ISO 14644-1 for specifics. Actually Wikipedia does a ni

Hello Steve: I work at Navico, a company that makes GPSs and Sonars among other products for recreational fishing. I want to know if our SMT, Thru-Hole and Final Assembly areas need to be in a cleanroom environment? I've worked in another companies

On the Ekra those are called top clamps AKA finger slicers. With the Ekra side clamping means there is nothing on the top of the board. Does your printer have true side only clamping? Or do you need the top finger slicers for the grid-lok to work r

if you cannot spend any money I would say that you either need to add rails or try to increase the squeegee pressure to hold down the stencil while it prints those close pads. But...... Can you put PCB onto some type of carrier that would move thes

Turning off the grid-lok is not an option. I have used the hand inserted tooling in the past..It takes too long to set up and it does not accomodate warped boards. So I am I safe in saying that there is not much I can do aside from change my board d

Do you still have the vacuum plates in? If so, you can set the grid-lok up in the "fixed mode" (not sure what they call it,where it won't set for each board), then you could run without side clamps and the Vacuum should be enough to keep it from movi

I agree, There seems to be quite a bit of negative impression regarding Grid Lok. We have 4 DEK printers outfitted with them. We have had a few problems that were due to warped boards but other than that, they have worked well for us. Fixed tooling
