Another Gerber File?

Does Powerlink allow me to have heavy copper only on a few traces by utilizing an extra Gerber file?

My guess is you would create a layer for each different thickness. From reading the article current carrying vias would benefit a lot from this. Basically defining an additional layer in the layer stack associated with those vias would give you this. This is not unlike what you do when you want peelable mask on parts of the PCB.

That's what I figured, sort of like when you do a carbon layer for for rubber keyboards.

Yes, that's exactly what I meant, PCB packages are layered 2D by design, so this is the most efficient method.

The PowerLink can be defined as you described by adding an extra Gerber file such as 1A, 1B, or what ever naming convention makes sense to you.  The often easier alternative is to use the fab drawing to identify areas of thicker copper.  Typically these areas are obvious because the track widths are normally much larger.

A different concern

In my personal experience, when designing PCBs the concern is centered around high frequency effects.  This is a different realm and the artcicle is very informative.  I think that one often stays away from high current becuase of the typical types of copper thicknesses that are often used.

I have worked on older thick copper trace boards on aerospace boards in the past, but this is so much more refined and thought out than older boards. The boards used these for current, not signal.

Cost Impact

I definitely see the advantages of the higher current carrying capacity and improved thermal management.  Copper does have a cost associated with it and I was wondering what the cost impact would be.  In what situations would this technique be more cost advantageous versus using other, more conventional techniques?

Hi Greg,

Heavy Copper circuitry is something all engineers should be considering in their design.  In PTH minimum thicknes should be 1.2 mils.  Heavy copper tracing can not only add strength to your traces, it also aids in convection cooling.  There is obviously a higher cost involved because of higher plating times however in situations where failure is not an option, its the best way to go.  We manufacture heavy copper circuits for military applications mostly as well as high voltage systems.  Bottom line if you need high reliability.. go with a heavier copper.  Check out www.omegacircuits.com for more info.

Greater current carrying capacity

It is nice to have more advanced and high endurance PCBs out there, with more Ampere rating. I recall working with comercial PCBs for my final year project. The H bridges of a BLDC motor were made by us on a commercial PCB. When the load used to increase(around 16 amps) the copper wires used to melt and burn the PCB. I hope having more powerfull PCBs will cater for higher power applications in Industries.

Finding a great printer in Canada sometime is quite difficult. You want the best price and service out there. Here are some of my suggestion: Canada Printer | Toronto Print Quote | Calgary Print Quote | Winnipeg Print Quote | Montreal Print Quote | Regina Print Quote | Saskatoon Print Quote | Quebec Print Quote | Ottawa Print Quote | Edmonton Print Quote | Vancouver Print Quote |

If you want to find sticker printing companies which could do die cut, circle, and other types of stickers. Here are some of my best recommendation: custom sticker print quote | Print Custom Stickers | Sticker printing company. They provided the best quality and price out there.

If you are a print broker. You need to have a fast turnaround and most importantly, lowest print price on the market. Here is my list: Best Print Trader | Lowest Price Printing Wholesale | Print Outsourcing | Print Broker Trade

For some other alternatives for great printers. Here it is: Custom Printing Services | Print Companies | Best Printing Company

Some of the US printer list are here: Atlanta Printer Quote | Boston Print Quote | Chicago Print Quote | Arizona Print Quote | Miami Print Quote | New York Print Quote

If you are a printer yourself, you might need this. Best printer management software: Print Company Software | print software tool | manage print shop software
