## Current Capacity of 2 traces.

Only if they are spaced wide apart. There are plenty of online current carrying calculators which will give the correct width against ipc rules. Keith

## How to decide Track width accourding to current??

You could look at which calculates ipc-2152 and ipc-2221 values to find out the difference. Keith

## Need clarification for Fabrication and Standard ??

For your info, a list of ALL the major PCB related ipc specs, should be in this lot somewhere: 1601: Printed Board Handling and Storage Guidelines 2141A: Design Guide for High-Speed Controlled Impedance Circuit Boards 2152: Standard for Determining current Carrying Capacity in Printed Board Design 2221A: Generic Standard on Printed Board Design

## 220 V AC to 5V AC planer PCB transformer design? Output current is around 10mA

Use a trace width is based on the ipc-2152 current Capacity and Heating of Traces (Use the Saturn PCB toolkit to get your figures).

## pcb industry specifications

You also may want to review the related edaboard discussions.

## Current density hyperlynx PI simulations

current limits can be calculated with the ipc-2152 formulas. conservative values are about 10-15 A/mm^2.

## PCB various track size?

Most people I know who do PCB design (and I know a few) use the Saturn Toolkit and have it on their desktop, If you are going to do PCb design I would reccomend you download it and use it. Temp rise above ambient, I use 10 degrees to play safe. But for commercial you can use 20 deg C. ipc-2152 is the standard for current capacity.

## [Moved] Please check my board file

Use the Saturn toolkit. Saturn PCB Toolkit Help ipc-2221 current tables HAVE BEEN SUPERCEDED BY ipc-2152

## Trace width and current: IPC-STD-275?

ipc-2152 is the most up to date standard for current carrying capacity Yes. Unfortunately the ipc Document Revision Table does link to the new specific Standard for Determining current Carrying Capacity in Printed Board Design in the ipc-275 and ipc-2221 entries.

## Regarding PCB, high current

Here is a free tool for trace currents: TrAMP V1.1 You will need to use multiple via where large currents change layers: Other free tools:

## Need BGA design rules

Am about to redesign a current project but will be using BGA's instead of QFP's, anybody got the relevant ipc spec they would like to upload? Failing that point me in the right direction. Many Thanks Mozzer

## How to determine the appropriate width of the tracks while designing board?

Look up ipc-2221A standard in this forum. In that standard there is a chart that tells you the trace width from the current, copper thickness (in oz) and ambient temperature. Also, Google "trace width calculator" - there is a number of web-based calculators for the trace width. Here's an example of the trace width calculator: www.geoc

## Trace width vs Current

I'm trying to realize a trace that is able to manage 15 A average with a temperature increase of 20°C. The trace is embedded in a thin substrate of polyimide. Which is the minimum trace width? All the articles talk about external trace on FR4. All the graphs (ipc) show the behavior of the external trace. Who can give me more information? Thank
