PCB-RULER-ND: Metric Side Rev 1 (March 2016) 12 inch (~30.5cm)

Our aim was to create a reliable and accurate PCB layout reference tool. We tried to include as many useful features as possible.

1.25” x 12” (31.75mm x 30.48cm) ° 0.062” Thick - 1oz Copper (~35µm) ° ENIG finish (Electroless Nickel Immersion Gold) ° Weight ~ 1.16oz/32.9gm

Footprints of the eight most popular IC packages

(used by our manufacturers) including a few

extra… (i.e. SOT-23-5 and SC-70-5 also cover the

footprints for the 3-lead versions)

Hole examples with 0.5mm

thick annular rings, so the

1mm diameter hole has a

2mm diameter annular ring.

The heights of these examples were

adjusted to be exactly as listed. The

Stroke font thicknesses shown are

calculated height/7 or /10, so 2mm/7

=0.286mm thick & 2/10=0.2mm.

This ampacity chart shows the maximum current an external

trace width (in millimeters) can pass and only raise its

temperature by the listed value in centigrade.

As noted, for internal traces, multiply the trace width by 2.6

to carry the same amount of current.

When calculating per IPC-2221(A), the copper thicknesses

listed on the MIL side were used.

The metric hole examples are

centered; the ruler should

hang straight when hung.

Annular rings = 0.6mm thick.

The trace width examples, on this side, were

positioned on the edge so they could be placed

over a PCB trace to estimate what width was used.

A bit of geek humor. *

The hole examples on the

MIL side were made without

annular rings for contrast.

Again, we

are here for

you, always.

The trace width examples were made

with both MIL & MM on both sides for

ease of comparison between the two.

Many customers use these services daily, however others have no idea we could help

them with these services. Some not listed are custom: fan connections, heatsinks,

transformers, power supplies, die-cutting of adhesives & thermal interface materials.

Current Ratings for Alpha Cables

The maximum continuous current

rating for a cable is limited

by conductor size, number of

conductors contained within the

cable, maximum temperature

rating of the cable, and

environmental conditions such as

ambient temperature and air ﬂow.

To use the current capacity chart,

ﬁrst determine conductor size,

temperature rating, and number

of conductors from the applicable

product description for the cable

of interest.

Next, ﬁnd the current value on the

chart for the proper temperature

rating and conductor size. To

calculate the maximum current

rating/conductor, multiply the

chart value by the appropriate

conductor factor.

The chart assumes cable is

surrounded by still air at an

ambient temperature of 25°C.

Current values are in RMS

amperes and are valid for copper

conductors only. For conditions

other than speciﬁed, contact

Alpha Technical Support at

1-800-52-ALPHA.

Note: Current ratings are intended

as general guidelines for low-

power electronic communications

and control applications. Current

ratings for power applications

generally are set by regulatory

agencies such as UL, CSA, NEC,

and others.

Doc Rev 9-MAR-2017

Changes from Rev 0 (labeled DEC 2015) to Rev 1 (MAR 2016)

Metric Side, Right

Added the

0.6mm text

example

Changed the copper thickness

unit from oz to µm (only on

Metric side). Probably should

have rounded to 17.5, 35, and

70µm (maybe in another rev?)

Lowered the table

to match MIL side

Added Fiducial

This asterisk refused

to stop poking the B.

The new versions are

getting along well.

MIL Side, Left

* It is humorous how many

don’t get that this is a joke

Added space between

the copper test points

and silk screen on this

side as well

Added three 20MIL

text examples and

a 25MIL

Changes from Rev 0 (labeled DEC 2015) to Rev 1 (MAR 2016)

MIL Side, Right

Produced with Mentor Graphics software

The trace width

examples were spread

out on this side as well

This asterisk was also

crowding and fighting

with the B so they were

given space and are far

happier silk now

Added Fiducial

Changed the

text to match

the Metric side
