Circuit Board Shields:
Answers To Some Often Asked Questions
What sizes are available?
Standard sizes are from .50" x .50" (12.7 x 12.7) to 12.00" x 24.00" (304.8 x 609.6) at .25" (6.35) increments.
What heights are available?
Standard heights are from .13" to 2.00" (3.3 to 50.8); by simply changing the cover height, any specific height is attainable.
What shapes are available?
Squares, rectangles, and L-shapes are available.
Do the different series and part numbers relate to the physical aspects of the parts?
Yes, each series number indicates a different fence height; the minimum height of an assembly using the specific series is indicated by the series number:
10 SERIES = .13" MIN. (3.3)
20 SERIES = .20" MIN. (5.08)
40 SERIES = .40" MIN. (10.16)
50 SERIES = .50" MIN. (12.7)
80 SERIES = .80" MIN. (20.32)
Taller assemblies using a specific series number can be attained by increasing the cover height; for example, a 1" (25.4) tall assembly can be achieved using the 50-CBS series fencing by increasing the standard cover height by .50" (12.7).
Each specific series sub-number indicates a different fence configuration relating to mounting pin spacing and standoff availability.
Suppose I need to run a lead wire into an assembly?
Clearance notches can be added to the bottom of the fence material to allow wires to run to components that will be under the CBS assembly.
Can access holes be added to the cover?
Yes, access holes can be added to allow for component adjustment when the cover is assembled to the fence.
How do I deal with heat dissipation?
Ventilation holes can be added to the covers; page 7 of the Style CBS design guide shows our standard ventilation hole pattern which can be added without tooling charges.
When would I need the optional securing dimples?
In most applications, the Style CBS fence design provides sufficient holding power without the addition of securing dimples in the cover; when severe shock or vibration are a consideration, dimples may be required.
What are the available materials?
The standard material is a .015" (.38) thick pre-tinplated steel, which is readily solderable; other materials are available; please consult the factory.
Can I get samples?
Yes, a reasonable amount of samples may be requested from the factory.
What is the standard lead time?
For samples, the standard lead time is ship 1-2 weeks after receipt of request.
For orders of 100pcs or less, standard lead time is ship 3-4 weeks ARO.
For larger volume orders standard lead time is ship 4-5 weeks ARO.
(These are our current lead times and are subject to change).
