FOREWORD
This standard is intended to provide information on the generic requirements for organic printed board design. All aspects
and details of the design requirements are addressed to the extent that they can be applied to the broad spectrum of those
designs that use organic materials or organic materials in combination with inorganic materials (metal, glass, ceramic, etc.)
to provide the structure for mounting and interconnecting electronic, electromechanical, and mechanical components. It is
crucial that a decision pertaining to the choice of product types be made as early as possible. Once a component mounting
and interconnecting technology has been selected the user should obtain the sectional document that provides the specific
focus on the chosen technology.
It may be more effective to consider alternative printed board construction types for the product being designed. As an
example the application of a rigid-flex printed wiring board may be more cost or performance effective than using multiple
printed wiring boards, connectors and cables.
IPC’s documentation strategy is to provide distinct documents that focus on specific aspect of electronic packaging issues.
In this regard document sets are used to provide the total information related to a particular electronic packaging topic. A
document set is identified by a four digit number that ends in zero (0).
Included in the set is the generic information which is contained in the first document of the set and identified by the four
digit set number. The generic standard is supplemented by one or many sectional documents each of which provide specific
focus on one aspect of the topic or the technology selected. The user needs, as a minimum, the generic design document,
the sectional of the chosen technology, and the engineering description of the final product.
As technology changes specific focus standards will be updated, or new focus standards added to the document set. The IPC
invites input on the effectiveness of the documentation and encourages user response through completion of ‘‘Suggestions
for Improvement’’ forms located at the end of each document.
