MIL-PRF-55110 Printed Wiring Board, Rigid, General Specification ForThis specification establishes the performance and qualification requirements for rigid single??sided, double??sided, and multilayered printed wiring boards with or without plated through holes \(see 6.1\). Verification is accomplished through the use of one of two methods of product assurance \(QPL or QPL/QML\). Detail requirements, specific characteristics, and other provisions which are sensitive to the particular intended use are specified in the applicable master drawing.

3.3

3.3 Product assurance requirements. This specification contains two different methods of product assurance for

printed wiring board compliance. The two levels of printed wiring product assurance are QPL (see 3.3.1) and

QPL/QML (see 3.3.2).

3.3.1

3.3.1 QPL product assurance. Product assurance procedures (see A.4.5.5.2) shall be made available to the

qualifying activity in order for the manufacturer to be listed on QPL�55110. The product assurance procedures shall,

as a minimum, consist of the items outlined in A.4.5.5.2. The manufacturer shall ensure the product assurance

procedures reflect the actual product assurance practices of the manufacturing location. The qualifying activity shall

be notified within 14 days of any changes to these procedures. The product assurance procedures shall also be

available upon request of the qualifying activity.

3.3.2

3.3.2 QPL/QML product assurance. A product assurance program for QPL/QML printed wiring board furnished

under this specification shall satisfy the requirements of appendix B.

3.4

3.4 Letters of interpretation and policy. Letters of interpretation and policy applicable to this specification shall be

approved in writing by the preparing activity or qualifying activity. All letters of interpretation and policy applicable to

MIL�PRF�55110 written prior to the current date of this specification are not applicable to this revision. All

subsequent letters of interpretation and policy letters are valid only until the next document change action

(amendment or revision).

3.5

3.5 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally

preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the

operational and maintenance requirements, and promotes economically advantageous life cycle costs.

3.6

3.6 Certification of conformance. Unless otherwise specified by the contract or order (see 6.2), a certificate of

conformance for compliant printed boards shall be forwarded to the acquiring activity (see 6.5.1). When a certificate

of conformance for compliant printed boards is supplied, it shall include the following information, as a minimum:

Manufacturer's name and address.

Customer's name and address.

Manufacturer's CAGE (Commercial and Government Entity) code.

Printed board description, including classification (type and base material), specification number with revision

and amendment level, master drawing or other identification number, and the applicable design standard.

Lot date code.

Quantity of printed boards in shipment from manufacturer.

Statement certifying printed board conformance to this specification, the master drawing, and the contract or

order.

The date of transaction.

The name of the company official approving the certificate of conformance. The manufacturer shall have a

method for authenticating the approval of certificates of conformance for printed boards compliant to this

specification.
